TL;DR: It is shown 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; and early European farmers, who were mainly of Near Eastern origin but also harboured west Europeanhunter-gatherer related ancestry.

TL;DR: The authors showed that most present-day Europeans derive from at least three highly differentiated populations: west European hunter-gatherers, 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 hunters-gatherer related ancestry.

TL;DR: In this paper, a new approach harnesses the exponential decay of admixture-induced linkage disequilibrium (LD) as a function of genetic distance, which can be used to infer mixture proportions as well as dates with fewer constraints on reference populations.

TL;DR: It is shown that Steppe ancestry then integrated further south in the first half of the second millennium BCE, contributing up to 30% of the ancestry of modern groups in South Asia, supporting the idea that the archaeologically documented dispersal of domesticates was accompanied by the spread of people from multiple centers of domestication.

TL;DR: A new weighted LD statistic is presented that can be used to infer mixture proportions as well as dates with fewer constraints on reference populations than previous methods and can uncover phylogenetic relationships among populations by comparing weighted LD curves obtained using a suite of references.
