Not much on the face of things.
Easter Island is a tiny, remote atoll in the Pacific Ocean.
From the island, you'd have to sail over 1000 miles in any direction to reach another place inhabited by humans. European explorers who stumbled across the island, including Captain James Cook, didn't stay long. What they discovered was a small group of natives eking out a living on a desolate windswept island, surrounded by hundreds of mysterious stone statues. Cook asked questions that have been echoed by others over the past few centuries. With no written records, and oral history being somewhat unreliable, the answers would have to be provided by science.
