Marija Gimbutas assumed an Indo-European origin,[1] though this is contradicted by newer genetic studies that show a connection to the earlier wave of Early European Farmers rather than to Western Steppe Herders from the Ukrainian and south-western Russian steppes.

Desite several minor regional to local differences, in the GAC distribution there are two main GAC-groups, distinguished by their networks, as recently pointed out by Johannes Müller[3].

The eastern group (the Vistula-Podolia network) share specific pottery sub-types and the exploitation of Krzemionki silex.

[3] The economy was based on raising a variety of livestock, pigs particularly in the earlier phase of the eastern GAC groups, in distinction to the Funnelbeaker culture's preference for cattle.

Some evidence, such as paired oxen burials, suggests that the GAC might have made use of cattle-drawn wagons or carts.

The supporters of the Kurgan hypothesis point to these distinctive burial practices and state this may represent one of the earliest migrations of Indo-Europeans into Central Europe.

[9] 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.

Mathieson et al. (2018) included a genetic analysis of eight males of the Globular Amphora culture.

[11] Schroeder et al. (2019) examined 15 skeletons from the Koszyce mass grave in southern Poland, which is ascribed to the Globular Amphora culture.

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.
