Project D4 of the CRC 806 focuses on the question, as to whether the presence, or resp., the absence of humans can be interpreted as a response to natural or cultural environment by integrating data, methods and results from various former CRC-projects and from literature. This integrative approach is based on the analysis of chronological, spatial, geoarchaeological, archaeobiological and cultural data. One of the main questions concerns the reconstruction of diet and mobility of humans and animals. Based on the hypothesis that an increase in the consumption of meat correlates with lower population densities and perhaps higher mobility, we are interested in isotopic measurements of human and animal bones. The collected data will also allow for the reconstruction of foodwebs of various archaeological periods. This also includes the creation of a database of isotopic data.
