Near fine hardcover, shelf wear to dust jacket. The theory of animal evolution is usually illustrated by examples from skeletons in museums, and most writers still keep to the examples of a century ago. The present author has used, instead, the waterfowl which can be seen walking about. The book is written in simple language and intended for both those studying biology and amateur naturalists. Illustrations by Robert Gillmor illustrate the main points. Very good paperback.
