SYNOPSIS
The steady growth of hominin cranial capacity during the Lower and Middle Paleolithic (L/MP) supported the
emergence of controlled vocalizations, orchestrated mimetic techniques, deductive tracking skills and exogram-
matic information storage abilities. ‘Exograms’ are defined as memory traces stored outside the brain as con-
sciously-sequenced information packages meant to stabilize abstract calibrations of reality. The first instances of
their use document the universal emergence of a species-specific objective state of consciousness. Although the
ability to produce them was a biological development, the transmission of exogrammatic meaning became cul-
turally-conditioned. As all the faculties listed above were in place long before the Aurignacian, the Upper Paleo-
lithic (UP) ‘revolution’—unlike the L/MP transition—cannot be attributed to changes in the size or shape of the
cranium. The period was rather characterized by accelerated cognitive specialization to deterministically-pre-
dictable cultural niches constructed in unreliable environments. By adapting to their calibrated models of reality,
archaic populations underwent rapid physiological/psychological transformations. It is contended that the UP
‘creative explosion’ illustrates the attempt to counter cognitive losses inherent in entanglement, cumulative cul-
tural evolution and incipient self-domestication.
Unfortunately, by considering the cumulative type of cultural evolution as the ‘natural choice’ of all cognitively
modern humans, gene-culture coevolution theory implies that the ‘ratcheting’ of innovations is the only index of
‘progress.’ In the modelling of the theory the stress is placed on social complexity, the absence of which would
render small and isolated populations vulnerable to the ‘treadmill effect,’ the inevitable consequence of impaired
social learning. However, the anthropological literature documents isolated hunter-gatherer groups that have
developed intricate exchange networks that do not necessarily rely on technological innovation and function only
in low demographical settings. Not only that the biases upon which transmission depends in cumulative cultural
evolution—prestige, skills, success—are unknown, but certain ‘leveling mechanisms’ inhibit these very parame-
ters and thus, no cultural models can rise to prominence. Contrary to the predictions of the theory, these societies
do not seem to be plagued by cultural ‘loss’ and, instead of hopelessly running the treadmill and living in poverty,
they have developed egalitarian and, to an extent, ‘affluent’ societies.
Populations following a non-cumulative type of cultural evolution—known in anthropology as ‘immediate-
return’ hunters-gatherers—are often described as ‘pedomorphic,’ due to their markedly neotenous morphological
features and cognitive attitudes. On the other hand, populations that follow a cumulative type of cultural evolution
are surprisingly ‘robust’ phenotypes. In the case of the latter, a cultural ‘sudden jump’ seems to have occurred
during the Late Pleistocene which, in its turn, resulted in the entrenchment of archaic behavioral traits and the
establishment of hierarchical societies. Conversely, with certain isolated hunters-gatherers, a cultural ‘disentan-
glement’ seems to have taken place during the Early Holocene. The adoption of a cultural ‘primitivism’—imme-
diate-return subsistence—offered a degree of evolutionary flexibility that allowed for a neotenal leap. This, in its
turn, enabled the reduction of archaic behavioral traits and the emergence of egalitarian societies.

INTRODUCTION
The ‘ABC of Modernity’ Reconsidered
Unfortunately, most approaches to the development of hominin symbolling abilities adopt a linear under-
standing according to which, abstract representations are classified as expressions of inferior cognitive abil-
ities and iconographic illustrations as self-evident signs of higher cognition.
According to the paleosemiotic interpretation pioneered by E.V. Culley (2016; Supplementary Graphic
Material [SGM] p. 2) – notches, engravings and abstract geometrical patterns are labeled as ancestral and
emergent symbolling abilities, while naturalistic/illustrative engravings and paintings are categorized as
fully-mobilized expressions of cognitive modernity. Culley – without explaining the reason – attributes all
the Upper Paleolithic ‘emergent’ abilities to Neanderthals and the ‘mobilized’ symbolling faculties to ‘ana-
tomically modern humans.’
Cognition, anatomy and behavior are presented as inseparable parts of a presumed punctuation that had
bypassed the cognitively, anatomically and behaviorally inferior Neanderthals. However, the recent discov-
ery of arguably pre-Homo sapiens sapiens paintings in La Pasiega Cave (Hoffman et al. 2018) casts doubt
on Culley’s linear classification: apparently, Neanderthals were in the possession of fully-mobilized symbol-
ling abilities long before the Upper Paleolithic ‘cognitive explosion,’ more than 66,000 years (66 ka) ago.
Cognitive expressions that predate Period F in the table (123-191 ka) are simply ignored and not even
considered worth to be designated as ‘ancestral.’ However, the deliberate engravings on a tibia fragment of
the forest elephant from Bilzingsleben, Germany (>325 ka, Bednarik 2014a) or the stone plaque bearing
seven engraved lines from Wonderwerk Cave, South Africa (c. 300 ka, ibid. 2013) display the same cognitive
standards that define ‘emergent’ symbolling abilities.
Adding a theoretical Period G (>350-191 ka) to the table and defining its products as witnesses to an
emerging symbolling ability is recommended. However, by doing so, we would only extend the linear con-
cept backward in time, without addressing the problem of the transition between emergent (abstract) and
mobilized (iconic) representations. But the archaeological record documents both Lower and Middle Paleo-
lithic (L/MP) examples of iconic understanding and Upper Paleolithic (UP) instances of abstract represen-
tation, which means that the relationship between them is rather complementary than linear. For example,
the Acheulian naturally shaped scoria pebble inserted to the Period G line/Levantine column of the table
(Goren-Inbar 1986; Bednarik 1994) points to the existence of such an iconic sense at already 250 ka ago
(SGM p. 2).
By the same token, the anthropological literature mentions cultures that favor abstract patterns over nat-
uralistic illustrations (Sreenathan et al. 2008) to such an extent that, until recently, it was firmly believed
that people belonging to such cultures were so primitive that they did not even develop iconographic under-
standing – a presumption that has implicitly presented them as cognitively not yet ‘modern.’ I would suggest
the opposite: cognitive modernity seems to have been in place for more than 300,000 years, at least in its
species-specific biological aspect, which had assumed various culture-specific variations during the last tens
of millennia.
Cognitive expressions that were not carved in stone but, say, drawn in sand or painted hundreds of
thousands of years ago did not survive the test of time. Ocher was consciously hoarded during the Lower
Paleolithic (Bednarik 2013) but, unfortunately, we will never know what was it meant for.
The transition from abstract to iconic cannot be dated, mostly because there are no clear-cut abstract or
iconic ‘periods.’ For example, dots, lines and naturalistic depictions are featured in both the Neanderthal
illustration from La Pasiega and in the famous stag mural from the Axial Gallery in Lascaux (Taylor 2017).
Therefore, instead of ‘periods,’ cultural contexts in which either abstract or iconic representations were
preferred should be considered.
Any inquiry into the origins of paleoart should focus on why?, rather than on when?. Undoubtedly,
iconographic potential was present long before the Aurignacian, when it underwent a ‘big-bang’ and became
obsessively applied, never to be discarded again. Why did the application of iconic abilities become suddenly
G.F. Steiner

important, as opposed to L/MP contexts when, although the ability was arguably extant, it was not regularily
resorted to?
I hypothesize that the etiology of iconic expression – that is, its sudden preference over abstract
representation – lies in altered environmental contexts that trigger out the application of this latent cognitive
potential. By environmental change I do not necessarily mean climatic fluctuations – although these must
also be considered – but mostly transitions of a cultural nature.
The impact of such changes becomes evident in the well-known examples of chimpanzee and bonobo
cognitive abilities, as summarized by Roffman et al. (2016 and references therein). Why Kanzi’s cousins in
the African rainforest do not draw or develop complex tool technologies, given that the ability to do so is,
arguably, extant? Why is it that such a potential becomes realized only in artificial – laboratory, zoo, captivity
– environments? Apparently, externally-imposed criteria trigger out cognitive and behavioral responses that
do not take too much of an effort in the case of primates. In human proximity and, with a little help from
researchers, drawing and tool-making become ‘meaningful’ – the rewards that follow the exhibition of such
abilities are rather social – like, displays of affection and appreciation – than restricted to food. Punishment
is usually not considered in primate experiments, in contrast with the training of the infamous painting
elephants of Thailand, where it assumes a central role. Moreover, these elephants do not apply a latent
cognitive ability but follow blindly human commands (Scharfstein 2006; Sreenathan et al. 2008).
Another example of extant cognitive abilities that manifest themselves only in an artificial environment
is the already mentioned case of certain ‘primitive’ hunters-gatherers. When I visited the Andaman Islands
in 1994, the Jarawa exhibit at the Port Blair museum presented them as Stone Age ‘savages’ engaged in a
perpetual struggle for survival for which they were cognitively, behaviorally and technologically unfit.
Recently, the Andamanese tribes were featured in scholarly articles as examples of isolated groups exposed
to cultural loss because of their reduced demographical strength and presumed lack of social complexity
(Henrich 2004). In the past decades, however, civilization has reached them in the form of the Andaman
Trunk Road. Anthropologists have also made contact and discarded some of their earlier misconceptions and
presumptions. But, in lack of evidence, the researchers were still firmly convinced that the Jarawa had not
developed complex symbolling faculties, the measuring stick of which is the absence/presence of the ability
to produce Lascaux-style naturalistic ‘art.’ They were thus considered to be only half-way to ‘modernity,’ at
a primitive stage of abstract doodling.
One day, a Jarawa boy was hit by a truck and dispatced to the hospital. Imagine his trauma, which could
not have been less than that undergone by a UFO abductee – the monster that hit him while walking on the
back of the black asphalt serpent, and the white-clad hospital staff doing strange experiments with his body,
accompanied by the beeps of flashing instruments. He was given pencils and paper, nurses do that with child
patients. The boy Emmy started to draw feverishly, mostly plants and animals from his natural environment
(Sreenathan et al. 2008). The images were drawn with an eye to detail and at an artistically sophisticated
level (SGM p. 4). His ‘art’ was the product of his uneasiness in a bizarre new environment, and the plants
and animals of his trusted jungle-world were reproduced with accuracy and detail, giving voice to his
yearning for something lost.
Did the boy effectuate an evolutionary leap and, all of a sudden, become cognitively modern? Of course
not: after investigating the incident and, to their surprise, anthropologists discovered that Jarawa children do
habitually trace naturalistic forms in sand or mud. Only that this habit was considered a meaningless
childhood pastime by the elders, who cultivate exclusively abstract representational skills because, as they
explained, only such patterns possessed meaning (ibid.). In a strange hospital environment, the childish
ability for iconic representation became, all of a sudden, imbued with significance.
I would suggest that the Eurasian Upper Paleolithic (UP) obsession with detail (understood as local
processing bias by Spikins et al. 2018) and stress on iconicity might be explained with the degree of
elaboration of an artificial, i.e., cultural environment in which ‘childish’ abilities had suddenly gained in
importance and meaning – I will return to the role played by children (Snow 2013) because of their specific
cognitive faculties (Charlton 2006) during the Western Eurasian UP, later on.

A parallel can be drawn between the contemptuous portrayal of the Andamanese – who were implicitly
perceived as cognitively inferior – and the Neanderthals, the perception of whom was overtly biased, from
the very first moment of their discovery (see Saniotis and Henneberg 2010-11). Such brutish cavemen – and
who looked so different from us – could not be associated with superior cognitive expressions that we love
to think are exclusive to us. ‘Us,’ in this case, must be the UP skeletal remains of people who would closely
resemble those of 19th and 20th centuries European ‘moderns.’ Our search for such remains was thus highly
biased and paleoanthropologists were eager to find such ‘modern’ remains and inclined to exaggerate their
antiquity. Therefore, as Bednarik (2007, 2017) points out, Gravettian specimens were given Aurignacian
antiquity and declared ‘anatomically modern’ Cro-Magnons. Conversely, archaic ‘Neanderthaloids’ were
pushed back in time. Only that, because of the mistaken dating, there was no smooth osteological transition
between Neanderthals and these anatomically modern humans (AMHs). The ‘replacement hypothesis’ was
constructed in order to explain the fossil gap.
The sudden appearance and ratcheting of grandiose cave art was brought up as the unquestionable proof
of the cognitive superiority of these exotic Cro-Magnons – again, because of no apparent transition between
the presumed lack of symbolic thought with Neanderthals and the suddenly overwhelming evidence of it, at
c. 40,000 years ago. A cognitive ‘explosion’ was thus attributed to these ‘moderns.’ Unfortunately, because
of lack of evidence for such an ‘explosion’ in other parts of the world, the ‘revolution’ was limited to Europe.
Accordingly, the cognitive gap was filled in with the Eurocentric ‘revolution’ model.
Political correctness, however, conjured up African Eve, and the ‘replacement/out of Africa’ theory was
offered as an explanation for the discontinuity in the fossil and cognitive record (e.g. Mellars 1989). The
hypothesis could also explain the presence of less ‘brutish’ archaic H. sapiens in Africa at a time when robust
archaic hominins – specialized to the climatic extremes of the Ice Age – dominated West Eurasia.
Even after the discovery of the Châtelperronian and other ‘transitional’ industries clearly associated with
Neanderthals (Bednarik 2007 and references therein), the linear paradigm was there to stay. Only the recent
evidence for Neanderthal’s modern cognitive abilities (Rodriguez-Vidal et al. 2014; d’Errico et al. 2017;
Hoffman et al. 2018) have introduced a new approach to Homo sapiens neanderthalensis and have
considered a revision of the linear perception of hominin evolution that was based on presumptions asking
for the existence of a ‘missing link.’
In the light of the latest discoveries, Neanderthals appear to have been our cognitive peers. However, it
would be far-fetched to consider them anatomically-modern. As for their behavior, they were certainly more
aggressive and hierarchical than today’s more gracile and docile hominins (because of various biological
and cultural considerations that will be addressed soon).
Apparently, 40 millennia ago, the Old World was inhabited exclusively by cognitively ‘modern’ archaic
Homo sapiens, at various degrees of robustness. ‘Modern behavior’ would assume a rich diversity during
the ensuing tens of millennia, with its origin in such a generalized ‘last common cultural ancestor.’ I would
suggest that ‘modernity’ – contrary to the consensus view in paleoanthropology – did not arrive suddenly as
an Anatomical–Behavioral–Cognitive package (‘ABC’ of modernity). While cognitive modernity, in my
view, is a biologically-developed species-specific trait, I understand behavior – and, in specific cases, even
anatomy – as culturally-acquired traits.
In this paper, I will focus on two regions, given that one of these (West Eurasia) was considered for long
to be the cradle of cognitively modern humans (CMHs), while the other (southern Africa) is still perceived
as the cradle of anatomically modern humans (AMHs).
I hypothesize that modern behavioral and anatomical traits have developed at different rates and in a
different order. Anatomy appears to be a consequence of cultural behavior in West Eurasia (WE), but it
seems to have been biologically-acquired – and before behavioral modernity – in southern Africa (SA),
where behavior has assumed its modern form as a consequence of anatomy.
From such a perspective, the Eurasian Upper Paleolithic transition cannot be explained as the replacement
of one species with another but rather as a culturally-determined behavioral ‘sudden jump’ (sensu Gould and
Eldredge 1977; Steiner 2017) followed by a more gradual morphological transition (sensu Bednarik 2007)
within the same – and cognitively already modern – species.

Managing the Risks of Cultural Evolution 15
The species-specific ancestral cognitive abilities have also undergone changes during millennia of
biological-cultural coevolution (SA) and, on the other side of the spectrum (WE), during tens of millennia
of cultural-biological coevolution.
SA and WE present very specific biological and cultural evolutionary trajectories which were determined
by very different sets of variables and, consequently, resulted in disparate anatomical and behavioral mani-
festations. That is, cultural behavior seems to have determined anatomical modernity in WE and, conversely,
anatomical changes have determined behavioral modernity in certain SA contexts. Therefore, there can be
no linear continuity between the latter – a Late Pleistocene/Holocene development, 10-12 millennia ago –
and the former – a Middle/Upper Paleolithic occurrence, 60-50 millennia ago. The ‘missing link’ between
biologically-developed cognitive modernity and culturally-acquired behavioral modernity is provided by
exograms.
Consciousness and emergent abilities for external storage of information cannot be separated: I consider
pigment use/engravings and notches/beads and pendants as indexes of biologically-developed consciousness
and cognitive ‘modernity.’ Abstract patterns in paleoart, which dominate at this early stage, are universal.
As for figurative art-like productions (engraved and painted, but mostly the latter), I would suggest that they
already betray culture-specific behavioral traits and, therefore, they can serve only as indices of culturally-
acquired behavioral ‘modernity.’
As all these products of conscious focusing are abundant in the archaeological record, commencing at ap-
proximately 1 million years ago (notches in WE and pigment hoarding in SA; ibid.), and because the type of
consciousness – which is not mere ‘theory of mind’ or self-awareness – that can display such a convergent
mental task is often taken as an index of cognitive modernity (e.g. Gabora 2003), we must conclude that
archaic Homo erectus/antecessor (WE) and ergaster/rhodesiensis (SA) populations – even if only from a
cognitive perspective – were ‘modern.’
If the assumption of such an ancient cognitive modernity seems far-fetched, the undisputable widespread
use of engraving and notching techniques at approximately 0.3 million years ago (not only in WE and SA
but also in East Eurasia; Bednarik 2013) already implies the use of related faculties which, together with
such exogrammatic abilities, are inseparable parts of cognitive modernity. Indeed, the possibility that such
skills – mimetic, lexical, musical – were mastered by Homo rhodesiensis (SA) and heidelbergensis (WE)
becomes accepted and accommodated in the paleoanthropological literature (ibid.; Benozzo and Otte 2017;
d’Errico et al. 2003; Morley 2003).
In order to clarify the apparently paradoxical cultural configurations that I have outlined above, I will
first attempt to expand the currently-accepted definition of exograms as ‘memory traces stored outside the

brain’ (Bednarik 2014b) after which, their relevance to consciousness-as-we-know-it, art and paleoart will
be discussed.
Engrams belong to what is known as (subjective) individual, i.e., autobiographical memory (SGM p. 8).
Engrams are not created to last and their texture can vary from one re-consolidation to the next. Given the
almost unlimited probabilities in the re-sequencing of memory traces stored in various parts of the brain, it
is not surprising that biology and psychology – the disciplines that study autobiographical memory – have
not succeeded capturing engrams in time and locating them in space. The only solution to add detectable
durability to specific configurations that memory traces can assume is, as said above, by adjusting them to
G.F. Steiner
Managing the Risks of Cultural Evolution 17
an objective causality. Objectivity implies an external and agreed-upon rule of sequencing which would
render them accessible to others (sensu Block 1995). Such a ‘rule’ must be accessible itself – learned through
copying or by resorting to communication. In other words, consciously-constructed information packages
that follow a communally agreed-upon objective causality can be fixed and passed on, from one individual
to the other and from one generation to the next. This is precisely the commonly-accepted definition of
collective memory, which is adopted even by a popular online platform like Wikipedia.
Collective memory is already a cultural category and, therefore, culturally-constructed, stabilized and trans-
mitted information packages, unlike engrams, are stored externally, and they are devised to last. While
subjective individual memory relies on short-lived engrams, objective collective memory can be passed on
from one generation to the next with the help of exograms.
Exograms can be defined as memory traces stored outside the brain as consciously-sequenced long-term
information packages meant to stabilize causal calibrations of reality. They belong to the field of cultural
and social sciences, with cognitive archaeology being the discipline dedicated to the study of their origin and
meaning.
These clarifications were necessary in order to answer the question posed above, namely, ‘‘whether en-
grams become re-consolidated each time when specific external stimuli recur, or whether they exist as per-
manently consolidated information packages that can be retrieved in an unaltered form – voluntarily, or in
response to such stimuli?’’ I would thus suggest that engrams re-consolidate on spot, as short-lived subjec-
tive responses to environmental stimuli, whereas exograms are permanently consolidated information pack-
ages that can be retrieved voluntarily, as learned responses to cultural signals. Moreover, the culturally
agreed-upon (objective) causality of exogrammatic representation leaves its imprint on the probable out-
come of individual memory recall and thus, an apparent synchronicity between the two becomes the hallmark
of cultural evolution.
As an accolade, I would like to mention the intricate relationship between collective memory and ‘collec-
tive consciousness,’ with the hope that the explanations above will dispel some of the mystified perceptions
of the latter, as propagated in popular culture. As I will illustrate further on, exograms play a crucial role in
the understanding of these intertwined and often misinterpreted categories.

