There are, however, problems with almost all aspects of this story, say Hunt and his colleague Carl Lipo of California State University in Long Beach. Take the idea that the population was once much larger than the low estimates made by early visitors. “People say, ‘Look at all these statues, there must have been armies of people to do this,'” says Lipo. Many conclude that by Roggeveen’s time the society had already collapsed. “But that is just absolute speculation,” Lipo says.
