Genotyping by array of genomic variation in seven Khoe-San groups to reveal adaptation and complex African history

Project description:The history of click-speaking Khoe-San, and African populations in general, remains poorly understood. We genotyped ~2.3 million SNPs in 220 southern Africans and found that the Khoe-San diverged from other populations at least 100,000 years ago, but structure within the Khoe-San dated back to about 35,000 years ago. Genetic variation in various sub-Saharan populations did not localize the origin of modern humans to a single geographic region within Africa, instead, it indicated a history of admixture and stratification. We found evidence of adaptation targeting muscle function and immune response, potential adaptive introgression of UV-light protection, and selection predating modern human diversification involving skeletal and neurological development. These new findings illustrate the importance of African genomic diversity in understanding human evolutionary history .220 samples were analysed with the Illumina HumanOmni2.5-Quad BeadChip and are described herein.

Genome-wide Ancestry and Demographic History of African-Descendant Maroon Communities from French Guiana and Surname.

Project description:The transatlantic slave trade (TAST) was the largest forced migration in world history. However, the origins of the enslaved Africans and their admixture dynamics remain unclear. To investigate the demographic history of African-descendant Marron populations, we generated genome-wide SNP data (4.3 million markers) from 107 individuals from three African-descendant populations in South America, as well as 124 individuals from six west African populations to complement underrepresented African data sets. Our study sheds additional light on the demographic consequences of the TAST and illustrates how genetic data can complement historical sources.

Genotyping of 327 individuals from 14 populations across the Sahel/Savannah belt that were genotyped on the Illumina H3Africa Consortium Array.

Project description:The Sahel/Savannah belt harbours diverse populations with different demographic histories and different subsistence patterns. However, populations from this large African region are notably under-represented in genomic research. To investigate the population structure and adaptation history of populations from the Sahel/Savannah space, we generated dense genome-wide genotype data of 327 individuals—comprising 14 ethnolinguistic groups, including ten previously unsampled populations. DNA samples were genotyped on the Illumina H3Africa Consortium Array (BeadChip type: H3Africa_2017_20021485_A2; designed for SNP-genotyping of 2,267,346 SNPs) at the SNP&SEQ Technology Platform, NGI/SciLifeLab Genomics (Sweden).
