Human skin color is the result of the pigment melanin, which has a role in protecting against high amounts of UV light. Multiple genes are involved in determining the type and amount of melanin produced. Within the modern human population, there is a large amount of variation in skin color.

Which of the following is the source of variation in human skin color?

A

Changes in environment throughout history.

B

Genetic drift occurring during bottleneck events.

C

Human migrations to different environments.

D

Mutations to the genes that code for the proteins determining skin color.
