Dispersion of ancient humans in east Asia during the late Pleistocene: Geography, archaeology and ecology

Abstract

Guan Ying, Zhou Zhenyu

During the late Pleistocene, external population entered East Asia through four possible migration routes and introduced Levallois and blade techniques into China. Most sites in China with these external lithic technology technologies are distributed about north of 34°N and around 38-24 ka BP. Using an ecological model, we inferred that the extinction rate for these populations on a millennial scale was between 75% and 100%, and the number of small populations was between 7 and 189. This number of small populations was far less than the local population. We can see from this that although populations from peripheral areas crossed a series of geographical barriers and gradually entered East Asia, their population was too small, and it was difficult for them to sustain the inheritance of their own cultural and technological factors. Furthermore, facing competition and confrontation with different populations, they eventually disappeared
