of Equus ferus. It is an odd-toed ungulate mammal belonging to the
taxonomic family Equidae. The horse has evolved over the past 45 to
55 million years from a small multi-toed creature, Hyracotherium, into
the large, single-toed animal of today. Humans began to domesticate
horses around 4000 BC, and their domestication is believed to have
been widespread by 3000 BC. 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,
as this term is used to describe horses that have never been
domesticated, such as the endangered Przewalski's horse, a separate
subspecies, and the only remaining true wild horse. 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.free images of horses
