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.
