It is likely that the house cat (Felis silvestris catus) and the ferret (Mustela furo) were domesticated to protect stored grains and other food materials from rodents (Zeuner, 1963). Other species were domesticated as sources of food, clothing, labor, transportation, adornments or sacrificial offerings. In contrast, the domestic value of many wild species has been largely ignored or, if recognized, social and technological barriers have often prevented their domestication. The quagga (Equus quagga), a small, horse-like animal from Central and South Africa, was treated as vermin by the Boer and English farmers and was hunted to extinction despite its docile nature, ©CAB International 2002.
1). This difference in variation was statistically significant and evidently due to the different size of the foundation stocks. One way to preserve genetic diversity in captive populations is to establish a number of subpopulations under the assumption that if drift occurs, the genes fixed or lost will not be the same in the various groups. , 1997), an important consideration when restocking captive-reared animals in nature. Fiumera et al. (2000) report on the loss of genetic diversity in captive-bred populations of a Lake Victoria cichlid (Prognathochromis perrieri) and the importance of captive subpopulations located at a number of institutions in maintaining genetic diversity in the population as a whole.
The usefulness of comparative studies is limited by the perceived representativeness of the animal stocks employed. It is difficult, if not impossible, to find contemporary wild populations that match the wild ancestors of many of our common domesticated species. Biological differences found between wild and domestic stocks will to some degree apply only to the specific populations studied. Hybridization studies can provide useful information on the inheritance of traits important to domestication, but little more.
