The concept is exactly that - a concept. I could care less about who created it or what their political agenda is - basically it boils down to this :

Does anything exist which would constitute as a system that - if reduced - is non-functional and therefore not likely the product of a step-by-step mutation process?

Now, its pretty hard to make something of that nature anyway, since anything has to at some point or another be constructed step by step. But it does present some questions. I just can't fathom the number of iterations you have to go to get from the chimpanzee brain to the human brain.
