The Prehistoric Peopling of Southeast Asia

AI interpretationAI-generated

Ancient DNA from 26 Southeast Asians rewrites the region's prehistoric peopling story.

This study sequenced 26 ancient genomes, mostly from Southeast Asia plus one Jomon from Japan. It tested two competing ideas: that farming spread locally, or that farmers from East Asia replaced hunter-gatherers. Neither fits. Instead, both Hòabìnhian hunter-gatherers and East Asian farmers contributed to modern Southeast Asian ancestry, with later migrations further shaping island Southeast Asia and Vietnam.

• Both Hòabìnhian hunter-gatherers and East Asian farmers contributed ancestry to present-day Southeast Asians.
• Neither the local-development nor the simple two-layer farming model fully explains Southeast Asian prehistory.
• Additional later migrations affected island Southeast Asia and Vietnam, adding complexity.

Sample interpretation

The site sample includes 2 ancient individuals from Kelantan, both with resolved Y lineages: O-F3288 and D-TY92016. One is linked to the Hòabìnhian culture. Their mtDNA types are F3b1a-a and M21b1a. These two genomes represent both hunter-gatherer and farmer-related ancestries in one region, matching the study's mixed-ancestry conclusion.

For genealogy enthusiasts

For ancestry fans, this means Southeast Asian roots are not a simple farmer-versus-forager story. Both ancient groups left genetic marks, so your regional DNA may reflect layered hunter-gatherer, farmer, and later migration histories.
