A Brief History of Horses. By 55 million years ago, the first members of the horse family, the dog-sized Hyracotherium, were scampering through the forests that covered North America. For more than half their history, most horses remained small, forest browsers.
A common example of the feral horse type is the Mustang. The Mustang is, in part, descended from the Iberian horses brought to the Americas by the Spanish, but most herds also have ancestry from other breeds. Therefore, the famous Mustang hoof strength is in part a result of natural selection and environment.
