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 largely due to the need for adequate Vitamin D synthesis in areas with lower UV radiation levels, which favored individuals with reduced pigmentation.
