Ancient humans ‘followed rains’
By Helen Briggs
Science reporter, BBC News
Prehistoric humans roamed the world’s largest desert for some 5,000 years, archaeologists have revealed.
When the landscape dried up about 7,000 years ago, there was a mass exodus to the Nile and other parts of Africa.
The close link between human settlement and climate has lessons for today, researchers report in Science.
“Even modern day conflicts such as Dafur [sic; Darfur] are caused by environmental degradation as it has been in the past,” Dr Stefan Kropelin of the University of Cologne, Germany, told the BBC News website. ….
Between about 14,000 and 13,000 years ago, the area was very dry.
But a drastic switch in environmental conditions some 10,500 years ago brought rain and monsoon-like conditions.
Nomadic human settlers moved in from the south, taking up residence beside rivers and lakes.
They were hunter-gatherers at first, living off plants and wild game.
Eventually they became more settled, domesticating cattle for the first time, and making intricate pottery.
Humid conditions prevailed until about 6,000 years ago, when the Sahara abruptly dried out.
There was then a gradual exodus of people to the Nile Valley and other parts of the African continent.
The domestication of cattle was invented in the Sahara in the humid phase and was then slowly pushed over the rest of Africa
“The Nile Valley was almost devoid of settlement until about exactly the time that the Egyptian Sahara was so dry people could not live there anymore,” Dr Kropelin told the BBC News website.
“People preferred to live on savannah land. Only when this wasn’t possible they migrated towards southern Sudan and the Nile.
“They brought all their know-how to the rest of the continent – the domestication of cattle was invented in the Sahara in the humid phase and was then slowly pushed over the rest of Africa.
“This Neolithic way of life, which still is a way of life in a sense; preservation of food for the dry season and many other such cultural elements, was introduced to central and southern Africa from the Sahara.”

Libya-Egypt, desertification and civilisation, can also be seen as part of a world wide process at that time.

By analysing a prehistoric site in the Libyan desert, a team of researchers has been able to establish that people in Saharan Africa were cultivating and storing wild cereals 10,000 years ago. In addition to revelations about early agricultural practices, there could be a lesson for the future, if global warming leads to a necessity for alternative crops: here.
The ritual human sacrifice that used to take place in many societies tended to promote class divisions, a new study suggests. The research, published online the journal Nature this week, concludes that the grisly practice played a role in sustaining and building social stratification: here.

Researchers at Washington State University and 13 other institutions have found that the arc of prehistory bends towards economic inequality. In the largest study of its kind, the researchers saw disparities in wealth mount with the rise of agriculture, specifically the domestication of plants and large animals, and increased social organization: here.
