On the other hand, it may only prove that the solution to similar problems may come up with similar simple answers.
In virtually every area of the world where large beasts were available for taming and working, man developed wheels. I don't think anyone claims that wheels were the invention of one single culture.
However, in the Americas, where no large draft animals were available, the wheel was unknown except as a children's toy. It apparently wasn't considered as a solution to a common problem.
