In general, the domestic dog is the oldest domestic animal, since it is meant to be domesticated by a person ten to fifteen thousand years back. The first continues to be of a domestic pet were uncovered in Mesolithic sites in different places. It appears that the earliest European breed was quite little and would, in general, be best in comparison to today’s guy. There is almost no pet species in the worldwide world, within which there would be obvious differences in the exterior and the canines. Some social people associate diversity with various ancestors. Many older authors, based on the diversity of today’s puppy breeds, think that the dog was produced by crossing several associated species from the dog family. Included in this were also the beginner of the theory of evolution Charles Darwin and the Austrian ethologist Konrad Lorenz, who concluded that the ancestor of the domestic pet has been a wolf and a jackal. Another, even more probable and, recently, a scientifically increasingly more supported theory, speaks of the normal ancestor of a wolf and a domestic doggy. According to this concept, the existing diversity of dogs is meant to be because of intensive, more or less planned selection and breeding, and sudden, unpredictable heritable genetic changes – mutations even. The result may be the emergence of many different varieties of dogs, whose specimens differ in proportions, head and torso, color, high quality and amount of the hair, and lastly furthermore in usefulness for various purposes.
