@atlasoffaces: Nearly everyone with blue eyes carries the same small change next to a pigment gene, and ancient DNA has found it in hunters in Italy and the Caucasus 13,000 to 14,000 years ago. Western Europe's hunter-gatherers probably had dark skin and light eyes; lighter skin spread later with farmers from Anatolia. Today the variant is in about 9 in 10 gene copies in a Finnish sample and none in Japanese or Nigerian samples. The portraits are AI illustrations. Sources: Eiberg et al. (2008), Sturm et al.
