Ancient DNA reveals diverse community organizations in the 5th millennium BCE Carpathian Basin

Ancient DNA reveals two contrasting kinship systems in nearby Copper Age communities.

This study analyzed 125 ancient genomes from the Carpathian Basin (4800-3900 BCE). Despite shifts in culture and burial, genetic continuity persisted. One large cemetery was genetically diverse, while another site, only 100 km away, was homogeneous with close kin, patrilineality, and patrilocality. These contemporaneous communities used similar material culture but had radically different social structures.

• High genetic continuity across the Late Neolithic to Early Copper Age despite cultural changes.
• One community cemetery was genetically diverse, while another was homogeneous and closed with many consanguineous relationships.
• Evidence of patrilineality and patrilocality at the homogeneous site, contrasting with the diverse site.

Sample interpretation

The site_samples count is 21 Y-chromosome samples from five sites. Y haplogroups include R-P310 (5), H-P96 (2), E-L618 (2), I-CTS6414 (2), and others. Mitochondrial haplogroups include T2b (3), J1c (2), and various U and J subtypes. The largest site sample is I7132.SG with 11 individuals, followed by I5114 (5) and I5105 (3). These genetic markers reflect the paternal and maternal lineages present in these communities.

For genealogy enthusiasts

For ancestry enthusiasts, this shows that ancient communities living close together could have very different kinship rules. Your genetic matches may reflect patrilocal or exogamous practices, so interpreting ancient DNA requires site-specific context, not just broad cultural labels.
