The factor that was determined to directly cause the loss of skin pigmentation in humans as a result of natural selection is the impact of UV radiation on folate and Vitamin D levels in human populations. This is because varying levels of UV radiation in different environments required adaptations in skin pigmentation to balance the production of Vitamin D while also protecting against folate depletion caused by excessive UV exposure.
