After its establishment, the Funnelbeaker culture rapidly spread into southern Scandinavia and Poland, in what appears to have been a well-organized colonizing venture. In southern Scandinavia it replaced the Ertebølle culture, which had maintained a Mesolithic lifestyle for about 1500 years after farming arrived in Central Europe. The emergence of the Neolithic British Isles through maritime colonization by Michelsberg-related groups occurred almost at the same time as the expansion of the Funnelbeaker culture into Scandinavia, suggesting that these events may be connected. Although they were largely of Early European Farmer (EEF) descent, people of the Funnelbeaker culture had a relatively high amount of hunter-gatherer admixture, particularly in Scandinavia, suggesting that hunter-gatherer populations were partially incorporated into it during its expansion into this region. People of the Funnelbeaker culture often had between 30% and 50% hunter-gatherer ancestry depending on the region.
