from the Sahara keyword:
Noyt questioning existence of a wet sahara; just the possibility that early herders made it a desert.
The world population which was in the low millions, had spread to all parts of the planet 11,000 years ago. There weren’t enough to affect the climate anywhere. They were lucky to have survived the 100 year long cold spells that occurred 10,000 and 8,000 years ago.
Killed a lot of mega fauna though. Lucky for us they were a tough group.
