Ancient DNA reveals a two-clanned matrilineal community in Neolithic China

Ancient DNA reveals a 4,500-year-old matrilineal community in Neolithic China.

Researchers analyzed DNA from 60 individuals buried in two cemeteries at the Fujia site in eastern China, dating to 2750–2500 BCE. They found that people were buried according to maternal clans, with high levels of intermarriage between the two groups. This suggests a matrilineal society where descent was traced through the mother, and the community practiced millet farming. The cemeteries were used for about 250 years, spanning at least 10 generations.

• The Fujia community was organized around two matrilineal clans, with burials strictly following maternal lines.
• High endogamy and intermarriage between the two cemeteries indicate strong social cohesion and identity.
• The community practiced millet agriculture near the coast and maintained a stable matrilineal lineage for at least 10 generations.

Sample interpretation

The site_samples count is 66, but the abstract mentions 60 individuals. The discrepancy may be due to additional samples or different counting methods. Y-chromosome data from 13 males show diverse haplogroups, including N-CTS962, N-Z4762, and C-F9765, suggesting multiple paternal lineages. Mitochondrial DNA is dominated by D5b1b (48 individuals), with M8a2'3 and M8a3 also common, indicating strong maternal clustering. All samples belong to the Dawenkou culture.

For genealogy enthusiasts

This study challenges the assumption that early societies were patrilocal. For ancestry enthusiasts, it shows that matrilineal systems existed in Neolithic China, and that mitochondrial DNA can reveal social organization. It also highlights the importance of combining genetic, archaeological, and isotopic data.
