Study Description

To investigate how human populations have adapted to the equatorial rainforest, we generated 266 high-coverage exomes, analyzed in combination with 300 published exomes, from 14 populations of African rainforest hunter-gatherers and farmers, together with 40 newly-generated, low-coverage genomes. Genome scans for positive selection and signatures of polygenic selection provide evidence for local adaptation of hunter-gatherers to the African rainforest.

Dataset ID Description Technology Samples
Exome sequencing of 277 rainforest hunter-gatherers (RHG) and neighbouring farmers (AGR) from Central Africa was performed based on the Nextera Rapid Capture Expanded Exome Kit (62-Mb content) with the Illumina HiSeq 2500. After QC filters, exomes of 266 unrelated individuals were obtained at high coverage (Lopez et al., Curr Biol 2019).
Illumina HiSeq 2500 277
Exome sequencing of 20 rainforest hunter-gatherers (RHG) and 20 neighbouring farmers (AGR) from western central Africa was performed using 101-bp paired-end reads on Illumina HiSeq 2000. All individuals presented very low rates of missing values ranging from 0.5% to 4%, and a mean depth of coverage of 6.5× (ranging from 4× to 13×)(Lopez et al., Curr Biol 2019).
