This is strikingly different from the WHGs-who have been suggested to have the specific combination of blue eyes and dark skin and EHGs-who have been suggested to be brown-eyed and light-skinned.
Relatively dark skin pigmentation in Early Upper Paleolithic Europe would be consistent with those populations being relatively poorly adapted to high-latitude conditions as a result of having recently migrated from lower latitudes. On the other hand, although we have shown that these populations carried few of the light pigmentation alleles that are segregating in present-day Europe, they may have carried different alleles that we cannot now detect.
On the basis of coalescent analysis with sequence data from the Simons Genomic Diversity Project (SGDP), the time to most recent common ancestor (TMRCA) of most Eurasian lineages containing the rs1426654 (A) allele is 29 thousand years ago (ka) [95% critical interval (CI), 28 to 31 ka], consistent with previous studies.
A separate observation that the offspring of migrants with dark skin who migrate to cold climates have an increased risk of schizophrenia may also be due to low vitamin D during gestation and early life as dark skin requires greater sunlight exposure to make adequate levels of the vitamin D prehormone.

the Toubou have ~30% Eurasian ancestry from a population similar to the Greeks, who have 13% derived alleles at rs4988235, suggesting an expectation of ~3.9% of the derived allele simply from admixture. We similarly found in the Toubou signals at HERC2 (MIM: 605837) rs1129038 a major contributor to blue eye color in Europeans35 (Toubou derived allele frequency [DAF] ¼ 0.014; Greek DAF ¼ 0.33; Yoruba, Sara, and Laal DAF ¼ 0), as well as a signal at SLC24A5 (MIM: 609802) rs1834640, a major contributor to pigmentation36 (Toubou DAF ¼ 0.19; Greek DAF ¼ 0.99; Yoruba, Sara, and Laal DAF ¼ 0–0.04).
