Quizplus · Accepted Answer

Skin color is influenced by the balance between the need to block harmful UV radiation, which destroys folate, and the need to absorb sunlight to synthesize vitamin D. In regions where UV radiation is intense, people have darker skin to protect against folate destruction, while in areas with lower UV radiation, people have lighter skin to allow sufficient vitamin D synthesis. This hypothesis is supported by studies that found a negative correlation between skin pigmentation and latitude.
