African population history: an ancient DNA perspective
Mário Vicente, Carina M. Schlebusch
Abstract
The history of human populations in Africa is complex and includes various demographic events that influenced patterns of genetic variation across the continent. Through genetic studies of modern-day, and most recently, ancient African genetic variation, it became evident that deep African history is captured by the relationships among hunter-gatherers. Furthermore, it was shown that agriculture had a large influence on the distribution of current-day Africans. These later population movements changed the demographic face of the continent and descendants of farming groups today form the majority populations across Africa. Ancient DNA methods are continually evolving, and we see evidence of this in how research has advanced in the last decade. With the increased availability of full genomic data from diverse sets of modern-day and prehistoric Africans we now have more power to infer human demography. Future ancient DNA research promises to reveal more detailed stories of human prehistory in Africa.
