Across the flat, fertile floodplains of central Bohemia, the Rivnac presence in the late Neolithic emerges like a series of footprints in wet clay. Archaeological data from Kolín I, Toušeň, Tuchoměřice and Velké Přílepy place human activity between 3091 and 2633 BCE, a window when local farming traditions interacted with wider Central European Neolithic networks. Material culture associated with the Rivnac horizon shows continuity with preceding Neolithic farmer groups — pottery forms, polished stone tools, and burial practices — yet subtle changes in settlement layout hint at evolving social rhythms.
Genetically, the ten analyzed individuals provide a preliminary but vivid picture: Y-chromosome lineages dominated by haplogroup G and a secondary presence of H align with patterns seen in other Neolithic farming communities in Central and Southeastern Europe. Maternal lineages (HV, V3c, J, H variants) underscore continuity of farmer-associated mtDNA but also hint at local diversity potentially driven by micro-regional interactions. Limited evidence suggests these communities were not isolated islands but part of a tapestry of movement and exchange across the Danube corridor and beyond.
Because the dataset is small, interpretations must remain cautious. Archaeological contexts combined with genetic snapshots, however, allow us to trace how Rivnac groups rooted themselves in Bohemia amid broader late-Neolithic transformations.
