Ancient Voyages Across the Ocean to America from “Impossible” to “Certain”

In the past, experts have assumed that primitive sailors would have found it impossible to cross the oceans between the Old World and the New. However, John Sorenson here concludes that the evidence for transoceanic contacts now drowns out the arguments of those who have seen the New World as an isolated island until ad 1492. Sorenson’s arguments are based on evidences from Europe, Asia, and Polynesia of the diffusion of New World plants and infectious organisms. His research identifies evidence for transoceanic exchanges of 98 plant species, including tobacco and peanuts. The presence of hookworm in both the Americas and the Old World before Columbus also serves as evidence to establish transoceanic contact. Title
