Tassi et al. (2017) extracted fifteen samples of
mtDNA. The majority of the samples belonged to subclades of
U and
Haplogroup H (mtDNA), along with
J,
W and
K. The remains were found to be closely related to
Early European Farmers and
Western Hunter-Gatherers, with little genetic relation to the
Yamnaya culture of
Western Steppe Herders in the east. The authors of the study suggested that the Globulara Amphora culture could possibly have been in contact with the Yamnaya, but that the interaction would mostly have been at the cultural level with very limited migration, if any, contrary to the predictions of Gimbutas’s Kurgan hypothesis. Mathieson et al. (2018) included a genetic analysis of eight males of the Globular Amphora culture. Three of them carried
haplogroup I2a2a1b and a subclade of it; two carried
I2a2; one carried
I2; one carried
BT and one carried
CT. According to admixture analysis they also had approximately 70% EEF ancestry and 30% WHG ancestry, some of them with negligible
Eastern Hunter-Gatherer and Yamnaya traces. 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 mtDNA samples consisted of various subclades of
T,
H,
J,
K,
HV. The skeletons showed about 70% EEF ancestry and 30% WHG ancestry, meaning the population was distinct from neighboring Corded Ware groups in lacking steppe-related ancestry. The archaeological and genetic evidence collected from the grave indicated that the Globular Amphora culture was
patrilineal,
patrilocal and
patriarchal and kinship-oriented, which appears to have been the norm for Late Neolithic communities in
Central Europe. Papac et al. (2021) examined 3 Globular Amphora individuals from Vlineves in the
Czech Republic. They were found to harbour mainly EEF ancestry and about 25–30% WHG ancestry. The 3 Globular Amphora culture males in the study belonged to Y-haplogroup R1b–V88. ==Gallery==
