The Meaning of Evolution (1951) PDF by George Gaylord Simpson

The Meaning of Evolution (A Special Revised and Abridged Edition) 

The Meaning of Evolution

This is a profound and stimulating study of the entire span of life on earth, written by a leading scientist, Dr George Gaylord Simpson, chairman of the Department of Geology and Paleontology at the American Museum of Natural History. Dr Simpson answers, simply and straightforwardly, the fundamental questions about the evolution of life and its meaning in terms of man’s nature, ethical standards and destiny.

The present book is an abridgement and revision of “ The Meaning of Evolution: A Study of the History of Life and of its Significance for Man,” published by Yale University Press, to which the reader is referred for a more complete discussion of certain points than is possible in this shorter book. That book was an expansion of the twenty-fifth series of Terry Lectures, delivered by the author at Yale University. Thanks are due to the Dwight Harrington Terry Foundation and to Yale University Press for the opportunity to present “The Meaning of Evolution” to the public and now to present a shortened and somewhat altered version of it to a still wider audience.
