The human landscape in East and Southeast Asia is vastly complex, and successful retrieval of genome-wide data from prehistoric humans of southern East Asia is sparse. We successfully sampled 127 ancient human genomes from southwestern China. A 7100-year-old female individual from central Yunnan shows a previously unsampled Basal Asian ancestry related to a ghost population that contributed to Tibetan Plateau populations. Central Yunnan populations dating to 5500 to 1400 years before present show an East Asian ancestry distinct from northern or southern East Asian ancestries that contributed to present-day East and Southeast Asians, particularly Austroasiatic speakers, and emphasizes the importance of the Red River valley for proto-Austroasiatic population history. Diverse Asian ancestries are represented in humans sampled from Yunnan, clarifying past population dynamics related to both Tibetan and Austroasiatic origins.
