摘要

The words "domestication" and "domestic animal" sometimes lose to-day their classical meaning. People even forget that they had a precise signification in zoology. The author tries to summarize the classical zoological conception of domestication, with some risks of over-simplification. It is difficult to define what is a domesticated animal, but three characteristics can be recognized: some degree of taming, a control of breeding by man, a use of the animal. A useless animal cannot be, or does not remain, domesticated. The difference between a wild species and its derived domesticated form is not always clear and some scientists refuse to separate them. The number of species which are recognized as domesticated by everybody is reduced to about 30. It seems that the ability of an animal to have social relationships with man is an important factor to consider : this explains why molluscs, insects and fishes have no representatives on the agreed list. Nevertheless, a wild species can also be bred and reared by man. There does exist a predisposition to domestication, which depends at least on social organisation, breeding practices, feeding habits and the influence of captivity on fertility. Man cannot hope to domesticate any species he chooses. The domestication process, which gradually leads a species from wild to domestic status is situated in time, with a very variable period according to species. Some new ones can be concerned to-day. Zoologists have not attempted to estimate how long a period of breeding is necessary before becoming domesticated, but it is admitted that it is long. A few breeding generations alone are not enough. Domestication also has a geographic component, with a strong modern tendency to multicentrism. Domestication is the result of a long breeding process, whose consequences on the morphology, anatomy, physiology, behaviour and genetic structure of animals are considerable. Even under the hypothesis that any domestic species could revert to the wild state, a very long period of natural selection would be necessary before the species would again be recognized as wild. The classical zoological conception of domestication is often considered too strict, which is probably true. Nevertheless, it has its logic and consistency. For these reasons, it should not be forgotten.