of information (Bednarik 2014b), proto-language (Bickerton 2009), mimetic skills (Donald 1991), rhythmic
and proto-musical abilities (ibid.; Morley 2003) – can be confidently traced back to approximately 300 thou-
sand years (ka) ago, to archaic Homo sapiens.
At 300 ka, Middle Paleolithic (Middle Stone Age) ‘Mode 3’ industries dominated the cultural landscape,
world-wide (SGM p. 6). Unfortunately, the stories, songs and dances of our Mode 3 past are long-forgotten,
and the paleoanthropologist must thus reconstruct a rich cognitive landscape by relying on a limited number
of surviving scratches incised in durable material.
For reasons that will be touched on soon, Australian Aboriginal cultures have never abandoned Mode 3
industries. Therefore, turning to them in order to understand the origins and meaning of exogrammatic stor-
age is highly rewarding. Likewise, with ritual taking such a central place in Aboriginal life, we may gain
useful insights into its role in cultural transmission.
Like Homo erectus before them, the ancestors of the First Australians were explorers par excellence –
that is, they had ventured to new shores, to environments that were utterly different from those they were
used and adapted to.1 Upon their arrival, the First Australians were equipped with all the cognitive abilities
that paleoanthropologists define as ‘modern.’ Apparently, they had made full use of these capacities: the
land was ‘named,’ and a causal order that was communally-devised in their minds was projected on the
physical environment. Their cultural approach to the new environment was followed by a cognitive and
behavioral adaptation to their own construct of reality. The specific causality of Dreamtime stories was aug-
mented with songs and dances and, most importantly, with portable ‘rock art,’ meant to ‘fix in stone’ the
very causal order (blueprint) of Creation.2
Tjuringas, also known as ‘material mnemonic techniques,’ are typical examples of external memory stor-
age. They tell Dreamtime stories that can be easily ‘read’ by those initiated in exogrammatic skills. The
‘readings’ are communal affairs that are accompanied by ‘non-material mnemonic techniques,’ i.e., music,
dance and song. Every such communal recapitulation of the causal order upon which the environment was
mentally constructed re-consolidates the prescribed sequencing of collective Dreamtime memory traces and
transmits the information to those who participate in a coroboree, or – through meticulous initiation rites –
to the next generation. Ritual rigidity and ‘The Law’ inhibit improvisation and the slightest change in the
sequencing of memory traces is punishable. Reality is kept ‘alive’ thanks to ritual behavior – that is, ritual
re-constructs and re-consolidates the specific sequencing that makes Reality and the information it pertains
accessible to those whose minds are tuned to the same causal ‘wavelength.’
Environmental changes that took place after the first ‘calibration’ of Reality – from meteorite impacts to
desertification and rise in sea level – became added to the initial stories and accommodated to their specific
causality as ‘geomythical sequels’ (Hamacher and Norris 2014). Thus, the body of information that had to
be transmitted increased additively (not to be confused with ‘cumulatively’) and, in order to pass on such a
vast amount of knowledge, ritual behavior became the central component of Australian culture, unlike in
other parts of the world, where cumulative (not ‘additive’) technological innovation became the cultural
preference adopted to address environmental instability (Steiner 2016). Thus, the retention of Mode 3 indus-
tries – with every single tool and technique also embedded in ritual – is rather an index of spiritual sophisti-
cation than of technological backwardness.
In such a context, Cameron’s (2015) question whether Australian ‘rock art’ should be perceived as ‘art
or knowledge,’ becomes pertinent. Moreover, with the starting point of this discussion being abstract (Mode
3) Lower and Middle Paleolithic material – and non-material – mnemonic techniques and, with the emphasis
on ritual transmission, the Australian example might prove instrumental in understanding the role played by
exograms in cultural contexts that can be reconstructed only by relying on archaeologically-preserved trans-
mission techniques, namely: rock ‘art.’

However, this scenario cannot be generalized and applied to the First Americans who, upon their entering the New World,
were at an already Mode 4 technological level and with a long history of cultural specialization behind them.

science of tracking,’ i.e., in mental processes without which elaborate forms of tracking would be inconceiv-
able. Liebenberg differentiates between two ‘scientific’ types of tracking: (a) systematic tracking is restricted
to a step-by-step following of signs, which can be complemented with (b) speculative tracking which, in its
turn, relies on the meticulous gathering of information from signs, until it provides a causally-correct indi-
cation of what the animal was doing and where it was going.
Speculative tracking involves the creation of a working hypothesis based on a causal association of
memory traces related to animal behavior, topography and other tangential phenomena. The emphasis is
primarily on identifying, mentally-sequencing and verbally-debating empirical evidence in the form of tracks
and other signs. In other words, with a knowledge of animal behavior in mind, trackers zoom-in to look for
signs where they expect to find them. They can decide to follow them systematically, or to interpret the signs,
construct a mental model and let the hypothesis guide them to the animal. The ability to predict animal
behavior based on minimal indexical referencing is achieved in a convergent (analytical) mental state. Con-
versely, and complementing ‘scientific tracking,’ following the identification of signs, the hunters do not
waste time to follow the tracks one-by-one, or to debate their meaning at length. They process the minimal
information in a divergent (associative) mental state, in which causal order is not necessarily observed and
proceed immediately running the prey down, based on their ‘intuition.’ During the run, they maintain such
a defocused mental state and enter a trance-like condition in which they become the chased animal and
assume its behavior.
For example, in the last episode of David Attenborough’s BBC documentary The Life of Mammals (2002)
such a ‘persistence hunt’ is followed, at the beginning of which the hunters focus on finding tracks and signs
necessary for a causal prediction of the prey’s movement. During the run, and likely because of the physical
strain involved, the hunters become defocused and continue to run in a trance-like state in which they access
the mind of their quarry and intuitively follow the route taken by the fleeing animal. This is not a sign of
supernatural abilities achieved in an altered state of consciousness, but the result of the simultaneous, non-
analytical processing of memory traces related to animal behavior, which allows the hunter to ‘become’ the
animal – that is, assume its feelings, instincts and behavior. On the other hand, a hypothesis built on empirical
experience and causal reasoning can be verbally debated, and to predict the animal’s ‘thoughts’ and move-
ments does not necessitate a trance-like condition, but only simple causal reasoning based on an intimate
knowledge of animal behavior.
Liebenberg uses interchangeably the terms ‘science’ and ‘art’ of tracking. This is not incidental: system-
atic, i.e., convergent tracking may be designated as a scientific endeavour, while tracking in a trance-like –
that is, in a divergent – mental state is what Liebenberg calls ‘creative science.’ The specific causal outcome
(‘collapse’) of a defocused concept (memory trace) combination achieved in a trance-like condition during
the hunt can become a part of a reciprocally understandable repertoire which, in its turn, can be externally
stored (‘stabilized’) and transmitted as ‘knowledge.’ The experience of the trance is recalled in the ritual
dance that recapitulates the hunt and the insights acquired in a divergent mental state are shared (like meat)
with the community. The mimetic illustration may be accompanied by graphic illustration (not necessarily
painted on rock, despite the ability to do so3) which, in this case, could be a figurative depiction of the hunt,
of a therianthrope, etc.
_________________________

As long as there is demographic strength or cultural stability, transmission may rely only on mimetic/musical transmission.
Children could have drawn hunting scenes in sand during the dances, but the practice of painting them on rock denotes change:
environmental, population bottlenecks, contact with menacing cultures, cognitive losses, etc. I will return to this point toward
the end of the paper.
G.F. Steiner

and therianthropes witnesses to convergent and, respectively, divergent mental processes? Does abstract
rock art sketch causal constructs of reality and do figurative art-like productions illustrate subjective phe-
nomenal experiences? Meanwhile, let us suffice with the observation that both exogrammatic modalities are
meant to transmit/share knowledge acquired in antithetical mental states. The ability for both abstract and
figurative representation must have evolved in parallel with the capacity to shift the contextual focus between
associative and analytical perceptions of reality (sensu Gabora) and with the emergence of the practice to
shift between systematic and trance tracking (sensu Liebenberg).
However, the preference for abstract or figurative exogrammatic representation depends on the im-
portance of the specific type of knowledge that must be transmitted: a conscious formatting of reality became
a necessity when, due to encephalization, an indiscriminate associative combination of memory traces would
have resulted in a combinatorial explosion of possibilities which, in its turn, could have had maladaptive
consequences. When and why did human neural storage capacity become large and complex enough to
accommodate an amount of memory traces that could have resulted in a breakdown of associative pro-
cessing? Answering this question will implicitly determine the date at which convergent thought and thus
an analytical/causal perception of reality became, out of necessity, the most important cognitive signature of
our ancestors.
I have tentatively compared the functionality of Australian Aboriginal material mnemonic techniques to
that of archaeologically preserved Mode 3 rock engravings. My comparison was justified by the similarity
between the motifs depicted and the technological setting within which they were produced. I have also
theorized that the ancestors of Australian Aborigines, very much like Homo erectus before them, had ven-
tured to new environments at a developmental stage when all the cognitive abilities that paleoanthropologists
define as ‘modern’ were in place. Likewise, the biological flexibility of H. erectus – a hominin evolutionary
characteristic that will be introduced and discussed soon – was augmented with their cognitive aptitude for
convergent thought. I argue that biological flexibility enabled Homo erectus to venture out of Africa and that
cognitive flexibility guaranteed their survival and success in novel environments. Very much like the First
Australians, they have presumably ‘created’ a causally-ordered landscape to which they became adapted and
in which they thrived.
According to Liebenberg, the ability to shift at will between the mental states that are employed in per-
sistence hunt can be attributed to Homo erectus. Indeed, the paleoanthropological record seems to support
Liebenberg’s suggestion (Carrier 1984; McCall 2014).
Following Donald (1991), let us consider his suggestion according to which, with the enlarged cranial
capacity of Homo erectus, the human mind became radically different from its ancestral, pre-human condi-
tion. This change is also characterized by a shift from an episodic to a mimetic mode of cognitive function-
ing, made possible by the onset of the capacity for voluntary retrieval of stored memories, independent of
environmental cues. If not environmental, then the cues are, supposedly, cultural. Therefore, the memory
storage should also be cultural, i.e., external and reciprocally understandable. Cultural transmission with H.
erectus must have been beyond simple copying, which would already imply (proto)linguistic abilities. As I
have already suggested, linguistic and musical faculties must be understood as complementary parts of a
much bigger cognitive landscape that also includes mimetic, rhythmical and graphic representational apti-
tudes.
Ian Morley, in his seminal work on the archaeology of music (2003), states confidently that by approxi-
mately 600,000 years ago, with Homo erectus, the vocal and neurological apparatus for voluntary control
over the structure and complexity of vocal utterances was already fully-developed. This enabled extended
and planned sequences of such utterances. Morley attributes a communicative dimension to consciously con-
trolled pitch, contour and intensity. As control increased, the length and complexity of sequences would also
increase. Subsequently, ‘‘the order in which the expressive vocalizations occurred could assume meaning.’’
Here, Morley describes a typical convergent cognitive process and, because his focus is on music – which
we immediately identify as an ‘artistic’ expression – the thin red line that separates art and knowledge be-
comes blurred.

