The collapse of the once thriving human population on Easter Island has been largely attributed to environmental degradation, but questions still remain regarding the causative factors. Our study will determine the sequence and timing of the collapse of humans, seabirds, forest trees and soils by detailed dating and analysis of sediment cores from bogs for DNA, pollen, charcoal, soot, and fecal steroids.
