The Wild Horse (Equus ferus or Equus ferus caballus) is a member of the Horse genus which currently is native only in Asia. The true wild horse is not merely a feral horse like the Mustang; a true wild horse species is one which was never successfully domesticated. Feral horse in the Pentland Hills, Scotland. ...

Two species or subspecies (taxonomy is debated) of wild horses survived into modern times: The Tarpan or Eurasian Wild Horse (Equus ferus ferus), once native to Europe and Asia, and the Przewalski's Horse or Mongolian Wild Horse (classification disputed, either Equus ferus przewalskii or Equus przewalskii), native to Central Asia and the Gobi Desert. The Tarpan became extinct in captivity in Ukraine in 1918 or 1919. The Przewalski's Horse is still found today, though it is an endangered species and for a time was considered extinct in the wild. Roughly 1500 animals are protected in zoos around the world, and today, a small breeding population has been reintroduced in Mongolia.^[1] As of 2005, a cooperative venture between the Zoological Society of London and Mongolian Scientists has resulted in a free-ranging population of 248 animals in the wild.^[2] Trinomial name Equus ferus ferus Boddaert, 1785 The Tarpan, Equus ferus ferus, was the Eurasian wild horse. ...

The Przewalski has notable biological differences from the domestic horse; unlike domesticated horses, which have 64 chromosomes, the wild horse has 66 chromosomes. However, the offspring of Przewalski and domestic horses are fertile, possessing 65 chromosomes.^[3] Binomial name Equus caballus Linnaeus, 1758 The horse (Equus caballus, sometimes seen as a subspecies of the Wild Horse, Equus ferus caballus) is a large odd-toed ungulate mammal, one of ten modern species of the genus Equus. ... Domesticated animals, plants, and other organisms are those whose collective behavior, life cycle, or physiology has been altered as a result of their breeding and living conditions being under human control for multiple generations. ...

Other species of wild horses were once indigenous to North America, as well, populating the continent before and during the last Ice Age. Approximately 10,000 years ago, some horses in the Western Hemisphere migrated to Eurasia across the Bering land bridge, and fanned out from Siberia to the rest of Asia, Europe, and the Middle East. What horses remained behind became extinct in North America. There are several competing theories about why this happened. One theory holds that climate changes associated with the end of the last Ice Age caused the extinction of the horse, the mammoth and other large land animals. Another theory holds that newly-arrived humans hunted horses to extinction. A third holds that the newly arrived humans brought a biological factor which caused the demise of horses and other large ungulates in the Americas. It is also possible that it was a combination of factors.^[4] North America North America is a continent[1] in the Earths northern hemisphere and (chiefly) western hemisphere. ...

Taxonomy

While taxonomy is debated, one view is that the wild horse and domestic horse belong to the same species. Thus, to conform to the Code of the International Commission of Zoological Nomenclature the scientific name of the wild horse Equus ferus was discontinued by Wilson and Reeder in 1993 and wild horses were added to Equus caballus, the name given by Linnaeus. Some scientists criticized this change of the scientific name, arguing in favor of a distinction between wild and feral or domesticated animals.^[5] Binomial name Equus caballus Linnaeus, 1758 The horse (Equus caballus, sometimes seen as a subspecies of the Wild Horse, Equus ferus caballus) is a large odd-toed ungulate mammal, one of ten modern species of the genus Equus. ... The International Code of Zoological Nomenclature (ICZN) is a set of rules in zoology that have one fundamental aim: to provide the maximum universality and continuity in classifying all animals according to taxonomic judgment. ... Year 1993 (MCMXCIII) was a common year starting on Friday (link will display full 1993 Gregorian calendar). ... A painting of Carolus Linnaeus Carl Linnaeus, also known after his ennoblement as Carl von Linné, and who wrote under the Latinized name Carolus Linnaeus (May 23, 1707 – January 10, 1778), was a Swedish scientist who laid the foundations for the modern scheme of taxonomy. ...

As a result, in 2003, the International Commission on Zoological Nomenclature "conserved the usage of 17 specific names based on wild species, which are pre-dated by or contemporary with those based on domestic forms", re-confirming Equus ferus for the wild horse. Taxonomists who consider the domestic horse a subspecies of the wild horse should use Equus ferus caballus but the name Equus caballus remains available for the domestic horse where it is considered to be a separate species. ^[6] Year 2003 (MMIII) was a common year starting on Wednesday of the Gregorian calendar. ... Taxonomy (from Greek ταξινομία from the words taxis = order and nomos = law) may refer to either a hierarchical classification of things, or the principles underlying the classification. ...

Feral horses

Horses which live in an untamed state but have ancestors who have been domesticated are not true "wild" horses; they are feral horses. The best known examples of feral horses are the "wild" horses of the American west. When Europeans reintroduced the horse to the Americas, beginning with the arrival of the Conquistadors in the 15th century, some horses escaped and formed feral herds known today as Mustangs. The Australian equivalent to the mustang is the brumby, descendants of the horses let loose in Australia by English settlers. In Spain, the free-ranging feral horse is known as Sorraia. There are also isolated populations of feral horses in a number of places, including Sable Island off the coast of Nova Scotia, and Assateague Island off the coast of Virginia. Some of these horses are said to be the descendants of horses who managed to swim to land when they were shipwrecked. Others may have been deliberately brought to various islands by settlers and either left to reproduce freely, or abandoned when assorted human settlements failed. While these are often referred to as "wild" horses, they are not truly "wild" in the biological sense of having no domesticated ancestors.
