There was a science tv show talking about the difference between a human brain and a chimp brain. It was amazing how well the chimp could remember things and do math!
(People flunked the same test, or I should say, did not score as highly).
So why are we running the world and chimps aren't. Chimps don't share/ pass on knowledge.
i wish I could remember the name of the show, it might have been Nova.
