Generally, the domestic dog may be the oldest domestic animal, since it is meant to be domesticated by way of a person ten to 15 thousand years back. The first continues to be of a domestic puppy were found out in Mesolithic sites in different places. It seems 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 variations in the exterior and the dogs. Some social people associate diversity with different ancestors. Many old authors, based on the diversity of today’s pet breeds, think that the dog was shaped by crossing many related species from your dog family. Included in this were also the newbie of the theory of evolution Charles Darwin and the Austrian ethologist Konrad Lorenz, who concluded that the ancestor of the domestic doggy has been a wolf and a jackal. Another, even more probable and, more recently, a scientifically increasingly more supported theory, speaks of the normal ancestor of a wolf and a domestic doggie. In accordance with this concept, the current diversity of canines is supposed to be due to intensive, more or less planned choice and breeding, and sudden, also unpredictable heritable genetic adjustments – mutations. The result is the emergence of many different varieties of dogs, whose specimens differ in size, torso and head, color, high quality and amount of the hair, and lastly also in usefulness for different purposes.
