Ecological Imperialism: The Biological Expansion of Europe, 900-1900 (Studies in Environment and History)

People of European descent form the bulk of the population in most of the temperate zones of the world - North America, Australia and New Zealand. The military successes of European imperialism are easy to explain; in many cases they were a matter of firearms against spears. But as Alfred Crosby explains in his highly original and fascinating book, the Europeans' displacement and replacement of the native peoples in the temperate zones was more a matter of biology than of military conquest.
