Generally, the domestic dog may be the oldest domestic animal, since it is meant to be domesticated by a person ten to fifteen thousand years ago. The first continues to be of a domestic puppy were found out in Mesolithic websites in various places. It appears that the earliest European breed was quite small and would, generally, be best compared to today’s man. There is almost no pet species in the worldwide world, within which there will be obvious variations in the surface and the canines. Some people associate diversity with various ancestors. Many older authors, based on the diversity of today’s doggy breeds, believe that your dog was produced by crossing several associated species from the dog family. Among them 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 doggie has been a wolf and a jackal. Another, more probable and, recently, a scientifically increasingly more supported theory, speaks of the normal ancestor of a wolf and a domestic pet. According to this concept, the existing diversity of canines is meant to be because of intensive, more or less planned breeding and choice, and sudden, unpredictable heritable genetic changes – mutations even. The full total result is the emergence of several different breeds of dogs, whose specimens differ in size, head and torso, color, high quality and amount of the hair, and also in usefulness for various purposes lastly.
