Unraveling ancestry, kinship, and violence in a Late Neolithic mass grave
Open accessAbstract
The third millennium BCE was a period of major cultural and demographic changes in Europe that signaled the beginning of the Bronze Age. People from the Pontic steppe expanded westward, leading to the formation of the Corded Ware complex and transforming the genetic landscape of Europe. At the time, the Globular Amphora culture (3300–2700 BCE) existed over large parts of Central and Eastern Europe, but little is known about their interaction with neighboring Corded Ware groups and steppe societies. Here we present a detailed study of a Late Neolithic mass grave from southern Poland belonging to the Globular Amphora culture and containing the remains of 15 men, women, and children, all killed by blows to the head. We sequenced their genomes to between 1.1- and 3.9-fold coverage and performed kinship analyses that demonstrate that the individuals belonged to a large extended family. The bodies had been carefully laid out according to kin relationships by someone who evidently knew the deceased. From a population genetic viewpoint, the people from Koszyce are clearly distinct from neighboring Corded Ware groups because of their lack of steppe-related ancestry. Although the reason for the massacre is unknown, it is possible that it was connected with the expansion of Corded Ware groups, which may have resulted in competition for resources and violent conflict. Together with the archaeological evidence, these analyses provide an unprecedented level of insight into the kinship structure and social behavior of a Late Neolithic community.

The Neolithic period is increasingly recognised as one marked by conflict and instability, driven by profound social and demographic transformations linked to the shift from foraging to farming.
“This period is increasingly recognised as one marked by conflict and instability, driven by profound social and demographic transformations linked to the shift from foraging to farming.”

The Results and Discussion section (‘Intergroup Conflict and Violence’; page not provided) describes Neolithic massacres associated with population pressure, resource competition, and the expansion of new groups. The Concluding Remarks call the early third millennium BCE unstable and tumultuous. Neither passage links that violence to the shift from foraging to farming, and the paper’s account is narrower than a claim about the Neolithic period as a whole. (LLM, conf=0.86)
Experimental — accuracy not yet measuredHigh population pressure, competition over resources, and interactions between indigenous Mesolithic groups and incoming Neolithic farming communities often resulted in violent confrontations of varying scale.
“High population pressure, competition over resources, and interactions between indigenous Mesolithic groups and incoming Neolithic farming communities often resulted in violent confrontations of varying scale59,60]65–68.”

The Results and Discussion section (“Intergroup Conflict and Violence”; page unavailable) links Neolithic lethal violence and massacres to population pressure, resource competition, and expansion into occupied territory. It does not identify violent confrontations specifically between indigenous Mesolithic groups and incoming Neolithic farming communities; its discussion of the Koszyce massacre instead concerns possible conflict involving Globular Amphora and Corded Ware groups. (LLM, conf=0.88)
Experimental — accuracy not yet measuredA similar age pattern is observed at Neolithic sites in central Europe, where mass violent events involving entire communities or family groups have been recorded.

In cases where injuries caused by interpersonal violence and cannibalistic processing overlap, it is often difficult to distinguish butchering from killing.

The Results and Discussion section identifies cranial fractures as evidence that the Koszyce individuals were killed by blows to the head. Searches for cannibalistic processing, butchering, and difficulty distinguishing butchering from killing found no passage addressing that diagnostic problem. (LLM, conf=0.75)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
