Building on the startling revelations of 1421, iconic historian Gavin Menzies explores the possibility that mankind made transcontinental voyages centuries before the supposed discoveries of European explorers. With meticulous research and an adventurer's spirit, Menzies has uncovered astounding new evidence that calls into question everything about mankind's peopling of the American continents - from theories of ancient man's initial migration there to Columbus's fateful voyage. Traveling to the far-flung reaches of the earth, Menzies offers a revolutionary new alternative to the Beringia theory of how the human race crossed a land bridge connecting Asia and North America during the last Ice Age; in truth, ancient seafaring voyages had brought travelers to the Americas thousands of years prior. Who Discovered America? is a fascinating new account with astonishing implications for the history of all mankind.
