were controlled by totally different genes in different creatures possessing
this pentadactyl structure. Evolutionary biologist William Fix describes
the collapse of the evolutionist thesis regarding pentadactylism in this
way:
The older textbooks on evolution make much of the idea of homology,
pointing out the obvious resemblances between the skeletons of the limbs of
different animals. Thus the `pentadactyl' [five bone] limb pattern is found in
the arm of a man, the wing of a bird, and flipper of a whale, and this is held
to indicate their common origin. Now if these various structures were
transmitted by the same gene couples, varied from time to time by
mutations and acted upon by environmental selection, the theory would
make good sense. Unfortunately this is not the case. Homologous organs
are now known to be produced by totally different gene complexes in the
different species. The concept of homology in terms of similar genes handed
on from a common ancestor has broken down. 284
On closer examination, William Fix is saying that evolutionist claims
regarding "pentadactylism homology" appeared in old textbooks, but that
the claims were abandoned after molecular evidence emerged. But, some
evolutionist sources still continue to put it forward as major evidence for
evolution.
The Invalidity of Molecular Homology
Evolutionists' advancement of homology as evidence for evolution is
invalid not only at the morphological level, but also at the molecular level.
Evolutionists say that the DNA codes, or the corresponding protein
structures, of different living species are similar, and that this similarity is
evidence that these living species have evolved from common ancestors,
or else from each other. For example, it is regularly stated in the
evolutionist literature that "there is a great similarity between the DNA of
a human and that of an ape," and this similarity is presented as a proof for
the evolutionist claim that there is an evolutionary relationship between
man and ape.
We must make it clear from the start that it is perfectly natural that
living creatures on the earth should possess very similar DNA structures.
Living things' basic life processes are the same, and since human beings
possess a living body, they cannot be expected to have a different DNA
