I find it hard top believe that we need both. People have populated (almost) every part of the world for centuries, and have vastly different diets wherever you go. Indians are vegetarian in general, while I imagine that Inuits traditionally ate pretty much anything but plants.

We should probably look at dominant human type and dominant diseases in populations skewed to a particular diet to see what the effects are. I would be interested in looking at strength/muscle/fat ratios, how does their tooth decay, % of population affected by frequent vegetable/fruit toxins and % of population affected by gout and similar illnesses caused by excessive meat consumption.
