    Those are definitely reasonable explanations, especially since you do get more vitamin D w/ less sun the lighter your skin is - and there are trade-offs when you get a lot of sun with light skin. Though the story could also be more complex or even seemingly random (or just historically contingent), also having to do with how people migrated, how big their populations got, etc etc.
