There isn't much desire to run the 100 in Eskimo culture.
I assume you chose the Chinese because they are a developing civilization and appear to be quite intelligent, and I also assume you chose the Aboriginees of Australia because they appear to do nothing but play with rocks or something like that (no heavy thinking).
If you take a chinese newborn and take him to live with the Aboriginees and you take a baby from Austrailia and raise him in China, what will the outcome be?
I think intelligence is fostered and groomed from day one, and if you are in a society like China, where you need a strong brain to survive, the child will come out smarter and able to solve problems.
If all you teach the child to do is gather food and fight, I don't think he will do very well with a spelling test.

Why do Norway, Sweden, Canada and theSoviets tend to excell at winter athletics, while Jamaica doesn't(see the Cool Runnings reference?)? Is it genetic, or is it simply because the culture of one area emphasizes those sprots for obvious reasons, while Jaimaca, also for obvious reasons, doesn't?
Are people from Africa created differently genetically? Maybe it is because they run from the time they are very young and it keep their bodies in great condition.
Why would you ask the question like it is not possible?
