…is because evolution protected our skin…

“Skin colour map (indigenous people). The twin role played by the skin – protection from excessive UV radiation and absorption of enough sunlight to trigger the production of vitamin D – means that people living in the lower latitudes, close to the Equator, with intense UV radiation, have developed darker skin to protect them from the damaging effects of UV radiation. In contrast, those living in the higher latitudes, closer to the Poles, have developed fair skin to maximize vitamin D production.”

What about eskimos? They have dark skin, AND live in what, according to that map, should make them the whitest of the white.
Um… Chinese skin is’t really that colour. I’m sure of this because my grandma is a pure blood Chinese. I’m talking about the pinker part in the middle of Asia.
