Open access African evolutionary history inferred from whole genome sequence data of 44 indigenous African populations, by Fan et al. Genome Biology (2019) 20:82.
Interesting excerpts (emphasis mine):
To extend our knowledge of patterns of genomic diversity in Africa, we generated high coverage (30×) genome sequencing data from 43 geographically diverse Africans originating from 22 ethnic groups, representing a broad array of ethnic, linguistic, cultural, and geographic diversity (Additional file 1: Table S1). These include a number of populations of anthropological interest that have never previously been characterized for high-coverage genome sequence diversity such as Afroasiatic-speaking El

Interesting new paper (behind paywall) Megalakes in the Sahara? A Review, by Quade et al. (2018).
Abstract (emphasis mine):
The Sahara was wetter and greener during multiple interglacial periods of the Quaternary, when some have suggested it featured very large (mega) lakes, ranging in surface area from 30,000 to 350,000 km2. In this paper, we review the physical and biological evidence for these large lakes, especially during the African Humid Period (AHP) 11–5 ka. Megalake systems from around the world provide a checklist of diagnostic features, such as multiple well-defined shoreline benches, wave-rounded beach gravels where coarse material is

The publication of new ancient DNA samples from Africa is near, according to people at the SMBE meeting. As reported by Anthropology.net, 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
