Human beings
Hundreds of millions of years
:bugs-no:
The most recent common ancestor for humanity has been estimated at 1400 BC, and the point where we have no uncommon ancestors at 5300 BC. The only exceptions would be tiny populations of fully isolated peoples such as the North Sentinelese Islanders.
What does uncommon ancestor mean here? In 5300 BC there were no individuals that some modern humans but not all modern humans descend from?
I thought we left Africa around 70k years ago at the latest due to the Toba explosion?
