Funnelbeaker culture

The Funnel(-neck-)beaker culture, in short TRB or TBK (German: Trichter(-rand-)becherkultur, Dutch: Trechterbekercultuur; Danish: Tragtbægerkultur; c. 4300–2800 BCE), was an archaeological culture in north-central Europe. It developed as a technological merger of local neolithic and mesolithic techno-complexes between the lower Elbe and middle Vistula rivers. These predecessors were the (Danubian) Lengyel-influenced Stroke-ornamented ware culture (STK) groups/Late Lengyel and Baden-Boleráz in the southeast, Rössen groups in the southwest and the Ertebølle-Ellerbek groups in the north. The TRB introduced farming and husbandry as major food sources to the pottery-using hunter-gatherers north of this line.

The TRB techno-complex is divided into a northern group including Northern Germany and southern Scandinavia (TRB-N, roughly the area that previously belonged to the Ertebølle-Ellerbek complex), a western group in the Netherlands between the Zuiderzee and lower Elbe that originated in the Swifterbant culture, an eastern group centered on the Vistula catchment, roughly ranging from Oder to Bug, and south-central groups (TRB-MES, Altmark) around the middle and upper Elbe and Saale. Especially in the southern and eastern groups, local sequences of variants emerged. In the late 4th millennium BCE, the Globular Amphora culture (GAC) replaced most of the eastern and subsequently also the southern TRB groups, reducing the TRB area to modern northern Germany and southern Scandinavia.

The younger TRB in these areas was superseded by the Single Grave culture (EGK) at about 2800 BCE. The north-central European megaliths were built primarily during the TRB era.

The Funnelbeaker culture is named for its characteristic ceramics, beakers and amphorae with funnel-shaped tops, which were found in dolmen burials.

The Funnelbeaker culture emerged in northern modern-day Germany c. 4100 BCE. Archaeological evidence strongly suggests that it originated through a migration of colonists from the Michelsberg culture of Central Europe. The Michelsberg culture is archaeologically and genetically strongly differentiated from the preceding post-Linear Pottery cultures of Central Europe, being distinguished by increased levels of hunter-gatherer ancestry. Its people were probably descended from farmers migrating into Central Europe out of Iberia and modern-day France, who in turn were descended from farmers of the Cardial Ware cultures who had migrated westwards from the Balkans along the Mediterranean coast. Connections between the Funnelbeakers and these farmers of the Atlantic coast is supported by genetic evidence.

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.

During later phases of the Neolithic, the Funnelbeaker culture re-expanded out of Scandinavia southwards into Central Europe, establishing several regional varieties. This expansion appears to have been accompanied by significant human migration. The southward expansion of the Funnelbeaker culture was accompanied by a substantial increase in hunter-gatherer lineages in Central Europe. The Funnelbeaker communities in Central Europe which emerged were probably quite genetically and ethnically mixed, and archaeological evidence suggests that they were relatively violent.

From the middle of the 4th millennium BCE, the Funnelbeaker culture was gradually replaced by the Globular Amphora culture on its southeastern fringes, and began to decline in Scandinavia.
