This article is arguing far beyond what the research showed:
yielded extensive archaeological evidence, including more than 20 layers of human occupation, fossilized animal bones, and preserved plant remains like seeds and fruits.
It showed we ate what was available. This isn’t new. We’ve always been classified as omnivores.
And plants were easier to catch.
Actually monkeys barely eat meat and they derived from mice which never eat meat so go back far enough and eventually you’ll see we didn’t start out as omnivores.
Conversely, as I just learned with surprise from an episode of The Ancients podcast, homo erectus seems to have been somewhat carnivorous for a period of a million or so years.
But sure, the primate family and related rodents and lagomorphs are generally herbivorous.
I believe its been a bunch of million years ago ‘we’ didn’t eat meay, there is a reason the beginning of human history started with hunters and gatherers. I don’t hink it was possible to live fully vegan if you weren’t wealthy until somewhere in the 20th century or so
