Evolution is a fact as certain as the knowledge that the earth is not flat.
There are absolutely no assumptions necessary. It is not even a controversy any more. Actual scientists simply ignore the wilful ignorance of creationists, there is nothing more to be said about their superstitious nonsense.
Perry admits that he has never read a book that presents the scientific evidence for evolution in his entire life. This is absolutely typical of biblical creationists. He has posted dozens of times insulting and misrepresenting the rational side of the debate but never once has he attempted to actually refute the evidence.
Perry you are a primate. So are your parents. We have the fossils, we win. Get over it.
Edited to add - Is the best you can do to quote Richard Lewontin, the ideologically driven communist, 'Radical Science' disciple? FFS!
