And Darryl, those studies just support the fact that our ancestors consumed root veggies....not that they consumed grains or legumes or any non-paleo food, or that they limited their intake of meat.
Also, evidence that diseases of civilization are gone when there is enough food to go around? I cannot remember this being covered in a SINGLE anthro class. No, agriculture generally equated to health problems, regardless of the individual circumstances.
Finally, in the last paragraph or so, you mention that you don't really believe that humans cannot eat grain without health issues, and that 10,000 years might be enoug to evolve out of it....but then you say that we must disregard the diets of the hunter gatherers the 30000 years before that, because we have not evolved enough! While I do dispute the dates you listed, please clarify your reasoning here....
