The horse is a large odd-toed ungulate mammal, one of ten modern species of the genus Equus. Horses have long been among the most economically important domesticated animals; however their importance has declined with the introduction of mechanization. The horse is a prominent figure in the ideals of religion, mythology, and art and plays an important role in transportation, agriculture, and warfare. Horses also serve as a source of food, fuel, and clothing. Most breeds of horses are able to perform work such as carrying humans on their backs or be harnessed to pull objects such as carts or plows. However, horse breeds were developed to allow horses to be specialized for certain tasks; lighter horses for racing or riding, heavier horses for farming and other tasks requiring pulling power. Some horses, such as the miniature horse, can be kept as pets. In some societies, horses are a source of food, both meat and milk; in others it is taboo to consume them. In industrialized countries, horses are predominantly kept for leisure and sporting pursuits, while in other parts of the world they are used as working animals.
