    "Neanderthal Origin of the Haplotypes Carrying the Functional Variant Val92Met in the MC1R in Modern Humans

    Qiliang Ding et al.

    Skin color is one of the most visible and important phenotypes of modern humans. Melanocyte-stimulating hormone and its receptor played an important role in regulating skin color. In this paper, we present evidence of Neanderthal introgression encompassing the melanocyte-stimulating hormone receptor gene MC1R. The haplotypes from Neanderthal introgression diverged with the Altai Neanderthal 103.3 KYA, which postdates the anatomically modern human – Neanderthal divergence. We further discovered that all of the putative Neanderthal introgressive haplotypes carry the Val92Met variant, a loss-of-function variant in MC1R that is associated with multiple dermatological traits including skin color and photoaging. Frequency of this Neanderthal introgression is low in Europeans (~5%), moderate in continental East Asians (~30%), and high in Taiwanese aborigines (60-70%). Since the putative Neanderthal introgressive haplotypes carry a loss-of-function variant that could alter the function of MC1R and is associated with multiple traits related to skin color, we speculate that the Neanderthal introgression may have played an important role in the local adaptation of Eurasians to sunlight intensity."

    This refers to skin color in Taiwanese aborigines, not to hair color in Europeans.

      I think that the variant Val92Met is common in western Europeans with red hair, light skin and blue or green eyes.
      One of the reasons for these common traits in Ireland and Scotland is the amount of cloud cover.
