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.
While they agree that todayâs horse probably arose from that smaller ancestor, the path was by no means direct. Instead, paleontologists have uncovered fossils that show that horse ancestors varied in size: some large early horses gave way later to smaller ones.
