List of domesticated animals

This page gives a list of domesticated animals,^[1] also including a list of animals which are or may be currently undergoing the process of domestication and animals that have an extensive relationship with humans beyond simple predation. This includes species which are semi-domesticated, undomesticated but captive-bred on a commercial scale, or commonly wild-caught, at least occasionally captive-bred, and tameable. In order to be considered fully domesticated, most species have undergone significant genetic, behavioural and morphological changes from their wild ancestors, while others have changed very little from their wild ancestors despite hundreds or thousands of years of potential selective breeding. A number of factors determine how quickly any changes may occur in a species, but there is not always a desire to improve a species from its wild form. 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:

1. Pets (dogs, cats, ferrets, hamsters, etc.)
2. Livestock (cattle, sheep, pigs, goats, etc.)
3. Beasts of burden (horses, camels, donkeys, etc.)^[2]
