Roughly 100,000 years ago, humans migrated out of Africa and started to populate the globe. Although the human species is now associated with significant phenotypic variation, all humans have a genetic origin in Africa. The genomes of people currently living in Africa are more varied than those of people living anywhere else on Earth. Studying the genomes of Africans thus offers important opportunities to characterize and understand genomic variation. Despite this, Africans are largely underrepresented as both research participants and scientists in genetics and genomics.
