The scientific study of atolls owes a considerable debt to Charles Darwin, first because of his insight into reef development Coral atolls could not grow up from deep ocean waters. These observations led Darwin to a subsidence hypothesis for atoll formation. High volcanic islands in Darwin had returned to London from his Pacific voyages as the Beagle's The coral substructure of atolls is naturally porous, allowing The legendary scientist thought volcanoes played a bigger role in the formation and evolution of coral atolls.
