Human Ancestors Were Nearly All Vegetarians- Scientific American

8. Yeah, "paleo" really leans on misunderstandings about human origins.

I'm no expert- I took a few anthropology classes because I needed science credits and I'm awful at math- but what we can tell about human ancestors' diets from their teeth seems to suggest that moves toward specialization were not generally associated with long term survival. I suspect the early inclination to look at early humans as big hunters and meat eaters follows from two things: bones and such tend to leave long term traces while plant matter doesn't, so until we were able to look at chemical traces in teeth and such the evidence that was most obvious would be evidence of carnivorousness, and a cultural bias toward meat eating and hunting as manifestations of manliness that prevented looking at contrary evidence.
