The Mid-Pleistocene is a critical epoch for studying the relationship between the human evolution and climatic changes. Because that not only the ecological environment is very sensitive to climate changes but also there are rich of the Paleolithic sites of Mid-Pleistocene age, the north China thus has an unique advantage for studying the human migration and evolution during the Mid-Pleistocene and the environmental forcing behind that. However, due to the serious deficiencies in Geochrological and Paleoenvrionmental studies for these Paleolithic sites of Mid-Pleistocene age in north China, intensive studies on the critical issues of the early human evolution have been seriously restricted. In this study, we firstly date the representative Mid-Pleistocene paleolithic sites precisely in north China. Secondly, the sedimentology, Geochemical and biological proxies of these sites were studied in detail. By reconstructing the past climatic and environmental conditions around these sites using the methods of quantitative reconstruction, we try to explore the relationships between the time of human activities in Mid-Pleistocene period and the glacial-interglacial cycles, and then to reveal the impact of East Asian monsoon intensity changes on the past human migration and evolution. Therefore, this study may be hopeful for making great progress in the past human migration and evolution model and the theoretic studies on the relationship between the human evolution and climatic changes.
