Species

"Few topics have engaged biologists and philosophers more than the concept of species, and arguably no idea is more important for evolutionary science. John S. Wilkins' book combines meticulous historical and philosophical analysis and thus provides new insights on the development of this most enduring of subjects."--Joel Cracraft, American Museum of Natural History

"This is not the potted history that one usually finds in texts and review articles. It is a fresh look at the history of a field central to biology, but one whose centrality has changed in scope over the centuries. Wilkins' book will be a standard source for all kinds of people working in systematics. There is not another book on the subject, amazingly enough, and his perspective is so comprehensive and well-taught that it will replace any standard review articles and older histories."--Kevin Padian, University of California, Berkeley

"An essential sourcebook for anyone interested in the species problem and the history of 'species.' Wilkins does a wonderful job detangling the various uses of 'species.' His book brings clarity to a topic marked by confusion and ambiguity."--Marc Ereshefsky, author of The Poverty of Linnaean Hierarchy: A Philosophical Study of Biological Taxonomy

John S. Wilkins is Research Fellow in Philosophy at the University of Sydney. He is the author of Defining Species: A Sourcebook from Antiquity to Today.
