What causes different skin colours?

Answer 1

Yes, melanin is the primary pigment responsible for differing skin color, including tanning. It does provide protection against ultraviolet radiation. See the human skin color map in the reference. The darkest skin is found in the equatorial regions with the highest incident ultraviolet radiation. Skin is lighter at higher latitudes, for two reasons. Less protection is needed against ultraviolet radiation. Further, you don't want melanin interfering with the absorbtion of UV, since that is the primary source of vitamin D3 for the body.

Answer 3

Melanin: A skin pigment (substance that gives the skin its color). Dark-skinned people have more melanin than light- skinned people. Melanin also acts as a sunscreen and protects the skin from ultraviolet light.

Melanin is produced by cells called melanocytes. It provides some protection again skin damage from the sun, and the melanocytes increase their production of melanin in response to sun exposure. Freckles, which occur in people of all races, are small, concentrated areas of increased melanin production.

this may be due to:
1.climatic conditions they live .like in africa people are dark skinned because the climatic conditions there is invariably high and it is a kind of adaptation their skin makes to escape heat . (negros)
2. high production of melanin protein that gives colour to skin.
variable climatic condition varies melanin content.
in USA and northern countries the climatic conditions are not invariable so melanin production is low thus they are called albinos.

Answer 6
