Tameness may arise naturally (as in the case, for example, of island tameness) or due to the deliberate, human-directed process of training an animal against its initially wild or natural instincts to avoid or attack humans.
[1] In the English language, "taming" and "domestication" refer to two partially overlapping but distinct concepts.
Similarly, taming is not the same as animal training, although in some contexts these terms may be used interchangeably.
[1][5][6] Human selection included tameness, but domestication is not achieved without a suitable evolutionary response.
[7] Domestic animals do not need to be tame in the behavioral sense, such as the Spanish fighting bull.
