    Abstract

    The idea that American Indians played no part in Polynesian prehistory originated with J.R. Forster, a companion of Cook on his second voyage. Forster made a comparative study of five Polynesian languages, using a basic list of 40 words that included 'sweet potato'. He concluded that although there were many similarities between those languages and the languages of Southeast Asia, 'no distant or accidental similarity' existed between the Polynesian and American languages. Moreover, the 'wretchedness and small size' of American sailing craft proved 'incontestably' that the Pacific Islanders had not originated in the Americas. The premises for Forster's claims have long been proved to be wrong. Yet many scholars still accept his main conclusion. This article contraverts that view. It argues that voyagers from Mindanao crossed the Pacific to Ecuador in about 200 BC on a bamboo raft and that this became the prototype of the balsa rafts of Ecuador and Peru of early Spanish times. Such rafts made prehistoric voyages to Mexico, south-central Chile, and the Galapagos Islands. Easter Island's first settlers, it is argued, were drifted there in a balsa raft. A new claim that Polynesians from Easter Island sailed to South America and returned with the sweet potato and bottle gourd is also discussed.
