We consider the human race that is spread across the globe as members of a single species, Homo sapiens, but we certainly dont all look the same. Melanin controls the amount of ultraviolet (UV) radiation from the sun that penetrates the skin by absorption. In biology, a pigment is any material in color of plant or animal cells. The emergence of skin pigmentation dates to about 1.2 million years ago,[18] under conditions of a megadrought that drove early humans into arid, open landscapes.

[81][82], The sexes also differ in how they change their skin color with age. The involved patches of skin become lighter or white. The leading theory is that skin color adapts to intense sunlight irradiation to provide partial protection against the ultraviolet fraction that produces damage and thus mutations in the DNA of the skin cells.

Neolithic farmers entering Europe at around the same time were intermediate, being nearly fixed for the derived SLC24A5 variant but only having the derived SLC45A2 allele in low frequencies. In addition, lighter skin is able to generate more vitamin D (cholecalciferol) than darker skin, so it would have represented a health benefit in reduced sunlight if there were limited sources of vitamin D.[10] Hence the leading hypothesis for the evolution of human skin color proposes that: The genetic mutations leading to light skin, though partially different among East Asians and Western Europeans,[20] suggest the two groups experienced a similar selective pressure after settlement in northern latitudes. [2] Color is not entirely uniform across an individual's skin; for example, the skin of the palm and the sole is lighter than most other skin, and this is especially noticeable in darker-skinned people.

Albinism is an extreme form of skin pigment discoloration and more specifically hypopigmentation, that causes the partial or complete loss of pigmentation in the skin, hair, and eyes due to a lack or absence of tyrosinase, the enzyme essential in the production of melanin.
