| 描述信息 |
Present-day East Asians share a close relationship to each other but lack a well-established genetic history. We sequenced genome-wide SNPs from 26 individuals spanning a period of 9,500-300 years ago from East Asia, overlapping the Neolithic period in China. These data support that ancient East Asians are closest to today's East Asians and are divergent from ancient Southeast Asian hunter-gatherers. Furthermore, Neolithic East Asians show higher genetic differentiation than today's East Asians, likely due to increased gene flow, particularly of northern East Asian ancestry into southern East Asia. Ancestry associated with Neolithic southern East Asians from the mainland is closest to Austronesians, indicating a proto-Austronesian origin mainland southern China. Overall, modern East Asian genetics have been impacted by both northern and southern East Asians since 9,500 years ago. |
