Pre-Columbian Trans-Oceanic Contact examines the discovery and settlement of The New World hundreds and even thousands of years before Christopher Columbus was born.

Paints a compelling picture of impressive pre-Columbian cultures and Old World civilizations that, contrary to many prevailing notions, were not isolated from one another In Ancient Ocean Crossings: Reconsidering the Case for Contacts with the Pre-Columbian Americas, Stephen Jett encourages readers to reevaluate the common belief that there was no significant interchange between the chiefdoms and civilizations of Eurasia and Africa and peoples who occupied the alleged terra incognita beyond the great oceans. More than a hundred centuries separate the time that Ice Age hunters are conventionally thought to have crossed a land bridge from Asia into North America and the arrival of Columbus in the Bahamas in 1492. Traditional belief has long held that earth’s two hemispheres were essentially cut off from one another as a result of the post-Pleistocene meltwater-fed rising oceans that covered that bridge. The oceans, along with arctic climates and daunting terrestrial distances, formed impermeable barriers to interhemispheric communication. This viewpoint implies that the cultures of the Old World and those of the Americas developed independently. Drawing on abundant and concrete evidence to support his theory for significant pre-Columbian contacts, Jett suggests that many ancient peoples had both the seafaring capabilities and the motives to cross the oceans and, in fact, did so repeatedly and with great impact. His deep and broad work synthesizes information and ideas from archaeology, geography, linguistics, climatology, oceanography, ethnobotany, genetics, medicine, and the history of navigation and seafaring, making an innovative and persuasive multidisciplinary case for a new understanding of human societies and their diffuse but interconnected development.

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.

Alice Kehoe uses critical analysis of large bodies of interdisciplinary evidence to help scholars and students reevaluate the highly controversial theory that people sailed large distances across oceans in ancient times.

People moved into America very early across the Bering Strait. By the fifth millennia B.C.E. tropical sailors brought diseases to America and took plants and animals in both directions. Long before Columbus, tropical sailors carefully selected crops from New World highlands and shorelines, wet and dry climates, and took them to the Old World where they were grown in appropriate environments. Medicinal and psychedelic plants were traded and maintained in Egypt and Peru during separate, 1,400-year periods. This implies that maritime trade was continuous. In this groundbreaking book, learn about: ● 84 plants that were taken from the Americas to the Old World. ● What plants and animals were brought to the Americas. ● Why world trade was essential for transfer of so many. ● Interconnectedness of civilizations had to result from world trade. ● Dating of 18 species by archaeology with radio carbon shows dispersal. ● And much more! Plants, diseases, and animals from America were distributed throughout the world, across the oceans before 1492. It is time for scientists, teachers, and students to reconsider their beliefs about the early history of civilization with World Trade and Biological Exchanges Before 1492. ABOUT THE AUTHORS: John L.

Do civilizations independently invent themselves or are they the result of cultural diffusion? The contributors to this volume do not attempt to provide a definitive answer to this contentious question, one of the most debated issues of the past century. Instead, they shift the focus from theory to reality by presenting empirical evidence on a wide range of cultural phenomena in history and prehistory, thereby demonstrating the processes whereby cultural traits are acquired and modified—the dynamics of transmission and transformation. The range of topics covered in this volume is of extraordinary breadth: the distribution of belt hooks and belts from the steppes to North and Central China; textile exchange in the third millennium B.C.; the spread of bronze metallurgy across Asia; the adaptation of complicated technologies by distant peoples; the mechanisms whereby bronze implements were used to convey political messages in East Asia; the ethnogenesis of the Turks; the complex interrelationships among migratory and settled peoples in western Central Asia during the Bronze Age; the origins of the enigmatic Chinese goddess known as Queen Mother of the West; an account of hunting with trained cheetahs; and the use of abundant botanical and zoological evidence to affirm that the Old World and the New World must have been in contact long before the fifteenth century. Rounding out the volume is a survey of the problem of modernocentrism.
