I'm not saying vitamin D isn't involved; I'm just wondering whether it's the whole story. Is this single nucleotide change in SLC24A5 really the only way to decrease melanin production without having other harmful side effects? Naively I would expect lots of ways to have a loss-of-function mutation; why is this one so common? Sexual selection could be a factor, but that is not politically correct to say.
