Genetics, Egypt, and History: Interpreting Geographical Patterns of Y Chromosome Variation

Abstract

Modern Egypt, the site of Africa's earliest state, lies near the crossroads of two other continents, and has had historic interactions with all its neighboring regions. This alone would make it an ideal place to study historical population biology. Egypt can also be conceptualized as a linear oasis in the eastern Sahara, one that traverses several regions of Africa. An oasis can be a way station or serve as a refugium, as well as be a place of settlement with its own special biological and cultural adaptive strategies. Both of these perspectives—crossroads and oasis/refugium—can be expected to provide insight into the processes that could have affected the Nile valley's populations/peoples. From these vantage points this presentation will examine aspects of what might be called the historical genetics of the Nile valley, with a focus on the Y chromosome. The time-frame is the late pleistocene through holocene; within this there are different levels of biocultural history. Of special interest here is patterns of north-south variation in the Egyptian Nile valley.
