Evolution: An Introduction

I bought this book after listening to about half of Mr. Stearns' 36 lectures on evolution which are available free through iTunes U as one of the Open Yale courses. My hope is that some of the illustrations that Mr. Stearns is using in his lectures (which a listener cannot see), will be in the textbook. If you, like me, are not a biologist, you might want to dip your toe in the water by listening to the lectures before tackling the book. I am very impressed with both.
