This marker-shaded sketchbook drawing is my artistic depiction of either one of two Neolithic women whose remains were found in a rock shelter at the site of Wadi Takarkori in the Libyan Sahara. They would have lived around 7,000 years ago when the Sahara was a grassland rather than a desert. Analysis of ancient DNA from their remains suggest that both women descended primarily from an isolated North African population intermediate in genetic affinity between most other African populations on the one hand and non-Africans on the other, possibly as a result of splitting off from the latter shortly before the “Out of Africa” migrations.
