Breeding Back
Breeding back is a form of artificial selection by the deliberate selective breeding of 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.

Feral
A feral () animal or plant is one that lives in the wild but is descended from domesticated individuals. As with an introduced species, the introduction of feral animals or plants to non-native regions may disrupt ecosystems and has, in some cases, contributed to extinction of indigenous species. The removal of feral species is a major focus of island restoration. Animals A feral animal is one that has escaped from a domestic or captive status and is living more or less as a wild animal, or one that is descended from such animals. Other definitions include animals that have changed from being domesticated to being wild, natural, or untamed. Some common examples of animals with feral populations are horses, dogs, goats, cats, rabbits, camels, and pigs. Zoologists generally exclude from the feral category animals that were genuinely wild before they escaped from captivity: neither lions escaped from a zoo nor the white-tailed eagles re-introduced to the UK are regarded as fera ...

Konik
The Konik or Polish Konik, pl, konik polski, is a Polish List of horse breeds, breed of pony. There are semi-feral populations in some regions. They are usually dun gene, mouse dun or primitive markings, striped dun in color. The Bilgoray, pl, konik biłgorajski, of south-eastern Poland is a sub-type of the breed influenced by Arab horse, Arab and Thoroughbred blood; it is close to extinction. The extinct Sweyki or Schweike sub-type of East Prussia contributed to the development of the Trakehner. The word "konik" means 'small horse'. It may be used in a wider sense to describe the Polish Konik and other similar breeds, among them the Hutsul (horse), Hutsul of the Carpathian Mountains, the Polesian (horse), Polesian of Belarus and the Žemaitukas of Lithuania. Etymology The Polish word ''konik'' (plural ''koniki'') is the diminutive of ''koń'', the Polish word for "horse" (sometimes confused with ''kuc, kucyk'' meaning "pony"). It means 'small horse'.

Taurus Project
The Taurus Project of the German aims to re-create the extinct aurochs, the wild ancestor of domestic cattle, by cross-breeding Heck cattle (themselves bred in the 1920s and 1930s in an attempt to replicate the aurochs) with aurochs-like cattle, mostly from Southern Europe. Herds of these cross-bred ''Taurus cattle'' have been established in Germany, Denmark, Hungary and Latvia, and are used in conservation of natural landscapes and biodiversity.Marcel Keiffenheim (text), Lin Lambert (pictures)"Das Ur-Viech."

Chianina
The Chianina () is an Italian breed of large white cattle. It was formerly principally a draught breed; it is now raised mainly for beef. It is the largest and one of the oldest cattle breeds in the world. The ''bistecca alla fiorentina'' is produced from its meat. History The Chianina is one of the oldest breeds of cattle. It originates in the area of the Valdichiana, from which it takes its name, and the middle Tiber valley. Chianina cattle have been raised in the Italian regions of Tuscany, Umbria and Lazio for at least 2200 years. Columella, writing about types of oxen in about 55 AD, says "''Umbria vastos et albos'' ..." (VI.I.2), which in the first English translation is "''Umbria'' has such as are huge, and of a white colour". Chianina oxen were the principal source of agricultural power in the area until displaced by mechanisation and the collapse of the ''mezzadria'' system following the Second World War; they were in use in agriculture until at least 1970 and are ...

Sayaguesa Cattle
The Sayaguesa is an endangered Spanish breed of domestic cattle. It is named for the comarca of Sayago in the province of Zamora, in the western part of the autonomous community of Castile and León, and is raised almost exclusively in that area. It may also be known as the Zamorana, the Moles de Sayago or the Castellana variedad Sayaguesa. It was traditionally kept mainly for draught work, but is now raised principally for meat. History The Sayaguesa was traditionally kept mainly for draught work; with the mechanisation of agriculture following the Second World War, this use declined. In the 1960s there were successive attempts to improve productive qualities by cross-breeding with Friesian, Braunvieh and Charolais, and later with other breeds. From 1970 the Sayaguesa was included with other regional breeds under the denomination Morenas del Noroeste. In 1997 it achieved separate recognition among the breeds identified by the Ministerio de Agricultura, Alimentación ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutz Heck
Ludwig Georg Heinrich Heck, called Lutz Heck (23 April 1892 in Berlin, German Empire – 6 April 1983 in Wiesbaden, West Germany) was a German zoologist, animal researcher, animal book author and director of the Berlin Zoological Garden where he succeeded his father in 1932. A member of the Nazi party from 1937, he was a close hunting friend of Hermann Göring, and worked under him. One of his projects was the reconstruction of extinct animals such as the aurochs through cross-breeding of various modern breeds which he thought had parts of the original genetic heritage. Heck cattle and Heck horses are named for the resulting animal breeds. Life and work Lutz was the third child of Margarete and Ludwig Heck (1860-1951), director of Berlin Zoo from 1888 to 1931. He grew up with his brother in the grounds of the Berlin zoo and became very interested in animals and zoology from an early age. He was also influenced by German colonial explorer friends of his father and their tales ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinz Heck
Heinz Heck (22 January 1894 – 5 March 1982) was a German biologist and director of Hellabrunn Zoo (''Tierpark Hellabrunn'') in Munich. He was born in Berlin and died in Munich. With his brother, Lutz Heck, who was director of the Berlin Zoological Garden, he worked on two breeding back projects to recreate extinct species. The Heck horse aimed to recreate the tarpan, and the Heck cattle, aimed to recreate the aurochs, the wild cattle of the European forest. This work has been criticised on grounds that once an animal is extinct, it cannot re-exist. This was contrary to Heck's view, which is that while genes of an extinct animal still exist in extant descendants, the animal could still be recreated. Under Nazi Germany, Heinz Heck was among the first political prisoners to be interned—and later released—in Dachau for suspected membership in the Communist Party and for his brief marriage to a Jewish woman. Heck also played an important part in saving the European biso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
