There is a hypothesis according to which wolves got separated into two kinds of populations: the pack of hunters and village-directed kind of scavengers. The following selection steps were not actually defined, but perhaps there was a certain tension between these two groups. From the archeological viewpoint, there isn't certainty about the earliest known domestication until 7,000 BC. According to other evidence, dogs' domestication began in East Asia. There is a certain difficulty in deciphering the bones' structural differences, and because of that the culturally-based domestic dog identification is quite valuable. The first dog found buried together with a human dates back with about 12,000 years ago, in the country of Palestine.

Due to the domestication of wolves, a lot of changes occurred throughout time, changes that all domesticated mammals actually go through. Among these changes we could mention a reduction in the general size, changes in the coat's color and marks; the jaw got shorter, and the teeth got more crow in the beginning, and later on the teeth got shrunk. Another change was the fact that in front of the forehead there was developed a pronounced vertical drop. Wolf-like behavior such as regurgitating partially digested food for their young cubs also got lost in the process of domestication. Before the use of DNA, there were two research schools of thought. Most researchers considered that the early dogs descended from wolves through the process of taming. According to another category of scientists, although they still considered wolves to be the main ancestors of dogs, they also shared the suspicion that coyotes or jackals had also been involved in the domestication process.
