It has been proven that the dog comes from a wolf, which, to a certain extent, determines dog behavior. It is believed by many researchers, the ancestors of dogs and wolves were domesticated about 12 thousand years ago. However, this conclusion did not come immediately. Concerning the origin of the dog for a long time there were different opinions. Professor Bjorn Courtenay, a prominent Scandinavian expert in the field of origin and evolution of mammals believes that if there was no wolf in the genealogical tree of a dog and the other canines, say a jackal or wild dog species, then it definitely would have affected the structure of the canine skull, especially the teeth. But none of that not be found, at least in dogs of the Old World, Kurt believes that the ancestors of dogs may be wolves of Southeast and South Asia.
You may use free sample research papers on dog behavior to understand that the dog initially differed little from the wolf, for thousands of years man has formed an amazing diversity of species. Most dog breeds are so different from the wolf that only by studying the structure of their skeleton and behavior it is possible to establish their origin. The traits particular to the wolf, defining relationships with neighbors and hunting habits, can also be found in dogs. Differences in the nature and physical development of individuals formed the basis for the development of new species.
Thus was born the modern breeds of dogs with their characteristic external features and differences in behavior. This process is regulated by the external environment, especially climate. Small breeds, almost without wool, could not appear in the cold caves of prehistoric man, it does not befit a major dog with long hair to live in the tropics. Now there is a different picture regardless of the climatic conditions when in the owner’s home dogs of various breeds can live.
The man was able to significantly change dog behavior as well as its instincts. Only in very rare cases, there is no this or that ability of the wolf in some dog breeds. So, African fables dog is not able to bark. As for the strongly differing hunting instincts among different dog breeds, they are examples of differences mainly in the behavior and degree of the development. In general, almost any dog sometimes able to demonstrate extremely unusual forms of behavior, which in a similar situation would be most characteristic of the wolf. Although such behaviors in dogs are rare, they still preserved – if only the structure of their body has not changed so much that some action was simply not feasible for them. As a result, multi-selection ability of the dog to commit such acts decreased, which, however, was inadvertently: in the past it was just very difficult to predict what particular properties would be acquired by the animal in the breeding, say, the good shepherd, or a good setter.
But the main characteristics of the wolf are remarkably well preserved, even in dogs of decorative breeds.
This was exactly what made the dog a dog. Wolf was easy to tame just because it is a largely social animal. The cat, loner by nature, anciently lived next to a man, but in spite of this, their relationship almost never been close. A cat refers to the person as to any of its relatives. A dog, in most cases, sees the man as one wolf sees another, usually more powerful, and in this their very material difference from cats.
