Alfred Russel Wallace (1823-1913) the codiscoverer of the theory of evolution, is the fascinating subject of this comprehensive modern biography. A great explorer, discoverer of species, theoretical biologist, and a good friend of Darwin's, he always deferred to the knowledge and experimental skill of his contemporary. His life was more exciting, diverse, and as productive as Darwin's. An odd personality who curiously insisted that the discovery of evolution was Darwin's only who dabbled in later years with spiritualism, he spent many years exploring the Amazon and East Indies regions. The modern science of zoography was his creation. He did important work on glaciation, protective coloration, mimicry, distribution of animals, and the origin of language. His life and works are surveyed in interesting detail by the author who makes clear his importance as a stimulus to Darwin and as a significant natural scientist. There are particularly useful summaries of his ideas as they appeared. Includes chronologies of his Amazon and Malaya Archipelago trips and a bibliography listing some 85 of his most important publications. A valuable addition to any natural history collection.
