Breeding-back
Breeding back is a form of artificial selection by the deliberate selective breeding of domestication, domestic (but not exclusively) animals, in an attempt to achieve an animal breed with a phenotype that resembles a wild type ancestor, usually one that has gone extinct. Breeding back is not to be confused with dedomestication. It must be kept in mind that a breeding-back breed may be very similar to the extinct wild type in phenotype, ecological niche, and to some extent genetics, but the gene pool of that wild type was different prior to its extinction. Even the superficial authenticity of a bred-back animal depends on the particular stock used to breed the new lineage. As a result of this, some breeds, like Heck cattle, are at best a vague look-alike of the extinct wild type aurochs, according to the literature.Cis van Vuure: Retracing the Aurochs – History, Morphology and Ecology of an extinct wild Ox. 2005.

Heck Cattle
Heck cattle are a hardy breed of domestic cattle. These cattle are the result of an attempt by Heinz and Lutz Heck to breed back the extinct aurochs (''Bos primigenius'') from modern aurochs-derived cattle in the 1920s and 1930s. Controversy revolves around methodology and success of the programme. There are considerable differences between Heck cattle and the aurochs in build, height, and body proportions. Furthermore, there are other cattle breeds which resemble their wild ancestors at least as much as Heck cattle.van Vuure, Cis (2005) ''Retracing the Aurochs - History, Morphology and Ecology of an extinct wild Ox''. History Heck cattle originated in Germany in the 1920s and 1930s in an attempt to breed back domestic cattle to their ancestral form: the aurochs (''Bos primigenius primigenius'').van Vuure, Cis (2005) Retracing the Aurochs - History, Morphology and Ecology of an extinct wild Ox.
