Very informative and fascinating. I did not realize that the American Indians were so on par technologically with the Europeans at the time that the America’s were settled. The book does seem to bounce around since it does not really address things chronologically or regionally. It also does not do as good of a job as it should addressing the Native Americans in the United States and Canada focusing heavily on the Aztecs, Mayans, and Incans. It is still easily worth listening to even given the length.
