Genetic ancestry of Hadza and Sandawe peoples reveals ancient population structure in Africa

Open access paper Genetic Ancestry of Hadza and Sandawe Peoples Reveals Ancient Population Structure in Africa, by Shriner, Tekola-Ayele, Adeyemo, & Rotimi, GBE (2018).

Abstract (emphasis mine):

The Hadza and Sandawe populations in present-day Tanzania speak languages containing click sounds and therefore thought to be distantly related to southern African Khoisan languages. We analyzed genome-wide genotype data for individuals sampled from the Hadza and Sandawe populations in the context of a global data set of 3,528 individuals from 163 ethno-linguistic groups. We found that Hadza and Sandawe individuals share ancestry distinct from and most closely related to Omotic ancestry

Potential Afroasiatic Urheimat near Lake Megachad


The publication of new ancient DNA samples from Africa is near, according to people at the SMBE meeting. As reported by, a group by Pontus Skoglund has analysed new samples (complementing the study made by Carina Schlebusch), so we will have ancient samples of Africans from 300 to 6,000 years ago. They have been compared to the data of modern African populations, and among their likely conclusions (to be published):

  • Several thousand years ago, likely Tanzanian herders migrated far and wide, reaching Southern Africa centuries before the first farmers.
  • West Africans were likely early contributors to the
