Question

Why do people from some countries have different coloured skin?

Answer

Skin colour is related to the amount of melanin in skin cells; melanin in turn absorbs UV light from the sun, so roughly speaking, people who have evolved in areas of the world with intense sunlight will have more melanin. ironically here in Canada, our issue is as much not getting ENOUGH sunlight in the winter to manufacture Vitamin D.
