Penn Researchers Add Genetic Data to Archaeology and Linguistics to Get Picture of African Population History
PHILADELPHIA –- Genetic researchers from the University of Pennsylvania have combined data from existing archaeological and linguistic studies of Africa with human genetic data to shed light on the demographic history of the continent from which all human activity emerged.
The study reveals not just a clearer picture of the continent’s history but also the importance of having independent lines of evidence in the interpretation of genetic and genomic data in the reconstruction of population histories.
