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.
Look what's happened to the horse.â âWhat has happened to the horse?â I asked. âWell, over a period of 60 million years it's grown from being a small fox-like animal only 61 centimeters tall to the modern-day horse that stands more than two meters high.And it's lost all its toes too.â.he horse series is often presented as proof of Evolution. The number of toes in foreleg and hind leg supposedly decreased as the horse evolved, and the size supposedly increased from a small doglike horse to a large modern horse.
