Haplogroup C2 (M217) – the most numerous and widely dispersed C lineage – which is believed to have originated in Southwest/Central Asia, spread from there into Northern Asia and the Americas. C-M217 stretches longitudinally from Central Europe and Turkey, to the Wayuu people of Colombia and Venezuela, and latitudinally from the Athabaskan peoples of Alaska to Vietnam to the Malay Archipelago. Found at low concentrations in Eastern Europe, where it may be a legacy of the invasions/migrations of the Huns, Turks and/or Mongols during the Middle Ages. Found at especially high frequencies in Buryats, Daurs, Hazaras, Itelmens, Kalmyks, Koryaks, Manchus, Mongolians, Oroqens, and Sibes, with a moderate distribution among other Tungusic peoples, Koreans, Ainus, Nivkhs, Altaians, Tuvinians, Uzbeks, Han Chinese, Tujia, Hani, and Hui. The highest frequencies of Haplogroup C-M217 are found among the populations of Mongolia and Far East Russia, where it is the modal haplogroup. Haplogroup C-M217 is the only variety of Haplogroup C-M130 to be found among Native Americans, among whom it reaches its highest frequency in Na-Dené populations.
