Maybe we all came from Atlantis, now sunken in the Indian Ocean.

Paleo is the ideal neurodevelopmental diet- most regional differences in IQ
relate to omega 3 intake rather than genetics, and I think you'll find
inversely proportional to grain intake and grains are a lot worse than just
being Omega 3 deficient. The genes have not adapted. But really it's an ugly
subject as it rings up prejudice, and I'd rather people didn't discuss it.
