๐๐-๐๐๐๐๐ ไฝ Posted May 5 Share Posted May 5 A cat (Felis catus), commonly referred to as the domestic cat or house cat, is a small domesticated carnivorous mammal. It is the only domesticated species of the family Felidae. Recent advances in archaeology and genetics have shown that the domestication of the cat occurred in the Near East around 7500 BC. It is commonly kept as a house pet and farm cat, but also ranges freely as a feral cat avoiding human contact. It is valued by humans for companionship and its ability to kill vermin. Its retractable claws are adapted to killing small prey like mice and rats. It has a strong, flexible body, quick reflexes, sharp teeth, and its night vision and sense of smell are well developed. It is a social species, but a solitary hunter and a crepuscular predator. Cat communication includes vocalizations like meowing, purring, trilling, hissing, growling, and grunting as well as cat body language. It can hear sounds too faint or too high in frequency for human ears, such as those made by small mammals. It also secretes and perceives pheromones. Female domestic cats can have kittens from spring to late autumn in temperate zones and throughout the year in equatorial regions, with litter sizes often ranging from two to five kittens. Domestic cats are bred and shown at events as registered pedigreed cats, a hobby known as cat fancy. Animal po[CENSORED]tion control of cats may be achieved by spaying and neutering, but their proliferation and the abandonment of pets has resulted in large numbers of feral cats worldwide, contributing to the extinction of bird, mammal and reptile species. As of 2017, the domestic cat was the second most po[CENSORED]r pet in the United States, with 95.6 million cats owned and around 42 million households owning at least one cat. In the United Kingdom, 26% of adults have a cat, with an estimated po[CENSORED]tion of 10.9 million pet cats as of 2020. As of 2021, there were an estimated 220 million owned and 480 million stray cats in the world. Etymology and naming The origin of the English word cat, Old English catt, is thought to be the Late Latin word cattus, which was first used at the beginning of the 6th century.[4] The Late Latin word may be derived from an unidentified African language.[5] The Nubian word kaddรฎska 'wildcat' and Nobiin kadฤซs are possible sources or cognates.[6] The forms might also have derived from an ancient Germanic word that was absorbed into Latin and then into Greek, Syriac, and Arabic.[7] The word may be derived from Germanic and Northern European languages, and ultimately be borrowed from Uralic, cf. Northern Sรกmi gรกฤfi, 'female stoat', and Hungarian hรถlgy, 'lady, female stoat'; from Proto-Uralic *kรคฤwรค, 'female (of a furred animal)'.[8] The English puss, extended as pussy and pussycat, is attested from the 16th century and may have been introduced from Dutch poes or from Low German puuskatte, related to Swedish kattepus, or Norwegian pus, pusekatt. Similar forms exist in Lithuanian puiลพฤ and Irish puisรญn or puiscรญn. The etymology of this word is unknown, but it may have arisen from a sound used to attract a cat.[9][10] A male cat is called a tom or tomcat[11] (or a gib,[12] if neutered). A female is called a queen[13][14] (or sometimes a molly,[15] if spayed). A juvenile cat is referred to as a kitten. In Early Modern English, the word kitten was interchangeable with the now-obsolete word catling.[16] A group of cats can be referred to as a clowder or a glaring.[17] Taxonomy The scientific name Felis catus was proposed by Carl Linnaeus in 1758 for a domestic cat.[1][2] Felis catus domesticus was proposed by Johann Christian Polycarp Erxleben in 1777.[3] Felis daemon proposed by Konstantin Satunin in 1904 was a black cat from the Transcaucasus, later identified as a domestic cat.[18][19] In 2003, the International Commission on Zoological Nomenclature ruled that the domestic cat is a distinct species, namely Felis catus.[20][21] In 2007, the modern domesticated subspecies F. silvestris catus sampled worldwide was considered to have likely descended from the Near Eastern wildcat (F. lybica), following results of phylogenetic research.[22][23][a] In 2017, the IUCN Cat Classification Taskforce followed the recommendation of the ICZN in regarding the domestic cat as a distinct species, Felis catus.[24] Evolution Main article: Cat evolution Skulls of a wildcat (top left), a housecat (top right), and a hybrid between the two. (bottom center) The domestic cat is a member of the Felidae, a family that had a common ancestor about 10 to 15 million years ago.