Abstract
Recent New World archaeoparasitological discoveries of hookworm in pre-European contexts have revived a long-standing debate about the origin of hookworms in the Americas. Historically, the climatic conditions of Beringia encountered by migrating people have been considered too harsh for tropical hookworms to survive, suggesting that hookworms must have been introduced into South America by ‘storm-tossed’ fisherman or explorers from Asia. Here, John Hawdon and Susan Johnston review the history of hookworms in the Americas, and propose an alternative to their trans-Pacific introduction based on the unique natural history of one of the human hookworms.
