Why do some animals have hooves?

Hooves are an adaptation found in certain mammals, such as horses, deer, and cattle, that help them move efficiently across different terrains. Hooves provide support and protection for the feet, allowing these animals to run at high speeds, travel long distances, and navigate through various environments. Hooves are made of keratin, the same material as human nails, and are designed to withstand wear and tear. The structure of hooves also aids in absorbing the shock from running and helps distribute the animal’s weight evenly across its limbs.
