Evolution by Association : A History of Symbiosis

Our Evolution and that of all plants and animals is not due solely to the gradual accumulation of gene changes within species. We evolved from, and are comprised of, a merger of two or more different kinds of organisms living together. Symbiosis is at the very root of our being. This book is an assembled systematic history of this emerging field and gives a wide-ranging account of the growth of an important biological idea.
