DESCRIPTION:Genomic sequencing of archaeological material has revolutionis
 ed our understanding of the human past in Eurasia\, but ancient DNA sequen
 cing 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 re
 cord of past African populations. Example insights from this recent resear
 ch has included a new understanding of long-distance interconnectivity bet
 ween early Holocene southern African and eastern African populations and n
 ew models of deep human population structure in Africa around the time of 
 emergence of anatomically modern humans. Specifically\, new results provid
 e evidence for deep structure in west Africa that may reflect some of the 
 earliest diversifications of population lineages contributing to present-d
 ay populations. These results caution against extrapolating genetic models
  of the past from present-day genetic diversity\, and highlight the need f
 or further ancient DNA studies in Africa.
