"Our development of intelligence genes "probably occurred in a
   world where every individual was exposed to nature's raw
   selective mechanisms on a daily basis," he said, but the same
   pressures do not apply today. " Eh. Nice theory but he's full of
   crap. It's idealizing a version of the myth of the "noble
   savage". It's a part of our cultural heritage to want to "return
   to a better time". Started in the 19th century among, well,
   anthropologists and popularized in the fiction of the day.
   There's peoples in areas of the world barely touched by
   civilization for the past 6000 years, except maybe for the last
   50 years or so, and they're NO DIFFERENT FROM US. He's full of
   shit. Sorry. There'd be evidence of "more intelligent genes"
   among the people who weren't in civilized contact and WERE still
   fighting. "Raw selective mechanisms"? What the heck is that?
   He's dreaming. Maybe I'm wrong. But it seems like a really
   romanticized view of an untestable past. That's also known as
   fables. I expect him to write a book that will get popular
   though, advocating a return-to-nature thing or people fighting
   in cages or something, I dunno tongue emoticon
