The dark skin comes from a compound called Melanin and it is a sort of built in sun screen. Blacks are VERY rarely known to suffer from Skin Cancer but could potentially suffer from Vitaimin D deficiency without direct contact with sunlight in an an area with very little sunlight like black sailors on a submarine, blacks in arctic climates where the days are very short and majority of time is spent indoors because of the climate. Melanin historically has protected the people from damage from the suns rays.

Evolution! Look it up...White people are descended from Black people....First there were Black people and as humans migrated all over, they migrated to northern lands where there wasn't alot of sun so their skin got lighter and their bodies changed...Evoultion...BTW...I am white and hispanic!
The most fundamental reason for skin color differences is the fact that humans live at different latitudes. It is quite obvious that humans that have lived in equatorial areas for many many generations tend to have darker skin. As one moves from equatorial Africa toward the north there is a constant change in skin color. By the time you get to northern Scandinavia you have very light skinned people with blond hair and blue eyes, while people living near the equator have black skin, black eyes, and black hair. This is easy to understand. Take two tin cans and paint one black and the other white. Fill them with boiling water and measure their temperature five minutes later. Dark colors radiate heat faster than light ones, so the darker can will be cooler than the white one. In Africa the problems of heat release are very large. The brain cannot be allowed to overheat, and getting rid of the heat is critical

Their ancestors came from a hot country with lots of sun. Dark skin helps
protect you from the sun's rays. It's natural.

That's like asking white people why they have light skin. It's the way God made you and your DNA!

Most African Americans have a variety of skin tones and it's called a complexion idiot.
