During and after his voyage, Darwin constructed a theory for reef formation that explained how fringing reefs grow into barrier reefs, which then convert into atolls. “The close similarity in form, dimensions, structure, and relative position between fringing and encircling barrier-reefs, and between these latter and atolls,” he wrote, “is the necessary result of the transformation, during subsidence, of the one class into the other. On this view, the three classes of reefs ought to graduate into each other.” Continue reading
