Here's why:
* Wool Production: Sheep are specifically bred for their wool, which is a valuable commodity used in clothing and other products.
* Domestication: Sheep were domesticated thousands of years ago and are raised all over the world for their wool, meat, and milk.
Other farm animals that can be considered "woolly" include:
* Alpaca: These South American camelids produce a soft, luxurious fiber often used for clothing and blankets.
* Llama: While not as commonly bred for their fleece as alpacas, llamas also have wool that can be used for various products.
* Goat: Certain breeds of goats, like Angora goats, produce a long, silky wool known as mohair.
While these animals may not be as commonly associated with "wool production" as sheep, they all contribute to the wool industry and provide valuable fibers for a variety of uses.
