Book excerpt: This book synthesizes existing knowledge of the process of domestication and how domestication has affected the behavior of captive wild and domesticated animals, including both farm, zoo and companion animals. Three broad themes are addressed: Genetic contributions to the process of domestication; experimental contributions to the process of domestication; and the process of feralization (i.e. the adaptation of domesticated animals when returned to their natural habitat). Written by a world authority on the subject, this book makes a highly original contribution to the literature.
