“Humans are herbivores!”-Except, not really.

So, Peta had done an article on their website (http://www.peta.org/living/food/natural-human-diet/)  proclaiming that humans are naturally herbivores.  Now I have no problems against vegetarians/vegans, but I do LOVE me some evolutionary biology, so I decided to go through the article and evaluate their claims that humans are naturally herbivores and not omnivores [See my previous blog, [here] where I examine the myriad of adaptations in humans to eat meat].

So, let’s get started, and see what evidence they present to support their claim.

Evolutionary adaptations to meat-eating in humans.

Abstract

This article reviews the some of the myriad of different genetic, physiological, morphological and nutritional adaptations in humans to eat meat.  These adaptations suggest human ancestors had a high reliance on meat and challenge the idea held by a substantial portion of the general public that humans are “naturally” herbivores and that our current meat-eating habit is facultative. On the contrary, the evidence suggests that humans are omnivores, being well equipped to eat substantial portions of animal tissue and have eaten meat since the dawn of our genus “Homo” millions of years ago.
