Schroeder et al. (2019) examined 15 skeletons from the Koszyce mass grave in southern Poland, which is ascribed to the Globular Amphora culture. The individuals were all shown to be members of an extended family, and to have been buried with great care by someone who knew them very well. Most of them were female and children. All had been executed by a violent blow to the head, perhaps by invading Corded Ware groups. The older males of the family are missing from the grave, suggesting that they were away or had fled. Of the eight samples of Y-DNA extracted, all were found to belong to I2a-L801. The fifteen samples of mtDNA extracted belonged to various subclades of T, H, J, K, HV. The skeletons were determined to have about 70% Neolithic farmer ancestry and 30% Western Hunter-Gatherer ancestry, meaning they had no steppe ancestry. The archaeological and genetic evidence collected from the grave indicated that the Globular Amphora culture was patriarchal and kinship-oriented, which appears to have been the norm for Late Neolithic communities in Central Europe.
