These Southeast Asians descend from three waves of ancient immigration
DNA analysis shows that humans arrived in three waves in Southeast Asia - ancient human history

The first whole-genome analysis of ancient human fossils found in Southeast Asia revealed that humans arrived here in three distinct waves : hunter – gatherers about 45,000 years ago, farmers from China during the Neolithic Period around 4,500 years ago, and finally Bronze Age imigrants again from China between 1,000 and 3,000 years ago. These movements introduced ancestry types that are today associated with speakers of different languages. Descendants of these three waves can still be identified on the basis of their DNA, suggesting that immigrants from each wave have not mixed substantially with those from another wave. This is different from ancient European immigrants, where ancestral DNA patterns have faded over time as populations mingled.