22 Holocene Crossroads
The origin of the cognitive abilities that are the prerequisites of ritual behavior – external storage of
information (Bednarik 2014b), proto-language (Bickerton 2009), mimetic skills (Donald 1991), rhythmic
and proto-musical abilities (ibid.; Morley 2003) – can be thus be traced back to approximately 600 ka ago,
to Homo erectus. Archaic Homo sapiens (including H. heidelbergensis/rhodesiensis) must have already been
in full possession of these faculties and their systematic application can be confidently associated with them.
Based on isolated finds, like the grooves incised on a bovid bone from the Kozarnika Cave in Bulgaria (the
age of which was estimated by Bednarik [2014a] to be >1 million years old), I would suggest that the antiq-
uity of ritual behavior may be pushed back in time to an even earlier age. (Let us not forget that the Kozar-
nika bone [SGM p. 13; Fig. 1] is likely only the visual aspect of a behavior that, as seen above, cannot be
separated from its vocal, mimetic, rhythmic and musical extensions.)
I reserve the right to remain open-minded to an earlier possible origin of ritual behavior: as mentioned in
the introduction, patterns and images drawn, say, in sand or on tree bark have a limited life span. Spirals,
parallel lines or zig-zags traced on such media would have not survived to our days, due to taphonomic and
various weathering processes. Isolated finds may however hint to behaviors that were practiced in contexts
in which stone, bone or wood became the preferred material used for exogrammatic representation. I would
theorize that the practice – and the causal understanding of reality that lies behind it – did not appear sud-
denly, but it gained in importance and assumed increased meaning at around 300 ka ago, which would also
explain the number of finds dated to that period. This might also point to the possibility that it was approxi-
mately at this time when the first individual cognitive trials of a causal understanding of reality became a
well-established collective and trans-generational cultural practice.
Donald (1991) identifies three uniquely human systems of memory representation, namely: (i) mimetic (start-
ing with H. erectus, at c. 1.5 million years ago); (ii) lexical (archaic H. sapiens, 300,000 years ago) and (iii)
external (attributed exclusively to ‘anatomically modern’ humans, at 40,000 years ago). Contrary to the
three-tiered model, I would suggest that the cognitive abilities listed above have developed in synchronicity,
as complementary parts of a complex ritual behavior. Therefore, a single transition is more likely than three
hierarchically distributed cognitive punctuations. Especially so, because the cognitive expressions of the first
and second stages – as theorized by Donald - already include the abilities attributed to the third stage. Mi-
metic, lexical and [graphic] external memory representations are not only complementary to each other but,
because they are the products of the same cognitive process, they do not make any sense when hierarchically
ordered.
In conclusion, symbolling abilities seem to have been present in a latent/emergent form already with
Homo erectus. As Morley argues, H. erectus was in the full possession of the necessary physiological and
neurological apparatus for mimetic, lexical and external memory representation. However, the ability – or
its random use – does not imply its immediate and wide-scale application. The documented systematic ap-
plication of these ancestral abilities – the entire set of what I have labeled ‘ritual behavior,’ of which the
external storage of causally-sequenced memory traces in the form of abstract representations is an integral
component – may be attributed to archaic Homo sapiens (rhodesiensis, heidelbergensis, neanderthalensis)
who, presumably, were also in the possession of latent iconographic abilities that would become fully mo-
bilized only when acquiring meaning and importance in a strictly cultural (i.e., ‘artificial’) environment.
2.4 ‘Consciousness-as-we-know-it’
So far, I have repeatedly referred to a ‘consciously-sequenced’ perception of reality. Moreover, I have
also floated the idea that Lower and Middle Paleolithic abstract representations should be perceived as tan-
gible signs of an emergent species-specific consciousness. At this point, I must address the elusive concept
of ‘consciousness.’ Given the various perceptions and explanations of the concept – which range from the
spiritual to the neuropsychological and quantum-mechanical – there is no clear-cut consensus definition of
G.F. Steiner
Managing the Risks of Cultural Evolution 23
consciousness. From the perspective of what was said up to this point, the best fitting approach to conscious-
ness would be that offered by Ned Block (1995). Block differentiates between phenomenal (P-) and access
(A-) types of conscious perception.
P-consciousness is raw experience of movement, colors, forms, sounds, sensations, emotions and feel-
ings, with our bodies and responses at the center. This is, practically, Einstein’s ‘‘chaotic diversity of our
sense organs,’’ as described in a previous section. It can also be likened to Gabora’s (2003) divergent, un-
focused mental state, the phenomenal awareness of superposed and non-causally related memory traces.
A-consciousness, on the other hand, is information stored in our minds which is made accessible for
verbal report, reasoning, and the control of behavior. Einstein’s ‘‘logically unified system of thought’’ and
Gabora’s convergent mental state – in which loosely related memory traces assume a ‘‘causally-ordered and
reciprocally understandable form’’ – would be the best parallels.
I argue that the ability to shift between Block’s P- and A- aspects of consciousness and between the
divergent and convergent ends of the operational range of Gabora’s contextual focus are closely related
cognitive aptitudes.
The abstract paleoart corpus that has survived from the very period when such abilities emerged are the
material remains of a cultural behavior that must have included additional, non-material cognitive mecha-
nisms of converting individual phenomenal perception to collectively accessible information. As Block
stresses, A-consciousness implies verbal report (i.e., [proto-]linguistic skills), reasoning (that is, a causal
interpretation and perception of not necessarily causally-ordered information and the ability to predict in the
future, based on analytically-devised rules) and controlled behavior (which is determined by and adapted to
the causally-ordered construct of an already predominantly cultural environment).
Miyagawa et al. (2018) approximate a similar process in their ‘cross-modality information transfer hy-
pothesis’ in which, [the extraction of] ‘‘only the essence required for abstract representation instead of com-
puting the entire set of incoming raw [phenomenal] information’’ is the main characteristic of symbolic
thought. Abstract representation and symbolling become thus indispensable in the conversion of phenomenal
conscious perception to accessible information.
Francesco d’Errico and colleagues (2017) propose a comparable cognitive transition in a recent paper
suggestively titled From Number Sense to Number Symbol. In the article, they suggest that a 44 ka old incised
baboon fibula from Border Cave (South Africa) and a similarly notched 72 ka old hyena femur from Les
Pradelles Cave (France) may be interpreted as ‘exosomatic devices’ meant to store numerical information
(SGM p. 13; Fig. 1). Judging by the dates of the artifacts and by similar finds in other parts of the world, the
authors conclude that such exosomatic devices were in use with archaic humans – including Neanderthals –
during the African Middle Stone Age and the European Middle Paleolithic. They interpret the cognitive
background of these devices as ‘cultural exaptations’ which, simplistically formulated, means the application
of a biologically developed cognitive potential in a cultural environment, where the biological ability – or
pre-adaptation, as the term exaptation was previously known – becomes adaptively useful and thus, perpet-
uated in a novel form. However, the ages of these artifacts are much later than those attributed to the already
mentioned and similarly notched/engraved finds from Kozarnika, Wonderwerk or Bilzingsleben and dated
by Bednarik (2014a) to > 1 my, 300 ka and > 325 ka (Fig. 1). Apparently, we can identify two distinct periods
in which abstract notches and engravings had special meaning and importance: (i) the exogrammatic repre-
sentations of archaic hominins from the first period (up to c. 300 ka) may be perceived as the indices of an
emergent consciousness and ritual behavior, while (ii) notches and engravings dated to c. 70 ka and contin-
uing well into the Upper Paleolithic may, indeed, be perceived as expressions of cultural exaptations rooted
in earlier symbolling abilities.
The title of Derek Bickerton’s (2009) book How Man Made Language and How Language Made Man is
just as suggestive as that of the abovementioned paper authored by d’Errico et al. (2017). Block’s A-con-
sciousness implies verbal report and reasoning and, as I have already theorized, proto-linguistic skills must
have been part of ritual behavior together with, or closely related to controlled vocalizations, sensu Morley
(2003). While musical and mimetic abilities would have had a role in the reiteration and trained perception
IFIRARQ 16
24 Holocene Crossroads
of causally-sequenced constructs of reality, the descriptive character of language would have been instru-
mental in the consolidation and transmission of such a conceptually-constructed cultural environment. Not
incidentally, Bickerton stresses on the close relationship between niche construction and the development
of language. I will return to niche construction theory very soon. Meanwhile, I would like to note that the
‘how man made language’ part of the title refers to the process of constructing the cultural niche, while the
‘how language made man’ is a good description of how man adapted to his/her own cultural construct.
Language and time are closely related categories. Bernie Taylor (2017) offers an excellent model for the
origin of our linear perception of cyclical time. Without being aware of it, his approach is complementary to
Bickerton’s proposal regarding the origins of language. Taylor introduces the concept of ‘biological time,’
that is, the meticulous observation of animal behavior, the specifics of which – calving, rutting, mating,
gestation periods – are correlated with seasons, floods, lunar phases and other repetitive (cyclical) natural
phenomena. Lunations become thus indexical references for, say, the availability of food resources. Animal
behavior may vary from season to season and tracking the animal may ask for different strategies during
different lunar phases. Similarly, the meat of certain animals may be rich in fat and nutritious, depending on
the heliacal or nocturnal rising/setting of specific constellations, with the hunt being planned accordingly.
Observing and recording biological time results in an impressive amount of knowledge the transmission of
which, according to Taylor, relies not only on language – sensu Bickerton – but also on rock art. For example,
the famous stag from the Axial Gallery of Lacaux was painted above a row of abstract dots and a rectangle.
The stag is placed above the latter which, in Taylor’s interpretation, points to a specific time of the year –
e.g. the fourteenth (left to right) or second (right to left) lunation (SGM p. 12) – when the stag’s antlers are
at their fully developed stage and, therefore, it possesses the maximum amount of ‘potency’ during its bio-
logical time (see Lewis-Williams 1988; Steiner 2017 regarding the importance of ‘tapping’ power-animal
potency).
Of special interest here is that although the Axial Gallery was painted during the Upper Paleolithic, the
iconic depiction of the stag is accompanied by abstract representations. Therefore, the functionality of the
latter cannot be directly related to the conversion of phenomenal perception to accessible information but
rather interpreted as a later phase of cultural adaptation to an already established construct of reality, an
adaptation of subsistence, social and ritual activities to the biological time of the stag depicted in this specific
mural. Therefore, Taylor’s ‘biological time’ may just as well be called ‘cultural time,’ for reasons which will
become evident in the following sections.
In the paragraphs above, I have illustrated the simultaneous emergence of consciousness and the first in-
stances of exogrammatic expression by drawing parallels between Ned Block’s theory and cognitive phe-
nomena that seem to support the view that the abstract patterns of Lower and Middle Paleolithic rock art
reflect our ancestors’ preoccupation with adapting reality to a culturally-devised conscious format. One of
the main points in the argument is Gabora’s contextual focus hypothesis, which was expanded by Gabora
and Kitto (2013) in order to accommodate a quantum approach to consciousness. When – in the associative
mental state – concepts appear in the context of each other, their meanings change in ways that are non-
compositional, i.e., they behave in ways that violate the rules of classical logic. Gabora and Kitto adopt the
classical Copenhagen interpretation according to which, conscious observation results in quantum state re-
duction. That is, memory traces in an undecided state of superposition become manifested in an ordered and
reciprocally understandable format, according to a communally devised ‘causal stencil.’ The quantum col-
lapse is the result of convergent thought that extracts only the essence required for abstract representation
instead of processing the entire set of memory traces that are open to infinite associative possibilities in a
defocused mental state. The causal stencil is a cultural product which, as I argue, is the general motif of the
oldest, i.e., > 300 ka abstract representations.
Contrary to the popular Copenhagen tradition, Penrose and Hameroff (2011) argue that quantum state
reduction is not the result of conscious observation but, quite the opposite, consciousness is the result of
quantum state reduction. In other words, a specific outcome of the combinatorial probabilities of superposed
G.F. Steiner
Managing the Risks of Cultural Evolution 25
memory traces occurs in synchronicity with – and as a function of – an objective quantum state reduction
(OR).
I am inclined toward considering the classical model, because of its compatibility with my understanding
of the role played by the oldest (> 300 ka) abstract representations, as detailed above. However, the Penrose-
Hameroff hypothesis has the potential to explain the cognitive background of abstract notches and engrav-
ings that I have tentatively ascribed to a later (< 70 ka – 12 ka) period that precedes and then overlaps with
the Upper Paleolithic iconic explosion. I would therefore suggest that the objective causal order to which
our conscious perception of reality adjusts itself – like in the Penrose-Hameroff model – is the very construct
of reality devised by our Lower/Middle Paleolithic ancestors and stabilized during tens of millennia of ritual
behavior. While their abstract notches and geometrical patterns reflect a conscious modelling and calibration
of reality, abstract representations from the second period may be explained as indices of the conscious
conditioning of our behavior, as an adaptation and adjustment to an already externalized – and therefore
objective – cultural construct of reality. Hence, the abstract representations of this period should be ap-
proached from a cultural/behavioral perspective, unlike the first manifestations of exogrammatic abilities,
which reflect a strictly biological/cognitive development.
Simplistically formulated, Lower/Middle Paleolithic exograms illustrate our taming of reality (by its con-
version to a conscious format), while Middle/Upper Paleolithic paleoart mirrors the process of taming our-
selves (by conditioning our behavior to the dictates of our own construct of reality). Art-as-we-know-it would
emerge as a next step, as a technique (sensu Ellul 1964) devised to buffer between biologically-developed
cognition and culturally-acquired behavior.
Fig. 1 - The illustrations above are offered as exemplifications of the suggestion that the biological emergence of a species-
specific type of consciousness could be associated with the first abstract representations of the Lower and Middle Paleolithic
(the Wonderwerk, Bilzingsleben and Kozarnika grooves and engravings). The ability for exogrammatic representation was
apparently an exaptation for the already culturally-conditioned type of consciousness (i.e., ‘consciousness-as-we-know-it’)
that would emerge during the later phases of the Middle Paleolithic (the Border Cave, Les Pradelles, Blombos, Gorham’s Cave
and Kiik-Koba incisions and hashtags) and which would reach its full expression in the iconographic explosion of the Mid-
dle/Upper Paleolithic transition.
Symbol, number, language, time and art, according to anarcho-primitivist philosopher John Zerzan (1999),
are the very cultural constructs that alienate the ‘noble savage’ from his natural environment and which
restrict the full realization of his biological potentials. However, Zerzan’s reification, i.e., the tendency to
take the conceptual as the perceived and to treat concepts as tangible realities, is a cognitive exaptation of
IFIRARQ 16
26 Holocene Crossroads
both ‘savage’ and ‘civilized.’ The only difference between the two is in how their commonly shared cogni-
tive aptitudes were applied and how the inherent risks of cultural evolution were managed.
The Romanian philosopher and writer Lucian Blaga (nominated for the Nobel Prize on the proposal of his
compatriot and admirer, Mircea Eliade) dedicated a whole book to the subject of evolution, part of a trilogy
that promoted historical and cultural theories. In Anthropological Aspects (1976 [1943]) he proposed a ‘new
approach’ to evolution. His insights were only actualized a few decades later, when Steven Jay Gould and
Niels Eldredge (1977) started to consider, independently, questions posed, but only partly answered by
Blaga. I will present below the framework suggested by Blaga and adopt it as a loose frame of reference (not
as a rule, but as a ‘ruler’) that will guide my discussion.
Blaga was looking for a model in which certain particularities, like the problem of what he perceived as
human ‘primitivisms’ could be explained, without recurring to the then widely accepted gradualist and linear
concepts. His ‘new approach’ placed evolution in a field defined by two coordinates within which life be-
came subjected to evolutionary tendencies that took distinct orientations, namely: (i) toward specialized and
optimized organisms, or (ii) toward generalized and autonomous life forms.
G.F. Steiner
Managing the Risks of Cultural Evolution 27
Fig. 2 - The Blaga coordinates (left) augmented with the postulates of the punctuated equilibria hypothesis (right).
- The horizontal phases are the temporal distribution (stasis, duration) of a species, while the vertical ones represent transitional forms.
- The vertically-negative stages are characterized by the permanent adoption of specializations, which result in increased adaptive
rigidity and environmental dependence.
- The closer a species is to the horizontal, the higher the chance of it being ‘captured’ and that no further vertical tendencies would
occur (d2 < d1).
- The vertically-negative phases (u, v) represent ‘sudden jumps’ that become decreasingly shorter in time, the stronger the attraction of
the horizontal (v < u).
- The horizontally-positive phases (a, b, c) become increasingly longer in time (a < b < c).
- The closer a species is to the horizontal coordinate, the weaker the influence of the vertical axis.
- Minimal vertically-positive tendencies may also occur - the closer to the vertical coordinate, the higher the possibility of their transfor-
mation from tendencies to phases. Thus, new lateral evolutionary lines may speciate (h, t).
- The vertical phases are the temporal distribution (stasis, duration) of a species, while the horizontal ones represent transitional forms.
- The horizontally-negative stages are characterized by the permanent adoption of reductions, which result in increased adaptive
flexibility and environmental autonomy.
- The closer a species is to the vertical, the higher the chance of it being ‘captured’ and that no further horizontal tendencies would
occur (d2 < d1).
- The horizontally-negative phases (u, v) represent ‘sudden jumps’ that become decreasingly shorter in time, the stronger the attraction
of the vertical (v < u).
- The vertically-positive phases (a, b, c) become, likewise, decreasingly shorter in time (a > b > c) – apparently, evolution works faster on
the vertical than on the horizontal coordinate.
- The closer a species is to the vertical coordinate, the weaker the influence of the horizontal axis.
- Minimal horizontally-positive tendencies may also occur – the closer to the horizontal coordinate, the higher the possibility of their
transformation from tendencies to phases. Thus, new lateral evolutionary lines may speciate (h, t).
(1) The horizontal evolutionary process, i.e., the strategy of specialization to the environment, occurs mostly
through natural and sexual selection: evolution may be perceived as a success, and a condition that facilitates
survival in a given environment is reached. In other words, from a state of ‘sufficient harmony’ with the
environment, evolution leads to a state of ‘perfect harmony.’ The only problem is that organisms following
this strategy are at peril when the environment they are so highly optimized to changes. The higher the degree
IFIRARQ 16
28 Holocene Crossroads
of specialization, the lower the ability to cope with changes. In cases of extreme specialization, the slightest
fluctuation in the environment can wipe out a species. Another backlash of such an evolutionary mode is
that once a state of ‘perfect harmony’ is reached and, provided that the environment remains stable, further
evolution becomes characterized by the development of hypertrophies.
(2) The vertical mode of evolution is the answer to the dangers inherent in the strategy of specialization: at
the price of conserving some primitive features, a degree of autonomy is also preserved, i.e., a higher flexi-
bility in the face of environmental changes – instead of the smooth specialization through selection, a rougher
evolutionary strategy is adopted, which is transformation through mutations or punctuations. At first
glimpse, this strategy does not seem to be so successful: the organism is not so finely tuned to its environ-
ment. But, when the environment undergoes changes, the flexibility granted by the vertical evolutionary
mode proves its advantage: the higher the degree of autonomy, the lower the danger of being affected by
environmental instability. In cases of very pronounced autonomy, the organism is capable to survive in al-
most any type of natural environment – changes are taken as opportunities, the opening of ‘new horizons.’
In the case of vertical evolution, the tendency is to preserve an already acquired state of ‘sufficient harmony’
without falling in the trap of ‘perfect harmony’ and the dangers entailed in it.
According to Blaga, vertical evolution preserves adaptive flexibility by falling back on a generalized mor-
phology, whereas horizontal evolution results in a specialized morphology that limits adaptive flexibility
and may culminate in the acquisition of maladaptive features.
Blaga approximated a mechanism that in the following decades would become known as the theory of
punctuated equilibria (Gould and Eldredge 1977). The punctuated equilibria model can be applied to both
coordinates and, by doing so, it becomes evident that there is no slowly balanced linear evolution, but only
short, punctuated periods of evolutionary activity – sudden jumps – separated by much longer intervals of
stability – stasis – in which biological changes are practically negligible. Blending Blaga’s ‘new approach’
with the punctuated equilibria model that he has predicted – but fell short of elaborating it – the ‘new ap-
proach’ becomes meaningful even for more recent inquiries regarding the peculiarities of hominin evolution.
In Fig. 2 (right) I have inserted a graphic approximation in which vertical and, respectively, horizontal peri-
ods of stability are interrupted by short-lived transitional phases which, in their turn, are followed again by
stable periods (as detailed in BOX 1).
However, Blaga has drawn a hypothetical ‘biological ceiling’ between the coordinates of his model and thus
he has set a limit to the countless evolutionary possibilities that tend to become realized (Fig. 2, left). As a
function of its proximity to the horizontal, a species’ vertical evolutionary tendencies become narrowed
down, i.e., there is an upper limit of biological flexibility. For example, chimpanzees – as a more specialized
species – display less biological flexibility than bonobos and, similarly, the vertical tendencies of bonobo
evolution (y’) are subject to the constraints imposed by Blaga’s hypothetical evolutionary ‘ceiling.’
Enlarged with the postulates of punctuated equilibria, the graphic model also highlights that the temporal
continuity (stasis) of a species specialized on the horizontal will be increasingly longer, the more optimized
to its environment it is. Over-specialization makes them so rigid that they cannot respond to novel environ-
mental challenges, thus the danger of extinction becomes imminent. On the other hand, the stable phases of
species that stay generalized on the vertical will decrease in time, and their high degree of autonomy would
increase their flexibility in dealing with environmental fluctuations or voluntary changes of habitat, which
could result in a wider geographical distribution.
G.F. Steiner
Managing the Risks of Cultural Evolution 29
ensuing increase in neural storage capacities fits a pattern of delayed maturation characteristic of human
development. The pattern ascribes well to a phenomenon known as neoteny. In Blaga’s days, neoteny was
understood only in a rudimentary and recapitulative way, sensu Haeckel (1883). What Blaga perceived as
‘primitivisms’ must have been the fetal characteristics of juvenile apes that became stabilized features in
humans.
Steven Jay Gould, in his Ontogeny and Phylogeny (1982), offers a list of these primitive-juvenile – that
is, neotenous – features: our ‘flat-faced’ orthognathy/reduction or lack of body hair/loss of pigmentation in
skin, eyes and hair/the shape of the external ear/the epicanthic fold/high relative brain weight /the central
position of the foramen magnum/persistence of the cranial sutures to an advanced age/the structure of the
hand and foot/the form of the pelvis/the labia majora of women/the ventrally-directed position of the sexual
canal in women/certain variations of the tooth row and cranial sutures/absence of brow ridges and cranial
crests/thinness of skull bones/position of orbits under cranial cavity/brachycephaly/small teeth and late erup-
tion of teeth/no rotation of the big toe/prolonged period of infantile dependency and of growth/long life span.
According to Gould, evolution occurs when ontogeny is altered in one of two ways: 1) when new features
are introduced at any stage of development with varying effects upon subsequent stages, or 2) when features
already present undergo changes in developmental timing. Together, these two processes exhaust the formal
content of phyletic change; the second process is heterochrony.
Neoteny is only one of the six possibilities of heterochrony (change in developmental timing): (i-ii) accel-
eration (faster) vs. neoteny (slower); (iii-iv) hypermorphosis (further) vs. progenesis (not as far); (v-vi) pre-
displacement (begins earlier) vs. postdisplacement (begins later) (Bogin 1999).
Ashley-Montagu (1989) theorized that part of the differences seen in the morphology of modern types of
man can be attributed to different rates of ‘neotenous mutations’ in their early populations. Thus, the Mon-
goloid skull is the most neotenized human skull. The European skull is less neotenized than the Mongoloid
and African, with the Australian Aboriginal skull still less neotenized than the European, with the Neander-
thal skull even less neotenized than that of the Australian Aboriginal. Observing the San, he described the
following neotenous traits relative to Europeans: large brain/light skin pigment/less hairy/round-
headed/bulging forehead/small cranial sinuses/flat roof of the nose/small face/small mastoid processes/wide
eye separation/median eye fold/short stature. In addition, McKinney and McNamara (1991) attracted atten-
tion to the fact that African Pygmy and Asian Negrito populations also display highly neotenous features.
However, as Hulse (1962) noticed, neoteny is not the only dimension of heterochrony that plays a role in
human evolution. He brings up the example of Australian Aboriginals, who have retained similar skeletal
characteristics to those which most people possessed in earlier times (gerontomorphic characteristics, as
opposed to the pedomorphic traits that the Kalahari Bushmen display).
Understanding neoteny in this larger context, Thiessen (1997) argues that Homo sapiens is more ne-
otenized than Homo erectus, and Homo erectus more than Australopithecus. By the same token, bonobos
display more neotenous features than chimpanzees (ibid.; de Waal and Lanting 1997). Moreover, Ashley-
Montagu (1989) suggests that juvenile pithecanthropine and australopithecine skulls would have had a closer
resemblance to those of modern humans than to those of the adult forms of their own species. Humans, in
their turn, have more neotenous skulls than Homo erectus and archaic H. sapiens.
The persistence of ‘primitive’ features, sensu Blaga, may thus be explained with the phenomenon of neoteny.
Therefore, his generalized (vertical) mode of evolution stresses the role played by neotenous processes in
human development, in which it assumes a crucial function in inhibiting tendencies toward specialization.
Neoteny, however, must not be understood as a process that manifests itself exclusively in morphology.
The cognitive implications resulting from the retention of a juvenile shaped cranium and brain volume ratio
to the body are equally far-reaching and of central importance to my inquiry. On one hand – within the Blaga
coordinates – life escapes the attraction of the horizontal, which would restrict its potentials, but the price of
this autonomy is high. The pedomorphic ape that is the result of such an evolutionary mode is extremely
IFIRARQ 16
30 Holocene Crossroads
vulnerable. But, on the other hand, the means to compensate for such an unspecialized morphology is ‘of-
fered’ by neoteny itself. As Bruce Charlton argues (2006), what looks like immaturity – or, in his terms, the
retention of youthful attitudes and behaviors into later adulthood – is, actually, a valuable developmental
characteristic, which he calls psychological neoteny. Highly educated people and eminent scientists demon-
strate more neotenous psychological traits. The same applies to ‘natural people’ and children. In fact, the
ability of an adult human to learn is considered a neotenous trait. Biological neoteny in humans had as a
side-effect psychologically neotenous traits: curiosity, playfulness, affection, sociability, and an innate desire
to cooperate (ibid.).
Psychologist David Bjorklund (1997) writes that “in many cases, important evolutionary changes are
brought about by retardation of development, not by acceleration. This is reflected by the concept of neoteny,
which means literally ‘holding youth,’ or the retention of embryonic or juvenile characteristics by a retarda-
tion of development.” Gould (1982) also highlights “the undeniable role of retardation in human evolution”
and he considers human neoteny as an “evolution by retardation”.
Such juvenile traits were insightfully understood by psychoanalyst Donald Winnicott (1971) in revealing
how playing, for instance, assumes a decisive role in the mental growth of children and, no less, in human
coping with reality and in developing our culture, sciences, philosophy, and arts.
Following Gould, Jules Bemporad (1991) writes that “we may be considered slowly developing apes
whose prolonged infancy allows us to internalize and develop a much more complex behavioral and cogni-
tive repertoire and who persist in displaying juvenile features well into adult life.” Playfulness is striking
among these juvenile features, and although playing is ascribable to all mammalian brains, as neuroscientist
Jaac Panksepp (1998) mentions, “humankind is still an especially playful species possibly because we are
neotenous creatures who benefit from a much longer childhood than other species.” Furthermore, he writes
that “play is an index of youthful health. The period of childhood has been greatly extended in humans and
other great apes compared with other mammals, perhaps through genetic regulatory influences that have
promoted ‘playful’ neoteny.” By the same token, discussing neoteny, Bjorklund (1997) remarks that there
is no other species that demonstrates curiosity and play into adulthood to the extent that Homo sapiens do.
Novelty and the unknown are typically avoided in adult animals, with the notable exception of humans.
However, and as it will be discussed soon, certain phenomena that closely resemble genuine biological
and psychological neoteny would mutate to new dimensions in strictly cultural contexts, as pseudo-neote-
nous maladaptive processes.
I would like to conclude this section with the observation that unlike Blaga’s horizontal coordinate –
which is an evolutionary blind alley leading to inevitable extinction – the vertical mode of evolution does
not imply that, upon reaching a high position on the o-y coordinate, tendencies toward specialization would
cease to exert their attraction. At around the time of the Middle/Upper Paleolithic transition, another ‘sudden
jump’ seems to have occurred, catapulting our ancestors into a new evolutionary dimension which, in its
turn, became defined by similar tendencies toward specialization or autonomy.

