The scientific journal Science Advances recently published a study on the world’s third largest desert, which claimed that nearly 8,000 years ago the Sahara Desert was occupied by humans.This finding pushed forward some other scientists and their findings of the phenomenal history of that region which is in one way or another directly connected to our future.
Over 100 million years ago, the river as wide as the Danube flowing through the Sahara Desert. It was surrounded by dense forests, lakes, and waterfalls.That region in Sahara desert was hiding a 65-foot long limb bone of some plant-eating dinosaur. Other findings in that region include some remains of a crocodile the length of two double deckers, two inches long scales of some unknown fish, and rare dinosaur footprints near the Algerian border in south-east Morocco.
2. Retracing Steps
“The people who live in the Sahara Desert are mostly nomads. They move from place to place.”Although, the way of life was unique this time around. Rather than hunters and gatherers, cows agriculturists assumed control over the abandoned desert.
There are several underground water sources which are the remnants of those ancient times. They sometimes reach the surface and form oases.
4. Snowfall in Sahara
Snow is not a common thing for the largest part of Sahara Desert. It does fall on several mountain ranges regularly and that is it. However, in 1979 a snowstorm covered entire Algeria. That same thing happened in 2012.
5. Green Land
During that “green period” Sahara Desert was not a desert. It had forests, meadows, rivers, and lakes. where the desert area got more than 10 times the measure of rain it does today.Scientists found more than 30,000 petroglyphs of animals native to rivers in southeast Algeria in the Sahara region.
6. The Extinction
Around 8,000 years ago, something happened to this region and rain stopped. It must have gradually stopped and the waters started retreating deeper into the ground, and eventually, people started migrating to the south, towards the Atlas, and north towards Europe.
It is said that about 5,000 to 11,000 years ago the tribes of hunters and gatherers made Sahara desert their home, However, something extremely dangerous made them move to other regions in a search for food and shelter.
8. Source of Dust
The Sahara Desert, is presently the planet’s largest source of dust. This is because of the absence of vegetation and precipitation.
