occurrence and origin of being. The chapter lays the groundwork for subsequent
discussion in the book of the development of multicellular organisms from unicel-
lular ancestors and their evolutionary pathways for energy storage, cell-cell interac-
tion, and intra-tissue communication, for example.
The avenues and processes just mentioned required the involvement of two ele-
mental chemical species, calcium and phosphorus, for critical protection against
predation and as determinants to enhance metabolism, survival, and genetic varia-
tion. Calcium and phosphate ions and their solution and saturation character in an
aqueous environment as well as the fundamental physical-chemical principles gov-
erning mineralization are examined in Chapter 2, “The Enigma of Edith: Free
Energy, Nucleation, and the Formation of Mineral.” Here, these foundation stones
derived from investigations conducted in vitro in cell-free aqueous systems are
described to address homogeneous and heterogeneous nucleation theory and to
demonstrate that free energy changes induce calcium and phosphate ions to form
clusters which transition through an amorphous and other possible intermediate
phases to crystalline apatite during vertebrate mineralization. The chapter also high-
lights the nature of the putative precursor mineral phases as well as apatite and
structural aspects of bone and tooth mineral.
Chapter 3 provides an understanding of the “Form and Function of Tissues which
Undergo Mineralization,” and it details the origin, development, structure, and role
of bone, calcifying cartilage, dentin, cementum, and enamel in comprising the ver-
tebrate skeleton and dentition. In this regard, there is discussion of the origin of
bone and the interplay of osteogenic cells in the lateral and paraxial mesoderm in
association with cells derived from the neural crest to form the vertebrate skeleton.
With respect to the dental tissues, the interdependence between dentinogenesis and
amelogenesis during tooth development is considered. Another theme of this chap-
ter is how lineage tracing studies can be used to identify the origin and fate of osteo-
genic and chondrogenic cells in complex tissues like those residing in the epiphyseal
growth plate. Several principal genes, proteins, and other molecules involved in the
formation and mineralization of the respective tissues are introduced to establish the
basis for presentation of the topics of subsequent book chapters.
A powerful approach to determining how cells regulate mineralization is to eval-
uate the expression of genes which characterize mineralizing tissues. The literature
indicates that gene regulatory networks define critical stages of skeletogenesis and
tooth morphogenesis. For example, in bone-forming cells of the mineralizing deer
antler, the deletion of a single transcription factor (SOX9) causes changes in over a
thousand genes, transcription factors, enhancers, microRNAs, and long, noncoding
RNAs. This and other studies emphasize the importance in hard tissue formation of
a multitude of transcription factors which include RUNX2, SOX8/9, SMAD3, and
several others which target parathyroid hormone-related protein, WNT/β-catenin,
hedgehog proteins, members of the bone morphogenetic protein family, fibroblast
growth factor, and solute carrier proteins, all important to the critical control and
regulation of vertebrate mineralization. These and additional genes, transcription
factors, and targeted proteins are elaborated in Chapter 4, “Genes and Gene
Networks Regulating Mineralization,” to provide a background to the complexity of

the temporal, developmental, and tissue-specific events which comprise gene regu-
latory networks, systems promoting vertebrate skeletal and dental tissue formation
and mineralization.
The results of genomic and proteomic investigations into vertebrate mineraliza-
tion are fundamental, informative, and most important but, by themselves, do not
provide details concerning the mechanism(s) by which skeletal and dental cells
manage the massive amounts of calcium and phosphate ions required to build the
mineralized phases of vertebrate hard tissues. Chapter 5, “Calcium and Phosphate
Ion Uptake, Distribution, and Homeostasis in Cells of Vertebrate Mineralized
Tissues,” concerns mechanisms by which calcium and phosphate ions are controlled
and regulated during their entry into osteoblasts, odontoblasts, ameloblasts, and
other cells of hard tissues. Control and regulation of the ions are discussed in the
context of the formation of palisades of the cells (except for the cells of cartilage
and mineralizing entheses) linked by tight junctions which provide selective pas-
sage to the free flow of ions between the cells. Additionally, ion transport is described
through modulation by the membranes of the cells or, more precisely, by a host of
transmembrane channels, gates, and ion transporters and exchangers, which protect
the cells from large ionic shifts that would alter the activity of critical metabolic
pathways. Within the cells, the homeostasis of ions, particularly calcium, is detailed
in terms of their trafficking in association with specific cytosolic binding proteins
and their accumulation and/or storage in the endoplasmic reticulum, mitochondria,
endosomes, and other cellular membrane-invested constituents.
