One thing about evolutionists - scientific proof does not matter. All that matters is that their theory has to have an ancestor to man because the whole purpose of the theory is to deny that God is the Creator of man. However, as the Pope said, truth cannot deny truth and that is why the descent of man from monkeys keeps getting disproven by real science:
DNA clues to Neanderthals
Scientists have analysed the DNA of a third Neanderthal in an attempt to shed light on the genetic history of early humans. The results suggest that, like modern humans, Neanderthals expanded from a relatively small number of individuals.
And there is no evidence to indicate that Neanderthals interbred with modern humans, something that has always been a bone of contention among experts.
