Generally, the domestic dog may be the oldest domestic animal, because it is supposed to be domesticated by way of a person ten to 15 thousand years back. The first remains of a domestic doggy were discovered 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 animal species on the planet, within which there will be obvious variations in the exterior and the canines. Some people associate diversity with various ancestors. Many old authors, on the basis of the diversity of today’s doggy breeds, believe that the dog was shaped by crossing various associated species from the dog family. Among them were also the beginner of the idea of evolution Charles Darwin and the Austrian ethologist Konrad Lorenz, who figured the ancestor of the domestic dog had been a wolf and a jackal. Another, even more probable and, recently, a more and much more supported theory scientifically, speaks of the common ancestor of a wolf and a domestic dog. According to this theory, the existing diversity of dogs is supposed to be due to intensive, more or less planned breeding and selection, and sudden, unpredictable heritable genetic changes – mutations even. The total result may be the emergence of several different varieties of dogs, whose specimens differ in size, torso and head, color, length and high quality of the hair, and lastly furthermore in usefulness for various purposes.