The secretion of calcium and phosphate ions from the cells of vertebrate mineral-
ized tissues is the subject of Chapter 6, “Calcium and Phosphate Ion Efflux from
Cells: The Roles of Matrix Vesicles, Extracellular Vesicles, and Other Membrane-
invested Transporters in Vertebrate Hard Tissue Mineralization.” In part, this chap-
ter addresses how mineral ions are packaged in the cells and transported to the
extracellular matrices of mineralized tissues. The details of these processes are dis-
cussed in the context of calcium ion release from mitochondrial and endoplasmic
reticulum stores for association with vesicles derived from the endosomal and
autophagic pathways. These latter two important intracellular systems are further
considered with respect to their roles in forming a variety of organelles carrying and
transiting proteins, lipids, and other molecules or ions or ion clusters throughout the
cells or toward the cellular plasma membrane. Finally, the numerous organelles,
including lysosomes, autophagosomes, acidocalcisomes, exosomes, microvesicles,
matrix vesicles, and several other membrane-enclosed transporters, are addressed
functionally to ensure cell survival through autophagy and to contribute to extracel-
lular mineralization through downstream endosomal pathway transitions.
Expression of genes leads to the synthesis and secretion of their counterpart pro-
teins and other molecules. Of these, the most important and highly abundant is the
family of collagens. Several collagen types associate with mineral ions to form ver-
tebrate mineralized tissues. Chapter 7, “Collagen-based Mineralization of Bones,
Teeth, and Other Vertebrate Skeletal Tissues,” describes the character of collagen,
its structure, composition, assembly, and interaction with mineral ions based on the
predominant type I collagen species in bone, dentin, cementum, and avian tendon.
viii Prologue
In a related manner, the nature of type X collagen is also detailed in its role in the
mineralization of epiphyseal cartilage. Completing this chapter is current under-
standing of the means by which non-collagenous proteins such as bone sialoprotein,
osteopontin, and osteocalcin may mediate extracellular mineralization as well as
recent results demonstrating an extensive, complex nanochannel network proposed
to provide transport and delivery of ions and small molecules throughout the extra-
cellular matrices of calcified cartilage and bone.
Bone sialoprotein, osteopontin, and osteocalcin are but three of an extensive
number of non-collagenous proteins which participate in the mineralization of ver-
tebrate hard tissues. Chapter 8, “The Role of Non-collagenous Proteins and Other
Matrix Molecules in Vertebrate Mineralization,” expands details and functional
descriptions of such constituents, including the family of SIBLINGS (Small
Integrin-Binding Ligand, N-Linked Glycoproteins), SLRPS (Small Leucine-Rich
Repeat Proteoglycans), matricellular proteins, and several additional proteoglycans
and proteins comprising the skeletal and dental tissues, including enamel. In this
instance, these matrix molecules participate in multiple, specific interactions which
lead to comprehensive oversight and careful and strict regulation, control and coor-
dination of extracellular matrix formation and deposition of mineral in vertebrate
tissues.
The two closing chapters of this book consider the importance of systemic as
well as local agents in the control of apatite development in the extracellular matrix
in vertebrate tissues while preventing aberrant mineral precipitation. Such a need is
met by the activities of inhibitory molecules which bind mineral ions or their clus-
ters or block mineral deposition in the tissue fluid which is normally supersaturated
in both calcium and phosphate ions. Chapter 9, “Local and Systemic Regulation of
Mineralization: Role of Coupling Factors, Pyrophosphate, Polyphosphates, Vitamin
D, Fetuin, Matrix Gla Protein, and Osteopontin,” details the structure, secretion, and
role of certain of these potent inhibitors and the manner by which they may regulate
cellular function and interaction and ultimately mineral deposition in vertebrate
hard tissues. Chapter 10, “Aberrant Mineral Deposition in Soft and Hard Tissues,”
describes several disorders of mineralization which occur in soft as well as hard tis-
sues, including dystrophic mineralization, heterotopic ossification, microcalcifica-
tions associated with breast cancer, and defective mineralization resulting from
mutations in extracellular matrix proteins. These pathologies are detailed in terms
of their putative or known etiologies; their systemic and/or local effects on critical
genes, transcription factors, hormones and other proteins which control the avail-
ability and access of calcium and phosphate ions to cells and extracellular matrices;
and their implications that mineralization is fundamentally driven by cellular, rather
than extracellular, processes.
