 This suggests that modern Southern Han populations may possess a non-trivial number of male ancestors who were originally affiliated with some Austronesian-related culture, or who at least shared some genetic affinity with many of the ancestors of modern Austronesian peoples.This lineage is found frequently in Austronesians, southern Han Chinese, and Kra-Dai peoples.This lineage is presumed to be a marker of the prehistoric Austronesian expansion, with possible origins encompassing the regions along the southeastern coast of China and neighboring Taiwan, and is found among modern populations of Maritime Southeast Asia and Oceania .