thousands of years. The Neolithic was very short when compared to the preceding stages – it commenced
approximately 10 ka ago in the Levant, slightly later in other areas, and it lasted for some 6 ka, followed by
the Chalcolithic – 1 ka, which was itself followed by the Early, Middle and Late Bronze Age (1 ka together)
and the Iron Age, which lasted for only 600 years. However, the Neolithic and the cultures following it do
not belong to the biological field, and they are only mentioned here to illustrate the amazing rate assumed
by cultural change. From 1 million to 800 thousand, to 70 thousand, to 25 thousand – at the dawn of history
the life span of cultures is expressed in thousands, later on in hundreds and, in modern and contemporary
times, in only decades, or years.
From this brief inventory, it becomes evident that the life-span of industries and cultures decreases in
time - they are stable for progressively shorter periods and they accompany specific evolutionary stages
(stases) together with the transitions (sudden jumps) to another. Only subsequent evolutionary stages (spe-
cies) develop novel technocomplexes.
By comparing ‘stones and bones,’ one can notice that in the biological field defined by the o-x/o-y coor-
dinates, the rate of cultural change lags behind that of biological speciation. Or, to put it simplistically, old
bones use old stones (H. erectus paired with the Acheulian); transitional bones keep the old stones (H. hei-
delbergensis still associated with the Acheulian); new bones use new stones (H. neanderthalensis paired with
the Mousterian). The emergence of novel technologies could be explained with the inventiveness that, as
seen, is a psychological side-effect of neoteny – new bones display neotenous traits when compared to old
bones.
The ‘rule’ is observed up to a point, at which culture takes the lead, and biology starts lagging behind it.
Such a switch was common to all human populations (cf. Zerzan 1999) with the difference that in West
Eurasia it had occurred in a quite precipitated fashion, due to environmental stress. In southern Africa, on
the other hand, it was more gradual and its impact less severe. In both areas, however, culture would be a
step ahead of biology until the Mesolithic, when technological development had reached a ‘sufficient’ state
of elaboration. (In Australia, for reasons that were already mentioned, Mode 3 industries persisted, and the
switch was not of a technological nature but, nonetheless, the ancestors of Aboriginal Australians had also
effectuated it.)
In West Eurasia, the date at which the rate of biological evolution was overtaken by that of cultural change
can be confidently placed within the Middle/Upper Paleolithic transition. Undoubtedly, the period witnesses
a ‘new beginning,’ the onset of strictly cultural rules that would determine the nature of further (anatomical
and behavioral) evolution. The ‘suddenness’ of the Upper Paleolithic transition and the empirical evidence
that for the last 40 millennia – or more – culture evolves at a speed that biology cannot catch up with, led to
the assumption that in Europe, where the transition was studied in depth, the aboriginal population was
displaced by newcomers who brought with them – or improvised on spot – a ‘superior’ culture. The Mous-
terian tradition of the Neanderthals, according to the ‘rule,’ should have also been the culture of transitional
forms leading to anatomically modern humans (AMHs); when finally, Homo sapiens sapiens appeared in
the fossil record, he – and he alone – was supposed to develop the Aurignacian.
However, as already mentioned in the introduction, there were no transitional fossils to be unearthed,
except the so-called ‘Neanderthaloids’ who were not confined to a clear-cut period and, because of their
archaic features, their ages were grossly exaggerated. Moreover, some finds that had clearly developed from
the region’s final Mousterian, but also showed Aurignacian characteristics were discovered all over Europe
(Malez 1959; Svoboda 1993; Kuhn and Stiner 2001). But, given the misconception that the Neanderthals
were brutish cavemen, the ‘big bang’ in our cognitive evolution could not be attributed to such a backward
species.
Robert Bednarik (2007) has followed the changes seen in human skeletal characteristics and has corre-
lated them with the complex mosaic of the European tool traditions from 45 to 30 ka ago. He has attracted
attention to the fact that the fossil record does not yield unanimously ‘anatomically-modern’ remains, and
that archaic-looking – and likely archaically-behaving – ’Neanderthaloids’ dominate the European theater
of evolution until relatively recent times, without any trace of a sudden ‘anatomically-modern’ intrusion.
The changes in human skeletal characteristics, according to Bednarik, were gradual. However, the cultural
IFIRARQ 16
32 Holocene Crossroads
changes were remarkable, and they seem to have developed at a rate that was markedly faster than that of
biological changes. ‘Neanderthaloids’ gave gradually way to AMHs – and were not suddenly displaced by
them – long after the Aurignacian.
Bednarik (ibid.) also emphasizes that the accelerated rate of cultural change – unlike in previous periods,
when ‘the rule’ was still observed – occurred in a period when only archaic hominins were present in Europe.
He thus suggests that not only the Aurignacian-proper, but also the Bohunician, the Szeletian, the Olschew-
ian, the Jankovichian, the Bachokirian, the Uluzzian, the Uluzzo-Aurignacian, the Proto-Aurignacian and
the Altmühlian might all relate to humans other than the so-called ‘moderns.’ Moreover, he concludes that
the ethnicity of the makers of any stone tool tradition and exogrammatic representation of the entire first half
of the Upper Paleolithic – including the entire Aurignacian – appears to be that of robust, Neanderthal-like
humans, or of their direct descendants. Bednarik concurs here with Tobias (1995), according to whom, the
search for physical modernity is itself misguided, as modernity is indicated by cognition, behavior and cul-
ture, and not by cranial architecture or other minor physical differences.
At approximately 50 to 40 thousand years ago, a cognitively modern indigenous population, perfectly
capable to accomplish the Upper Paleolithic ‘revolution’ by itself was already present in Europe. Therefore,
and as I have already postulated, the Neanderthal to AMH transition should not be interpreted as the replace-
ment of one species with another, but as a culturally-determined behavioral ‘sudden jump’ followed by a
gradual morphological transition within the same – and cognitively already ‘modern’ – species.
Additional, but already culture-specific cognitive changes have followed the behavioral punctuation and
have accompanied the morphological transition. Their emergence can be attributed to the period in which
the rate of cultural change accelerated to such an extent that biological evolution was left lagging behind it
(SGM p. 15).
I would define this crucial moment in our cultural evolution ‘the Upper Paleolithic singularity.’ At around
the time of the Middle/Upper Paleolithic transition, the above-mentioned behavioral punctuation had cata-
pulted our ancestors into a new evolutionary dimension which, in its turn, became defined by tendencies
toward specialization or autonomy, very much like Blaga’s biological theater of evolution.

Blaga coordinates must not be understood as a continuation of the biological verti-

The coordinates of the cultural field (Fig. 4, below) start from a hypothetical point (o’) that represents an
idealized stage that was – theoretically – supposed to have been reached on the vertical coordinate of the
biological field, at the time of the Eurasian Middle/Upper Paleolithic transition. A perpendicular line that
illustrates tendencies toward cultural specialization splits off to the right (o’-x’), and a vertical coordinate
(o’-y) – which is a continuation of the biological vertical – follows cultural tendencies toward flexibility and
generalization.
The idealized coordinates run from the tentative date mentioned above (o’) to the present (x’/y). At this
stage, the chronological frame is arbitrary, but it will gradually become evident why the Middle/Upper
Paleolithic transition is not the factual starting point of the divergence between cumulative and reductive
cultural orientations, but only the beginning of horizontal cultural tendencies. The meanings behind the spec-
ifications marked along and inside the coordinates – cumulative vs. reductive cultural orientations/biological
neoteny vs. cultural gracilization/culturally- vs. biologically-acquired behavioral modernity/ratcheting- vs.

4. Cultural Sufficiency/Efficiency
In biology, niche construction is the process in which an organism alters its own – or other species’ – envi-
ronment, often but not always, in a manner that increases its chances of survival. Changes that organisms
bring about in their worlds that are of no evolutionary or ecological consequence are not examples of niche
construction (Odling-Smee et al. 1997).
Several biologists have argued that niche construction is as important in evolution as natural selection
(for a detailed discussion, see Yeoman 2011). Not only does an environment cause changes in species
through selection, but species also cause changes in their environment through niche construction This back-
and-forth creates a feedback relationship between natural selection and niche construction: when organisms
affect their environment, that change can then cause a shift in what traits are being naturally selected for.
NCT has far-reaching implications for the human behavioral ecology. Standard evolutionary theory only
allows for cultural processes to affect genetic evolution by influencing the individual and depends on the
ability of that individual to survive and pass on its genes to the next generation. Cultural processes are viewed
merely as an aspect of the human phenotype and are not believed to be consequential to human evolution.
Cultural diversity is believed to reflect variation in the environments that different populations of humans
evolved in, and nothing else. This theory overlooks the fact that humans can modify their selective environ-
ments through cultural activity, thus feeding back to affect selection (Odling-Smee 2003).
Certain cultural environments have completely eliminated the natural component and, in such an artificial
context, selecting for maladaptive traits that only benefit survival in the specific cultural environment – but
affect negatively biological fitness – becomes the driving force of ‘cultural evolution.’ According to Odling-
Smee (ibid.), cultural processes add a second knowledge inheritance system to the evolutionary process
through which socially-learned information is accrued, stored, and transmitted between individuals both
within and between generations. With the addition of language to human culture came an increased mental
capacity. Or, following an increased mental capacity, language was added to human culture – I have already
mentioned this problematic sequence in one of the preceding sections. This allowed for human adaptation to
the cultural niche to be a learned process, unlike for non-human species, whose adaptive process to the
natural environment is instinctual. The result was a marked acceleration of environmental, behavioral and
G.F. Steiner

genetic modifications. As niche construction advocate Derek Bickerton (2009) argues, ‘‘humans could con-
struct their niches without having to wait on interminable rounds of feedback between genes and behavior.’’
The speed at which humans are able to construct niches modifies the selection pressures and either genetic
evolution or further niche construction can result (Odling-Smee 2003).
IFIRARQ 16

groups is needed to ensure sufficient innovation to compensate for a constant drain due to errors in transmit-
ting knowledge and skills. When group size becomes too small, the rate of loss will outstrip replication and
innovation. The result is flawed transmission and failure to outrun the treadmill. This can lead to maladaptive
losses and depletion of technologies, compromising a society’s evolutionary prospects.
Joe Henrich (2004) attempts to explain a major ‘puzzle’ in anthropology with the help of his treadmill
model, namely: the apparent social ‘devolution’ of Tasmanian Aboriginals during the Holocene. On the face
of it, the Tasmanian case study appears to be ideal for testing Henrich’s model, because (i) the size of the
potential group of imitators likely dropped substantially when Tasmania became isolated from mainland
Australia, whereas (ii) their tool assemblage appears to have decreased in complexity. This was believed to
be indicated by the disappearance of the bone points used to make clothing before the rise in sea level around
8,000 years before present – when the ancestors of Tasmanians became isolated – and, that at the time of
contact with Europeans, the Tasmanians were not wearing clothing, despite experiencing a cold and wet
climate (a number of convincing counterarguments to Henrich’s use of the Tasmanian ‘case’ for the illus-
tration of his ‘treadmill model’ were listed by Andersson and Read [2006])
However, there is a wider conceptual and empirical problem hiding here. The strong focus on technology in
cultural evolution research clearly stems from the fact that technological skills can be tracked archaeologi-
cally. But what if groups with low technological complexity invest their inventiveness in developing complex
non-technological skills?
Taylor (2010) makes the case that cultures can be expected to pursue either of two trajectories with respect
to investment in material technology. The first is the one that we tend to expect, where the functioning of the
body is augmented by complex material technology. Reliance on material technology, however, also has the
effect of entangling individuals in various requirements, such as obtaining and transporting raw material,
maintaining and repairing artifacts, and dealing with the risk of technology failing (Hodder 2012). This
indicates that, under certain circumstances, it might be more beneficial to go in a direction that minimizes
the dependence on material technology, replacing it with non-material skills instead. Taylor argues that the
Tasmanians, with their simple tools, show clear evidence of having pursued such a trajectory in their devel-
opment of cultural strategies for dealing with their environments. This would mean that their low technolog-
ical complexity says little about the complexity of the skills they maintained in general.
Apparently, the cultural evolution of the Tasmanians was based not on accumulation and ratcheting of
innovations for innovations’ sake, but on reduction and flexibility. Moreover, although there is no culture
that does not build its own niche, the cultural niche of the Tasmanians and of other small and isolated soci-
eties that can be described as ‘reductionist’ (sensu Woodburn 1982; Taylor 2010; Steiner 2017), was proba-
bly not too elaborate. Despite isolation, at the arrival of the Europeans the Tasmanians were healthy, well-
fed and thriving, albeit in small numbers. Unfortunately, by the time that modern anthropology took an
interest in describing such a peculiar mode of cultural evolution, the Tasmanians were already acculturated
and on the brink of extinction. Therefore, no model of ‘reductive’ cultural evolution can be hypothesized in
the Tasmanian case, but neither one of cultural loss, in lack of reliable ethnographic data.
The Andamanese are also brought up by Henrich (2004) as another example of an isolated group prone
to cultural loss. His equations suggest that the indexes that quantify loss in the treadmill model are lower in
the case of the Andamanese than those observed with the Tasmanians. Henrich explains this result by as-
suming that – unlike the Tasmanians – the Andamanese were contacted and, therefore, not utterly isolated.
He enrolls genetic evidence in support of this suggestion. Firstly, the genetics that he cites are not more
convincing than that referred to by those who strive to prove the opposite, i.e., an extended – and in excess
of a ‘mere’ 8,000 years – period of isolation of the Andamanese (Thangaraj and Hagelberg 2003). Secondly,
only because the Andamanese were ‘known’ to the outside world does not automatically imply that there
was contact.
The Jarawa and Sentinelese of the Andaman Islands were never studied in a scientific manner, but one
may risk theorizing – by inferring data collected about the related Onge of Little Andaman and the Batek
Negritos of Malaysia – that they could be hunters and gatherers of the egalitarian immediate-return type.
G.F. Steiner

Moreover, intentional avoidance of formal long-term binding commitments, relational autonomy in personal
affairs, and reverse dominance hierarchy are integral parts of an IR context (Dale et al. 2004). That is,
commitments, debts, and assertiveness are discouraged. Distributed decision-making and communal ritual
are both part of the egalitarian character of these societies.
IFIRARQ 16
38 Holocene Crossroads
Cultural flexibility was also researched, with the surprising conclusion that religious manifestations are
far from being rigid and orthodox, but very fluid and accommodating in character (Dowson 1994; Chidester
et al. 1997; Low 2004).
A benign view of nature is dominant, hence the trust in its providing capacities. Paradoxically, IR societies
are isolated in harsh peripheries like deserts, draught-prone savannas, and impenetrable rainforests. How-
ever, they are all characterized by their infinite trust in the providing capacities of such inhospitable envi-
ronments and have a philosophy of under-exploiting resources (Sahlins 1972). Conversely, DR groups live
in more generous environments, but doubt nature’s providing capacities and tend to overexploit resources
and supplement them by recurring to storage (Dale et al. 2004 and references therein).
Apparently, IR hunters and gatherers may be described as pursuing a reductive cultural evolution, which
is in sharp contrast with the standards of cumulative cultural evolution modeled by DIT theoreticians.
Another caveat in DIT and NCT is that the takeoff of both cumulative cultural evolution and the con-
struction of the cultural niche within which the ‘evolution of cultural evolution’ (Henrich and McElreath
2003) takes place is forcibly dated to the alleged Upper Paleolithic ‘big bang’ in cognitive modernity (e.g.
Mithen 1998). Hence, perceiving IR economy as a primordial state – which, to an extent, it is – and the
egalitarian societies that pursue it as living fossils – which, they are definitely not – would practically deny
their being cognitively and behaviorally modern humans. In the following sections I will argue that, although
IR subsistence strategies are cultural ‘primitivisms,’ their adoption denotes a high degree of evolutionary
flexibility and that the egalitarian societies developed by those who have returned to IR economies are cul-
tural ‘achievements’ which, unfortunately, are utterly ignored in the analytical models of DIT.
5. Cultural Heterochrony
Let us not forget that neoteny is only one of the six possibilities of heterochrony, or the change in the timing
of biological developmental events (Bogin 1999). Acceleration (faster) is the opposite of neoteny (slower),
hypermorphosis (further) is the converse side of progenesis (not as far), and predisplacement (begins earlier)
is the complementary aspect of postdisplacement (begins later). The pace of developmental change in culture
may assume all these possibilities and, as it will soon become evident, acceleration, predisplacement and
hypermorphosis define cumulative (horizontal) cultural evolution, while neoteny (slowing down), progenesis
and postdisplacement are the main characteristics of reductive (vertical) cultural evolution.
However, these terms assume a relativistic meaning in culture, the inevitable consequence of which is
our biased perception of what is ‘primitive,’ when compared to our understanding of what it means to be
‘civilized.’ In order to understand the intricacies of cultural heterochrony, I will follow cultural ratcheting
G.F. Steiner
Managing the Risks of Cultural Evolution 39
techniques described by DIT theoreticians (e.g. Tomasello 1999) in parallel with – and contrasted to – lev-
eling mechanisms, as observed by anthropologists (e.g. Woodburn 1982). The importance of demographic
strength in cultural transmission will also be questioned and alternative strategies meant to cope with the
threat of the ‘treadmill effect’ (Henrich 2004) will be forwarded.

The article raises a number of hypothetical possibilities that are quite contradictory to the orthodox per-
ception of the turbulent Middle to Upper Paleolithic transition. The existence of ‘social memory units’ and
their characteristics, as suggested by Richter, already set European cultural developments that occurred 60
millennia ago within a theoretical framework that is very much like that approached in dual inheritance
theory. In this thought-provoking paper, Richter places late Neanderthals in a cultural context that was sup-
posed to have commenced only with ‘anatomically modern humans’: cumulative cultural evolution.
– Content bias results from situations where some aspect of a cultural variant’s content makes them more
likely to be adopted (McElreath and Henrich 2007). Content biases can result from genetic preferences,
preferences determined by existing cultural traits, or a combination of the two.
– Context bias results from individuals using clues about the social structure of their population to determine
what cultural variants to adopt. The determination is made without reference to the content of the variant.
There are two major categories of context biases: (i) model-based biases, and (ii) frequency-dependent biases
(ibid.).
(i) Model-based biases result when an individual is biased to choose a particular ‘cultural model’ to imitate.
There are four major categories of model-based biases:
(1) prestige bias,
(2) skill bias,
(3) success bias,
(4) similarity bias
(1) A ‘prestige bias’ results when individuals are more likely to imitate cultural models that are seen as
having more prestige. A measure of prestige could be the amount of deference shown to a potential cultural
model by other individuals. (2) A ‘skill bias’ results when individuals can directly observe different cultural
models performing a learned skill and are more likely to imitate cultural models that perform better at the
specific skill. (3) A ‘success bias’ results from individuals preferentially imitating cultural models that they
determine are most generally successful (as opposed to successful at a specific skill as in the skill bias). (4)
A ‘similarity bias’ results when individuals are more likely to imitate cultural models that are perceived as
being similar to the individual based on specific traits.
(ii) Frequency-dependent biases result when an individual is biased to choose particular cultural variants
based on their perceived frequency in the population. The most explored frequency-dependent bias is the (1)
‘conformity bias.’ This results when individuals attempt to copy the mean or accepted cultural variant in the
population. Another possible frequency dependent bias is the (2) ‘rarity bias.’ This bias results when indi-
viduals preferentially choose cultural variants that are less common in the population. The rarity bias is also
called a ‘non-conformist’ or ‘anti-conformist’ bias (Henrich and McElreath 2003).
– Social learning is the other cornerstone of cultural transmission which, at its simplest, involves blind cop-
ying of behaviors from a model (someone observed behaving). Although learning is a more advanced form
of social transmission, the same potential biases apply to both:
(1) success bias (copying or learning more effectively from those who are perceived to be better off),
G.F. Steiner
Managing the Risks of Cultural Evolution 41
(2) status bias (copying or preferentially learning from those with higher status),
(3) homophily (copying/learning from those most like ourselves),
(4) conformist bias (disproportionately picking up behaviors that more people are performing) (ibid.).
– Social networking (even in its incipient phase, as described by Richter [2000]) must have reflected the
biases listed above – prestige, skill and status can be increased through the talent for technological innovation
and, in a scenario in which ‘technology for the sake of technology’ is pursued (see Taylor 2010), technolog-
ical acquisition becomes an important driving force. Exchange, in this case – and beside its role in developing
social networks – becomes another modality in the consolidation of prestige. Barter and/or trade were likely
the by-products of status-related biases and must have played a role in the ratcheting of technological inno-
vation by taking it to a ‘more than sufficient’ level.
Leveling mechanisms (which slow down and stabilize the pace of cultural evolution) are the counterpart of
ratcheting techniques (which accelerate the pace of cumulative cultural evolution). Therefore, in the cultural
field (see BOX 2), leveling mechanisms assume the role played by neoteny in the biological field (BOX 1) and
they can thus be understood as an expression of cultural neoteny. Moreover, group selection – a function of
the strength of conformist biases in cumulative cultural evolution – does not seem to play a role in reductive
contexts, because of the stress on non-conformist biases. As it will soon become self-evident, hypermorpho-
sis/progenesis and predisplacement/postdisplacement – the other aspects of heterochrony beside acceler-
ated/slowed down – do also have cultural extensions.
But first, let us take a closer look at how do leveling mechanisms act and – in the next section – at when did
they commence to define the trajectory of vertical cultural orientations?4
As James Woodburn explains (1982), ‘‘societies, which have economies based on immediate- rather than
delayed-return, are assertively egalitarian. Equality is achieved through direct, individual access to re-
sources; through direct, individual access to means of coercion and means of mobility which limit the impo-
sition of control; through procedures which prevent saving and accumulation and impose sharing; through
mechanisms which allow goods to circulate without making people dependent upon one another. People are
systematically disengaged from property and therefore from the potentiality in property for creating depend-
ency.’’
The characteristics of these immediate-return systems were already mentioned in some detail, and there-
fore, I will only present the essence of Woodburn’s observations on how these societies promote equality.
The social organization of all the studied immediate-return hunter and gatherer societies has the following
basic characteristics: (1) Social groupings are flexible and constantly changing in composition; (2) Individ-
uals have a choice of whom they associate with in residence, in the food quest, in trade and exchange, in
ritual contexts; (3) People are not dependent on specific other people for access to basic requirements; (4)