The ten book chapters described briefly above constitute a continuous thread of
information which binds together the science of vertebrate mineralization from its
evolutionary origins and physical-chemical principles to its presence in both healthy
and diseased human tissues. Included in the chapters are insights into gene expres-
sion and protein synthesis and secretion; ion and protein transit into, through and
out of cells; major constituent molecules and their extracellular interactions; and
Prologue ix
If we two authors had realized at the outset that writing a book about the deposition
of mineral in vertebrate tissues would be so daunting, this task might not have been
undertaken. The research literature on the subject of skeletal and dental tissue min-
eralization is enormous and encompasses topics as varied as the physical chemistry
of dilute solutions, the function of the endomembranous system of the cells of bone
and cartilage, and the enigma of the mineralization activity of the cells which form
dental enamel. Discovery and publication in these and other related areas con-
tinue daily.
The idea for a book devoted solely to understanding the mechanisms of normal
and aberrant mineralization in vertebrates originated from extended discussions
between one of the authors (Dr. Shapiro) and his colleague and friend at the
University of Pennsylvania, Dr. Ellis Golub. These two individuals spent hours
upon hours considering topics which should be included in a book of this type. With
the unfortunate death of Dr. Golub, Dr. Shapiro was able to persuade Dr. William
Landis, who has made important contributions to molecular biological and struc-
tural aspects of the mineralization process, to assume an authorship role. The two of
us have compiled what we believe is a detailed, comprehensive, and informative
work on the process of vertebrate mineralization, to be used by anyone interested in
this field fundamentally important to human well-being and life survival.
A major source of inspiration for the book has been the research and writings of
Drs. William and Margaret Neuman. Over 60 years ago, these two scientists were
the first to describe the mineralization event on the basis of physical chemistry and
metabolism while at the same time suggesting that hydroxyapatite may have been a
mineral associated with the origin of life itself. For these reasons and for their pro-
found insight into the role and overarching importance of vertebrate mineralization,
the authors dedicate this book to Drs. William and Margaret Neuman.
The authors have several additional personal dedications to make as the proper
acknowledgment of forbearance, time, faith, infinite tolerance, good humor, and
other qualities which were essential for completion of this work. Dr. Shapiro dedi-
cates this book to Dr. Joan Poliner Shapiro, whose laughter fills his days with joy,
and to Dr. Susan Hope Shapiro and Mr. Mark Edlitz, who, along with his grand-
child, Jessie, provide love and caring which permeates his very soul. Dr. Landis
dedicates this book to Ms. Jane Hogan Landis for being the ultimate support and
guiding light to her husband over the duration of far more years of writing than she

and he ever imagined. Both authors thank the late Dr. Ellis Golub for his friendship
and contributions to the science of mineralization and Dr. Russell Neuman for his
kindness in providing the images of his parents appearing in Chapter 1.
A book of this detailed and comprehensive nature could not have been written
without the bedrock foundation of nearly uncountable journal articles and chapters
of other books and publications which constitute the fields of both vertebrate and
invertebrate mineralization. The two authors here have relied heavily on these innu-
merable literature entries. To begin an attempt of gratitude, the authors, first and
foremost, would quote Mr. Leonard Cohen, the noted poet, musician and philoso-
pher, who said, “There is a crack in everything, that’s how the light gets in.” In this
regard, an army of scientists and scholars has helped enlarge the crack and enlight-
ened our knowledge of tissue mineralization. Their published studies are cited in the
reference lists at the end of each of the chapters. In the same vein, the authors must
also apologize to the host of other investigators whose work has significantly
expanded the knowledge of mineralization, but whose findings could not be included
in the bibliography because of limitations in the space for each book chapter.
Additionally, this book would not have been completed without the enormously
generous and knowledgeable contributions of a great many other colleagues, who
took the burden and trouble to read and question or comment upon sections of the
chapters and to discuss points of concern and provide expertise and their final reso-
lution. The personal insights, time, and efforts of these friends and collaborators are
also deeply appreciated and gratefully acknowledged by the authors of this book.

