Sixty-five million years ago, a world that belonged to the dinosaurs suffered a cosmic catastrophe, obliterating the kingdom of Tyrannosaurus rex. For the sixty-five million years folllowing, the bones of the last king of the dinosaurs lay hidden. Then, at the turn of the 20th Century, scientists began to coax the first fragments from the badlands of western North America. They found a super-carnivore that stood eighteen feet tall and was forty feet from head to tail. Today, the bones of Tyrannosaurus rex allow us to encounter the greatest meat-eating machine of the prehistoric world, and T. rex has become the most famous of all the dinosaurs, an ultimate expression of savagery and power.

At times, dogs appear to move and react like wild animals. Yet they are, by definition, domesticated. In perhaps only fourteen thousand years, humans have modified and manipulated a single species to create more than four hundred breeds. But for all their variety of appearance, all dogs are simply mutations of their closest ancestral relative... the wolf. How did the dog come to be so successfully domesticated from its wild ancestors? Dr. Rodney Honeycutt discusses the genetics of domestication and some of the special qualities of the dog, such as its phenomenal senses of hearing, smell, and taste. A survey of strange and wonderful breeds of dogs is presented, from dogs that whistle to dogs that sing, and the vulpines (foxes) which can climb trees. Also, some of the unique jobs of dogs are explored, from sniffing out termites, to herding goats and finding missing persons.
