Sheep are one of the four-legged ruminants with thick hair that are known to many. Sheep were one of the first types of animals to be domesticated for agricultural purposes and kept for their hair (called wool), meat and milk. The most familiar breed of sheep is the domesticated sheep (Ovis aries), which is thought to have descended from the wild moufflon from South and South-West Central Asia. For other types of sheep and their close relatives, see antelope goat. Sheep are different from goats.
