DNA shows Sahara was green and populated 1,000 years ago

There was a time, between 12,000 and 5,000 years ago, when the Sahara was populated and covered in luxurious vegetation, according to a recent DNA study. The reconstruction was by a group of international biologists coordinated by Fulvio Cruciani from the Sapienza University of Rome in a study published in the Genome Biology journal.

To solve the puzzle of human evolution in the Sahara, the researchers used an innovative technique of genetic sequencing with which they analyzed over 3 million DNA letters of 104 individuals. They focused especially on the Y chromosome, passed down from fathers only to their sons, identifying almost 6,000 genetic variants, half of which had never previously been described. The data show that genetic characteristics of North African and sub-Saharan male population were shaped by migrations in ancient times.
