NEW discoveries hint humans did not evolve to trek out of Africa. That honour may belong to someone, or something, else.

THE idea goes that modern Homo sapiens — that’s us — evolved as an isolated community in Africa some 500,000 years ago. We then upped tools and trekked across the world, pushing Neanderthals aside as we went.

Turns out, that may not be quite right.

No, we’ve not found the imposing black monolith from the famous 2001: A Space Odyssey.

But some recent finds are no less significant.

“A few years ago, it seemed all too easy,” writes University of New South Wales Dr Darren Curnoe. “The matter was settled. Homo sapiens had evolved in the East African rift valley roughly 200,000 years ago and exited the mother continent to settle the remaining planet around 60,000 years ago.

“As someone who’s kept a keen eye on developments in, and indeed actively researching, our evolution, it’s clear to me that there’s something’s going on here. Change is in the wind!”

Part of this upset of established ideas is a new discovery in China.

On the cliff face in the north-central China state of Shangchen, a scattering of stone-age tools have been recovered.

They’re more than 2 million years old, their discoverers report in Nature.

Until now, the oldest known evidence of human ancestors — in this case Homo erectus — outside Africa was in Georgia, Eastern Europe. That dates back to about 1.85 million years — almost immediately after the species appeared in Africa.

But 96 stone blades, flakes and cores used to carve up antelope, deer and pigs in China’s Loess Plateau has upset the timeline.

They indicate hominins — the family that includes humans and our ancestors — got out of Africa at least a quarter of a million years earlier than thought, and occupied Shangchen on and off for more than 850,000 years.
Now, one argument goes, this indicates one of our more adventurous ancestors — Homo erectus — did not itself evolve in Africa.

Instead, Homo erectus is possibly an amalgam of diverse branches of earlier homominims that had already spread through Africa, Europe and Asia.

It’s an idea that emerges even as the origins of ourselves — Homo sapiens — falls under the spotlight.

Interesting... have argued against the "Out of Africa" model myself in the past.

I thought that babies were found in the pumpkin patch?

Perhaps we are both wrong and it was a pterodactyl
