That the dog evolved from the wolf is an accepted fact of evolution, but the question of how wolf became dog has remained a mystery, obscured by myth and legend. How the Dog Became the Dog presents the 'domestication' of the dog as a biological and cultural process that began with cooperation and has taken a number of radical turns since. At the end of the last Ice Age, the first dogs emerged with their humans from refuge against the cold. In the eighteenth century, humans began the drive to exercise full control of dog reproduction, life and death, to complete the domestication of the wolf that began so long ago.
