Long-standing belief that meat-eating helped drive human evolution called into question
There’s a widespread belief that eating meat became much more common with the advent of big-brained Homo erectus
wo million years ago, based on increased archaeological evidence of meat-eating from that point.
But new research in Proceedings of the National Academy of Sciences has called that belief into question, suggesting that the numbers don’t quite add up.
when you quantitatively synthesize the data from numerous sites across eastern Africa to test this hypothesis
‘meat made us human’ evolutionary narrative starts to unravel.” SAYS Dr. Andrew Barr
They found that, once they’d accounted for variation in sampling over time, there was no evidence that meat-eating increased once Homo erectus appeared.
While there was an increase in marked animal bones after the advent of Homo erectus, this was likely because sites from this time period had been more extensively studied and sampled
