Genetic formation and regional disparities of Kra-Dai and Hmong-Mien speakers inferred from ancient genomes of cave burial populations in southwest China

Ancient genomes from Guangxi caves reveal genetic roots of Kra-Dai and Hmong-Mien speakers.

This study sequenced 14 ancient genomes from cave burials in historical Guangxi, southwest China. These individuals likely belonged to early Kra-Dai or Hmong-Mien speaking populations. The genetic data show both shared ancestry and regional differences, helping to trace how these language families formed and spread. The findings highlight the importance of southwest China as a crossroads for ancient human migrations.

• 14 new ancient genomes from Guangxi cave burials provide direct genetic evidence for Kra-Dai and Hmong-Mien origins.
• Y-chromosome lineages are diverse, with C-F1059 (3 samples) and several O subclades, suggesting multiple paternal contributions.
• Mitochondrial DNA is also varied, with B5a1c appearing in 3 individuals, indicating maternal diversity and possible local continuity.

Sample interpretation

Among 14 samples, 10 had resolvable Y-chromosome haplogroups. The most common Y lineage is C-F1059 (3 samples), followed by several O haplogroups (O-B462, O-SK1630, O-FTB24486, O-BY168242, O-N5) and additional C lineages (C-AM00848, C-AM00612). Mitochondrial DNA includes B5a1c (3 samples), M7b1a1a3, M7c1b2, F1c1a, M71-a, and Z4. This mix suggests both deep local roots and connections to broader East Asian populations.

For genealogy enthusiasts

For ancestry enthusiasts, this study shows that southwest China was a key region where Kra-Dai and Hmong-Mien speakers formed. The diverse Y and mtDNA lineages mean your genetic ties to these groups may trace back to multiple ancient waves, not a single origin.
