Ancient human genomes suggest three ancestral populations for present-day Europeans
We sequenced genomes from a [~]7,000 year old early farmer from Stuttgart in Germany, an [~]8,000 year old hunter-gatherer from Luxembourg, and seven [~]8,000 year old hunter-gatherers from southern Sweden. We analyzed these data together with other ancient genomes and 2,345 contemporary humans to show that the great majority of present-day Europeans derive from at least three highly differentiated populations: West European Hunter-Gatherers (WHG), who contributed ancestry to all Europeans but not to Near Easterners; Ancient North Eurasians (ANE), who were most closely related to Upper Paleolithic Siberians and contributed to both Europeans and Near Easterners; and Early European Farmers (EEF), who were mainly of Near Eastern origin but also harbored WHG-related ancestry. We model these populations deep relationships and show that EEF had [~]44% ancestry from a \"Basal Eurasian\" lineage that split prior to the diversification of all other non-African lineages.
