Domestication of Animals

Biological Process

Like genetic selection in that the parent animal becomes isolated from the wild population → leads to genetic drift

Cultural Process

How animals are integrated into human societies.

Symbiosis

All conditions of permanent living-together of two different species.

Dmitry Belyaev

Proposed a hypothesis that the primary factor selected during domestication was a behavioral trait which is called “tamability”.
