Why do some animals have fur and others have feathers?
Animals have fur or feathers based on their evolutionary history and the environments they live in. Fur provides insulation, helping animals maintain their body temperature in colder climates, while feathers, found in birds, are crucial for flight, insulation, and sometimes waterproofing. Both fur and feathers also play roles in camouflage, signaling, and protection.
