The stone heads on Easter Island are an enduring mystery: why were they built and why were they abandoned and destroyed? The old ideas about cultural collapse are yielding to new ones based on careful investigation on the ground - but also from above. What surprising explanations have we found and are we off base to think that ancient societies such as the Easter Islanders or the classical Egyptians were, in the end, failures? Can what we learn from these histories help predict which societies will survive?

Guests:

• James Grant Peterkin – Tour guide, resident, and British Honorary Consul on Easter Island
• Sarah Parcak – Archaeologist, Egyptologist, remote sensing expert, professor at the University of Alabama at Birmingham, and author of Archaeology from Space: How the Future Shapes Our Past
• Carl Lipo – Anthropologist and professor at Binghamton University, State University of New York
