Genomic insights into the admixture history of Mongolic and Tungusic-speaking populations in southwestern East Asia
As a major part of modern Trans-Eurasian or Altaic language family, most of the Mongolic and Tungusic languages were mainly spoken in northern China, Mongolia and southern Siberia, but some were also found in southern China. Previous genetic surveys only focused on the northern Altaic-speaking popul...

As a major part of modern Trans-Eurasian or Altaic language family, most of the Mongolic and Tungusic languages were mainly spoken in northern China, Mongolia and southern Siberia, but some were also found in southern China. Previous genetic surveys only focused on the northern Altaic-speaking populations, however, the ancestral origin and genomic diversification of Mongolic and Tungusic-speaking populations from southwestern East Asia remain poorly understood due to the paucity of high-density sampling and genome-wide data. Here, we generated genome-wide data at nearly 700,000 single nucleotide polymorphisms (SNPs) in 26 Mongolian and 55 Manchu individuals collected from Guizhou province in southwest China. We applied principal component analysis (PCA), ADMIXTURE, f-statistics, qpWave/qpAdm analysis, qpGraph,TreeMix, Fst and ALDER to infer the fine-scale population genetic structure and admixture history. We found significant genetic differentiation between northern and southern Mongolic and Tungusic speakers, as one specific genetic cline of Manchu and Mongolian was identified in Guizhou province.
