The human race's progress on the Earth has been due in part to the animals
that people have been able to utilize throughout history. Such domesticated animals
carry people and their burdens. They pull machinery and help cultivate fields. They
provide food and clothing. As pets they may amuse or console their owners.
Domesticated animals are those that have been bred in captivity for many
generations. While a single animal may be tamed, only a species of animal can be
considered domesticated. In the course of time, by selective breeding, certain
animals have changed greatly in appearance and behaviour from their wild
ancestors. There is a vast difference between the scrawny red jungle fowl of
southern Asia and its descendant, the meaty, egg-laying farm chicken. Not all
domestic animals are tame at all times. An angry bull, a mother goose, or a mother
sow with young piglets can be vicious. Some creatures confined in zoos breed in
captivity. The lion is an example. These animals are not domesticated, however, for
they remain wild and dangerous.
