The question whether Przewalski's horse is an ancestor of any domestic horse is still being debated, though it can interbreed with domesticated horses to hybridize and produce fertile offspring. Of the caballine equines, E. ferus, only E. ferus ferus, also known as the European wild horse, shares ancestry with the modern domestic horse. [1]
Therefore, the domestic horse today is classified as Equus ferus caballus. No genetic originals of native wild horses currently exist. The Przewalski diverged from the modern horse before domestication. It has 66 chromosomes, as opposed to 64 among modern domesticated horses, and their Mitochondrial DNA (mtDNA) forms a distinct cluster. [15]
All domesticated horses need regular hoof trims, regardless of use. Horses in the wild do not need hoof trims because they travel as much as 50 miles (80 km) a day in dry or semi-arid grassland in search of forage, a process that wears their feet naturally.
Horse breeds are loosely divided into three categories based on general temperament: spirited "hot bloods" with speed and endurance; "cold bloods", such as draft horses and some ponies, suitable for slow, heavy work; and "warmbloods", developed from crosses between hot bloods and cold bloods, often focusing on creating breeds for specific ...
But the timing of equine domestication and the subsequent broad use of horse power has been a matter of contention. An analysis of genome data from 475 ancient horses and 77 modern ones is ...
Horses evolved from small mammals whose survival depended on their ability to flee from predators (for example: wolves, big cats, bears). [2] This survival mechanism still exists in the modern domestic horse. Humans have removed many predators from the life of the domestic horse; however, its first instinct when frightened is to escape.
It is large compared to the otherwise similar Mongolian horse and Przewalski's horse. [2]: 340 It is noted for its adaptation to the extreme cold climate of Yakutia, including the ability to locate and graze on vegetation that is under deep snow cover, [3] and to survive without shelter in temperatures that reach −70 °C (−94 °F).

Many prehistoric horse species, now extinct, evolved in North America, but the wild horses of today are the offspring of horses that were domesticated in southern europe. [2] In the Western United States, certain bands of horses and burros are protected under the Wild and Free-Roaming Horses and Burros Act of 1971. There are about 300,000 ...
