Millions of men bear the genetic legacy of Genghis Khan, the famously fertile Mongolian ruler who died in 1227. Researchers have now recognized ten other men whose fecundity has left a lasting impression on present-day populations. The team's study1 points to sociopolitical factors that foster such lineages, but the identities of the men who left their genetic stamp remains unknown. The case for Genghis Khan’s genetic legacy is strong, if circumstantial. A 2003 paper2 led by Chris Tyler-Smith, an evolutionary geneticist now at the Wellcome Trust Sanger Institute in Hinxton, UK, discovered that 8% of men in 16 populations spanning Asia (and 0.5% of men worldwide) shared nearly identical Y-chromosome sequences. The variation that did exist in their DNA suggested that the lineage began around 1,000 years ago in Mongolia. #ChengisKhan #genetics #inheritance #encientDNA
