I believe that it has to do with melanin, the part that gives skin color. People who came from areas close to the equator needed protection from ultraviolet rays and vitamin D overdose (the sunshine vitamin) which can really screw up your bones. When the dark people of Africa moved to the north of Europe and Asia, the pigment grew less so that these folks did not die of rickets caused by a lack of vitamin D, caused by the lack of exposure to sunshine (less sunshine, more wearing of skins to keep warm). This also cut down the protection from damage by the ultraviolet rays. That damage can lead to cancer. You might have also noticed that black folks don't spend a lot of time toasting in the sun trying to get a tan. go figure.

Melanin is the one that causes skin darkening. However it protects the skin from the harmful Ultra-Violet rays. Since african american people have darker complexion than Caucasian people, they have higher melanin content which means they have more protection against the UV rays that causes cancer.

the skin color tells you that you are best to stay indoors during days thus best to stay outside during the night.. black people is best to stay outdoors during days thus best to stay indoors during nights. people in between are comfortable in both ways as long as they aren't over doing it.
it isa sign of capability. caucasians are actually weak people towards the sun.

Attracting more ultra-violet rays? Lighter complexion as opposed to darker complexion.

Because they don't need to lay in the sun to get tanned.

against sunlight radiation.
furthermore,they dont have the desire,in baking on the beach. ect
