I’m not sure this goes against @colewd’s hypothesis, actually.
His “created with identical genes” hypothesis is rather odd in that it allows each kind to be created with the same sequence, but at different times. So, for example, the “human” and “chimp” kinds might have been created with identical cytochrome c 6 mya, whereas the “chicken” kind was created with the same cytochrome c sequence but 12 mya. In that case, human and chimp cytochrome c would be twice as different from the chicken sequence than they are from one another.
The hypothesis is still falsified by the fact that these sequences form a nested hierarchy. But this particular piece of evidence doesn’t actually seem to contradict it.