Having in mind cultural heterochrony, I can already say – without being a spoiler – that cultural evolution did not assume a
vertical tendency 60 ka BP – the date to which Richter pushes back the onset of cumulative cultural evolution. The cultural
strategies elaborated by H. sapiens neanderthalensis were a predisplacement, a cultural punctuation effectuated at a behavior-
ally still aggressive and markedly hierarchical stage that had paved the way to cultural hypermorphosis.
IFIRARQ 16
42 Holocene Crossroads
Relationships between people - whether relationships of kinship or other - stress sharing and mutuality but
do not involve long-term binding commitments and dependencies of the sort that are so familiar in delayed-
return systems. What is perhaps the most remarkable characteristic is that these societies systematically elim-
inate distinctions of wealth, of power and of status.
Woodburn recognizes the need to explore the expression of egalitarianism in religious belief and practice,
and he apologizes for not doing so. However, Lewis-Williams (1988) and Dowson (1994) did just that – their
conclusions will be presented and discussed in the next sections.
As for now, there is more than sufficient anthropological evidence upon which the suggestion that with
immediate-return hunters and gatherers rigorous and systematically-applied techniques – i.e., leveling mech-
anisms – which inhibit a cumulative development based on the material, social, and even spiritual compo-
nents of culture apply. Moreover, any tendency toward hierarchy is also discouraged, given the immediate
effect of these stabilizing mechanisms, namely: the ability of individuals to attach and to detach themselves
at will from groupings and from relationships, to resist the imposition of authority by force, to use resources
freely without reference to other people, to share as equals in meat brought into camp, to obtain personal
possessions without entering into dependent relationships.
What these cultural ‘values’ achieve, is to disengage people from property, and from the potentiality in
property-rights for creating dependency. Therefore, the social component of culture is also displaying a high
degree of flexibility, without being elaborated at the expense of other cultural components. As for the mental
and spiritual dimensions of culture, I will soon touch on the former and elaborate on the latter and conclude
that a similar degree of flexibility is in place.
Woodburn thinks that such a cultural achievement can only be realized – without impoverishment – in
societies with a simple hunting and gathering economy because, under different circumstances, such a degree
of disengagement from property would inevitably damage the operation of the economy. In the specific
immediate-return context, the fluidity of local grouping and spatial mobility, combined with and reinforced
by a set of distinctive egalitarian practices that discourage people from accumulation, inhibit not only polit-
ical change but also any form of economical intensification. Therefore, ‘immediate-return,’ albeit a cultural
‘primitivism,’ should rather be perceived as a flexible – and thus unspecialized – cultural base that allows
for the development of the aforementioned egalitarian principles, which are a cultural accomplishment.
The question that arises is, whether such a basic economy is an ‘inheritance’ from the past, or a ‘reduction’
from a more elaborate ‘delayed-return’ stage? While ‘immediate-return’ subsistence strategies are, indeed,
cultural ‘primitivism,’ egalitarian societies are cultural successes. The evidence presented in the next part of
the paper will not only conclusively answer this important question, but it will also tangibly illustrate the
concept of ‘cultural neoteny.’ Dual inheritance theory models perfectly the cumulative aspect of cultural
evolution with non-egalitarian societies and it omits – or dismisses – the achievements of immediate-return
hunters and gatherers. In contexts in which the development of social complexity is consciously inhibited
and is not of central importance in cultural transmission, terms like ‘treadmill effect’ and ‘ratcheting effect’
also lose their meaning.
G.F. Steiner
Managing the Risks of Cultural Evolution 43
Gene-culture coevolution (DIT) predicts that, under certain situations, cultural evolution may select for
traits that are genetically maladaptive (Boyd and Richerson 1985). When the cultural environment changes
with an increased frequency – as it does for the last 60 millennia – biological adaptations cannot catch up,
except by shortcuts that may result in biologically maladaptive, but culturally fit characteristics.
From a strictly biological point of view, neoteny should have continued to dictate further cranial growth,
the lack of which is striking, given that apparently neotenous features became accentuated during the last
tens of millennia of cultural evolution. However, in a cumulative cultural environment, neoteny may assume
maladaptive characteristics and become manifested in distorted and freakish physical expressions, as a result
of self-imposed breeding preferences. Neotenous traits may become cultural ideals and selected for. Thus,
the rate at which such traits are developed adapts itself to the pace dictated by cultural change, which is much
faster than that of genuine neoteny in a natural setting.
The pseudo-neotenous features displayed by domesticates illustrate this process at its best: during the
span of only a few generations, a priori decided-upon traits pursued in breeding (like docility, milk or wool
output, meat quality) result in an apparently neotenous appearance that does not serve the biological fitness
of the domesticated animal. This is the ‘domestication syndrome’ or, in our case, self-induced, or pseudo-
neoteny. Therefore, genuine and maladaptive neoteny – however similar in morphological expression – must
be understood as the biological and, respectively, the cultural aspect of the same process.
I keep on stressing that biological neoteny does not necessarily lead to domestication, but domestication
results inevitably in the accelerated acquisition of apparently neotenous features. Wild boars did not become
pigs because of neoteny, but pigs display neotenous features because of the domestication of wild boars
(Frantz et al. 2015). By the same token – however shocking this statement may appear – Neanderthals did
not become ‘anatomically modern’ humans because of neoteny, but AMHs display neotenous features be-
cause of the self-domestication of Neanderthals. Pigs are not wild boars, and AMHs are not Neanderthals.
Genetic changes induced by domestication may lead to speciation (ibid., Tchernov and Horwitz 1991).
Selecting for traits that are considered advantageous in a constructed cultural niche – like docility and
sociability, which are the cultural repression of aggressiveness – is like being bred by selecting for specific
behavioral traits, very much like Byelayev (1969, 1979) did with his foxes. In other words, the cultural niche
was not elaborated by domesticates, but the realities and breeding preferences within the cultural niche do-
mesticated humans.
Helmuth Nyborg’s suggestion (1994) that ‘feminized,’ slower maturing ‘neotenous androtypes’ will dif-
fer from ‘masculinized,’ faster maturing ‘androtypes’ by having more rounded and fragile skulls, wider hips,
narrower shoulders, less physical strength, live in cities – as opposed to living in the countryside – and by
receiving higher performance scores on ability tests, must also be understood as a post-biological pseudo-
neotenous manifestation. Nyborg theorizes that certain ecological situations would favor the survival and
reproduction of the ‘masculinized androtypes’ due to their sheer ‘brutal force,’ while other ecological situa-
tions would favor the survival and reproduction of the ‘feminized androtypes’ due to their ‘subtle tactics.’
Let us – following Bednarik (2008) – call such culturally-fabricated ‘androtypes’ gracilized phenotypes.
Gracilization does not occur in a natural environment, but it takes place in an artificial, culturally-constructed
niche.5
Here, Sapolsky’s (1996) thoughts on the relationship between hierarchy, aggressiveness and chronic
stress are very well illustrated: the environment in which Nyborg’s ‘feminized androtypes’ thrive is the
hierarchically-organized and socially-complex cultural niche. Domestication and hierarchy are complemen-
tary to each other, for obvious reasons. According to Sapolsky, the chronic stress that characterizes social
complexity, besides shrinking our brains, also fattens our bellies, which is precisely what happens to Ny-
borg’s gracilized ‘androtypes’ in a strictly cultural environment.

Nyborg’s ‘feminized androtypes’ could be called with confidence ‘Nyborgs’ because, to an extent, they are reminiscent of ‘Cyborgs.’
Transhumanist fantasies (Bostrom 2005) should have accorded more attention to the phenomena that I discuss in this section; appar-
ently, for the last 40 millennia, human evolution is already prescribed by humans, and technology seems to play an important role in
creating a culturally-engineered human phenotype that displays all the characteristics listed by Nyborg (1994). Self-domesticated
Nyborgs are very much like consciously planned Cyborgs.

The ‘smartness’ of such ‘androtypes’ is, therefore, relative. The reduction of the neural storage capacity,
as Bednarik (2014b) suggests, is paralleled by our absolute reliance on the external storage of information.
The brain specializes in the causal reading of exograms and cognitive functions become reduced to the
ability to access, but not to store or process information. Social learning becomes thus centered on the trans-
mission of the know-how to access knowledge, but not knowledge itself.

Managing the Risks of Cultural Evolution 45
The often-mentioned gentleness and peacefulness that characterize immediate-return societies (Marshall
1989 [1959]) can thus be related to the leveling mechanisms that inhibit any expression of hierarchy. There
is even an anthropological example of a society that overtly exhibits all the behavioral characteristics that
were observed with bonobos. I have in mind the Onge of Little Andaman Island, a markedly neotenous
Negrito population that is closely related to the repeatedly mentioned Jarawa. The first Europeans who have
encountered them were shocked by the Onge’s public display of affection, their need for permanent physical
contact, their peacefulness and egalitarian principles (Portman 1899). Unfortunately, today the Onge are on
the brink of extinction, but I am confident that before being contacted by outsiders, they would have qualified
for being added to the list of immediate-return and egalitarian hunter and gatherer societies which, sadly, is
restricted to the six populations already mentioned.
– Leveling mechanisms are stabilizing techniques (i.e., cultural neoteny slows down the pace at which culture
evolves) which manage cultural elaboration and do not let it go beyond a level of sufficiency (cultural pro-
genesis). Thus, biological evolution keeps up with the stabilized rate at which culture evolves and there is
no need for an artificial buffering between the two. The absence of cultural specialization allows neoteny to
continue its role in biological evolution and its psychological side-effects manifest themselves in the texture
of immediate-return hunter-gatherer societies. Hierarchy and aggressiveness become inhibited, stress is re-
duced, and egalitarianism and peacefulness become encouraged.
– Conversely, coping/buffering mechanisms are accelerating techniques (i.e., they inflate the pace at which
culture evolves) which encourage cultural elaboration to go beyond a level of sufficiency, to one of efficiency
IFIRARQ 16
46 Holocene Crossroads
(cultural hypermorphosis). Thus, biological evolution starts lagging behind the accelerated rate at which
culture evolves and there is a need for an artificial buffering between the two. Cultural specialization prevents
neoteny to continue its role in biological evolution and the shortcuts taken for keeping up with the ever-
increasing rate at which culture evolves leads to rapid gracilization. Like genuine neoteny, its maladaptive
cultural dimension (gracilization, domestication syndrome) is also accompanied by psychological side-ef-
fects.6 Aggressiveness becomes culturally repressed and becomes socially-learned docility, chronic stress
becomes a permanent feature of the cultural landscape and hierarchical structures remain the main social
signature of trans-egalitarian societies (sensu Hayden 2003).
Fig. 5 – a. Depiction of male/female relative cranial gracility in Europe through time: the decline in robusticity is gradual in
males, but accelerated in females between 40 and 30 ka (Bednarik 2008, 2017) / b. Osteological evidence (Stynder 2006)

pedomorphic cranial morphology. But: large body size/robust bone structure until c. 8,000 BP (Bräuer and Rösing 1989).
European cognitively modern Aurignacians were – according to Bednarik’s (2007) convincing and already
discussed evidence – very likely archaic Neanderthaloids or their still markedly robust descendants. Pheno-
types that can be undoubtedly defined as ‘anatomically modern humans’ (AMHs) do not appear in the Eu-
ropean archaeological record before the Gravettian (ibid.) that is, at c. 30 ka ago.

Schizophrenia and autistic disorders are hypothesized to be consequences of self-domestication (Benítez-Burraco and Boeckx
2015; Benítez-Burraco et al. 2016) and believed to have emerged after ‘anatomically modern’ (i.e., self-domesticated and thus
gracilized) humans diverged from Neanderthals (Srinivasan et al. 2015). Moreover, schizophrenia and autistic traits are also
believed to have played a role in Upper Paleolithic cave art (Spikins 2018). The etiology of the said disorders was directly
associated with genetic defects in which large segments of DNA are either duplicated or deleted and which result in a neuro-
logical syndrome known as 1q21.1 deletion/duplication (Fiddes et al. 2018). I will return to these observations in my discussion
of Solutréan/Magdalenian cave art.
G.F. Steiner
Managing the Risks of Cultural Evolution 47
Conversely, African cognitively modern humans (CMHs) at around 30 to 20 ka ago were also markedly
robust, far from the popular image of the ‘Bushmanoid’ AMH (Stynder 2006).
For example, the reassessment of the whole Klasies fossil assemblage shows that although some speci-
mens fall within the range of variation typical of modern humans (Rightmire and Deacon 1991), the majority
are surprisingly robust, suggesting a mosaic evolutionary pattern in which cranial and postcranial elements
evolved at different rates. The fossils are dated to approximately 90,000 BP (ibid.). On the other hand, exca-
vations at Die Kelders and investigations of a very important site at Blombos have produced several teeth,
which share most of their attributes with modern African populations, but still of a very ‘generalized’ type,
far from what we associate with ‘Bushmanoid’ morphology. The ages for these specimens were suggested
to be of 60-80,000 years BP (Mitchell 2002).
As I have discussed elsewhere and, as also suggested by Ashley-Montagu (1989), the Bushman popula-
tions of southern Africa display highly neotenized features when compared to Caucasians or the ‘general-
ized’ African phenotypes. A globular braincase and a bigger brain (in brain-to-body ratio) are the differences
which are relevant here, because of the psychological implications of neoteny (Charlton 2006) which, in
their turn, affect behavior. As seen in the comparison between chimpanzees and bonobos (de Waal 2002),
neoteny reduces aggressiveness and hierarchical tendencies. Therefore, it is not far-fetched to think that the
archaic inhabitants of Upper Paleolithic Eurasia and the still markedly robust Africans around 60 ka ago
were behaviorally more aggressive and socially more hierarchical than contemporary (neotenous) Bushmen
or (gracilized) Europeans. Whereas the ‘gentle’ and ‘harmless’ character of the ‘savage’ Bushman (Marshall
1989) is a consequence of genuine biological neoteny, the ‘docility’ of the ‘civilized’ descendants of Upper
Paleolithic Europeans is very likely a behavioral outcome of maladaptive cultural gracilization (SGM p. 18;
Fig. 5).
Although aggressive traits are culturally-suppressed on an individual level, they are still present in the
fundamental values that determine the development of ‘civilized’ culture and society. Conversely, in vertical
cultural orientations, aggressiveness and hierarchy must have been biologically reduced before the emer-
gence of ‘egalitarian societies’ and culturally inhibited in already egalitarian settings (in which leveling
mechanisms manage the risk of their possible re-emergence – which should not be perceived as repression,
because there is no contradiction between biological and cultural ‘inclinations.’).
Aggressiveness and hierarchical group organization are pre-modern and universal behavioral traits, the pres-
ence of which, with archaic populations that otherwise display all the signs of cognitive modernity, should
not come as a surprise.
The use of ocher, incisions on lumps of ocher and geometrical etchings on ostrich eggshells point toward
such a cognitive modernity in the case of the anatomically still robust Stillbay and Howieson Poort people
(Stynder 2006). Lumps of differently colored ocher were also found in Tanzania, and dated to the same
period, i.e., 70 to 60 ka ago (Schepartz 1988). But, as emphasized above, cognitive modernity is far from
being an index of behavioral modernity, and the ‘archaic’ anatomy of these African CMHs raises a few
questions about their behavioral and social characteristics, which must have been very different from those
of their peaceful and egalitarian descendants.
During the Late Pleistocene, a genetically Khoe(san)-like population already dominates the ethnograph-
ical landscape of southern and East Africa (Tobias 1978; Nurse et al. 1985; Schuster et al. 2014). Interest-
ingly, the KhoeSan people of southern Africa have long been viewed as the direct ancestors of the earliest
anatomically modern Homo sapiens. According to Tobias (ibid.), the geographical range of early Khoe(san)
groups extended over much of southern, eastern and north-eastern Africa. Genetic research carried out over
the last 20 to 30 years appears to reinforce the longstanding hypothesis that the Khoe(san) were the aboriginal
population of these regions (ibid.; Nurse et al. 1985; Schuster et al. 2014). More genetic research continued
in this vein and, interpreting the results, Soodyall and Jenkins (1992) placed the divergence between the three
major genetic groupings of sub-Saharan people – Khoe(san), Pygmy and Negroid – to approximately
150,000 years BP. Veeramah et al. (2012) concur with this early date, and Singer and Wymer (1982) went
IFIRARQ 16
48 Holocene Crossroads
as far as to suggest that there might have been a biological continuity between the Klasies River people
mentioned above and the ancestors of modern KhoeSan. However, an almost complete human cranium that
was discovered in 1954 in the Hofmeyr district of the Eastern Cape Province contradicts such an interpreta-
tion. Grine et al. (2007) report a date of around 36,000 years for this specimen. Its morphology has been
described as being a mosaic of archaic and modern traits (Morris and Grine 1999). Grine et al. (ibid.) report
that the Hofmeyr cranium falls outside the range of variation displayed by modern KhoeSan crania in most
aspects of craniofacial morphology. Instead, their measurements of facial dimensions and vault curvature
surprisingly reveal a markedly robust individual, which situates the Hofmeyr cranium within the range of
variation of European Upper Paleolithic crania.
Morris (2002, 2003) has hypothesized that the San (Bushman) phenotype arose relatively late in South
Africa. According to Morris’ hypothesis, the still robust common ancestors of modern southern African
Khoe and San populations underwent a bottleneck situation associated with the Late Glacial and the Last
Glacial Maximum (LGM) at c. 24,000 to 17,000 BP. At this time the cool, dry glacial climate would have
resulted in the desertification of much of southern Africa, particularly the inland regions. A scarcity of inland
archaeological occurrences suggests significant depopulation of these areas (Mitchell 1990; Wadley 1993).
At the same time, a large area of land would have been exposed along South Africa’s southern coast, with
an extended coastal plain of over 100 kilometers at some places (van Andel 1989). Unlike the interior, the
better watered southern coastal region displayed comparatively denser human occupation at this time
(Parkington 1990). These evolutionary processes would eventually have resulted in the differentiation of this
coastal population from other African populations and thus to the emergence of ancestral KhoeSan (Morris
2002, 2003).
At the end of the glacial period, there would have been a population expansion that would have resulted
in the introduction of KhoeSan morphological traits into the rest of southern Africa (ibid.). Osteological
evidence (Bräuer and Rösing 1989; Morris 2002; Stynder 2006; Stynder et al. 2007) appears to support
Morris’ hypothesis of a relatively recent southern African origin of recognizably KhoeSan cranial morphol-
ogy. In accordance with his model, terminal Pleistocene/Early Holocene human crania do indeed display a
general KhoeSan craniofacial pattern, particularly with regards to upper facial form (Bräuer and Rösing
1989). According to them, fossils such as the 10,000 years old Albany Man and various similarly aged fossils
from sites such as Matjes River Rock Shelter, Wilton Large Rock Shelter and Oakhurst, possess the small,
broad upper faces typical of recent KhoeSan populations.
However, one notable aspect of these Early Holocene people is their large size and robust bone structure,
which was for a long time thought to be rare amongst recent KhoeSan people (ibid.). Such changes in cranial
morphology may be taken as a sign for an incipient or ongoing neotenization process that would reach its
full expression following the isolation of certain groups of this robust, but undoubtedly KhoeSan phenotype.
The psychological side-effects of neoteny are entailed in cranial morphology and not necessarily in body
size. However, neotenization seems to have continued and, indeed, small body size would appear, but only
starting with the mid-Holocene (Fig. 5).
At approximately 8,000 BP, a dramatic reduction in stature and robustness seems to have occurred
(Pfeiffer and Sealy 2006; Stynder 2006; Stynder et al. 2007). A slight increase occurs at around 4,000 BP
which, I would suggest, was the aftermath of the arrival of Khoe pastoralists from East Africa, as hypothe-
sized by Blench (2008) and Smith (2005).
G.F. Steiner
Managing the Risks of Cultural Evolution 49
Beside encapsulation, another social theory regarding the emergence of IR societies is ‘competition,’ as
suggested by Hayden (1990). However, given Hayden’s (2003) preoccupation with ‘trans-egalitarian’ soci-
eties – in which competition, indeed, becomes important – ascribing competitive characteristics to an econ-
omy that strives to reduce every aspect of competitiveness does not make much sense.
‘Risk reduction’ (Hegmon 1991; Kelly 1991) is another social theory that tries to explain the emergence
of egalitarian societies and immediate-return strategies, and this would make sense, given its compatibility
with an ecological theory (Binford 1980; Oyuela-Caycedo 1996) which proposes that IR strategies develop
where resources are patchy, in contrast to DR economies, which emerge in lush environments. Therefore,
disruption and isolation would explain better the original impulses toward IR strategies. Hxaro, as already
discussed, is also considered to be rooted in such risk-reduction techniques (cf. Wiessner 1977).
Although the ancestors of Pygmies and Khoe(san) separated approximately 150 to 110 ka ago (Soodyall
and Jenkins 1992; Veeramah et al. 2012), both genetic lines, as argued above, were phenotypically robust.
Typical ‘Bushmanoid’ characteristics of cranial anatomy would become noticeable only during the terminal
Pleistocene but these ancestral KhoeSan were, likewise, still remarkably robust (Stynder 2006). Present (pe-
domorphic) phenotypes appear in the osteological record only starting with the Holocene and are associated
with the Lockshoek – Interior Wilton – Smithfield B Later Stone Age (LSA) sequence (Bousman 2005).
Therefore, Tobias (1978) and Schuster et al. (2014), in their mention of a Khoe(san) element that dominated
East and southern Africa approximately 80,000 years BP, refer likely to the genetic line that would, during
the Holocene, result in KhoeSan phenotypes as we know them today.7
Interestingly – but not surprisingly – these populations were characterized by DR strategies (see Mitchell
2002 and references therein; Bousman 2005): storage pits were unearthed and identified even in the Kala-
hari!
Similar population fragmentations occur in Southeast Asia where, like in Africa, a phenotypically modern
population continuity was once proposed. The ‘Negrito hypothesis’ speculated that a shared phenotype
among various contemporary groups of hunters and gatherers (dark skin, short stature, peppercorn hair) was
due to common descent from a region-wide, pre-Neolithic substrate of humanity (see Endicott 2013). Pop-
ulations answering this description are found in and around the forests of Peninsular and Island Southeast
Asia, the most widely reported being those of the Andaman Islands, Malaysia, and the Philippines. ‘Negritos’
were presumed to derive from an early ancestral population whose former distribution may have also in-
cluded parts of New Guinea and Australia, but who were either absorbed or replaced by later migrants (Bar-
nard-Davis 1867; de Quatrefages 1895; Radcliffe-Brown 1922).
For the Out-of-Africa scenario to accommodate the Negrito hypothesis, it would be reasonable to antici-
pate evidence for short stature in the fossil record. Possible evidence for a hominin of short stature in the
early paleoanthropological record of the northern Philippines is limited to a single metatarsal, whereas later
human remains indicate predominantly robust phenotypes (Dizon et al. 2002; Détroit et al. 2013). A second
expectation of placing the Negrito hypothesis within the Out-of-Africa hypothesis is that there should be
some degree of shared retention of phenotype among other populations, in particular the African Pygmy
groups (for a genetic history of Pygmies, see Batini et al. 2011).

