Julius Mulindwa et al (2017)
Genomic evidence for population specific selection in Nilo-Saharan and Niger-Congo linguistic groups in Africa.
BioRxiv preprint
A majority team of Africans authored this study. Their affiliated institutions are in
• Uganda
• Burkina Faso
• Côte d'Ivoire
• Democratic Republic of the Congo
• Cameroon
• Malawi
• Zambia
• Guinea.
No precise information indicating their exact roles (text, sample collection, or
sequence facilitation, etc.)
They accept the major language classifications as in Blench, Greenberg, and Lewis.
Also Bryc, Tishkoff and Williams, Gurdasani, Busby, and Patin on genetic variation.
This study uses no less than 26 and up to 50 individuals from each ethno-linguistic
group considered. Whole genome sequencing was derived from over 30 million
SNPs with over 2 million new rsIDs uncovered. Sleeping sickness, malaria, HIV,
and tuberculosis related genes are a focus of this study which also offers a post-
LGAM (Last Glacial - Arid Maximum) migration map for Niger-Congo speakers.
Unfortunately the map neglects the fact people were living in western Africa before the
LGAM and their impact on trans-Sahelian migration even though, imho, detectable from
K=4 (yellow) on their ADMIXTURE plot.
But let me save analysis and critique for later posts.
