*Human skin color* is primarily due to
*melanin<http://en.wikipedia.org/wiki/Melanin>
*, it ranges from skin almost black in appearance to white with a pinkish
tinge due to blood vessels <http://en.wikipedia.org/wiki/Blood_vessels>
 underneath.[1]
<http://en.wikipedia.org/wiki/Human_skin_color#cite_note-0> Variations
in skin color are mainly of genetic origin and are associated with sunlight
but the evolutionary causes are not completely certain, the leading
explanation is they are adaptations to sunlight intensities which
produce vitamin
D <http://en.wikipedia.org/wiki/Vitamin_D> deficiency or
ultraviolet<http://en.wikipedia.org/wiki/Ultraviolet> light
damage to folic acid
<http://en.wikipedia.org/wiki/Folic_acid>.[2]<http://en.wikipedia.org/wiki/Human_skin_color#cite_note-1>
Other
hypotheses include protection from ambient temperature, infections, skin
cancer <http://en.wikipedia.org/wiki/Skin_cancer> or
frostbite<http://en.wikipedia.org/wiki/Frostbite>,
an alteration in food, and sexual
selection<http://en.wikipedia.org/wiki/Sexual_selection>
