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.
There is only one species of domestic horse, but around 400 different breeds that specialize in everything from pulling wagons to racing. All horses are grazers. While most horses are domestic, others remain wild. Feral horses are the descendents of once-tame animals that have run free for generations.
