Wild ancestor
From Wikipedia, the free encyclopedia
Wild ancestors are the original species from which domesticated plants and animals are derived. Examples include dogs which are derived from wolves and flax which is derived from Linum bienne. In most cases the wild ancestor species still exists, but some domesticated species, such as camels, have no surviving wild relatives. In many cases there is considerable debate in the scientific community about the identity of the wild ancestor or ancestors, as the process of domestication involves natural selection, artificial selection, and hybridization.
Wild ancestors have gone through genetic changes to achieve biological mutualism with humans. This is due to humans selectively breeding those species.
