Analysis of African rainforest hunter-gatherers and farmers. a DNAm age versus age using 256 blood samples from [42]. The points are colored as follows: magenta = AGR (urban setting), turquoise = AGR (forest), brown = RHG (forest). Group status versus (b) universal age acceleration, (d) intrinsic age acceleration, (f) extrinsic age acceleration. Habitat versus (c) universal age acceleration, (e) intrinsic age acceleration, (g) extrinsic age acceleration. (h, i) are analogous to (a, b) but the y-axis is based on a DNAm age estimate that excluded CpG that were located near SNPs. In this robustness analysis, we removed CpG probes containing genetic variants at a frequency higher than 1 % in the populations studied
