Artificial selection, also called selective breeding, is a form of human intervention in plant or animal evolution.
Selective breeding or Artifical Selection is a theory by Charles Darwin that he included in his first book "Origin Of Species" its the opposite of the Natural Selection which states that the strongest specie will survive. The artificial selection or Selective Breeding states the human and scientific interaction to produce a new specie by modifying genetics and DNA.

Artificial selection or selective breeding.
Selective breeding is where you breed animals or plants in such a way as to increase the desirable traits, or characteristics. By specifically selecting breeding partners with high levels of these desirable traits, the likelihood of the offspring having these traits increases. Over several generations, these desirable traits become more and more profound. For example, if farmers take only the best sheep for breeding, then they can be more assured that future generations of sheep will have the same or even improved characteristics. Selective breeding also works in a similar way when developing new crops, or the breeding of dogs for example. Its all about human intervention, where the breeding partners are chosen (or selected) by people.
-Humans have used selective breeding for ages. Horses were originally too small to carry a human alone for any considerable distance, hence the invention of chariots, but selective breeding allowed horses to evolve to sizes that could easily carry even the heaviest passengers. Cattle were bred to produce more milk, and produce more meat. Dogs were bred to fill a variety of jobs, from farming, to hunting, to fighting.

To the extent that domestic means to do with the human household, the answer must be yes. Domestic birds were created by selective breeding.
