That the dog evolved from the wolf is an accepted fact of evolution and history, but the question of how wolf became dog has remained a mystery, obscured by myth and legend. posits that dog was an evolutionary inevitability in the nature of the wolf and its human soul mate. The natural temperament and social structure of humans and wolves are so similar that as soon as they met on the trail they recognized themselves in each other.

adeptly and engrossingly examines this singular relationship. Combining the most recent scientific research with Mark Derr's original insights, this book shows that dogs made us human just as humans affected the evolution of dogs.
