How was Bell Beaker economy related to Corded Ware and Early Bronze Age lifestyles? Archaeological, botanical and palynological evidence from the Hegau, Western Lake Constance region

The Europe wide spread of what has been called the Bell Beaker phenomenon remains an enigma of European prehistory. While most of the recent research stresses the ideological aspects of using Bell Beaker material culture, here we take a regional and economical perspective. We look for the chronological relationships and the economic choices of the Bell Beaker phase and of its closest neighbours in time and space: the Late Neolithic Corded Ware and the Early Bronze Age. We focus on the regional archaeological settlement history and present the hitherto richest European Bell Beaker-associated collection of palaeobotanical macro-remains, together with our high-resolution palynological work on annually laminated lake sediments. These different lines of evidence are tied together by an absolute chronology derived from new radiocarbon accelerated mass spectrometry (AMS) dates (now more than 200) and from the dendrodates from the World Heritage wet preserved pile dwellings. We show the preceding Late Neolithic, the actual Bell Beaker, and the following Early Bronze age economies each relying on different agricultural strategies that focus on distinct parts of the landscape. There is no link obvious between Late Neolithic and Bell Beaker, but there is between Bell Beaker and Early Bronze Age. Related to different modes of production, differences in ideology become visible in food preferences as well as in other parts of the material culture. We conclude that the Bell Beaker economy represents a re-orientation of the mode of production focusing on single, rather small farmsteads which often do not leave a distinct signal in the archaeological record.
