The factor that directly caused 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**.
In regions with high UV radiation, darker skin is beneficial as it protects against folate degradation; conversely, in areas with lower UV radiation, lighter skin allows for more efficient production of Vitamin D, which is essential for bone health and overall functioning.
