Many scientists consider that orphaned wolf cubs were adopted by humans, who took care of them together with their human babies, and thus appeared a new type of wolf-like domesticated animals which, in time, will turn into dogs. According to Dr. Raymond Coppinger of Hampshire College (Massachusetts), those types of wolves that were more interactive towards humans passed these traits to their following generation, and thus creating a kind of wolf that could be more easily domesticated by humans.

Coppinger speaks of a special behavior trait that was essential for the wolf's transformation into dog, and this trait was called "flight distance". It referred to the distance kept by an animal towards a human before running away from what they perceived as danger. In this respect, animals that live at a shorter distance from humans are likely to linger and feed even when these humans are present. Dr. Coppinger says that his argument is that tame or domesticated means being able to eat even in the presence of otherwise perceived as threatening humans. This is precisely what wild wolves cannot do. The side effects of domesticity-purposed selection were the selection of related physical features that were actually genetically caused, plus behavior such as barking.
