Which factors were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection? (1 point)

Question

• a change in the diet of human populations as they settled in colder climates
O the impact of UV radiation on folate and Vitamin D levels in human populations
O the interaction of human populations with predators in colder climates
• the clothing worn by humans in the early 8th century

Answer 1

The factor that was determined to directly cause the loss of skin pigmentation in humans as a result of natural selection is:

O the impact of UV radiation on folate and Vitamin D levels in human populations.

This relationship highlights the balance between the need for adequate Vitamin D synthesis and the protection against UV radiation, which has influenced skin pigmentation variations in different environments.
