Mongols

Genghis Khan Y chromosome

A Y-chromosomal lineage with several unusual features has been identified. It was found in 16 populations throughout a large region of Asia, stretching from the Pacific to the Caspian Sea, and was present at high frequency: approximately 8% of the men in this region carry it, and it thus makes up approximately 0.5% of the world total.

The pattern of variation within the lineage suggested that it originated in Mongolia approximately 1,000 years ago. Such a rapid spread cannot have occurred by chance; it must have been a result of selection.

The lineage is carried by likely male-line descendants of Genghis Khan, and it has been proposed that it has spread by a novel form of social selection resulting from their behavior. (12592608)
