The most ancient kind of animals is the dog-a tame wolf. The dog’s rights evolution occurred very quickly. There are more than five thousand breeds of domestic dogs, which owe their physical and psychological qualities of a wolf or a random mutation (the results of crossbreeding of dogs with the jackal can’t be taken into account).
There are the common ancestors for the dog and the wolf, but these mammals have gone to two different ways: some were wild and fierce, while others were pets. In spite of this, the basic quality remained unchanged for centuries: both the wolf and the dog wag its tail, expressing pleasure; tail is short, from fear, shows his teeth and growl when angry; mark their territory, they have the same period of gestation; they are subject to the same parasite and diseases.
The breeds of dogs that had already modern look began to appear in Neolithic period. There are many different breeds of dogs, because of the natural mutation, ddaptation to climatic conditions or human-separated crossings. However, modern classification of certain breeds of dogs is based on the ability to one or another kind of activity: hunting, herding, guard, working, fine.
The most credible hypothesis tells that the first distinct breed of dogs was Saluki, Arabian Hound, whose name translates from Arabic as “noble.” The first time the concept of “rock” has been defined precisely by the Arabs, in favor of this interpretation. Initially it was about horses, and then – about dogs.