The degree of biological relatedness between eastern and southern African Stone Age hunter-gatherers has long been a subject of
interest and still wrongly interpreted in recent research. For example, Willoughby et al. (2018) describe Stone Age teeth from Magu-
bike rock shelter in Tanzania as ‘‘closely resembling those of the San of southern Africa.’’ Theoretically, the description is correct
but very misleading. Schepartz (1988) critiques the presumption that EA/SA Late Pleistocene people were ‘unreduced’ robust ‘Bush-
manoids.’ Rightly so: as Morris (2002) attracts the attention to, San (Bushmen) are a relatively late South African development. It
was an ancestral proto-Khoe(san) stock that inhabited EA and SA in the Late Pleistocene, which itself would split into southern
(KhoeSan) and eastern (Khoe) branches at 35 ka (Tishkoff et al. 2007). The LGM leads to isolation and the ancestors of San split at
around 27 ka (Pickrell et al. 2012) in southern Africa and those of the KhoeHadza and of the Sandawe become separated at around
the same time (Veeramah et al. 2012). The Hadza would become isolated from the ancestors of East African Khoe at c. 18 ka (Pickrell
et al. 2012; Tishkoff et al. 2007). Therefore, and in order to avoid confusion, Khoe(san) in the text is the designation that I adopt for
the (pre 35 ka) common genetic ancestors of East African Khoe, Sandawe and Hadza, and of the southern African Khoe and San. By
the same token, the designation KhoeSan is used to denote the southern (post 35 ka) branch of the Khoe(san), i.e., the ancestors of
modern Khoe and San.
IFIRARQ 16
50 Holocene Crossroads
Comparing postcranial measurements of Aeta (Philippines) and Andamanese with African, Asian, and
Australian hunter-gatherers suggests that the phenotypic variation does not support the existence of a generic
Pygmy or Negrito phenotype, past or present (Stock 2013). These findings do not rule out an ancestral con-
nection between these populations, but any account of the Negrito hypothesis has to explain this amount of
physical variation.
An alternative explanation for the Negrito phenotype is that of convergent evolution, whereby similar
physical traits developed independently among multiple populations. An explanation for the existence of
short stature is that it evolved as a ‘life-history trade-off’ favoring early reproduction and cessation of adult
growth (neoteny), in order to enable flexibility for novel biological adaptations in the remote rainforest en-
vironments in which certain groups became isolated (Migliano et al. 2007; Endicott 2013).
In other words, the southern African scenario seems to repeat itself in Southeast Asia and the dark, short-
statured and peppercorn-haired Negritos, however reminiscent of African Pygmies, apparently evolved lo-
cally, from robust populations that underwent a neotenal leap during the Holocene.
To sum up, I would hypothesize that during the Last Glacial, and especially the LGM, certain human popu-
lations in a bottleneck situation that became isolated in the deserts of interior southern Africa and the
drought-stricken savannas of East Africa, but also in the Central African and Southeast Asian rainforests,
reversed to immediate-return strategies (DR proved to be practiced in more lush areas, see the Albany in-
dustry of the Oakhurst complex in South Africa [Mitchell 2002; Bousman 2005]). IR strategies would have
granted more flexibility, a generalized ‘new start’ from which novel cultural steps could have been taken.
Indeed, the interior Lockshoek industry – belonging to the same Oakhurst complex of which the coastal
Albany industry or the savanna Pomongwe tradition are DR examples – was an arguable reversal to imme-
diate-return subsistence. Moreover – and as the osteological record indicates – a neotenal leap seems to have
taken place at the beginning of the Holocene: short stature and pedomorphic characteristics evolved, in a
similar fashion like that proposed for Southeast Asia, which was interpreted as a ‘life-history trade-off’ fa-
voring early reproduction and cessation of adult growth (Migliano et al.2007; Endicott 2013). This would
also be compatible with the ‘risk management’ hypothesis for the origins of immediate-return hunters and
gatherers, as proposed by Hegmon (1991) and Kelly (1991).
Apparently, the economical reduction to a more generalized, but more flexible IR base was followed by a
biological reaction, expressed in further neotenization which, in its turn, resulted in a more generalized and,
therefore, more flexible behavioral and social base. I would like to emphasize – again – that immediate-
return subsistence is not synonymous with egalitarian behavior and social organization. IR is a reduction
from DR to a non-specialized economy that ‘freed’ the isolated groups of the interior from cultural entan-
glement (sensu Taylor 2010), and in which biological processes could act without interference.
The Holocene neotenal ‘sudden jump’ – beside the obvious physiological flexibility that it pertained – must
have also leveled hierarchical/aggressive tendencies and granted a higher level of sociability, which would,
inevitably, lead to egalitarianism. Therefore, higher levels of sociability based on reduced levels of hierarchy
enabled a novel type of social complexity.
Hxaro – in the southern African case – is the key to such a non-committed complexity based on maximum
flexibility. It did not emerge as a coping technique meant to counter the dangers of the ‘treadmill effect,’ but
as the result of a biologically-granted potential. By the incipient Interior Wilton (formerly Smithfield A, 8
ka ago) leveling mechanisms start being elaborated as the stabilizing techniques that would eventually en-
trench egalitarianism during the classic (7 to 4 ka ago) and developed (4 to 2 ka ago) stages of the same
Interior Wilton tradition (see the evidence cited by Stynder [2006] regarding the increasing occurrence of
hxaro exchange goods at around 10 ka ago).
IR strategies are a ‘primitivism’ carried into the new cultural dimension, which is an egalitarian (sensu
Woodburn 1982) and affluent (sensu Sahlins 1972) society. The ability to retain such a primitivism – or to
G.F. Steiner
Managing the Risks of Cultural Evolution 51
reverse to such a less specialized primitive stage – is the expression of the flexibility that characterizes ver-
tical evolution in biology (Blaga 1976 [1943]) and, as it seems, in culture (Steiner 2016, 2017). The cultural
‘achievement’ in this case is not the IR economy, but the egalitarian character of the societies that have
emerged immediately after employing such a generalized tactic. Therefore, the comparison between the Eu-
ropean Mesolithic and the southern African Wilton industry (and the subsequent Smithfield B tradition) may
be valid on the technological (material) plane, but it cannot be extended to the behavioral (social) and – as
it will soon become evident – cognitive (mental) levels.
During the Last Glacial, isolated Neanderthal groups in West Eurasia did not revert to a ‘primitive’ economy
but, instead, they ‘developed’ SMUs, as documented by Richter (2000). The strategy was compensatory in
character and was meant to entrench technological achievements and safeguard them against cultural loss.
Hierarchical and aggressive robusts living in an already well-consolidated and ratcheted cultural niche –
which was likely modeled on the very values entailed in such behavioral traits – were not flexible enough to
react biologically to the hardships of the LGM, which affected them incomparably harder than the environ-
mental conditions experienced by their African cousins. After tens of millennia of cumulative cultural evo-
lution, they have reacted culturally, with an emphasis on technological innovation and social complexity.
The adoption of a cumulative type of cultural evolution 60,000 years ago by cognitively modern but
anatomically archaic H. sapiens neanderthalensis in western Eurasia had paved the way to the emergence
of behaviorally (hierarchical, docile) and anatomically (gracilized) modern populations.
Conversely, the adoption of a reductive type of cultural evolution during the final Pleistocene by cogni-
tively modern but anatomically still robust Homo sapiens in southern Africa had paved the way to the emer-
gence of anatomically (neotenous) and behaviorally (egalitarian, peaceful) modern populations.
7. Cultural Speciation
In southern, Central and East Africa, very much like in parts of South East Asia, the isolation that was
brought about by the climatic upheavals of the LGM was answered by making use of the degree of flexibility
that characterizes cultural orientations that are still not vertically or horizontally committed. Such a reductive
cultural step had apparently enabled the perpetuation of biological tendencies, i.e., of neotenous develop-
ments.
Paleoanthropological evidence – as discussed before – supports such a possibility: the biological conse-
quences of the LGM cultural reduction become manifested by the Early Holocene, when human morphology
in the above-mentioned remote regions already starts displaying markedly neotenous features.
Small body size would appear in isolation, as a ‘life-history trade-off’ favoring early reproduction and
IFIRARQ 16
52 Holocene Crossroads
cessation of adult growth (Migliano et al.2007). In southern Africa, at approximately 8,000 BP, a dramatic
reduction in stature and robustness seems to have occurred (Pfeiffer and Sealy 2006; Stynder 2006; Stynder
et al. 2007). The date corresponds not only with the Holocene mammalian size reduction, but also with the
incipient phases of the Interior Wilton industry and the appearance of hxaro exchange artifacts in the archae-
ological record. The similarities between the Interior Wilton and modern San technological traditions and
the evidence for hxaro which, in its turn, may be related to the leveling mechanisms that stabilize social and
technological developments in egalitarian societies point to a relatively recent origin of the latter.
In this context, the development of the cultural flexibility entailed in the leveling mechanisms documented
by Woodburn (1982) is the tangible side-effect of ongoing neoteny in vertical cultural orientations. There-
fore, the o’-y axis of the cultural field is the natural extension of the vertical coordinate of the biological
field. Hence, vertical evolution in the cultural field can be confidently defined as biological-cultural co-
evolution, in stark contrast with horizontal cultural trajectories which, for reasons discussed below, will be
defined as cultural–biological coevolution.
The climatic deterioration of the LGM was felt more severely in Eurasia, where populations with a 40,000
years history of cumulative cultural evolution (Richter 2000) had lost much of their cultural flexibility be-
cause of their specialization to the demands of already well-established and elaborate cultural niches. In the
harsh Eurasian paleoclimate – which had also determined the horizontal turn taken in cultural evolution
during the Middle/Upper Paleolithic transition – ‘regressions’ became unimaginable, not only because of the
environmental realities that would not have allowed for an immediate-return subsistence, but also because
of an already advanced stage of gracilization – the morphological consequence of ongoing self-domestica-
tion which, according to Bednarik (2007), had reached an archaeologically detectable stage at around this
time (c. 30-27 ka).
The price of cultural ‘fitness’ came at the expense of biological flexibility and, therefore, the response to
the climatic challenge of the LGM was strictly cultural: instead of reduction, further elaboration seems to
have occurred. However, at least at this stage, the cultural compensation does not seem to have taken place
exclusively at the technological level: having in mind the grandiose and obsessive display of ‘creativity’
during and following the LGM, I would suggest that the compensation was mostly of a cognitive nature. As
I will soon explain, by ‘cognitive compensation’ I mean adjusting cultural behavior to the restricted cogni-
tive potentials that were the consequence of tens of millennia of niche construction and self-domestication.
The narrowing of the ‘cognitive ceiling’ is graphically illustrated in Fig. 4 (SGM pp. 14, 24): the ability
to shift the ‘contextual focus’ to its associative end (sensu Gabora 2003) decreases in direct proportionality
G.F. Steiner
Managing the Risks of Cultural Evolution 53
According to a slowly emerging new paradigm, agriculture is far from being an exclusively material/tech-
nological ‘innovation.’ Contrary to what was previously thought, the etiology of the Neolithic cultural leap
may also be understood as a cognitive reaction to the environmental changes of the Younger Dryas.
In a manner that is reminiscent of the cognitive response of Solutréan and Magdalenian Europeans to the
climatic havoc of the LGM 8 millennia before them, Anatolian Early Holocene delayed-return hunters and
gatherers have suddenly started to display an obsessive preoccupation with symbolic constructs, which led
to collective grand-scale projects. Göbekli Tepe, a cultic site par excellence, is maybe the best example
(Schmidt 2003). Agriculture is believed to have commenced as a modality to support such ‘obsessions’ (ibid.;
Cauvin 2007).
By the same token and at the same time, the Natufians of the southern Levant developed strong symbolic
attachments to their settled way of life. The cultural rigidity that was the result of this cognitive specialization
inhibited the possibility of a ‘regression’ to nomadic life when the climate turned unfavorable. Instead, a
IFIRARQ 16
54 Holocene Crossroads
cultural step was taken, which was meant to support the said symbolic attachments and ratchet the settled
cultural environment in which they have developed.
Hayden (2003) theorizes that ‘trans-egalitarian societies’ have developed as a result of such symbolic
obsessions and that the grandiose Solutréan and Magdalenian cave art of Upper Paleolithic Europe points to
their emergence. Moreover, he forwards the hypothesis that feasting meant to display status and prestige
was an integral part of the ritual activities pursued in the painted caves. Despite that his evidence is not
convincing, feasting and orgies did indeed take place at Göbekli Tepe (Schmidt 2003) and, because of the
similarities between the Upper Paleolithic cognitive reactions to the LGM and the Neolithic Anatolian/Le-
vantine cultural responses to the Younger Dryas, I am inclined to take Hayden’s hypothesis in consideration.
Furthermore, given that the consolidation of prestige, power and status is also pursued in cumulative cultural
evolution, ‘trans-egalitarian’ societies may be directly contrasted with ‘egalitarian’ societies in which, the
development of prestige, power and status is actively discouraged.
Only at this moment was the ‘sufficient’ Mesolithic toolkit expanded, i.e., adapted to novel agricultural
needs, and the obsession with technological ‘advance’ and domestication became irreversibly institutional-
ized (for a discussion, especially regarding ‘the domestication of metals,’ see Steiner 2010).
Levantine and Anatolian agriculturalists expanded to Europe (Haak et al. 2010; but see also Diamond’s
[1997] ‘geographical axis’ argument, which also explains the horizontal orientations that were imposed on
most delayed-return cultures), where they encountered a culturally-gracilized population with a similarly
rich history of compensatory cultural niche construction. Their values were compatible with those imported
by the Neolithic newcomers and they were, apparently, easily adopted.
Undoubtedly, immediate-return hunters and gatherers display a higher degree of neoteny than the self-do-
mesticated descendants of the Natufians. Genuine neoteny occurred in the first case (Holocene mammalian
body size reduction), and pseudo-neoteny in the second example (Neolithic domesticate body size reduc-
tion).
In conclusion, the increased biological flexibility granted by the cultural reduction of the terminal Pleis-
tocene enabled neoteny to continue its natural course not only with the San of southern Africa, but also with
populations that found themselves isolated in Central/East Africa and in South East Asia. The still robust
ancestors of Hadza and Sandawe became separated during the/as a result of the environmental changes of
the LGM, very much like the ancestors of Pygmies or Negritos. Short stature and other (mostly cranial)
pedomorphic characteristics – and, as a behavioral side-effect of such neotenous developments, egalitarian
societies – emerged in all these locations, during the mid-Holocene. Therefore, and as already stressed, the
perception of immediate-return subsistence strategies as a primitive and ancestral stage that would evolve
toward more elaborate delayed-return economies is, basically, wrong.
By the same token, egalitarian societies are not ancestral to more complex and hierarchical social struc-
tures, but a relatively recent behavioral achievement.
The linear perception that plagues our understanding of ‘cultural evolution’ takes us back to the implicit
linearity presumed in the ‘emergent’ to ‘mobilized’ progression of symbolling abilities, which was the start-
ing point of this paper. In the following, I will focus on the cognitive implications of cultural heterochrony
and on the accelerated or, conversely, the delayed application of symbolling abilities that were, arguably,
already in the possession of our Middle Paleolithic ancestors.

hunters and gatherers is considered to be c. 9 ka old. If these dates reflected the real age of African rock art,
one could argue for a relationship between the novel economical/social organization and the parietal art
which would, presumably, enshrine the ‘values’ of egalitarianism. Such an interpretation would, however,
imply the delayed emergence of cognitive abilities that were already at a ‘mature’ stage in West Eurasia,
millennia before their systematical application in Africa. But, as already emphasized in the previous section,
well-developed iconographic abilities in southern Africa were present long before the emergence of egali-
tarianism, at approximately the same time when they started to be systematically applied in Eurasia. San
rock art draws on figurative traditions inherited from non-egalitarian robust ancestors who had demonstrated
their ability during the Last Stadial (27 ka ago) in the Apollo 11 Cave (SGM p. 21).
The date at which the stone slabs were painted was determined using the accelerated mass spectrometry
(AMS) C14 method (Rifkin et al. 2015), which is more reliable than tentative dates based on archaeological
context or stylistic considerations.
We must consider the possibility that the iconographic ability was latently present and sporadically practiced
long before its application on a massive scale during the Holocene. The ‘artistic’ skills displayed in the
execution of the ‘first’ rock paintings illustrate clearly that the ability did not appear all of a sudden but,
when its application became meaningful, dormant traditions were revitalized and used on a large scale.
Therefore, reliable dates for the emergence of the systematic use of such latent abilities become imperative.
The problem with the above-mentioned tentative – but widely accepted – dates is that, as said, they are based
on stylistic considerations and on not too reliable archaeological contexts. In the case of immediate-return
hunters and gatherers – because of the stable character of their culture – the dates theorized by such ap-
proaches are questionable. Moreover, IR economies reduce cultural elaboration and do not produce unnec-
essary cultural artifacts (e.g. rock art).
However convenient an explanation of rock art as the illustration of novel economical/social realities
would be, only the reliance on direct dating techniques and archaeometry can offer an accurate understanding
of the relationship between rock art and the cultural contexts in which it became systematically applied. An
AMS carbon dating of San rock art from three locations was undertaken by Bonneau et al. (2017). Surpris-
ingly, the oldest dates were shown to be slightly in excess of 5 ka in SE Botswana and their age decreases to
c. 4 ka in Lesotho and the Drakensberg. These measurements confirm earlier AMS C14 results according to
which, the earliest directly dated South African parietal art – depicting human figures painted on exfoliated
slabs at Steenbokfontein – was estimated to be not older than c. 3650 BP (Rifkin et al. 2015 and references
therein).
Similarly, Batwa rock art is generally believed to be much younger than the > 14 ka attributed to it by
Namono (2012), namely, in the order of 3 ka. Hence, the earliest occurrences of Batwa and San rock art do
not necessarily reflect the emergence of egalitarian societies and, implicitly, they do not illustrate incipient,
but already well-established cultural norms of immediate-return hunters and gatherers.
Direct dating techniques place the emergence of San rock art traditions in a historical period that made
the application of already extant iconographic abilities meaningful – apparently, the ages attributed to the
oldest Bushman rock art coincide with the arrival of Khoe8 pastoralists in southern Africa (Smith 2005;
Blench 2008; but see contra, Sadr 2008).

