Mammals lead more active lives than reptiles primarily due to their warm-blooded nature and efficient physiological adaptations. The presence of body hair helps retain body heat, enabling mammals to maintain a stable internal temperature regardless of external conditions. Additionally, mammals possess more efficient hearts, which support a higher metabolic rate and deliver oxygen more effectively to tissues, facilitating sustained physical activity. These adaptations collectively allow mammals to thrive in a variety of environments and engage in more dynamic behaviors than reptiles.
