Abstract

Background: Southwest China has been pivotal for agricultural spread, ethnic formation, and cultural diffusion. However, the genetic diversity and population structure of this area remain insufficiently explored, especially during the historical period.

Results: Here, we report genome-wide data of eight ancient individuals from the Songshan site in Guizhou dating back to the Song and Ming Dynasty. Our results reveal that most Songshan individuals are closely related to the Yellow River Basin farmers, while also showing significant genetic influences from southern East Asia, including affinities with ancients in Guangxi, coastal Fujian, and Southeast Asia. Additionally, some Songshan individuals displayed a high genetic affinity with local Hmong-Mien populations.

Conclusions: These findings underscore the complexity of genetic interactions and population movements during the historical period, providing new insights into the genetic landscape and ethnic formation processes in Southwest China.

中国西南地区古代基因组揭示了历史时期不同种群间的遗传相互作用。

背景：西南地区是农业传播、民族形成和文化传播的枢纽。然而，该地区的遗传多样性和种群结构仍未得到充分的研究，特别是在历史时期。结果：在这里，我们报告了贵州松山遗址8个古人类的全基因组数据，这些个体可以追溯到宋明时期。我们的研究结果表明，大多数松山个体与黄河流域的农民有密切的关系，同时也显示出来自东亚南部的显著遗传影响，包括与广西、福建沿海和东南亚的古人有亲缘关系。此外，一些松山个体与当地苗族群体表现出较高的遗传亲和力。结论：这些发现强调了历史时期遗传相互作用和人口流动的复杂性，为研究西南地区的遗传景观和民族形成过程提供了新的见解。
