Over the past few weeks I've been looking closely at all the skin color related genes in humans which have been studied over the past few years. A little over two years ago the evolutionary biologist Armand Leroi wrote:
We don't know what the differences are between white skin and black skin, European skin versus African skin. What I mean is we don't know what the genetic basis of that is. This is actually amazing. I mean, here's a trait, trivial as it may be, about which wars have been fought, which is one of the great fault lines in society, around which people construct their identities as nothing else. And yet we haven't the foggiest idea what the genetic basis of this is. It's amazing. Why is that?
Armand wrote that in the spring of 2005. In December of that year a paper was published in Science, SLC24A5, a ...
