It is said that about 5,000 to 11,000 years ago the tribes of hunters and gatherers made Sahara desert their home, and they lived off on plants and animals.
The Sahar Desert receives only one to four inches of rainfall per year as per Jessica Tierney from the University of Arizona. The Sahara desert is 10 times drier now than its “green” period.
As per the examinations made by the specialists at the University of Arizona, the Sahara experienced a “green period” where the desert area got more than 10 times the measure of rain it does today.
The archaeologists claim although people possessed a large portion of Sahara amid the wet time frame. But around 8,000 years ago they gradually started to move out.
It could be stated that desert started drying due to the decrease in rainfall, which happens to be one of the sole reason why people moved from the Sahara region.
Strangely enough, the people inevitably returned to the Sahara Desert after the dry time frame started. Although, the way of life was unique this time around. Rather than hunters and gatherers, cows agriculturists assumed control over the abandoned desert.
