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.

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.
