> Being truly tribal we would not be omnivores but carnivores?

I think you would hard-pressed to find a legitimate scientific source claiming
that humans are actually carnivores and not omnivores.  I know that Audette and
Cordain would never claim that.

For me, personally, the best evidence of what our truly natural diet should be
comes from watching other primates.  Nearly all of them eat some amount of
fruits and vegetables.
