Domestication is a gradual process, so there is no precise moment in the history of a given species when it can be considered to have become fully domesticated. Zooarchaeology has identified three classes of animal domesticates: Pets (dogs, cats, ferrets, hamsters, etc.) Livestock (cattle, sheep, pigs, goats, etc.)

The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes.
Because the evolution of domestic animals is ongoing, the process of domestication has a beginning but not an end. Various criteria have been established to provide a definition of domestic animals, but all decisions about exactly when an animal can be labelled "domesticated" in the zoological sense are arbitrary, although potentially useful.

The physical traits used to distinguish chicken breeds are size, plumage color, comb type, skin color, number of toes, amount of feathering, egg color, and place of origin. [1] They are also roughly divided by primary use, whether for eggs, meat, or ornamental purposes, and with some considered to be dual-purpose. [1]