kindness, collegiality, collaboration, friendship, and extensive training and educa-
tion in orthopedic research and scientific study in general he received from the late
Melvin J. Glimcher, M.D., Ph.D., in the Department of Orthopedic Surgery at the
Children’s Hospital and Harvard Medical School, Boston, MA, USA. Additionally,
Dr. Landis is grateful to the late Dennis S. Weiner, M.D., from the Department of
Orthopedic Surgery at the Akron Children’s Hospital, Akron, OH, USA, and to

Surgery, Kindai University, Osaka, Japan, each of whom contributed to extensive
clinical orthopedic insight into mineralization and to long-standing research col-
laboration and publication. Lastly, the authors thank their publisher, Springer, for
immense patience in repeatedly extending the deadline for publication of this book.
In writing these book chapters, the authors have brought together findings from
an extraordinary number of investigations focusing on processes by which skeletal
and dental cells manage the transport of ions forming apatite mineral in the verte-
brate hard tissues of bone, calcifying cartilage and tendon, dentin, cementum, and
enamel. The book has two principal themes, the first, to record in each of its chap-
ters salient observations concerning key aspects of the structure, composition,
molecular and cell biology, and genomic, proteomic, endocrinal, metabolic, and
environmental nature of the vertebrate mineralized tissues; and the second, to use
information obtained from these and other studies to relate cellular activities to the
physical-chemical events which result in nucleation, growth, and development of
apatite. In other words, the book attempts to explain how biological mineral is
formed, intertwined with the specific organic extracellular matrix of each of the
hard tissues.
A major objective of the book is its search for a unifying mechanism underlying
the means by which mineralization takes place across the diverse spectrum of the
vertebrate hard tissues. Like many other scientific quests, complexities breed com-
plexities and simplistic answers to questions and problems are seldom acceptable.
Nevertheless, based on new studies utilizing state-of-the-art techniques, it is now
plausible to consider certain generalized features of vertebrate (as well as inverte-
brate) mineralization: (1) Cells may form tissue palisades (osteoblasts in bone,
odontoblasts in dentin, and ameloblasts in enamel, for instance) linked by tight
junctions to create barriers which regulate the free flow of ions from the systemic
circulation to the mineralization front; (2) there is strict regulation of ions through-
out their trafficking intracellularly as they are secreted into the extracellular matrix
and localized to form the mineralizing front; and (3) the formation of apatite, that is

xxii About the Authors
An mRNA strand with strings of codons is a relatively small and simple molecule possessing
limited storage capacity. It can store small amounts of genetic information; the capability of
a ribozyme as an enzyme is severely limited. However, this catalytic deficiency is compen-
sated by a variety of enzymes that are available in the hydrothermal vent environment. The
short life of mRNA makes the protocell very responsive to changing conditions in the environ-
ment. Later, more durable DNA would emerge to become the molecule of choice for the large
storage of genetic information regarding protein synthesis, replacing mRNA from its main
function. The new generation of mRNA is created by the transcription of DNA. mRNA becomes
a daughter of DNA to carry out its specific instruction of translation and protein synthesis. [1]

Gene/Protein Nomenclature
Symbols for genes are written in uppercase and italicized (for example, COLIV),
whereas symbols for proteins are given in uppercase but not italicized (for example,
COLIV). For simplicity, the chapter does not distinguish between the same genes/
proteins found in animals and humans.
Many prominent scholars believe that life emerged on Earth approximately 4.5 bil-
lion years ago in an atmosphere thought to be rich in carbon dioxide and nitrogen,
possibly containing low levels of methane and other gases, and one in which oxygen
had yet to make an appearance [2]. At this very early, prebiotic period in Earth his-
tory, the slightly acidic Hadean-Archean Ocean covered much of the world, with
limited land mass above sea level. Under these conditions, seemingly random
chemical processes culminated to generate the “protocell,” a self-replicating and
energy-generating structure, the forerunner of a living cell.
Although events which preceded the appearance of life on Earth are of consid-
erable chemical and biological interest, on first reflection they seem far removed
from the mechanism of mineralization of bones and teeth. However, a role for
minerals like apatite and calcite in prebiotic chemistry was enunciated clearly
more than 50 years ago by the founders of skeletal chemistry, William and
Margaret Neuman, when they commented, “In the beginning, there was apatite”
(see Box 1.1 for additional information) [3]. In retrospect, this intriguing state-
ment was somewhat naive as apatite is only a minor component of some rocks,
and the prebiotic Earth contained an abundance of other minerals such as olivine,
pyroxene, calcite, silica, clays, and pyrite, many of which were more reactive than
apatite. Moreover, from a biological viewpoint, apatite is just one among many
minerals associated with the mineralization of both pro- and eukaryotic organ-
isms. In this introductory context, the goal of this first book chapter is to bring
together some ideas about the origins of life and the catalyzing role of mineral in
the formation of critical molecules required for the initiation and subsequent evo-
lution of the skeletal tissues.
