A group of my students and I read this book this semester. During the discussion period for the final chapter, one of the students said, "I cried. This was the best book I have ever read." On the other hand, another student expressed great disappointment with the book. Another student quipped, "There weren't enough examples about pigeons." All in all, this book provides excellent food for thought today, just as it did 140 years ago when it was first published. I found Darwin's insights and synthesis of ideas, based on the accumulation of carefully collected observations combined with intellectual leaps to be inspiring. There are flaws in portions of the book to be sure, but this is a book that all biologists and biology students should have a chance to read and discuss. When you read it, make sure you read the entire book, discuss it with a friend or two as you read, and you can look forward to a perfect conclusion to this paradigm shifting book that continues to influence modern biological thought.
