“In general, people with ancestors from tropical regions and higher altitudes (who were hence exposed to greater ultraviolet radiation) have darker skin than people with ancestors from middle latitudes. This is far from a hard and fast rule, however, because many light-skinned groups have managed to survive at the equator through social adaptation. The same can be said of dark-skinned groups living at subtropical and temperate latitudes.” “Environmental factors: In attempting to discover the mechanisms that have generated such a wide variation in human skin tone, Jablonski and Chaplin discovered that there is a high correlation between the tone of human skin of indigenous peoples and the average annual ultraviolet (UV) radiation available for skin exposure where the indigenous peoples live. Accordingly, Jablonski and Chaplin plotted the skin tone (W) of indigenous peoples who have stayed in the same geographical area for the last 500 years versus the annual UV available for skin exposu
