1491: New Revelations of the Americas Before Columbus

In a book that startles and persuades, Mann reveals how a new generation of researchers equipped with novel scientific techniques came to previously unheard-of conclusions. Among them:

• In 1491 there were probably more people living in the Americas than in Europe.
• Certain cities - such as Tenochtitlán, the Aztec capital - were far greater in population than any contemporary European city. Furthermore, Tenochtitlán, unlike any capital in Europe at that time, had running water, beautiful botanical gardens, and immaculately clean streets.
• The earliest cities in the Western Hemisphere were thriving before the Egyptians built the great pyramids.
• Pre-Columbian Indians in Mexico developed corn by a breeding process so sophisticated that the journal Science recently described it as "man's first, and perhaps the greatest, feat of genetic engineering".
• Amazonian Indians learned how to farm the rain forest without destroying it - a process scientists are studying today in the hope of regaining this lost knowledge.
• Native Americans transformed their land so completely that Europeans arrived in a hemisphere already massively "landscaped" by human beings.
