New paper (behind paywall) Sahelian pastoralism from the perspective of variants associated with lactase persistence, by Priehodová et al. Am J Phys Anthropol (2020) e24116.
Interesting excerpts from the discussion (emphasis mine, minor modifications for clarity):
Our investigation of LP variant frequencies revealed new and interesting results related to the origins of pastoralism and subsequent gene flow between pastoralists and farmers in the Sahel/Savannah belt of Africa.
- We observed a clear distinction between regions west and east of Lake Chad: while variant −13910*T prevails in the western Sahel, where we found it only in pastoralists such as the Fulani,

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
