Why do humans varies in skin tones? Will there be 2 human that shares the exact same pigment color?
In: Other
Skin tone varies with the amount of blood flow in the upper layers of skin, the amount of melanin pigment deposit in the skin, and also other pigments from diet (like carotene, orange cued, from carrots /other vegetables).
Within a error margin, 2 human might share the exact same pigmentation, I would say.
