This study reports a cranio-morphometric analysis of female human remains from seven archaeological sites in China, Vietnam and Taiwan that date between 16,000 and 5300 BP. The aim of the analysis is to test the "two-layer" model of human dispersal in eastern Eurasia, using previously unanalysed female remains to balance the large sample of previously-analysed males. The resulting craniometric data indicate that the examined specimens all belong to the "first layer" of dispersal, and share a common ancestor with recent Australian and Papuan populations, and the ancient Jomon people of Japan.

Southern East Asia, including Guangxi and Fujian provinces in China, is home to diverse ethnic groups, languages, and cultures. Previous studies suggest a high complexity regarding population dynamics and the history of southern East Asians. However, large-scale genetic studies on ancient populations in this region are hindered by limited sample preservation.

Past human genetic diversity and migration between southern China and Southeast Asia have not been well characterized, in part due to poor preservation of ancient DNA in hot and humid regions. We sequenced 31 ancient genomes from southern China (Guangxi and Fujian), including two ∼12,000- to 10,000-year-old individuals representing the oldest humans sequenced from southern China. We discovered a deeply diverged East Asian ancestry in the Guangxi region that persisted until at least 6,000 years ago.

Article Synopsis
  • The study focuses on the deep population history of East Asia, utilizing ancient DNA from 166 individuals to explore migration patterns and ancestry connections over millennia.
  • It identifies a significant coastal migration during the Late Pleistocene and notes expansions in the Holocene from regions like Mongolia, the Amur River Basin, and the Yellow River, affecting language distributions and genetic ancestry.
  • The findings suggest complex interactions involving different lineages, including shared ancestry among Mongolic and Tungusic speakers, a major genetic contribution to the Han Chinese from Yellow River farmers, and a mix of northern and southern ancestries in Taiwan.
