Era 3 was a period of great change and innovation. In many places, the development of farming contributed to new types of communities and long-distance networks. But we don't entirely understand how (or even where and when) these changes happened. We can begin to explore these transformations through two pieces of evidence: a case study of Tapajos in the Amazon rainforest, and data on the emergence of cities around the world.
