[Harmless Teddy Bear]

Some 2.5 million years ago, early humans survived on a paltry diet of plants.

Can I have something that resembles proof of that statement?

Harmless Teddy Bear: "Can I have something that resembles proof of that statement?"

Surely you know, there's no scientific "proof", but there is evidence and confirmed theory.
Evidence begins with the similarity of the oldest pre-human remains to those of chimpanzees, and the gradual increase over time in human-like features, along with fewer chimp-like features.
Since chimps are primarily plant-eaters, it's reasonable to suppose chimp-like pre-humans were also mostly plant-eaters.

Of course, the amount & type of meat they may have eaten at any given time is subject of study & debate.

That's science.

Nothing that you’d accept, I’m sure. Perhaps the author of the article would be able to help.
