Which of the following statements are False?
  •    The general geographic patterns of skin pigmentation show a strong correlation with latitude and ultraviolet radiation (UVR) intensity.
  •    Skin pigmentation tends to be darker in equatorial and tropical regions where UVR levels are higher, than in regions distant to the equator.
  •    Dark skin has a biological advantage under high UVR to protect from UV-induced sunburn, skin cancer, immune suppression and photolysis of folate - a metabolite essential for the development of embryonic neural tube and fertility.
  •    Light skin is biologically disadvantageous even in regions far from the equator, which are exposed to lower levels of UVR.
