Generally, the domestic dog is the oldest domestic animal, because it is supposed to be domesticated by a person ten to 15 thousand years back. The first remains of a domestic dog were discovered in Mesolithic sites in various places. It appears that the initial European breed was quite little and would, in general, be best in comparison to today’s man. There is almost no animal species on the planet, within which there will be obvious variations in the exterior and the dogs. Some individuals associate diversity with different ancestors. Many old authors, based on the diversity of today’s dog breeds, think that your dog was created by crossing several related species from the dog family. Included in this were also the beginner of the idea of evolution Charles Darwin and the Austrian ethologist Konrad Lorenz, who figured the ancestor of the domestic canine was a wolf and a jackal. Another, even more probable and, more recently, a more and much more supported theory scientifically, 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 due to intensive, pretty much planned breeding and selection, and sudden, also unpredictable heritable genetic changes – mutations. The full total result is the emergence of several different breeds of dogs, whose specimens differ in proportions, torso and head, color, length and quality of the hair, and lastly also in usefulness for numerous purposes.
