I've been reading a few of Ian Tattersall's books ( Extinct Humans, The
Fossil Trail and Becoming Human) and have to wonder about the % of animal foods
some paleoanthropologists have drawn as their conclusion versus someone like
Cordain (larger amounts of animal foods).

Tattersall statesthat it is virtually certain that the bulk of the diet was
indeed vegetable foods (berries, fruits,seeds, tubers etc..) and he goes on to
say that a couple of specimans is not of
course a great statistical sample upon which to base statements about the
diet of an entire species.

How is someone like Cordain so sure?
