Qadan

Qadan [CP].
Mesolithic Stage communities living in Nubia in the upper Nile Valley prior to 9000 BC, at a time of relatively high water levels in the Nile, characterized by a diverse stone tool industry that is taken to represent increasing degrees of specialization and locally differentiated regional groupings. There is some evidence of conflict between the groups. The Qadan economy was based on fishing, hunting, and the extensive use of wild grain.
