No, there is not. There is debate as to how exactly it happened, but there is no debate that it happened. Do you understand the distinction? The *theory* of evolution explains the *fact* of evolution.<quoted text>
There is plenty of debating that "fact". Not just from people like me, either. Evolutionists argue & disprove each other all the time.
And WTF is an evolutionist? Are they like gravityers?
