Who were the Basal Eurasians?

We sequenced the genomes of a ∼7,000-year-old farmer from Germany and eight ∼8,000-year-old hunter-gatherers from Luxembourg and Sweden. We analysed these and other ancient genomes with 2,345 contemporary humans to show that most present-day Europeans derive from at least three highly differentiated populations: west European hunter-gatherers, who contributed ancestry to all Europeans but not to Near Easterners; ancient north Eurasians related to Upper Palaeolithic Siberians, who contributed to both Europeans and Near Easterners; and early European farmers, who were mainly of Near Eastern origin but also harboured west European hunter-gatherer related ancestry. We model these populations’ deep relationships and show that early European farmers had ∼44% ancestry from a ‘basal Eurasian’ population that split before the diversification of other non-African lineages.

Ancient human genomes suggest three ancestral populations for present-day Europeans

Basal-Eurasian is a hypothetical line of descent, which exists in greatest amount among ancient Near East individuals. Basal Eurasians may have been present in the Near East, as anatomically modern humans resided in the Levant approximately 100,000 years ago.
