OCA2
razib | March 4, 2010Over the history of this weblog I have blogged about pigmentation a fair amount. The major reason is that that's where the money is; unlike height, let alone intelligence, the genetic architecture and evolutionary history of pigmentation has been elucidated with relative clarity. That is, we know roughly the number and nature of the genes which control much of the between population variation in pigmentation. And, we also have some sense of whether the variation is due to natural selection, as well the historical trajectory of the between population differences.
For example, consider the…