The genetic similarities between modern Ethiopians and ancestral East African Khoe are highlighted in a study by Semino
et al. (2002) and confirmed by Schuster et al. (2014). I have already mentioned the dates at which the split between ancestral
eastern/southern African proto-Khoi(san) populations took place. An East African presence of this genetically Khoe(san) ele-
ment is beyond doubt. In isolation – both in southern and eastern Africa – some of these groups would return to IR strategies.
The East African Khoe on the other hand, did likely continue their DR subsistence strategies and, eventually, would adopt
pastoralism from their Cushitic neighbors. In EA they have impacted their close relatives, the Hadza, but also their more distant
cousins, the Sandawe. Their expansion to the south (Blench 2008) impacted various distantly related South African DR HG
Khoe groups, but also IR and egalitarian San. Likely, some of the newcomers adopted Bushman lifestyles and, opposite, some
Bushmen may have adopted pastoralism. Genetic exchange must have also been common at the end of isolation.

In such a context, the advent of the Bushman figurative rock art style could be understood as an expression
of the need to re-affirm and illustrate egalitarian social/spiritual practices (depictions of communal ritual
dances), or to share experiences acquired in the trance-like condition that accompanies persistence hunt
(animal and therianthrope paintings, as discussed in another section). The accent lies on what differentiates
the San hunters-gatherers from the pastoralist Khoe.
A sense of threatened values and the exposure to an alien cultural environment must have triggered out
arguably extant but latent symbolling abilities which became meaningful as a modality to illustrate cultural
identity. Although abstract representation has also a long history in southern Africa (pre-Bushman cu-
pules/petroglyphs engraved on quartzite outcrops in the Kalahari were dated, based on paleoclimatic con-
straints and micro-erosion analysis, to 400 ka BP [Beaumont and Bednarik 2010]), figurative abilities were
opted for. I would suggest that abstract representation is preferred when the environment is conceptualized
(like in the Lower/Middle Paleolithic ‘calibration of reality’), while figurative depictions are more suitable
for the illustration of behavior in a conceptualized environment.9 The application of abstract or iconographic
expression is solely a matter of perspective and not of hierarchy or ability.
For example, Batwa rock art favors abstract expression (which does not exclude the ability for the fig-
urative, see the example of the Jarawa boy Emmy, as discussed in the introduction). The origin of the Batwa
style (SGM p. 20) also coincides with the emergence of an external threat to cultural identity, namely: the
Bantu contact. Pygmy beliefs exalt environmental harmony and the prosperity of people depends on it.
Harmony itself became threatened at contact and, rock art, very much like the molimo ceremony, was meant
to re-establish it (for a discussion, see Namono 2012).
The realities of contact (early Bantu contact at c. 3500 BP in the case of the Batwa; Khoe contact in
southern Africa at around 4,000 BP; Khoe interaction with the Sandawe and Hadza in East Africa at earlier
dates, as testified by the Kondoa rock art corpus [Bwasiri and Smith 2015]), could have resulted in encapsu-
lation, which Woodburn (1988) sees as one of the possible origins of egalitarianism. Indeed, encapsulation
might have resulted in the re-affirmation of egalitarian behavior and/or in the re-confirmation of environ-
mental harmony, as described above. Novel and more elaborate leveling mechanisms meant to inhibit the
accumulation of prestige must have also been devised during this turbulent period.

Figurative rock art can, to an extent, also describe the nature of reality: consciously executed super(im)positions may reflect
intentional meaningful relationships between the two layers, i.e., the manifestation of contradictory but potentially equal
causal probabilities (Lewis-Williams 1981).
G.F. Steiner
Managing the Risks of Cultural Evolution 57
The rock art of southern Africa is usually associated with the hallucinations of San medicine people, or
‘shamans’ (for accounts of San shamanism see Lee 1968; Marshall 1969). It is mistakenly believed that –
like in the classical example of Siberian shamanism – the Bushman medicine man performs the typical sol-
itary dance of the lone shaman (Witzel 2011). Bushman trance is communal, and because about half the men
and a third of the women in any camp are shamans and medicine men (Lewis-Williams 1988; Dowson 1994),
‘shamanism’ is very different from what this erroneous term invokes. The same interesting occurrence was
mentioned by Deacon and Dowson (1996), namely: among the /Xam Bushmen most individuals were once
able to enter a trance-like condition and experience directly what, in later times and once this faculty eroded,
would become the prerogative of the lone shaman. In Bushman medicine dances, the majority of people
enter a state of trance and, in that condition, they activate supernatural potency that they share it with those
less fortunate, in the form of communal healing.
Thomas A. Dowson (1994) has observed, researched, and documented such ritual contexts. He has recog-
nized the illustration of the phenomenon in the rock art of the now extinct Bushmen of Lesotho and the
Orange Free State, in which communal groups with a big number of ‘shamans’ are depicted in dancing
postures. The shamans are identifiable by nasal bleeding, therianthhropic features and a number of other
distinctive gestures and postures indicative of Bushman shamanic practices (Lewis Williams 1981). Dowson
attracts attention to the fact that they are uniformly painted: the figures are all more or less of the same size,
and there is no depiction of any person who is more elaborately decorated or dressed than any of the others,
shamans or non-shamans. Dowson suggests that such paintings point to social circumstances in which a
large number of people in a community were in the possession of the faculties that would later be the pre-
rogatives of the lone ritual specialist, and thus no one could become pre-eminent; even though shamans
could contact the spirit world, heal and make rain, ‘‘they were not better than anyone else.’’ Service to their
community was a natural choice, not a power base.
This situation is similar to that described by Marshall (1969), Lee (1968, 1979), Biesele (1978) and Katz
(1982) for parts of the Kalahari in the 1950s and 1960s when, as said, about half of the men and one third of
the women in any camp were in the possession of the ability to shift the contextual focus at will. This does
not necessarily imply that the ability was once universal and its documentation in the 1950s mirrors a cog-
nitive loss. I would suggest that the faculty was a development entailed in vertical cultural evolution, i.e., a
heightening of the ‘cognitive ceiling,’ as opposed to its narrowing in cumulative (horizotal) cultural contexts
(Figs. 4, 7). The psychological side-effects of neoteny must have been directly responsible for the acquisition
of such cognitive abilities.
Although some shamans gained reputation for being especially gifted healers, they did not accumulate pres-
tige or assume positions of leadership or more influence. They continued to take part in hunting and gather-
ing, made arrowheads and were treated like anyone else. Hence, the cognitive ability cannot be imagined as
preceding the emergence of egalitarianism which, as already discussed, may also be associated with the
psychological dimensions of neoteny. This kind of ‘ritual communality’ was also observed in the simbó
trance dance of the Sandawe of East Africa (Dempwolff 1916).
But –as Dowson notices in the same article – at a certain stage, the lone ritual specialist would take the
central place on the stage. This means that either too much prestige was accumulated by some gifted shamans
and they monopolized the ritual scene (by disregarding leveling mechanisms meant to inhibit such a possi-
bility) or that the ability to enter trance at will became eroded drastically, on a communal level. Dowson
(ibid.) follows the erosion of egalitarian trance and suggests that the change was due to neither of the possible
reasons mentioned above, but to external stress, namely: contact with the encroaching European colonists
and Bantu agro-pastoralists, and the social interactions with them. This was a second contact, which had
more far-reaching consequences than the arrival of Khoe pastoralists in southern Africa at around 4,000
years ago. (The same scenario may be suggested for the Sandawe and Hadza of East Africa, who were
similarly exposed to the values of Bantu, Cushitic and Nilotic agriculturalist and/or pastoralist populations.)
IFIRARQ 16
58 Holocene Crossroads
Dowson relies again on rock art in his illustration of the phenomenon. He cogently observes that, in such
cases, the social processes in the production of rock art involved not only the Bushman ‘artists’ and their
communities, but also the European colonists and Bantu-speaking agro-pastoralists. For example, Bushman
shamans – who were known for their efficiency in rainmaking – made rain not only for their own people,
but also for their Bantu neighbors and were, at least sometimes, rewarded by being given cattle or a portion
of the farmers’ crops (Hook 1908; Stanford 1910). The paintings therefore do not point to Bushman beliefs
exclusively. Bushman medicine men were only ‘contracted’ by the Bantu for their services and rewarded by
them. The farmers were probably the viewers of the paintings and the significance of these must have re-
flected beliefs that they were familiar with (Dowson 1993). Moreover, the rewards created a situation in
which the leveling mechanisms meant to inhibit the accumulation of prestige and property became seriously
threatened.
Hunting skills, like shamanic talents, are not equally distributed in a community, but meat is shared up
equally, and so is ‘potency.’ Leveling mechanisms take care that no prestige is accumulated, neither by the
talented hunter, nor by the gifted shaman.
The changing roles of shamans can be followed in parallel with the chronology of the paintings that depict
medicine men/women in different ways: in communal settings as described above, and as pre-eminent ‘lone’
ritual specialists. Beside the rewards for rainmaking, the marriage of San women into farming communities
resulted in some Bushman families acquiring cattle through the payment of the bride price. In some circum-
stances Bushman ‘chiefs’ emerged and controlled territories of their own. Some of these chiefs were either
rainmakers themselves or entered alliances with rainmakers. Power and prestige were accumulated in addi-
tion to wealth, and leveling mechanisms became meaningless.
Increasing sedentary lifestyle followed, and the cave shelters chosen by shamans became associated with
potency, prestige, and power over resources, that is, over cattle and crops that were either the reward for
their services or acquired for their own sake.
Where the land was appropriated by white farmers, some of the Bushmen – including shamans – were
forced to accept permanent employment with them. They became fewer and itinerant, moving from farm to
farm to perform their healing rituals. Slowly, their fame as healers and their wealth in cattle kept at a home
base transformed them into political – and not just spiritual – ‘leaders’ (Guenther 1986). Moreover, when
the nineteenth-century colonial presence had all but annihilated the herds of game, and when grazing and
agricultural land replaced former hunting and subsistence grounds, life without close ties with agro-pastor-
alist Bantu chiefs became impossible, and an increasing number of Bushman families went to live in the
chiefs’ villages. Among these families were also rainmakers, whose descendants are still recognized and
respected in many parts of southern Africa. According to Jolly (1986), and Prins (1990) some of these people
continued painting until the end of the nineteenth-century. Then, as Dowson sees it, the ‘potency’ of the
images painted in abandoned rock shelters eroded gradually because of their painters’ continuing residence
in the farmers’ villages, and Bushman healers and rainmakers ceased making rock art.
Dowson restricts his research to an area known to have been a last refuge for comparatively ‘free’ Bushman
communities. The sequence from communal trance to specialized shamanism can be followed in the rock art
of the area, and relevant superimpositions that have been found in rock art panels suggest that the chrono-
logical sequence of the changes discussed in his article correspond with that of the rock art.
Bushman shamans responded to changing social circumstances in innovative ways, in other words, they
were adapting to the culture of their agro-pastoralist neighbors.
Forager communities had formerly maintained long-distance relations between scattered groups and
when resources within a camp’s territory were seriously reduced – as a result of drought or other factors –
members of that camp could resort to their long-distance relations and go live with other groups (see
Wiessner’s [1977] description of hxaro networks).
By the nineteenth century, the number of communities was so reduced, and resources so greatly dimin-
ished that people could no longer resort to this option for their long-term survival. Therefore, new relations
G.F. Steiner
Managing the Risks of Cultural Evolution 59
were forged with their Bantu neighbors, and a gradual – but destructive – adaptation to their cultural needs
and values occurred.
To sum up, the transformations documented by Dowson reflect behavioral changes that were imposed on
the Bushmen of southern Africa. Pictorial representations gained in importance during the first contact (when
they re-affirmed threatened egalitarian practices) and, again, following the second contact (when they ac-
companied the adaptation to an externally-imposed cultural environment and the gradual erosion of previous
cognitive abilities). Iconographic expression did not appear all of a sudden as ‘mature’ cognitive faculties,
but an already extant iconic skill became ‘mobilized’ in novel cultural environments.
Paradoxically, the massive and systematic application of symbolling abilities during the African Late
Stone Age (abstract in the Batwa example, or figurative with the San and Sandawe) does not indicate the
acquisition of ‘superior’ or elaborate cognitive potentials but, quite the opposite, it may be perceived as an
index of cognitive ‘loss.’
Therefore, the Upper Paleolithic cognitive ‘big bang’ associated with the Franco-Cantabrian iconographic
explosion must be reconsidered. The sheer scale at which iconographic abilities were applied may denote
cognitive losses of a much higher magnitude than those encountered by the discussed egalitarian societies
of Africa.
I would suggest that the sudden and massive display of figurative ‘artistic’ abilities – which is the hallmark
of this crucial period – illustrate, literally, the application of such coping techniques.
I have equated coping mechanisms with cultural acceleration (marked on the horizontal axis of the
cultural field), as opposed to leveling mechanisms, which I have associated with cultural stabilization (as
marked on the vertical coordinate of the field). I have also floated the idea that the rock art traditions of
egalitarian hunters and gatherers are the expression of such a cultural stabilization: I have theorized that the
massive application of latent symbolling abilities was triggered out at the contact between these hitherto
isolated groups and foreign populations. Rock art was likely meant to re-affirm their social and cognitive
structures/abilities – in other words, to stabilize extant cultural configurations that were under threat.
By the same token, but considering the peculiarities of cumulative cultural evolution, I understand the
emergence of the Franco-Cantabrian cave art as an expression of cultural acceleration. The grand-scale
application of latent symbolling abilities was triggered out as a reaction to the demands of an elaborate
constructed niche – in other words, to cope with biological (physiological/cognitive) losses inherent in self-
domestication.
Franco-Cantabrian cave art may also be understood as a cultural predisplacement, i.e., an early
application of extant figurative abilities (triggered out because of self-created stress) while, say, southern
African rock art exemplifies cultural postdisplacement, i.e., a late application of iconographic talent (caused
by external stress). As emphasized in the previous sections, stabilizing techniques may assume abstract
expressions when their objective is to re-establish a conceptual order (e.g. Batwa rock art), but also figurative
– when rock art is employed to re-affirm a social (behavioral) order (e.g. San rock art).

The perceptions of the ‘savage mind’ in anthropological and ethnographical works of the 19th century
seem to document a less restricted operational range of the contextual focus. As Chris Low (2004) observes,
“the cognitive capacities of natural people were considered to be ‘childish,’ with cause and effect randomly
sequenced in a world of probabilities that was also able to accommodate contradictions that were not rec-
ognized and ‘corrected,’ and in which the spiritual side was not a stranger to reality.”
To sum up, childish cognitive potentials were likely in demand 40 millennia ago in western Eurasia while,
in southern Africa, such cognitive abilities were still common with adults, as late as the 1970s.
At this point, some might argue that, in case that the authorship of Chauvet is acknowledged as that of
Neanderthals, the cave art could be interpreted – following my discussion of Bushman rock art – as the
product of ‘contact.’ With ‘contact,’ of course, meaning the arrival of AMHs in West Eurasia! But, as I have
repeatedly stressed, it was not the physical encounter with a foreign population that precipitated the emer-
gence of mid-Holocene San rock art, but rather the contact with a novel, ‘un-natural’ cultural environment.
I have also pointed out that an impressive number of transitional industries between the Mousterian and
Aurignacian traditions (Bednarik 2007) hint to the possibility that the Aurignacian was not imposed on Ne-
anderthals but developed by them.
In the case of isolated egalitarian hunters-gatherers, laboratory and and zoo chimps and bonobos, or the
hospitalized Jarawa boy, contact, i.e., an externally imposed cultural or environmental reality may trigger
out the massive and sudden application of latent but not relevant cognitive or behavioral abilities. However,
the ‘switch’ can also be self-initiated – as in the case of UP Eurasians. With them, cultural rhythm was
inflated: this was the time of the UP ‘singularity,’ when biology could not catch up with the pace dictated
by culture. The buffering between slow biological evolution and rapid cultural elaboration was effectuated
with the help of coping techniques (sensu Ellul 1964) which in this case, was the application of figurative
art, as discussed above. To stay with Ellul, the artificiality and rationality of the novel cultural environment
was likely to impact Aurignacians much stronger than mere physical contact with culturally not so different
newcomers. The Aurignacians did not become obsessed with their creative abilities only to cope with another
hominin group, but in order to cope with their own cultural construct which, after 20 millennia of cumulative
(horizontal) cultural evolution became ‘alien’ enough to demand buffering techniques. Indeed, Ellul (ibid.)
considers art – and the magic related to it – as the first technique.
IFIRARQ 16
62 Holocene Crossroads
According to Odling-Smee (2003), certain cultural environments have completely eliminated the natural
component and, in such an artificial context, selecting for maladaptive traits that only benefit survival in the
specific cultural environment – but affect negatively biological fitness – becomes the driving force of ‘cul-
tural evolution.’ Richerson and Boyd (2000) propose that the climatic changes occurring in the Pleistocene
may have provided the right environmental conditions for the onset of the cumulative dimension of culture.
Therefore, the cognitive side-effects mentioned above can be confidently associated with this specific mo-
dality of cultural evolution.
Indeed, Srinivasan et al. (2016) argue that schizophrenia emerged after humans diverged from Neander-
thals. That is, the origin of schizophrenia lies in gracilization: thus far, we already know that ‘divergence
from Neanderthals’ means the ‘gracilization of Neanderthals.’ As Frantz et al. (2015) and Tcharnov and
Horwitz (1991) have attracted the attention to, domestication – in this case self-domestication – leads, even-
tually, to speciation. Benítez-Burraco et al. (2017) do, indeed, suggest that schizophrenia and human self-
domestication are intricately related phenomena and that they occur in synchronicity. To stay with Benítez-
Burraco and colleagues (2016), they also float the idea that ‘‘schizophrenics are hyper-domesticated hu-
mans,’’ while ‘‘autists are undomesticated humans.’’
The Solutréan and Magdalenian art of western Europe is c. 20 millennia younger than that of Chauvet. Un-
fortunately, the cave art of the Aurignacian and the paintings of Lascaux and Altamira are mentioned in the
same breath and referred to as undisputable illustrations of a ‘fully maturized’ symbolling ability (e.g. Culley
2016, SGM p. 2). However, ongoing cumulative cultural evolution, physical gracilization and the emergence
of neurodegenerative syndromes – the ‘cultural products’ of these 20 millennia – must have left their imprints
on Magdalenian cave art which, far from being a communal coping technique with climatic change and
cognitive loss, should rather be understood as the display of a novel type of behavior that had evolved during
the said 20 millennia.
I argue that the cognitive abilities of children – who, during the Aurignacian, could still zoom-out beyond
the culturally-imposed limitations on adult cognition – were traded for the apparently similar ‘abilities’ dis-
played by schizophrenics. The natural ability to shift the contextual focus became corrupted to such an extent
that only cultural techniques would have approximated it – ranging from the use of hallucinogens to the
display of impressive shamanic techniques (as described by Witzel 2011). The external illustration of visions
acquired during culturally-induced hallucinations is very different from the experiences acquired in a natu-
rally defocused mental state. The illustration of defocused experiences characterizes Bushman trance, while
the illustration of culturally-biased visions is a peculiarity of Upper Paleolithic ‘shamanism.’ Both tech-
niques employ illustration as the means for externalization, but the experiences of ‘natural trance’ are shared
and are in the service of the community (Dowson 1994). Moreover, given that a large segment of the popu-
lation is made up of ‘shamans,’ (ibid., Deacon and Dowson 1996; Lewis-Williams 1988) those who experi-
ence ‘visions’ are not treated differently. Furthermore, leveling mechanisms (Woodburn 1982) see to it that
prestige and power cannot be accumulated. In contrast, the ‘special’ faculties of Magdalenian shamans be-
come means of accumulating prestige and status, ritual specialists become set apart and serve as role models
who also initiate novices – here we recognize cultural transmission based on biases listed by Henrich and
McElreath (2003).
Shamans become ritual specialists and monopolize ritual, which becomes their ‘field’ (which leads us,
again, back to Ellul: the first division of labor10 following the first technique, namely, ‘art.’
Spikins et al. (2018), in their article titled ‘Autistic traits in European Upper Paleolithic Art,’ suggest that
local processing bias played a role in the execution of the Chauvet, Lascaux and Altamira paintings. Unfor-
tunately, like many other researchers, they do not differentiate between Aurignacian paleoart and the much

later Magdalenian art. Their observations cannot be generalized and applied to the entire spectrum of Upper
Paleolithic cognitive manifestations in the Franco-Cantabrian region, but must be restricted to the Aurigna-
cian stage in which, indeed, child-like ‘undomesticated’ abilities (cf. Benítez-Burraco et al. 2016) were ap-
plied. However, ‘undomesticated’ in Aurignacian contexts is very different from what Spikins or Benítez-
Burraco call ‘autistic traits,’ or what Henrich and McElreath (2003) identify as ‘non-conformist biases.’ The
designations may be applied only to art-like productions in contemporary settings in which they acquire
negative connotations and are perceived as ‘aberrations’ from the prevalent psychological and/or cultural
norms. Having this in mind, Spikins’ assumption may be re-worded as undomesticated traits in rock art –
not only in the cave art of the European Aurignacian, but also in the rock art of ‘natural’ people. While, in
the European example, only children display such abilities, ‘undomesticated traits’ were successfully re-
tained by adults in egalitarian societies. As for Lascaux and Altamira, the interpretations that emphasize the
role of schizophrenic, i.e., ‘domesticated’ traits in their execution are, apparently, well grounded.

