I used the second edition of this book and have not had a chance to view the third, but it no doubt is an excellent and comprehensive overview of the theory of evolution, just as in the second. In the edition I used, there are many fine diagrams illustrating the main points and also exercises at the end of each chapter to reinforce the concepts presented. Space probibits a detailed review so I will list only the areas in the book that I found exceptionally well-written: 1. The philosophical and religious issues in evolution theory. 2. The history of biology before Darwin. 3. The comparison between the pangenesis and germ plasm theories in the formation of a human. 4. The table on the comparison of views on variation and heredity. 5. The clarification determining systems. 13. The discussion on sickle cell mutation. 14. Evolutionary solutions to problems of locomotion. 15. The evolution of the human brain. 15. Conservation of gene frequencies and Hardy-Weinberg equilibrium. 16. The treatment of adaptive landscapes showing adaptive heights of different possible genotypes.

"Evolution" covers all of the possible topics with completion and accuracy. The work is made accessible to any reader through wide use of graphics to illustrate key concepts.The book is divided into four parts, each dealing with a different facet of evolutionary science: "The Organic Framework" concerns with the evolution of each of the five kingdoms of organisms; "The Psysical and Chemical Framework" focuses on the cellular level, dealing with the common chemical background and mechanisms of living creatures; "The Historical Framework" discusses the events leading up to Darwin's concept of evolution and further into our time; and, finally, "The Mechanisms", which reveals the workings of evolution on small-scale levels, such as gene frequencies and populations. Each of the book's chapters is further supported by an accompinying web site.

This is the most complete book I've ever seen when it comes to the subject of evolution. The author writes with incredible detail and a mastery not often found when it comes to evolutionary biology.
