Moreover, the suggestion that humans started eating meat recently is patently ridiculous in the face of the material record. The nicest way I can put this is to strongly recommend spending some time with Wikipedia. A good starting point would be the stone tools page, in particular the section on the Acheulean industry: https://en.wikipedia.org/wiki/Stone_tool#Mode_II:_The_Acheul...

Chimps not only hunt, they over-hunt:

> The apes have killed and eaten so many red colobus monkeys, the population has fallen by 89% and they are having to find new prey

Don't believe me and the BBC? How about Jane Goodall?

> One of the earliest and most significant discoveries made by Jane Goodall was that chimpanzees hunt for and eat meat.

Bonobos hunt at the same rate as chimps:

And, again, early humans hunted:

> The diet of the earliest hominins was probably somewhat similar to the diet of modern chimpanzees: omnivorous, including large quantities of fruit, leaves, flowers, bark, insects and meat (e.g., Andrews & Martin 1991; Milton 1999; Watts 2008). Tooth morphology and dental microwear studies suggest that the diet of some hominins may have included hard food items such as seeds and nuts, and underground storage organs (USOs) such as roots and tubers (Jolly 1970; Peters & O'Brien 1981; Teaford & Ungar 2000; Luca et al. 2010). By at least 2.6 million years ago, a remarkable expansion in this diet started to occur; some hominins began incorporating meat and marrow from small to very large animals into their diet.
