Question
Why do we see a change in human skin pigment in populations that are farther away from the equator?(1 point)
Responses
Humans exposed to less UV light required less melanin to make more vitamin D for healthier bones.

The correct response is:
**Humans exposed to less UV light required less melanin to make more vitamin D for healthier bones.**
This explanation aligns with the understanding of how melanin production in human skin is influenced by UV radiation exposure. In regions farther from the equator, where UV light is less intense, lower melanin levels can facilitate the synthesis of vitamin D in the skin, which is essential for bone health.
