　　托福阅读词汇题：undisputed

　　【Paragraph 4】Contrary to the arguments of some that much of the pacific was settled by Polynesians accidentally　marooned after being lost and adrift, it seems reasonable that this feat was accomplished by deliberate colonization　expeditions that set out fully stocked with food and domesticated plants and animals. Detailed studies of the winds and　currents using computer simulations suggest that drifting canoes would have been a most unlikely means of colonizing　the Pacific. These expeditions were likely driven by population growth and political dynamics on the home islands, as　well as the challenge and excitement of exploring unknown waters. Because all Polynesians, Micronesians, and manyMelanesians speak Austronesian languages and grow crops derived from Southeast Asia, all these peoples most　certainly derived from that region and not the New World or elsewhere. The undisputed pre-Columbian presence in　Oceania of the sweet potato, which is a New World domesticate, has sometimes been used to support Heyerdahl’s “American Indians in the Pacific” theories. However, this is one plant out of a long list of Southeast Asian domesticates.As Patrick Kirch, an American anthropologist, points out, rather than being brought by rafting South Americans, sweet　potatoes might just have easily been brought back by returning Polynesian navigators who could have reached the west　coast of South America.(The Origin of the Pacific Island People)
