Human evolutionary history in Eastern Eurasia using insights from ancient DNA.

Human evolutionary history in Eastern Eurasia using insights from ancient DNA. Curr Opin Genet Dev. 2020 Jul 17;62:78-84 Authors: Zhang M, Fu Q Abstract Advances in ancient genomics are providing unprecedented insight into modern human history. Here, we review recent progress uncovering prehistoric populations in Eastern Eurasia based on ancient DNA studies from the Upper Pleistocene to the Holocene. Many ancient populations existed during the Upper Pleistocene of Eastern Eurasia-some with no substantial ancestry related to present-day populations, some with an affinity to East Asians, and some who contributed to Native Americans. By the Holocene, the genetic composition across East Asia greatly shifted, with several substantial migrations. Three are southward: an increase in northern East Asian-related ancestry in southern East Asia; movement of East Asian-related ancestry into Southeast Asia, mixing with Basal Asian ancestry; and movement of southern East Asian ancestry to islands of Southeast Asia and the Southwest Pacific through the expansion of Austronesians. We anticipate that additional ancient DNA will magnify our understanding of the genetic history in Eastern Eurasia. PMID: 32688244 [PubMed - as supplied by publisher]
