One of these animals is a mammal called "Hyracotherium". This animal lives in the Eocene Age. This animal is thought to be the ancestor of a horse that lives now. "Hyracotherium" is a herbivorous animal that has complete forty-four teeth with a low crown, these teeth are used to chew leaves from trees or shrubs. first known, many scientists believe that this mammal has reduced various types of horses that exist today. "Hyracotherium" has adapted well to living in grasslands. This mammal has four fingers on each leg. These fingers serve as a buffer to hold almost all of its body weight. "Hyracotherium" is about the same size as a mouse deer. In the Oligocene Period, "Hyracotherium" went extinct. However, these mammals have descended from their descendants called "Mesohippus". "Mesohippus" is larger than "Hyracotherium". The "Mesohippus" body structure shows that these animals have adapted very well to living on grasslands, this is indicated by the reduced number of fingers on each "Mesohippus" foot to three fingers on each leg. The middle finger is also bigger than the other fingers. In addition, this animal also has stronger and more agile legs than "Hyracotherium". This animal has a rather long neck. In his mouth, several pre-molars teeth were found which almost developed into molars. Teeth like this will certainly increase their ability to chew food.

In the middle of the Miocene Period, a horse-like life called "Merychippus". This horse species is thought to be descended from "Mesohippus". Like his ancestors, "Merychippus" still has a rather long neck that is typical. Allegedly, this long neck serves as a tool as he grazes, so he can graze calmly in a standing position. "Merychippus" has three fingers on its hind legs, and four fingers on its front legs. The "Merychippus" foot developed into a long leg, somewhat different from the legs that horses have today.