Over 60 years ago, Stanley Miller, a graduate student in the laboratory of Harold
Urey at the University of Chicago, devised an experimental approach to understand-
ing how life originated on Earth. Miller hypothesized that the atmosphere of the

was chair of the Department of Radiation Biology and Biophysics at the
University of Rochester, Rochester, NY. He worked with the Atomic Energy
Commission and was particularly concerned with radiation protection. In
1965, he reported on the effects of space flight on the musculoskeletal system
of the Gemini 7 astronauts. This work catalyzed his interest in the biochemis-
try of bone, especially mechanisms of action of osteoblasts in mediating the
mineralization process of vertebrates. He was the recipient of many honors,
including the Eli Lilly award, the Claude Bernard Medal, and the Kappa Delta
research award from the American Academy of Orthopedic Surgeons. In
1958, together with his wife, Dr. Margaret Neuman, he co-authored the book,
The Chemical Dynamics of Bone Mineral. While working as a biochemist in
her own right, Margaret Neuman performed important work concerning the
cell biology of bone, especially in relation to bone-seeking radioactive ele-
ments. Many of her papers were directed toward understanding mechanisms
controlling bone cell function, factors regulating bone-blood homeostasis,
and the origin of life. Images are a gift from Russell Neuman, Ph.D.
1.2 Chemical Syntheses on Bioactive Surfaces 5
primitive Earth could, under appropriate conditions, support the abiogenic (chemi-
cal) synthesis of organic molecules required for life [4]. In other words, the forma-
tion de novo of compounds like sugars and amino acids would provide the building
blocks for the eventual creation of primitive living organisms. To test his hypothesis,
Miller set up a circulating water system in a gaseous environment which was thought
to mimic that of the primitive Earth: methane, ammonia, and hydrogen. The system
was then perturbed by periodic electrical discharges into the gaseous milieu. After a
week, he reported that the water became turbid as a consequence of trace amounts
of the amino acids, glycine, α-alanine, β-alanine, and aspartic acid among many
other organic molecules. The results of this experiment directly supported the con-
cept that organic syntheses were possible from very simple agents. Additionally,
Miller found that the amino acids were bound to silica particles released from the
glass used for the experiment [4]. This latter observation suggested for the first time
that the surface chemistry of a mineral, silica in this case, might be involved in reac-
tions leading to the synthesis of biogenic molecules, and the finding confirmed a
number of related ideas which had been propounded earlier. Such mineral–organic
interfacial events in the origins of life have been reviewed [5].
Expanding this catalysis concept further, this chapter presents views detailing
how rock surfaces and chemicals percolating from rocks, the gases in the changing
atmosphere, molecular constituents of tidal pools and hydrothermal vents, as well
as sources of external energy conspired to initiate life. Such ideas rest on accumulat-
ing evidence that complex organic molecules, especially self-replicating ribonucleic
acid (RNA) with enzymatic properties, could originate in the primitive gaseous
Earth environment. It is important to note that this hypothesis is only one consider-
ation for the origin of life, and alternative proposals, such as “Metabolism-first” and
the “RNA-peptide coevolution world,” also exist.
The present chapter focuses on the RNA World hypothesis, in which the func-
tions of RNA molecules relate directly to the most basic needs of life, protein syn-
thesis and reproduction. In addition, the chapter considers the importance of
molecular barriers to separate the contents of the “protocell” from the external aque-
ous environment. A barrier function could be achieved by the self-assembly of
hydrophobic compounds to form membranes, an action which also provides a
mechanism by which metabolic energy could be generated by a chemiosmotic gra-
dient. Finally, although little is known of events which convert the non-vital proto-
cell into a living tissue, the chapter will examine the most primitive organisms in the
fossil record and speculate on means which may have contributed to the evolution
of bones and teeth.
