As humans migrated out of Africa, into northern climates, that received lesser amounts of sunlight, they may have evolved lighter skin coloration, to best absorb sunlight, as a way of providing the body with Vitamin D, which is produced by the skin when the skin is exposed to sunlight.

Edit: went back to look and there was already an icon. And you didn't quote it! Talk about putting words into someone's mouth. How about you not taking words away!
