The development of the dog breed

Article by Daniel Myles

The family dog ??is within the animal kingdom on the nature of wolves, genus of the real dogs (canines) in the canine family. The family of dogs is the carnivores (meat-eaters, carnivores) subordinate, in turn, belong to the class of mammals (Mammalia) in the trunk of the chordates (Chordata).

It is currently assumed that the common wolf ancestor of all dogs. The researchers argue to this day about the time of the removal of dogs from wolves. Some argue that even before 135 000 years ago there were signs of a separation of wolf and dog. Opponents of this theory point to a lack of evidence in the form of excavation and believe that the dog is much younger.

One thing is certain, with the settling of man adapts to the behavior of dogs in conformation and their living conditions. The man began to select dogs for specific criteria in order to use them for certain tasks. Of planned breeding could not speak yet. Nevertheless, formed out of the assigned reading different anatomical characteristics and personality traits which were the basis for the emergence of dog breeds. Over the generations, this cemented properties.

First it was only common features such as persistence in herding dogs, strength and courage to guard dogs, and agility and varminty for hunting dogs, which distinguished the dogs in a particular region or within a large dog pack. But often had dogs with similar performance characteristics over time and a shared physical characteristics. This was due not only to adapt to the common environmental conditions, but accidental or planned crossing of related animals to each other. When animals are repeatedly mated with the same or at least similar properties together, we can promote in this way manifest desired properties. In the opposite sense from one eradicates undesirable properties in the discipline in which we exclude carriers of the trait and sire of this character for the breed. At the beginning of the scheduled dog breeding was restricted to pure selection (selection). With the discovery of Mendel's laws were the breeders insight into the backgrounds of inheritance, and used this now for their breeding.

Today dogs are bred to race, Beauty and performance assessed. As a criterion exists for each breed a breed standard, which is filed with the F
