Project
The aim of our project is to investigate the evolutionary roots of human adaptation to climatic and palaeoenvironmental shifts at the northern limit of their former distribution area. The archaeological record of Lower Saxony ( Northern Germany) with some outstanding sites shows that early humans inhabited this area since about 300 ka, but it is unclear whether this happened mostly during the temperate phases, or also during colder periods.
