The horse is a domesticated one-toed hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of Equus ferus. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into the large, single-toed animal of today.
All horse breeds are classified into three main groups: heavy horses, light horses, and ponies. Heavy horses are the largest horses, with large bones and thick legs. Some weigh more than 2,000 pounds. Light horses are smaller horses, with small bones and thin legs.
