Striking paintings, from an adorable wolf pup to a wide range of modern-day dog breeds, illustrate this insightful story of teamwork and friendship. Through the eyes of a prehistoric boy and a lone wolf pup, we see how the bond between our ancestors and these wild animals may have developed. Starting as enemies competing for food, the wolf and the boy realize that they’ll eat better and be safer if they team up. Over time, others catch on, and as many of the wolves become more domesticated, the humans breed them for skills like hunting, herding, pulling, and rescuing. And today, there are more breeds of dog than of any other animal, all thanks to this relationship that started so long ago.

    Exceptional Coverage. This authoritative volume starts with a clear introduction to the animal world, examining the reasons for the apparently infinite variety of animal forms and major evolutionary developments.

Visually Breathtaking. Spectacular photographic portraits bring a vast array of animals vividly to life, with special features on well-known and important animals such as the Galapagos tortoise.
