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 transplantation of animal organs into humans — known as xenotransplantation — has a long history. Scientists have been trying to transplant animal organs into humans for nearly two centuries.

The theory of animal-to-human transplants, known as xenotransplantation, dates back hundreds of years. Only recently, though, has that goal appeared to be within reach. Only recently, though, has ...
The most recent, but most irrefutable evidence of domestication comes from sites where horse remains were interred with chariots in graves of the Indo-European Sintashta and Petrovka cultures c. 2100 BCE. [159] A 2021 genetic study suggested that most modern domestic horses descend from the lower Volga-Don region.
