Take African skin, especially around the equator where UV rays are particularly strong. Those with the darker skin would have a protection advantage and would have mated with darker skined mates. ( sexual selection? ) Those of the far north would not have near the UV problem, but would perhaps need light skin in the far north to take in enough light to promote vitamin D production. It is all about variation in populations and selection for those traits that confer reproductive advantage for individuals and evolution for populations who inherit these traits.

Humans have different skin colors due to variations in the amount of melanin produced by melanocytes in the skin.

This variation in skin color is an adaptation to different levels of sun exposure in different regions of the world.

They don't. Skin colour is an adaptation to climate, and not an indicator of race. Race is not a biological concept, but it is determined by skeletal size. For instance, Arabs and British are both the same race (Caucasoid), but their skin colour is different as they live in different environments.
