The same solution--that Easter Island was once part of a much larger landmass--would also explain another, very different puzzle, namely the so-called Rongo Rongo script. It is unprecedented in human history for a sophisticated fully developed writing system to be invented and put into use by a small, isolated island community. Yet Easter Island does have its own script, examples of which, mostly incised on wooden boards, copies of copies of copies of much older lost originals, were collected in the nineteenth century and have found their way into a number of museums around the world. None remain on Easter Island itself and even in the period when they were collected no native Easter Islanders were able to read them.
