东南亚（SEA）的人类占领历史仍然存在很大争议。目前的证据表明，直到4000年前，当农业经济发展和扩大，限制觅食群体到偏远的栖息地之前，海洋一直被Hoabelian狩猎采集者占据。一些人认为农业发展是本土的;另一些人则倾向于“双层”假说，认为农民向南扩张导致了今天东南亚的遗传多样性。通过对26个古人类基因组（25个来自东南亚，1个来自日本绳纹）进行测序，我们发现这两种解释都不符合东南亚历史的复杂性：Hoababhunter-gatherers和东亚农民都对当前东南亚的多样性做出了贡献，进一步的移民影响了东南亚和越南。我们的研究结果有助于解决东南亚史前史中长期存在的争议之一。
The human occupation history of Southeast Asia (SEA) remains heavily debated. Current evidence suggests that SEA was occupied by Hoabinhian hunter-gatherers until similar to 4000 years ago, when farming economies developed and expanded, restricting foraging groups to remote habitats. Some argue that agricultural development was indigenous; others favor the "twolayer" hypothesis that posits a southward expansion of farmers giving rise to present-day Southeast Asian genetic diversity. By sequencing 26 ancient human genomes (25 from SEA, 1 Japanese Jomon), we show that neither interpretation fits the complexity of Southeast Asian history: Both Hoabinhian hunter-gatherers and East Asian farmers contributed to current Southeast Asian diversity, with further migrations affecting island SEA and Vietnam. Our results help resolve one of the long-standing controversies in Southeast Asian prehistory.
