Melanin is the pigment which helps our skin to be defensive against over exposure. Normally when you are exposed to sun light the skin will produce melanin automatically. But people from cold climates won't need melanin as the sun light is not strong over there. So people from colder area tend to be white. But people from hotter climates need melanin to prevent sun burn so their body is programmed to do so. More melanin means the darker the skin. The reason why melanin turns our skin to black is, black color can absorb the light, but white will reflect the light. If the light is being reflected only the skin will be exposed to heat and that will damage the skin which is sunburn. But dark skin will absorb the heat and transfer the heat to the inner body parts under the skin and thus by having less damage on the skin.

Skin color is determined by the amount of melanin you have. People with more melanin are darker and those with less are whiter.As humans evolved in Africa it is thought that we were all originally dark skinned because dark skin helps to protect against the sun and skin cancer. As humans spread to other parts of the world the dark skin was not needed as much, so melanin became less important to survival. So in colder countries people developed lighter skins as they did not face the same pressure to protect themselves from the sun.Spending time in the sun causes your body to make more melanin and makes your skin darker giving you a tan.People's skin colours are different because of where they live. Generally, people who are black originally came from very hot countries. They're skin developed in reaction to the environment.
