World Trade and Biological Exchanges before 1492

This book by John L. Sorenson (emeritus professor of anthropology at Brigham Young University) and Carl L. Johannessen (emeritus professor of geography at the University of Oregon) presents a comprehensive, well-referenced, and intriguing overview of historical and archeological evidence for pre-Columbian exchange of plants, microfauna, and animals between the Old and New Worlds. Its style is more encyclopedic than narrative, resembling an expanded, annotated bibliography. I read with interest the sections dealing with the crops that I have researched genetically—Amaranthus and Chenopodium—as well as several other crops that I am very familiar with, such as cotton.
