Horses are typically single toes animals that evolved over 50 million years from many toed animals. The process of evolution also saw an increase in size, where small sized animals gave way to big ones that have been domesticated and harnessed to pull carts and tongas the world over.
Asian nomads were the first people to domesticate horses for the first time in history about 4,000 years ago. The animal's demand remained unparalleled till the steam engine came into being. They were also used in battles in the yester-years, and still find use in the armed forces.
Horses prefer tender green grass as their main food. They graze on plants and vegetation's found on the ground or anywhere else for that matter. Teeth in a horse's mouth assume a typical fashion with age and a horse's age can be deduced by a look at the typical pattern.
Female horses known as mares bear young ones known as foals. This happens after mating with male horses known as stallions. There is a gestation period of 11 months in between the two events. The foal is fully developed and can run around at birth without any instruction from its parents.
Horses have a great power of hearing. They can certainly smell things better than humans. But they are known to bank on their sense of sight rather than their ability to smell things. They have an excellent ability to taste things. Their intestines are designed in a manner that enables them to graze over fields throughout the day.
