This book is carefully written with all of the proper citations typical of an academic text. I found the author to be straightforward about what he knows and how he knows it. Also, Burroughs is not afraid to let you know when he is speculating as opposed to interpretations based on scientific facts. In the end the book is a great read. I recommend it to anyone interested in the climate that early homo sapiens evolved in.
