Though populated by numerous indigenous peoples, the pre-Columbian “new world” was geographically isolated from more advanced European civilization.

For 200 million years prior to Columbus’ famous expedition in 1492, the Americas had completely different flora and fauna from the rest of the world. Charles C. Mann’s new book, 1493, chronicles the “ecological imperialism” of European conquests. Using DNA testing, mathematical simulations and other modern technological tools, Mann explores the monumental biological, ecological, political and social changes that exploration and colonization had on both continents.
