A study appearing in Cell Reports has analyzed the genomes of over 100 individuals from the Cucuteni-Tripolye culture of Eastern Europe. The findings document a profound shift in social structure between 3200 BCE and 2800 BCE, as earlier communal, matrilocal burial patterns were replaced by patrilineal kinship clusters following contact with Steppe pastoralist groups.
This genomic data provides a clear biological timeline for the 'collapse' of Old Europe's mega-settlements. The researchers argue that the transition was not purely violent but involved a complex integration of social norms, where new genetic lineages gradually established control over land and resources, leading to the rise of more hierarchical Bronze Age societies.