Conversely, in cumulative cultural orientations, the cognitive rigidity which was the aftermath of
specialization to a specific causal probability, resulted in the inevitable narrowing of the ‘cognitive ceiling’
and the loss of the ability to ‘escape’ the causal order that governs the cultural niche. Creativity was the
technique recurred to in order to access different causal dimensions, as described in the previous section.
However, the ‘alternate reality’ that was created could not escape the causal stencil to which cognitive
functioning became reduced and, instead of accommodating contradictory causal sequences, the ideated
models of reality became mere extensions of our own.
In Fig. 7 (above) I have inserted three images from a painting by Pippa Skotnes (see Groenwald 2008 and
explanations therein) which illustrate the differences between the vertical (a), median (b) and horizontal (c)
cognitive possibilities and limitations, as a function of the ability to shift the contextual focus to its associa-
tive end. Notice the two wheels depicted on the Boer pebble (c) and how they are substituted for the two
holes of the Bushman stone (a). While the Bushman has a natural ability to converge/diverge the contextual
focus to its both ends (the two holes), the ability of the Boer is blocked in the convergent end, i.e., stuck in
a single causal model of reality. Technological ‘innovation’ (the two wheels) compensate for the cognitive
loss.
Cognition becomes culturally-extended on the horizontal, with an accent on technologically-acquired,
stored and accessed information. Information is causally sequenced according to prevalent cultural trends
and perceived as ‘knowledge.’ Instruments must be developed in order to access information and external
storage capacity must also be technologically-expanded. Social learning becomes, similarly, based on the
transmission of technological know-how to access information and of the techniques devised for that (Fig.

Knowledge, in such cases, is not acquired in a zoomed-out associative mental state, but by an additional
zoom-in which can be effectuated only with instruments that complement our senses. Our technologically-
extended senses register only physical phenomena that can be detected by instruments devised in order to
model additional aspects of the same causal reality. Divergent mental states – art, religious fervor,
meditation, the use of hallucinogenes – are, likewise, mere buffering techniques, sensu Ellul (1964). The
‘alternate’ aspects of reality acquired with the help of such techniques cannot be experienced consciously
and thus, they remain phenomenal perceptions ‘banished’ by the cultural ‘self’ to a psychological dimension
known as the subconscious – which, itself, is a cultural product that reaches its maximal elaboration in
advanced stages of self-domestication.11

Managing the Risks of Cultural Evolution 65
CONCLUSIONS
The Middle/Upper Paleolithic transition is still perceived in mainstream paleoanthropology and archaeology
as the period when a ‘standard’ of anatomical, behavioral and cognitive ‘modernity’ was suddenly reached. Since
then, it is assumed that only cultural evolution defines the human condition. Unfortunately, most models of
cultural evolution strive to conform to this prevalent understanding. However, gene-culture coevolution theory
recognizes the obvious fact that for the last 50,000 years cultural evolution had a marked impact on our anatomy,
behavior and cognition. Moreover, far-reaching genetic changes were also detected, especially since the Neolithic
‘revolution.’ The influence of the climatic fluctuations and environmental instability of the Late Pleistocene on
the trajectory of cultural evolution is also considered in the model. Niche construction theory augments the picture
by placing the cultural process within a conceptual space that, in its turn, attracts adaptation to its realities and
thus affects anatomical, behavioral and cognitive changes. At first sight, the two complementary theories seem to
be the ‘ultimate word’ on culture. Indeed, if only the cumulative type of cultural evolution is considered, the tenets
of the theories model perfectly the mechanism and dynamics of the transformations that characterize the last 50
millennia of human evolution. But, unfortunately, gene-culture coevolution starts with the presumption that
technological innovation is the index of cultural change and that the ‘ratcheting’ of innovations becomes the main
‘goal’ of cultural evolution. This is accomplished by developing a certain degree of social complexity in which
social learning and the copying of cultural models – favored in cultural selection because of their skills, success
and prestige – become the main engines of cumulative cultural evolution. Small and isolated populations are, a
priori, perceived as ‘doomed.’ Innovations cannot be ratcheted in isolation and the ‘treadmill model’ takes effect,
in which the lack of demographic strength results in impaired social learning, loss and infidelity in copying, and
the absence of cultural models.
Contrary to the model proposed by gene-culture coevolution theory, the anthropological literature documents
small and isolated groups that have developed intricate social networking systems that are not necessarily based
on technological exchange and function only in low demographic settings, which is their very strength. Not only
that the parameters upon which biased cultural transmission is based in cumulative cultural evolution – prestige,
skills, success – are absent, but certain ‘leveling mechanisms’ take care that such parameters become inhibited
and thus, no cultural models can rise to prominence. These societies do not seem to be plagued by cultural ‘loss’
and, instead of hopelessly running the treadmill, they have developed egalitarian and, to an extent, ‘affluent’
societies. Minimal technological elaboration, small and flexible group size and the lack of the obsessive
preoccupation with the future are some of the characteristics of these generalized immediate-return hunters and
gatherers. The cultural evolution of such small and isolated groups does not rely on accumulation but, curiously,
on ‘reduction.’ Obviously, the Batek Negritos of Malaysia, the Mbuti Pygmies of the African rainforest, the !Kung
San of the Kalahari, and the Sandawe and Hadza of East Africa do not obey to the rules of gene-culture
coevolution, or dual inheritance theory (DIT).
The postulates of the theory introduce a paradox when the cultural evolution of these populations is studied. If
the onset of cumulative cultural evolution is dated to and equated with Late Pleistocene ‘modernity’ and presented
as the ‘natural choice’ of ‘moderns,’ then populations that do not follow such a model are either in a pre-modern
state or vulnerable to cultural ‘loss’ through the ‘treadmill effect.’
Hence, the problem of this fabled ‘modernity’ must be approached and reconsidered. Modernity has three
dimensions, namely: anatomical, cognitive and behavioral (the ‘ABC of modernity’):
(i) Anatomical modernity is a late phenomenon which was apparently not achieved until the Gravettian in
Europe and not until the Holocene in southern Africa. From the time of the emergence of H. sapiens and until the
abovementioned dates, robust archaic sapiens seems to have dominated the demographical map of the Old World.
(ii) Behavioral modernity is apparently a function of a biological process known as neoteny. Hominin evolution
seems to have been determined by neotenous processes. Neoteny manifests itself in its a) physiological aspects
(child-like, ‘pedomorphic’ appearance/the retention of juvenile traits in adulthood/a globular braincase/bulging
forehead, etc.), but also in its b) psychological side-effects (curiosity/playfulness/ creativity/sociability/reduced
aggressiveness and hierarchy).
The importance of psychological neoteny lies mostly in the reduction of hierarchical traits, which was also
observed with bonobos, a neotenized chimpanzee. The behavior of the peaceful and social bonobos is radically
different from that of the aggressive and hierarchically-organized chimpanzees.

66 Holocene Crossroads
(iii) Cognitive modernity did not arrive as a ‘big bang’ or a sudden ‘enlightenment’ during the Upper Paleolithic
but it was, apparently, a Middle Paleolithic phenomenon that coincided with a) marked encephalization; b) the
ability to shift at will the contextual focus between associative and analytic mental states; c) the emergence of the
ability to switch between systematic and trance tracking; d) the complementary use of mimetic skills and proto-
language; e) a surge in exogrammatic representation and f) ritual behavior, which is the simultaneous and
complementary application of all the aforementioned abilities, in a causally-prescribed and culturally-transmitted
sequence.
During the Late Pleistocene, a cognitively modern, but anatomically and behaviorally still archaic H. sapiens
populated the continents of the Old World and Australia. Cognitively, all these populations had similar abilities
whereas, anatomically, they seem to have displayed similarily robust features. Behaviorally, these robusts were
likely more hierarchically-organized and more aggressively-behaving than later Holocene populations.
In this paper, I have broached only the diametrically-opposed examples mentioned above: anatomically rugged,
cognitively specialized and behaviorally trans-egalitarian populations following cumulative cultural orientations
vs. anatomically pedomorphic, cognitively flexible and behaviorally egalitarian populations that follow a
reductive path in cultural evolution.
I have illustrated the development of these traits by tracing a set of coordinates which place hominin biological
evolution within a field defined by a vertical (o-y) and an horizontal (o-x) axis. In the biological field, vertical
tendencies are dominated by the retention of a state of ‘sufficient harmony’ with the environment, which is
accomplished through the reduction of specialized features, neoteny, and adaptive flexibility, whereas the
horizontal axis is dominated by tendencies toward the attainment of a state of ‘perfect harmony’ with the
environment, which leads to the cumulative acquisition of specialized features and adaptive rigidity.
On the o-y coordinate – which is obviously that which has exercised most influence on hominin evolution –
biological change appears to be always a step ahead of cultural elaboration. The latter may be simplistically
understood as a sort of ‘compensation’ for the biological reductions that characterize vertical evolution. Culture
also accommodates behavioral changes that occur as a result of biological reductions, i.e., the psychological side-
effects of neoteny: sociability, curiosity, playfulness. Cognitive modernity was apparently a biologically-
developed trait and the abovementioned ‘ritual behavior’ its immediate cultural aftermath. However, ritual
behavior cannot be classified as a purely cultural phenomenon and, because the etiology of its components is
rooted in biology, I have suggested that its emergence still represents a dot on a continuous biological-cultural
line. The origin of the differentiations listed above must therefore be sought in culture. In order to follow
developments in a markedly cultural setting, I have rotated the biological coordinates 90 degrees clockwise, and
in the complementary cultural field thus obtained, the vertical o’-y coordinate represents the continuation of the
biological-cultural line, whereas the o’-x’ vertical axis represents a novel cultural-biological trajectory. The same
tendencies toward specialization and generalization and similar mechanisms of accumulation vs. reduction
characterize the cultural field. However, on the vertical, culture adapts to biology and the biological-cultural
continuum is not disturbed whereas, on the horizontal, biology adapts to culture – and, therefore, the evolutionary
line is primarily cultural and biological developments are only shortcuts meant to catch up with and adapt to the
inflated rate of cultural change. In such a scenario, biologically maladaptive, but culturally beneficial traits may
appear and be selected for.
It would be convenient to conclude that cumulative and reductive cultural orientations parted paths at the
specific moment when our biological evolution came to a halt and cultural evolution took off, but this would be a
very rash and therefore, simplistic conclusion. Given the still marked continuum between biology and culture on
the vertical, and its obvious absence on the horizontal, I have suggested that cumulative cultural evolution
commenced as a punctuated ‘sudden jump’ long before a gradual transition to reductive orientations on the
vertical, in which a late cultural re-orientation was apparently preceded by a biological punctuation. Because the
cultural leap was effectuated at the very moment at which it was cognitively possible – i.e., at an advanced vertical
level in the biological field – and because the compensatory character of the constructed niche encouraged traits
that could become biologically maladaptive, I have floated the idea that this cultural sudden jump was taken
‘before time,’ at a moment when we were still not ‘ready’ for it, from an anatomical and behavioral point of view.
To fully grasp the implications of this suggestion, reductive orientations – in which, conversely, cultural steps
were taken only at a stage of morphological ‘readiness’ – were followed. Relying on southern African data relating
the prehistory of the San – which seems to apply to all immediate-return and egalitarian contexts – one can notice
G.F. Steiner
Managing the Risks of Cultural Evolution 67
that the divergence of the reductive and cumulative orientations did not occur from a ‘common cultural ancestor’
60 to 40 ka ago. Interestingly, 12 millennia ago, the ancestors of modern pedomorphic egalitarian hunters and
gatherers were still displaying markedly robust characteristics, with the notable exception of cranial morphology,
in which neotenous developments may already be observed. Thus, the psychological traits granted by neoteny
must have become crystalized during this period. These traits came to expression in the strategies adopted to
overcome the severe environmental changes brought about by the Last Glacial Maximum. As it can be inferred
from the archaeological record, groups isolated in the arid interior of southern Africa developed the Interior Wilton
industry, which is almost identical with the technological traditions of modern Bushmen. Curiously, this industry
has developed from a delayed-return background, which means that immediate-return strategies should be seen
as a cultural reduction, and not as an ancestral condition of ‘sophisticated’ delayed-return economies.
Behaviorally, the still robust ancestors of the San were likely more aggressive and hierarchical than their gentle
descendants but, cognitively, they must have been more flexible than their European contemporaries, who were
specializing to their own cultural constructs for over 50 millennia.
The fundamental difference between European and southern African developments was that – unlike in Europe
– the environmental stress of the LGM was not compensated for with cultural elaboration, but a biological
response was adopted. This could happen only at a moment when the terminal Pleistocene neotenal event
mentioned above – which was missed out by already heavily-gracilizing Europeans at that time – made these
populations ‘ready’ to undertake a reductive cultural step: a return to ‘primitive’ immediate-return subsistence
strategies. This was likely followed by the full expression of the cranial developments of the Late Pleistocene,
and a neotenal leap effectuated ‘in due time’ seems to have occurred. The psychological implications of this leap
became manifested in behavior, like reduced levels of competiveness, aggressiveness and hierarchy:
egalitarianism was developed, and its values were stabilized not according to the ratcheting techniques postulated
by gene-culture coevolution theoreticians, but by developing ‘leveling mechanisms.’ These are already cultural
products, just like the egalitarian societies that are regulated by them. The role fulfilled by leveling mechanisms
in culture is reminiscent of that played by neoteny in biology and, therefore, I have identified them as ‘cultural
neoteny.’ Cultural neoteny inhibits the development and accumulation of power and prestige and it also reduces
the possibility of people serving as cultural models, because of the egalitarian distribution of – and the egalitarian
access to – skills, resources, knowledge and experiences acquired in trance-like mental states. In such a cultural
configuration, the ‘holy cows’ of DIT become irrelevant. The treadmill effect becomes countered by the very
flexibility that characterizes these populations: small and mobile groups that may be joined and left without social
commitments, the dispersal of such groups over vast territories and the constant exchange of knowledge and
innovations through regional gift-exchange networks.
By comparing the biological-cultural continuum displayed by these Holocene immediate-return,
technologically backward, but socially egalitarian cultures to the artificiality of the cumulative, technologically
elaborate, but trans-egalitarian type of culture that has commenced at the MP/UP transition and became ratcheted
during the LGM, one will inevitably notice that the former is a natural extension of the hominin evolutionary line,
whereas the latter is an early split that has assumed an exclusively cultural dimension within which maladaptive
breeding preferences and cognitive specialization occur. Cultural heterochrony seems to be at play here, i.e., a
displacement in the timing of cultural evolution. Certain populations apparently developed first the biological base
that granted the behavioral traits upon which a novel social organization became elaborated, tens of millennia
after the ‘sudden jump’ into the cultural field effectuated by the anatomically and behaviorally still archaic
ancestors of populations whose present anatomy, behavior and cognitive peculiarities are the products of
cumulative cultural evolution and self-domestication.
The conclusions of this paper should not be seen as contradicting but, rather, as complementing the tenets of
dual inheritance theory which only seem to cover half of the spectrum of cultural evolution. On one hand, DIT
(gene-culture coevolution theory) strives to project the mechanisms of biological evolution on culture but, on the
other hand, it ignores the decisive role that neoteny seems to have played in our biological evolution. Therefore,
any theory of cultural evolution that does not include neoteny as a component is incomplete. In this paper, I have
attempted to correct this shortcoming by showing that neoteny has a cultural extension that should be
acknowledged and added to the variables upon which the equations of gene-culture coevolution theory are
constructed.

Stasis and change in Paleolithic times. A brief assessment of the Lower and Middle Paleolithic evolution-

Based on dual inheritance and macro-evolutionary models, the focus is on the conformist dimension of cultural trans-
mission and on the growth limits inherent in foragers’ eco-cultural niche building. The apparent lack of innovation
noticed in the Lower and Middle Paleolithic is also explored. The crucial role of demographical networks in the spread
and persistence of innovation is emphasized. Moreover, the marks of social inequality are depicted across the Euro-
pean mid Upper Paleolithic burial sample. Two points relevant to this essay are stressed: the symbolic segregation of
young children and the prevalence of an achieved individual status.

Managing the Risks of Cultural Evolution 79
The development of shared memories, beliefs, and norms is presented as being a fundamental characteristic of human
communities. These emergent outcomes are thought to occur owing to a dynamic system of information sharing and
memory updating, which fundamentally depends on communication. The propagation of ‘retrieval-induced forget-
ting’ is also followed and modeled. In this vein, the paper explores the influence of culturally-tainted ‘attitudes’ on
propagation. These findings are discussed in the context of the formation of collective memories.
This study provides insights into ancestral human neurobiology and suggests that Neanderthal-derived genetic vari-
ation is neurologically functional in contemporary populations.

Anarchic theory and the study of hunter-gatherers. The SAA Archaeological Record: The Magazine for
American Archaeology 17(1): 39-42.
‘Anarchaeology’ is defined as the study of how people throughout history have progressed and thrived with limited
government or with no government at all. Anarchic theory discusses the underlying philosophies that inform a view
of the world in which equality of power is seen as critical and alienation as antithetical to human happiness. Sanger
argues in favor of studying the techniques conducive to power equality with the same enthusiasm as we study the
‘evolution’ of inequality.
This work explores the social processes involved in technological innovation, particularly in relation to the Information
and Communications Technologies (ICTs). It is informed by 'Domestication Theory,’ namely: an approach in science,
technology and media studies that describes the processes by which innovations are 'tamed' or appropriated by their
users. First, innovations are integrated into everyday life and adapted to daily practices. Second, the users and their
environment change and adapt accordingly. Third, these adaptations feedback into innovation processes in industry,
shaping the next generation of technologies and services.
