The horse (Equus ferus caballus)[2][5] is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of Equus ferus. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, which are horses that never have been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior.
Draft horses are large and strong. They are used for heavy work like pulling carts, plows, or logs. Some examples of draft horses are: Clydesdale Shire Percheron Belgian
Light horses are smaller and faster than draft horses. They are often used for riding, racing, and other activities. Some well-known light horses include: Arabian Thoroughbred Quarter Horse Appaloosa
Feral Horses Feral horses live in the wild but are descendants of domestic horses. They are often admired for their beauty and strength. Examples include: Mustang (found in North America) Brumby (found in Australia)
