The research dealt with an analytical study and scientific material collection in the Upper Atbara region in eastern Sudan. The researchers extracted from this study that the early development of the Paleolithic industries in Sudan has to do with assets in North Africa and Europe and that the migration of early human groups was associated with the flow of the Nile and the Atbara River and that nature helped settle in the upper reaches of the Atbara River as well as the Red Sea coasts and The Atbara River is the most likely area for early migrations to North Africa, Asia, and Europe later.
