Chauvet CaveThe Chauvet-Pont-d'Arc Cave (Grotte Chauvet-Pont d'Arc, ɡʁɔt ʃovɛ pɔ̃ daʁk) in the Ardèche department of southeastern France is a cave that contains some of the best-preserved figurative cave paintings in the world, as well as other evidence of Upper Paleolithic life. It is located near the commune of Vallon-Pont-d'Arc on a limestone cliff above the former bed of the river Ardèche, in the Gorges de l'Ardèche. Discovered on December 18, 1994, it is considered one of the most significant prehistoric art sites and the UN’s cultural agency UNESCO granted it World Heritage status on June 22, 2014.
MagdalenianThe Magdalenian cultures (also Madelenian; French: Magdalénien) are later cultures of the Upper Paleolithic and Mesolithic in western Europe. They date from around 17,000 to 12,000 years ago. It is named after the type site of La Madeleine, a rock shelter located in the Vézère valley, commune of Tursac, in France's Dordogne department. Édouard Lartet and Henry Christy originally termed the period L'âge du renne (the Age of the Reindeer). They conducted the first systematic excavations of the type site, publishing in 1875.
OxAn ox 'ɒks (: oxen, 'ɒksən), also known as a bullock (in BrE, AusE, and IndE), is a bovine, trained and used as a draft animal. Oxen are commonly castrated adult male cattle; castration inhibits testosterone and aggression, which makes the males docile and safer to work with. Cows (adult females) or bulls (intact males) may also be used in some areas. Oxen are used for plowing, for transport (pulling carts, hauling wagons and even riding), for threshing grain by trampling, and for powering machines that grind grain or supply irrigation among other purposes.
Heck cattleThe Heck or Munich-Berlin is a German breed or type of domestic cattle. It was bred in the 1920s by Heinz and Lutz Heck in an attempt to breed back the extinct aurochs (Bos primigenius). 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.
AtavismIn biology, an atavism is a modification of a biological structure whereby an ancestral genetic trait reappears after having been lost through evolutionary change in previous generations. Atavisms can occur in several ways, one of which is when genes for previously existing phenotypic features are preserved in DNA, and these become expressed through a mutation that either knocks out the dominant genes for the new traits or makes the old traits dominate the new one.
Domestication of animalsThe domestication of animals is the mutual relationship between non-human animals and the humans who have influence on their care and reproduction. Charles Darwin recognized a small number of traits that made domesticated species different from their wild ancestors. He was also the first to recognize the difference between conscious selective breeding (i.e. artificial selection) in which humans directly select for desirable traits, and unconscious selection where traits evolve as a by-product of natural selection or from selection on other traits.
