Pre History

World History - Prehistory

The development of the people in Mesoamerica was quite similar to Paleolithic and Neolithic humans in the eastern hemisphere.

These early people developed farming and herding, arts, religion, and they built temples. Trading developed. Some tribes became very wealthy and powerful. They were cut off from others, so they developed more slowly - about 1,000 years behind the eastern hemisphere peoples.

The first people came from Asia (Bering Strait) starting about 30,000 years ago. They came in several groups - whenever the land bridge was there, and spread out. Many moved south to Central and South America. As they scattered, they developed hundreds of cultures. By 1500 BC many lived in villages.
