randman,
There is nothing but argument from similarity here, and similarities can be explained by common mechanisms, common authorship, common material (laws of physics and chemistry), etc,...and still work if universal common descent were not true, and since it works just as good if universal common descent is not true, then thus far, you guys have not presented falsifiable theory.
So why doesn't the Chimpanzee use proteins in Krebs cycle (or any other metabolic process) that are most similar to a Yucca plant then? Or a jellyfish? A lion? It
could be this way, given the molecules are funtionally identical, yet the molecules involved are most similar to a human. Why would this be,
again, if it didn't need to be? After all, there are millions of species that allegedly share a common "authorship" with the chimp, aren't there?
Why do molecules consistently return a similar relationship when cladistics are applied?
