The symbiosis the interdependent relationship between two different species of organisms, in which each benefits from the relationship between humans and tamed wolves produced the domesticated dog. This first animal domestication is an excellent example of the domestication process. Humans were in contact with wolves early in the evolution of both species. Early humans and small wolves co-occurred between 500, 000 and 300,000 years ago in sites in northern China. A cave excavated in southern France contains human-built shelters 125,000 years old, with a wolf skull apparently intentionally placed at each entrance. Humans have had a long history of knowing the wolf as a wild animal and ample time to experiment with the species as a tamed animal.

【】 Tamed animals are defined as being dependent on people and willing to stay with or close to them. 【】 Domesticated animals are1 raised in captivity, and humans control their breeding, territorial organization, and food 1supply. 【】 The domesticated dog is generally thought to have derived from tamed wolves.【】 Initially, wolf pups were tamed and brought into close association with humans.

Remains of tamed wolves look like those o1 wild wolves. Thus, the evidence for taming is difficult to determine in most cases. According to one researcher, fossil bone characteristics cannot provide evidence for distinguishing tamed wolves from early domestic dogs, and it is in fact still doubtful how clear the distinctions are between ,wild and tamed wolves. However, it is possible to distinguish wild wolves from full) domesticated dogs.

Domestication is more a process than an vent, but dogs are quite different creatures when compared to wolves; even dogs such as Siberian huskies that superficially resemble wolves. The morphological changes in wolves as they became dogs initially involved foreshortening of the muzzle or nose, crowding of the tooth rows, and a proportional reduction in size of the teeth. One of the earliest examples o foreshortening in wolf skulls was found in conjunction with a Paleolithic mammoth hunters' campsite in the Ukraine dating to about 31,000 years ago.

Over antiquity, humans tamed a diverse1 array of other animals, including hyenas,gazelles, and the foxes tamed by the ancient Egyptians. These and other carnivores such as the cape hunting dog, the coyote, the jackal, and the large cats have been tamed,but never domesticated.

The successful domestication of the dog from the wolf springs from the exceptional fit between humans and wolves with respect to food, behavior, and habitat. Between 10,000 and 20,000 years ago, both humans and wolves in small bands hunted many of the same animals. Both deployed vigorous adults to hunt their prey. Both coordinated their efforts to produce more hunting success.Both were able to drive, weaken, and kill prey that was larger than they were by working in relays to chase, and control the fight of the prey. Captures were carried back to young individuals and nursing females. Both species coordinated their hunting efforts (and their social organization) by a combination of vocal and visual communication. Wolves and humans were organized into a hierarchy of dominant and subordinate individuals.


In short the interactions, organization, mode of communication, and society of small human settlement would not have been totally alien to the wolf.

The domestication of tamed wolves did not have to overcome us much of the intrinsic nature of the animal as the domestication of some other animal might have. Several conditions are necessary for an animal to be domesticated. First, the young animal has to be physically tough enough to survive the trauma of removal from its own mother (probably while still feeding from its mother). Further, it must be hardy enough to adapt to a new diet and environment. Second, the species' behavior must be compatible with humans’ social structure. What is needed is a social animal with dominance hierarchies that will accept humans as leaders and that will identify with humans for life. Wolves conform well to these conditions, whereas most other animals do not.
