In the early 3rd millennium BC, the Corded Ware culture appeared in Northern Europe. Its peoples were of marked steppe-related ancestry and traced their origins in cultures further east. This period is distinguished by the construction of numerous defensive palisades in Funnelbeaker territory, which may be a sign of violent conflict between the Funnelbeakers, Corded Ware, and Pitted Ware. By 2650 BC, the Funnelbeaker culture had been replaced by the Corded Ware culture. Genetic studies suggest that Funnelbeaker women were incorporated into the Corded Ware culture through intermixing with incoming Corded Ware males, and that people of the Corded Ware culture continued to use Funnelbeaker megaliths as burial grounds. Subsequent cultures of Late Neolithic, Bronze Age, and Iron Age Central Europe display strong maternal genetic affinity with the Funnelbeaker culture.
