We see this in African-Americans, because the sun is extremely hot in Africa all year long. This genetic adaptation of their skin helps them to survive under very hot days under the African sun. Secondly, long term physiological adaptations are people who grow up in country close to the equator. These people may burn at first, but eventually their skin will adapt and they will start to tan after being exposed to the sun for long periods of time. The short term effects of humans under extreme ultraviolet light would simply be to burn, which protects their epidermis from being damage. Culturally humans adapt to ultraviolet light with different types of protection. An example would ...