[25] The evolutionary radiation of the Felidae began in Asia during the Miocene around 8.38 to 14.45 million years ago.[26] Analysis of mitochondrial DNA of all Felidae species indicates a radiation at 6.46 to 16.76 million years ago.[27] The genus Felis genetically diverged from other Felidae around 6 to 7 million years ago.[26] Results of phylogenetic research shows that the wild members of this genus evolved through sympatric or parapatric speciation, whereas the domestic cat evolved through artificial selection.[28] The domestic cat and its closest wild ancestor are diploid and both possess 38 chromosomes[29] and roughly 20,000 genes.[30] Phylogenetic relationships of the domestic cat as derived through analysis of nuclear DNA:[26][27] Felidae Pantherinae Felinae other Felinae lineages Felis Jungle cat (F. chaus) Black-footed cat (F. nigripes) Sand cat (F. margarita) Chinese mountain cat (F. bieti) African wildcat (F. lybica) European wildcat (F. silvestris) Domestic cat mitochondrial DNA:[31] Felis Sand cat (F. margarita) Chinese mountain cat (F. bieti) European wildcat (F. silvestris) African wildcat Southern African wildcat (F. l. cafra) Asiatic wildcat (F. l. ornata) Near Eastern wildcat Domestic cat Domestication See also: Domestication of the cat and Cats in ancient Egypt A cat eating a fish under a chair, a mural in an Egyptian tomb dating to the 15th century BC It was long thought that the domestication of the cat began in ancient Egypt, where cats were venerated from around 3100 BC,[32][33] However, the earliest known indication for the taming of an African wildcat was excavated close by a human Neolithic grave in Shillourokambos, southern Cyprus, dating to about 7500โ7200 BC. Since there is no evidence of native mammalian fauna on Cyprus, the inhabitants of this Neolithic village most likely brought the cat and other wild mammals to the island from the Middle Eastern mainland.[34] Scientists therefore assume that African wildcats were attracted to early human settlements in the Fertile Crescent by rodents, in particular the house mouse (Mus musculus), and were tamed by Neolithic farmers. This mutual relationship between early farmers and tamed cats lasted thousands of years. As agricultural practices spread, so did tame and domesticated cats .[31][35] Wildcats of Egypt contributed to the maternal gene pool of the domestic cat at a later time.[36] The earliest known evidence for the occurrence of the domestic cat in Greece dates to around 1200 BC. Greek, Phoenician, Carthaginian and Etruscan traders introduced domestic cats to southern Europe.[37] During the Roman Empire they were introduced to Corsica and Sardinia before the beginning of the 1st millennium.[38] By the 5th century BC, they were familiar animals around settlements in Magna Graecia and Etruria.[39] By the end of the Western Roman Empire in the 5th century, the Egyptian domestic cat lineage had arrived in a Baltic Sea port in northern Germany.[36] The leopard cat (Prionailurus bengalensis) was tamed independently in China around 5500 BC. This line of partially domesticated cats leaves no trace in the domestic cat po[CENSORED]tions of today.[40] During domestication, cats have undergone only minor changes in anatomy and behavior, and they are still capable of surviving in the wild. Several natural behaviors and characteristics of wildcats may have pre-adapted them for domestication as pets. These traits include their small size, social nature, obvious body language, love of play, and high intelligence. Since they practice rigorous grooming habits and have an instinctual drive to bury and hide their urine and feces, they are generally much less messy than other domesticated animals. Captive Leopardus cats may also display affectionate behavior toward humans but were not domesticated.[41] House cats often mate with feral cats.[42] Hybridisation between domestic and other Felinae species is also possible, producing hybrids such as the Kellas cat in Scotland.[43][44] Development of cat breeds started in the mid 19th century.[45] An analysis of the domestic cat genome revealed that the ancestral wildcat genome was significantly altered in the process of domestication, as specific mutations were selected to develop cat breeds.[46] Most breeds are founded on random-bred domestic cats. Genetic diversity of these breeds varies b etween regions, and is lowest in purebred po[CENSORED]tions, which show more than 20 deleterious genetic disorders.[47] https://en.wikipedia.org/wiki/Cat Link to comment Share on other sites More sharing options...