In the natural world, the energy required for the type of abiotic chemical synthe-
ses mentioned above as occurring on mineral surfaces could come from a number
of sources. These would include thermal changes, ultraviolet (UV) light, electri-
cal energy, and ocean waves. Volcanic activity would also provide heat for chem-
ical reactions, and the generation of rocks like basalt, most prominently, could

Fig. 1.1 Schematic of mechanisms by which charged ions and molecules may be bound to a
mineral surface. Top panel: Interactions between charged ions and an apatitic surface. Depending
on the plane of section, apatite may present a net positive or net negative charged surface. Shown
here is a surface of net negative charge (attributable to predominantly phosphate or hydroxyl ions)
which binds ions of opposite (positive) charge. In this manner, a double layer of charged ions is
formed on the mineral surface. Bottom panel: Formation of a self-assembled monolayer on a min-
eral surface. The mineral surface can be naive, coated, or functionalized with protein. In the case
of a surface functionalized with receptor molecules, ligand molecules may bind to receptors. The
process of ligand–receptor binding leads to formation of domains of ligand molecules which may
then interact with each other to develop cross-links and intermolecular bridges. Such structures
stabilize the ligand molecules and promote their alignment and orientation, for example, in this
self-assembled monolayer on the mineral surface
While the significance of the prebiotic steps discussed above is still energetically
debated, the beach and tidal mechanisms described here emphasize a key concept:
mineral serves to direct and even participate in critical molecular events. The most
obvious development of this scenario is that simple amino acids would be present
among the chemical species synthesized and these could then develop bonds to
form peptides and even proteins. Conventionally, these biological catalysts promote
biochemical reactions which often lead to the synthesis of complex metabolic inter-
mediates and molecules like deoxyribonucleic acid (DNA) and RNA. While this
finding is valid for living cells, unanswered questions remain as to how these protein
8 1 In the Beginning
catalysts may be formed and how they can replicate in the abiotic world. Stated
otherwise, these proteins, once formed, would need to synthesize copies of them-
selves for subsequent generations. Of course, such a situation also raises a more
critical concern of whether apatite could be involved in any way with the genesis of
replicative molecules. This issue is discussed in the next section of this chapter.
Besides the volcanic rocks and minerals noted above, additional organic com-
pounds may have been delivered to the Earth by comets and asteroids. Infrared
spectra generated by the National Aeronautics and Space Administration (NASA)
Dawn spacecraft as it journeyed through the asteroid belt for over 11 years and
orbited Ceres, a dwarf planet which lies between Mars and Jupiter, lend support to
this possibility. Analysis of visible and infrared spectra showed the presence of
long-chain organic (aliphatic) compounds as well as ammonia-containing hydrated
minerals and organic molecules [14]. Thus, organic compounds liberated from plan-
etary detritus, over the eons of time, could generate the molecules and macromole-
cules associated with self-replication and life.
As an aside, meteorites have been shown to contain a rich mix of organic com-
pounds, in particular mono- and di-carboxylic acids, ribose, and even amino acids
[15]. Furthermore, carbonaceous chondrites contain carboxylic acids, amino acids,
hydroxy acids, sulfonic acids, phosphonic acids, and poly-hydroxy compounds [16,
17]. All these compounds are basic building blocks of more complex tissue macro-
molecules. One particular meteorite, the Murchison meteorite, contained a mixture
of chirally right- and left-handed amino acids, with an excess of left over right [18].
This finding is of considerable interest as the amino acid constituents of proteins of
living organisms are predominantly left-handed. One explanation for this homochi-
rality is that minerals like calcite and quartz are chiral-selective [19, 20]. Hazen and
Sholl commented that, “Minerals provide Earth’s most chirally biased environ-
ments, and thus may represent the most likely loci for prebiotic chiral selection and
amplification” [19].
Minerals, then, whether terrestrial or extraterrestrial, have a number of functions
related to the origin of life. They provide a surface for adsorption and concentration
of organic compounds and inorganic ions; they afford a surface for chemical reac-
tions; they are a source of chemical reagents; and, for some minerals, they possess
a chirality which dictates structural features of the adsorbed reagent. This multitude
of roles raises the question as to whether minerals enhance reactions leading to the
synthesis of more complex molecules, especially those associated with membrane
function, replication, and information storage.
One of the tenets of the origin of life is the need to generate and concentrate simple
organic molecules. Subsequently, these molecules could be used to build a more
complex information-carrying molecule which could also serve as a chemical
