wiki did mention an increase in nutrition, especially in utero, so I guess i can buy that. But i just have a hard time buying that we are becoming more intelligent, and that it isn't simply that we have significant more experience at our hands.

I mean, how much mental activity could you do, when you didn't read, and you spent all day tending your fields. The potential might be there, but you aren't using your brain so you aren't pushing it to learn more.
