Human Ancestors Were Nearly All Vegetarians- Scientific American

15. You are correct.

And Scientific American is good. But they publish a lot of science, especially new science, some of which does not hold up.

And teeth do indicate diet, at least that's what I've always studied and read. It is one of the main archaeological metrics we have of hominid history and ancestry. Teeth tell a huge story. Especially diet.

I haven't read the whole article yet (low BW here), but I am skeptical, as should everybody else. This is a bold claim. I would like to see how it pans out with other data and peer review.

Maybe hominids ate mostly veggies, and some meat. That would even be reasonable given what we know. We know from health studies that veggies are good.

But I suspect it's likely that hominids always ate some meat. And during the ice ages in Europe, their diet was substantially meat.

I just don't think that this one paper decides this once and for all. It looks to be an interesting take on the issue, but it will need time and review to decide this.
