“…However, the exact origin of the C-14010 variant in southern Africa is still unknown; the C-14010 variant could have been introduced~1,000 years ago by eastern African Bantu-speaking populations, who could have acquired the variant through admixture with neighboring pastoralist groups. 81,84,[87][88][89][90][91] Alternatively, the presence of the C-14010 variant in southern Africa could have been due to gene flow from eastern Africa prior to the Bantu expansion, corresponding with the archeological record that indicates the presence of cattle in southern Africa (Zambia) as early as 2,400 years ago, 76,92 and subsequent introduction of the C-14010 mutation into South African pastoralist communities. [92][93][94] Indeed, archeological and genetic data suggest that there could have been early admixture between ''Khoe-Khoe'' populations as far north as Zambia and pastoralist populations originating from eastern Africa and then subsequent admixture between the ''Khoe-Khoe'' and other populations in southern Africa.…”

In humans, the ability to digest lactose, the sugar in milk, declines after weaning because of decreasing levels of the enzyme lactase-phlorizin hydrolase, encoded by LCT. However, some individuals maintain high enzyme amounts and are able to digest lactose into adulthood (i.e., they have the lactase-persistence [LP] trait). It is thought that selection has played a major role in maintaining this genetically determined phenotypic trait in different human populations that practice pastoralism. To identify variants associated with the LP trait and to study its evolutionary history in Africa, we sequenced MCM6 introns 9 and 13 and ~2 kb of the LCT promoter region in 819 individuals from 63 African populations and in 154 non-Africans from nine populations. We also genotyped four microsatellites in an ~198 kb region in a subset of 252 individuals to reconstruct the origin and spread of LP-associated variants in Africa. Additionally, we examined the association between LP and genetic variability at candidate regulatory regions in 513 individuals from eastern Africa. Our analyses confirmed the association between the LP trait and three common variants in intron 13 (C-14010, G-13907, and G-13915). Furthermore, we identified two additional LP-associated SNPs in intron 13 and the promoter region (G-12962 and T-956, respectively). Using neutrality tests based on the allele frequency spectrum and long-range linkage disequilibrium, we detected strong signatures of recent positive selection in eastern African populations and the Fulani from central Africa. In addition, haplotype analysis supported an eastern African origin of the C-14010 LP-associated mutation in southern Africa.

The paper constitutes part of a long-range series aiming, step by step, to identify the inherited Afro-Asiatic stock in the etymologically little explored lexicon of the Omotic (West Ethiopia) branch of the Afro-Asiatic family displaying the least of shared traits among the six branches of this macrofamily, which suggests a most ancient Omotic desintegration reaching far back to the age of post-Natufian neolithic.
