I think another myth about our brain is that Chimps share 99% of our DNA. I think other factors make us much more different.
Picture a Chimp playing Chopin but not very well. I don't think so. Does that one percent difference contain so much difference between our species? It seems bigger than 1%

We are actually called Homo Sapien Sapien. (Hominid who knows he will die) This might be another myth.
