One of my favorite documentaries...absolutely astounding from beginning to end...Enjoy.
A Peruvian site previously reported as the oldest city in the Americas actually is a much larger complex of as many as 20 cities with huge pyramids and sunken plazas sprawled over three river valleys, researchers report.
Construction started about 5,000 years ago — nearly 400 years before the first pyramid was built in Egypt — at a time when most people around the world were simple hunters and gatherers, a team from Northern Illinois University and Chicago's Field Museum reports in today's issue of the journal Nature.
The society and its people — known only as the Andeans — persisted in virtually the same form for 1,200 years before they were overrun by more warlike neighbors. That is the longest time any known ancient civilization survived, according to archaeologist Jonathan Haas of the Field, who led the expedition. The results greatly expand understanding of how complex states began in the Americas. They found no evidence of military fortifications or weapons. But they did find cotton, fishing nets, and cocaine.
