Edey and Johanson do a splendid job of detailing the philosophies and scientific discoveries that led to the formation of modern evolutionary thought. The history they present is filled with interesting details and offers a good refresher on high school biology. It begins with many pre-Darwinian thoughts and works its way up to the present (or 1990). Along the way the authors occasionally dialogue between themselves explaining various topics, offering analogies for concepts, presenting possible theories, and giving personal details about the men and women involved in this field.

...the book is more presentational rather than apologetic. On occasion the authors did generalize creationism with Biblical fundamentalism, but they also admit once to the difficulty of originating life. I would also have liked to have seen more fossil discoveries outside the realm of humanity, a discussion on stem cell and embryo development, and perhaps a brief tracing of the likely line of descent from single celled bacteria to the major classes of vertebrates. (I am a theist, so take into consideration any bias.)

Overall, there were only a few tedious pages, but it is otherwise an excellent book that I had a hard time putting down.
