The possibility that Polynesian seafarers made landfall and interacted with the native people of the New World before Columbus has been the topic of academic discussion for well over a century, although American archaeologists have considered the idea verboten since the 1970s. Fresh discoveries made with the aid of new technologies along with re-evaluation of longstanding but often-ignored evidence provide a stronger case than ever before for multiple prehistoric Polynesian landfalls. This book reviews the debate, evaluates theoretical trends that have discouraged consideration of trans-oceanic contacts, summarizes the historic evidence and supplements it with recent archaeological, linguistic, botanical, and physical anthropological findings. Written by leading experts in their fields, this is a must-have volume for archaeologists, historians, anthropologists and anyone else interested in the remarkable long-distance voyages made by Polynesians. The combined evidence is used to argue that that Polynesians almost certainly made landfall in southern South America on the coast of Chile, in northern South America in the vicinity of the Gulf of Guayaquil, and on the coast of southern California in North America.

The exploration and colonisation of the Pacific is a remarkable episode of human prehistory. Early sea-going explorers had no prior knowledge of Pacific geography, no documents to record their route, no metal, no instruments for measuring time and none for exploration. Forty years of modern archaeology, experimental voyages in rafts, and computer simulations of voyages have produced an enormous range of literature on this controversial and mysterious subject. This book represents a major advance in knowledge of the settlement of the Pacific by suggesting that exploration was rapid and purposeful, undertaken systematically, and that navigation methods progressively improved. Using an innovative model to establish a detailed theory of navigation, Geoffrey Irwin claims that rather than sailing randomly downwind in search of the unknown, Pacific Islanders expanded settlement by the cautious strategy of exploring upwind, so as to ease their safe return. The author has tested this hypothesis against the chronological data from archaeological investigation, with a computer simulation of demographic and exploration patterns and by sailing throughout the region himself.
