Ooh, I think I figured out how to quote "box" stuff finally! Learn something new every day.

I find this stuff fascinating. It only makes sense that humans, living for the vast majority of time in very disparate places, with very different diets, would develop or lose mutations to give them an adaptive advantage. Hopefully a continued study of genetics can help us begin to unravel some of these genetic differences. Of course we are so mixed up, unless we have a personalized genetic evaluation, the information may not help us determine the "ideal diet".
