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.)
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 domestication of animals and plants was triggered by the climatic and environmental changes that occurred after the peak of the Last Glacial Maximum and which continue to this present day. These changes made obtaining food by hunting and gathering difficult. [12] The first animal to be domesticated was the dog at least 15,000 years ago. [1]
Among extant land animals in North America, the bison is the heaviest and the longest, and the second tallest after the moose. Once roaming in vast herds , the species nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle.
