Which defining characteristic of Class Mammalia is explicitly tied to the Waterbuck's survival in African temperature swings?

Answer

Being warm-blooded, allowing internal temperature regulation

The Class Mammalia encompasses animals defined by several key traits, but concerning survival across varied climates, being warm-blooded is paramount for the Waterbuck. This ability means mammals can internally regulate their body temperature, maintaining a consistent internal state regardless of external conditions. This physiological control is vital for surviving the often extreme and rapid temperature fluctuations encountered across the diverse African landscape, ensuring continuous metabolic function.
