Abstract: Africa is the ancestral homeland of all modern human populations within the past 300,000 years. It is also a region of tremendous cultural, linguistic, climatic, phenotypic and genetic. Despite the important role that African populations have played in human history, they remain one of the most underrepresented groups in human genomics studies. A comprehensive knowledge of patterns of variation in African genomes is critical for a deeper understanding of human genomic diversity, the identification of functionally important genetic variation, the genetic basis of adaptation to diverse environments and diets, and for reconstructing modern human origins. African populations practice diverse subsistence patterns (hunter-gatherers, pastoralists, agriculturalists, and agro-pastoralists) and live in diverse environments with differing pathogen exposure (tropical forest, savannah, coastal, desert, low altitude, and high altitude) and, therefore, are likely to have experienced local adaptation. In this talk I will discuss results of analyses of integrative genomic analyses to reconstruct human evolutionary history in Africa as well as the genetic basis of adaption to diverse environments.
