The article says that we evolved to absorb more vitamin D because of a change in our diets. It would have been interesting to see what would have happened to African people who were living around the equator if they had changed their diets and needed extra vitamin D. Would they have evolved lighter skin instead of (or along with) us? And if so, what evolutionary adjustments would have been made to prevent nearly constant sunburns?
