On June 24, the team of Fu Qiaomei, a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences, cooperated with Ji Xueping, a researcher at the Yunnan Institute of Cultural Relics and Archaeology, Wang Wei, a professor at Shandong University, and Guangxi Institute of Cultural Relic Conservation and Archaeology.
Fu Qiaomei’s team used ancient nuclear genome capture technology to overcome the difficulty of poor preservation of ancient DNA due to the hot and humid environment in the south of East Asia, and successfully captured 30 cases (15 sites) from 170 human bones or fossils (30 sites) in Guangxi ) The ancient human genome from 10686 to 294 years ago, and a case of the ancient human genome from Fujian province 11747 years ago
Among them, the two human individuals from Longlin in Guangxi and Qihedong in Fujian are dated earlier than 10,000 years.
Previously, genome studies of ancient humans in Southeast Asia and southern China showed that the early populations of the two places had very different genetic histories
In general, the study first revealed the diversity of Asian populations 11,000 years ago.
Secondly, it reveals the evolution and change history of the population in Guangxi and Fujian in southern China from a dynamic perspective, and highlights the important position of Guangxi in the evolution of the Asian population—not only the geographic intersection of East Asia and Southeast Asia, but also the two.
Finally, it was discovered that population turnover occurred in this area 6000 years later, providing important clues for tracing the history of ethnic minorities in China
