The importance of large prey animals during the Pleistocene and the implications of their extinction on the use of dietary ethnographic analogies

Estimates of the human trophic level and dietary quality during the Paleolithic are the basis for many hypotheses and interpretations regarding human evolution and behavior. We describe an additional factor that could have significantly influenced human evolution and behavior, the availability of large prey animals. Given the importance of large prey and the mounting evidence of the decline in its abundance throughout the Pleistocene, we question the reliability of past reconstructions of the human trophic level that were heavily based
