The last two posts within this thread are excellent examples of the misapplication of facts and reasoning masquerading as properly reasoned arguments. Such arguments are not very far from scientific racism, an idea long since abandoned by the scientific community.
First, to destroy Shingo's credibility. While it may be true that the Inuit people and Egyptians have different noses, you have failed to provide a reason for this difference. Instead you have supposed that these differences aid them within their environments, and you completely ignore the important question, "Why do the Egyptians and Inuit have different nose sizes?"
Natural selection offers no explanation. The Egyptians do not have small noses to conserve moisture, because moisture has never been the primary handicap of Egypt. Ancient Egypt (where any changes may have taken place) was the bread-basket for the Roman Empire. No other area was as rich in farmable land. This is because Egypt was a RIVER CIVILIZATION. They lived along the banks of the Nile RIVER, that FLOODED every year. The amount of moisture that theoretically could be saved by small noses is insignificant to their environment. Since there is no reproductive benefit to a smaller nose, its existence is an anomaly.
Also, compare the Inuit to other northern ethnic groups. Say, the Finnish? I'm no expert on the population of Finland, but I'm pretty sure that one could describe the natives as "white." The Inuit are not "white." I should know; I saw some of them quite recently. Since we have two traits that are different, and traits that have measured effects on health in northern climates (production of vitamin D depends on skin coloration), it is unreasonable to think these traits were caused by the environment. They are coincidental, nothing more.
Note also that the Inuit share the same skin pigmentation as the equatorial population descended from the Maya. There should be a difference if humans have adapted physically to their environments. But there isn't.
The bush-men in Africa are not "adapted" to a life in the desert. They are malnourished. They lack the caloric intake to maintain a healthy, plump body. Feed them as much as a middle class European/American, and then you can watch them lose their slim figure quite quickly.
Any further argumentation should be in another thread or in PMs. If someone sends me a correct, factually supported contradiction of my claims, I will retract them.
