Why. Do all. Animals. Not. Have. Same. Body. Feathers?

Animals have different body coverings, such as feathers, fur, scales, or skin, due to evolutionary adaptations to their environments. These adaptations help with insulation, protection, camouflage, and locomotion. For example, birds developed feathers for flight and insulation, while mammals evolved fur for warmth and protection. The diversity in body coverings reflects the variety of ecological niches and survival strategies found in the animal kingdom.
