H. Why did the cultures of ancient Mesopotamia, Egypt, and India NOT develop in isolation

Explanation:

These cultures have learned a lot from being with other people that are not of their culture. This basically means that, for example, when the wheel was invented in ancient Mesopotamia, other cultures found it useful and adapted the idea to fit their own specific needs. These cultures you listed could not have been as powerful if they stayed to themselves in isolation. But because they did venture out and fight and learn, they have become what they are.
