RECENT, 10,000 years ago to Present. The modern day species of Equus (horses, zebras, and asses) have been around for about 2 million years. They are very different from the earliest known horse, Hyracotherium, otherwise knows as Oehippus, or âDawn Horseâ. This ancient horse was a small, dog-sized creature that lived from 55 to 45 million years ago.
Most horses are domesticated, and are protected by people from their predators, or natural enemies. Almost all horses that live in the wild are descended from ancestors that once belonged belonged to people. These domesticated ancestors escaped and became wild again. Thousands of years ago, before horses were domesticated, their main predator was the wolf. Wolves were one of the few animals that were fast enough and smart enough to chase, catch, kill and eat horses. Even now, the wolf is one of the few predators that eats wild horses. Grizzly bears and mountain lions may also occasionally attack a horse.
