 Fig. 34-5. The flux of UV light from the sun almost perfectly matches the skin colour of the people who have lived there for a long time (fromJablonsky/Chaplin). What Does "Related" Mean? www.andaman.org/book/chapter34/text34.htm |

According to this, wouldn't North American Indians and Eskimos have very light skin?

Pale skin is advantegeous in synthesizing vitamin d in climates without much sunlight. However diets high in fish take care of the vitamin d needs as well. So its hypothesised that truly fair skin as seen in northern europeans devolped in areas of central europe were there were very little marine resources. Native americans probably have never had the same set of selective pressures. And inuit have diets especialy high in fish plus the need of high melanin to protect them from the intensity of snow glare. At least thats my understanding.
