Bred-back breeds are interesting for conservation biology since they may fill an ecological gap that has been left due to the extinction of the wildtypes, in some cases due to hunting by humans. As long as food choice, behaviour, robustness, defence against predators, hunting or foraging instincts and phenotype are the same as in the wild type, it will function like it in the wilderness. Releasing such animals into the wild would fill the previously empty niche and allows a natural dynamic between the species of the ecosystem to re-evolve. However, breeding back-attempts do not always result in an animal that is closer to the wild type than other domestic breeds. For example, heck cattle bear less resemblance to the aurochs than many Iberian fighting cattle do.

Famous quotes containing the word use:
“... it is use, and use alone, which leads one of us, tolerably trained to recognize any criterion of grace or any sense of the fitness of things, to tolerate ... the styles of dress to which we are more or less conforming every day of our lives. Fifty years hence they will seem to us as uncultivated as the nose-rings of the Hottentot seem today.”
—Elizabeth Stuart Phelps (1844–1911)
