Black white and all the other skin colors are the result of evolution. Evolution changes a species for survivability not for aesthetics. One consideration is that pale skinned peoples come from northern regions where there is not much sun, Sunlight is necessary for the formation of vitamin D in the body. A lighter skin would allow this formation to occur more rapidly in the weak sunlight (especially when the major part of the body was bundled up against the cold). As a consequence the northern peoples may have mutated to favor lighter skins than mankind's original color.

---------------------

I agree, since it is clear that the cradle of humanity is tropical Africa, all human groups probably started out with a darker skin color. This could have been altered over many generations in areas and times where lighter skin became a survival factor (as in colder climates, Ice Ages).
