The author tells a good story and ties together his main themes fairly well. He is a philosopher and approaches the subject from that perspective. It's a fun read and easy to follow, but it's definitely not full of scientific facts. The author preferred Noam Chomskey and Stephen Gould's ideas on the early development of man as opposed to Dawkins and Pinker. I definitely am in the Dawkins/ Pinker camp, but that didn't mar the listening experience and I'm always glad to hear a different perspective, and the author presented each camp fairly.
I'm really glad for the existence of audible. I would have never been able to force myself to read this book, but I had a very pleasant experience while listening to it. Thank you audible for making books like this available to me at such a cheap price of only one credit.
The author reads his own book and as with many non-professional readers he reads too slowly. I suggest you listen to it at 1.25 speed.
