This was due, then, to the fact that the concept of go north to cold is wrong. This is ignorance again typical of the educational fallacies. We can also look at the colors on the map and compare them with the colors of men's skins. The map temperature colors have to do with the radiation, the inhibition of energy from the sun. As we get into the great cold areas, the skin gets very, very white.
Men have to hibernate a great deal of the time.
In other parts of the world they could be naked with a great deal of sun. The colors of the map are related, then, also to the color of pigmentation of the skins. If there are any special differences in the shapes of noses or heights of men, it has to do very much with the long isolation of men and the developing of certain amounts of hybridism in relation to adapting to special local conditions. There are some dark-skinned people up in the Arctic among the Eskimos, and they are people who came there relatively recently from the tropics and Japan, from the darker regions, by water. They are water people.
