People in sunnier climates tend to get more ultraviolet exposure.
They therefore have developed darker skins since melanin (which
makes the skin darker or tanner) is the major defense against
UV that the skin has.

This sounds Lysenko-ist, but you can make a straight evolutionary
argument by noting that people with darker skin are less likely
to get skin cancer.
