The great islands of Polynesia are dispersed far across the pacific ocean from Hawaii to New Zealand. How did the very early Polynesians get to these places without metal tools or writing? How could they have known about these islands at all? In her book, Sea Peoples: The Puzzle of Polynesia, author Christina Thompson delves deep into these questions that have puzzled anthropologists, geographers, and others since the eightenthenth century. West Lafayette Public Library Director Nick Schenkel has the review.
