Maybe ability to manipulate (thoughts/enviroment) has a huge say in primate->human evolution.
Well, duh! You think?
The size of the male penis, far larger than a gorilla's, and the size of the female breasts, far larger than necessary to feed offspring, are two of the most obvious results of sexual selection in humans. They're an evolutionary manifestation of the power of human thought. Who says size doesn't matter! To our ancestors it clearly mattered a lot.
I'm with Woody Allen who in the movie Zelig described how he split with Freud over whether only women could have penis envy.
