Domestic animals were important for the cultural development of Man. The questions regarding the origin of domesticated animals from their wild ancestors can be considered solved. However, questions regarding the process of domestication remain to be answered. This subject is studied by archaeozoology. In this respect the chronology has an important part to play; the first consequence of domestication is the change in size; the early domestication of animals leads to the reduction in size of the body, but certain organs remain uncorrelated. This is applicable for example to the teeth, their reduction in size being smaller than that of jaws. It is further observed that at the beginning of domestication the domestic animals provided less meat than their wild contemporaries. -- AATA
