I am not aware of any evidence that “the “big bang” in cultural evolution that occured about 30,000 to 40,000 years ago” was caused by interbreeding with Neanderthals. That is probably bunk, IMHO. An entertaining story, but lacking in supporting evidence.
Where on Earth have you been for the last couple of days? : ] Hiding in a Croatian cave?
That being said, we currently have no reason to believe that this interbreeding had any phenotypic effects on the human lineage.
