The domestic dogs descent from the wolf is an accepted part of evolution, but the question of how the wolf became the dog has remained a mystery, and the subject of myth and legend. How the Dog Became the Dog shows that the dogs domestication was both a biological and cultural process. At the end of the last Ice Age, the first dogs emerged with their human companions from refuge against the cold. It was only in the eighteenth century that humans began to exercise full control of dog reproduction, life and death, to complete the domestication of the wolf, begun so long ago.
