A completely worthless "explanation." This would explain the opposite too. The entire Creation-ID-Post-Modern nexus has zero explanatory power precicely because "designed that way" can be said of anything. It is the agressive denial of knowledge.
The other problem is that there are not only shared mutations among primates, but shared viral genes incorporated into primate genomes. These are in the "non-coding" regions and thus seem not to be subject to selection pressure. There are those shared by chimps, gorillas, and humans but not by orang-utans. The chances of this happening are coecively less that 1^720.
Not much different than an agressive assumption of knowledge passed off in turn as fact. The ultimate cause of why things are the way they are is beyond the scope of peon evoltuionist "scientists." Sure, they can examine and point out what appear to be similar deficiencies in the universe, and so can creationists. But they can never adequately explain them.
