I absolutely love this book. I bought the audio book version and it is just the kind of info / evolution story that I was looking for. I can't even say I agree with every assessment of his or that his conclusions are accurate even though I do agree with most, but just the overall take and the story of humans and what makes us was fantastic. He had a lot of new theories I hadn't considered and made a lot of connections that made me go WOW. This book is great. Loved it.
