It seems the inspiration for this reconstruction was based upon a single piece of bone less than 3cm long which Alhberg found while sifting through bone fragments in a museum drawer. That a single bone or bone fragment can ignite the imagination of an evolutionist to imagine an entire creature which is presumedly evidence of evolutionary transition brings Nebraska Man to mind. Ahlber's fossil reconstruction of Icthyostega seems to be highly imaginative but not scientific because it does not conform to the known skeletal features of Icthyostegids and other fossil vertebrates of similar homology. I debated this matter with Mr. Ahlberg, but was not able to get straight answers from him about how his reconstruction is scientifically sound. Evolutionist have made much effort to marry the earth's fossil record of life with Darwinian theory. The proposed transition from the fossils of Celocanth, Sauripteris, Osteolepis, Panderichthys. Eusthenopteron, and Tiktaalik to Ichthyostega, especially Ahlberg's reconstruction, requires the transition of features which is not apparent in these fossils. Such transition would require countless changes to anatomy. Amongst the major transitions necessary but which are not present in any fossil are: 1) transition of the rib cage of Osteichthyes (bony fishes) to the bicipital ribs of amphibian tetrapods-development of tuberculum and capitulum in the ribs and parapophyses and diapophysis in the vertebrae 2) transition of the barrel-shaped rib cage of Ichthyostegids to one that is congested and heavily overlapping 3) migration of the shoulder girdle (Clavicle, Acromion, and Scapula) of Osteichthyes to that of Ichthyostegids 4) increase in rigidity of the spine and ribs from fish to Icthyostega, then to greater lateral flexion of the spine and ribs of reptiles 5) transition of lobe fins into limbs with digits 6) gradual dissapearance of ray fins 7) disappearance of gills and appearance of lungs 8) rearangement of caudal and sacral vertabrae 9) transition of "ashtray-shaped" vertabrae to "hokey-puck" shaped vertabrae It is quite interesting that so many prominent evolutionist scientists have acknowledged in their own books that the fossil record of life does not possess fossils which are clearly transitional, and that species appear fully-formed without intermediates. It seems that when evolutionists create works intended for their peers, they admit transitional forms are not known, but when speaking to the public, suddenly transitional forms are abundant. The lineage proposed by evolutionist scientists between fishes and tetrapods centers upon the species Eusthenopteron, Panderichthys, Tiktallik Rosea, Acanthostega, and Icthyostega. Unarguably, Eusthenopteron, Pandericthys, and Tiktaalik are fish. The transition of fish to amphibian tetrapods would require an intermediate form which crawls upon it's stomach on land but is able to swim well. While the morphology of Acanthostega seems to fit this need, it appears that the creature is simply a giant salamander which evolutionists have given a different name and placed in their imagined lineage to fill a critical gap.

Accruing phenotypic changes result in new genotypes (a distinguishable variety of a species). Accruing genotypic changes ultimately result in the arival of a fundamentally different kind of organism.
