Genghis Khan

The paper suggests that the pattern of variation within the lineage is consistent with a hypothesis that it originated in Mongolia about 1,000 years ago. Such a spread would be too rapid to have occurred by genetic drift, and must therefore be the result of natural selection. The authors propose that the lineage is carried by likely male-line descendants of Genghis Khan, and that it has spread through social selection.
Vlad The Impaler
