Genetic variation, overtime QuickChek

How have the historic levels of MELAININ in human populations, change due to migration
Humans that produce less MELANIN become more common as populations migrated away from the equator
Humans that produce more MELANIN become more common populations migrated towards the equator
Humans that produce less MELENIN become more common populations migrated towards the equator
Humans that produce more MELANIN become more common as populations migrated away from the equator

Overall, the historic levels of MELANIN in human populations have changed due to migration. As populations migrated away from the equator, where there is less intense sunlight, humans that produce less MELANIN became more common. On the other hand, as populations migrated towards the equator, where there is more intense sunlight, humans that produce more MELANIN become more common. This adaptation to different levels of sunlight exposure is an example of how genetic variation has played a role in human evolution over time.
