Reconstruction, left forefoot skeleton (third digit emphasized yellow) and longitudinal section of molars of selected prehistoric horses Skeletal evolution. The evolution of the horse, a mammal of the family Equidae, occurred over a geologic time scale of 50 million years, transforming the small, dog-sized, [1] forest-dwelling Eohippus into the ...
DOM2 horses also occur in some areas prior to the earliest evidence for chariots, suggesting that both horseback riding and chariot use were factors in expansion. [4] Genetic data may also provide clues as to why this particular domestication event had far more widespread impact than other domestication events in Botai, Iberia, SIberia and ...
The horse (Equus ferus caballus) [2] [3] 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
Restoration by Charles R. Knight. Mesohippus had longer legs than its predecessor Eohippus and stood about 60 cm (6 hands) tall.This equid is the first fully tridactyl horse in the evolutionary record, with the third digit being longer and larger than its second and fourth digits; Mesohippus had not developed a hoof at this point, rather it still had pads as seen in Hyracotherium and Orohippus ...
Equidae (commonly known as the horse family) is the taxonomic family of horses and related animals, including the extant horses, asses, and zebras, and many other species known only from fossils. The family evolved more than 50 million years ago, in the Eocene epoch, from a small, multi-toed ungulate into larger, single-toed animals.
Pliohippus (Greek πλείων (pleion, "more") and ἵππος (ippos, "horse")) [1] is an extinct genus of Equidae, the horse family. Pliohippus arose in the middle Miocene, around 15 million years ago. The long and slim limbs of Pliohippus reveal a quick-footed steppe animal. While some specimens have one toe per leg, others have three (the ...

The history of horse domestication has been subject to much debate, with various competing hypotheses over time about how domestication of the horse occurred. The main point of contention was whether the domestication of the horse occurred once in a single domestication event, or that the horse was domesticated independently multiple times.
