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 higher levels of UV radiation can lead to the breakdown of folate, an essential nutrient, whereas lighter skin pigmentation allows for more effective synthesis of Vitamin D in lower UV environments.
