''Ancient genomic history and adaptation of human populations in Africa''

Abstract:
Genomic sequencing of archaeological material has revolutionised our understanding of the human past in Eurasia, but ancient DNA sequencing has yet to be comprehensively brought to benefit the study of Africa's past. I will review our current state of understanding of the genomic record of past African populations. Example insights from this recent research has included a new understanding of long-distance interconnectivity between early Holocene southern African and eastern African populations and new models of deep human population structure in Africa around the time of emergence of anatomically modern humans. Specifically, new results provide evidence for deep structure in west Africa that may reflect some of the earliest diversifications of population lineages contributing to present-day populations. These results caution against extrapolating genetic models of the past from present-day genetic diversity, and highlight the need for further ancient DNA studies in Africa.
