The domestic dog, also known as Canis lupus familiaris, originated from the domestication of the gray wolf (Canis lupus). The domestication process continues even today, if we take into account the fact that the crossing of dogs with the aim of creating “designer dogs” he continues. There are several theories explaining how the process of domestication took place. Therefore, according to some studies, the wolf pups that are caught at an early age to be raised and tamed by man, are easily trained and socialized.
However, some researchers say that in the case of wolf pups are already a few months, it is very difficult to get any socialization or domestication, and attempts are rarely successful. Many scientists believe that orphaned wolf pups adopted by human beings were tamed quickly and are considered first dogs.
According to Dr. Raymond Coppinger of Hampshire College (Massachusetts), types of wolves that were more interactive with humans passed these traits to the next generation, and it was easier to reach a complete domestication. Coppinger speaks of a particular behavior trait was essential to transform the wolf into a dog, and this feature is called “flight distance”. He referred to the distance maintained by an animal of a man before fleeing what they perceive as danger.
In this sense, the animals that live at a distance less than humans are likely to stay. Dr. Coppinger says the domesticated can eat, even in the presence of humans. This is precisely what the wolves can not do.
