Stone tools from Sudan's Eastern Desert.
[sciencythoughts.blogspot.com]
The key areas for the migration of Hominins from Africa into Eurasian appear to have been the Eastern Sahara Desert of Egypt and Sudan and the Arabian Peninsula. Two distinct groups of Hominins appear to have used this route, Homo erectus/ergaster in the Middle Pleistocene, and Homo sapiens in the Late Pleistocene. This area appears to have undergone a considerable cultural shift around the boundary between Marine Isotope Stages 7 and 6, i.e. about 191 000 years ago, with material associate with the Early Stone Age Acheulean Tradition, which is associated with Homo erectus/ergaster, and which had dominated Africa, Europe, and Asia for about 1.5 million years, being replaced by material associated with the Sangoan Complex, which is considered to be a Early Stone Age/Middle Stone Age transitional technology that might be associated with the arrival of Early Modern Humans in the area (although the earliest known Early Modern Human remains are associated with the more advanced Levallois technology).
