Most of the evolution of horses was identified and traced by studying these changes in tooth shape and structure. The second major factor that affected the evolution of the horse was the emergence of more effective competitors, such as the artiodactyls (herbivores like camels, deer, and bison), and swifter predators, especially the cats with their saberlike canine teeth. These swift and efficient predators found the smaller, forest-dwelling horses to be easy prey, resulting in the swift extinction of the horses.
