Humans that produced less melanin became more common as populations migrated away from the equator. As populations moved further away from the equator and into regions with less UV radiation, there was less of a need for melanin to protect the skin from harmful UV radiation. Over time, certain populations developed lighter skin with less melanin. However, populations that migrated towards the equator developed more melanin to protect their skin from the strong UV radiation found in those regions.
