Keeping a warm, steady body temperature in animals by making heat inside the body

: endotermia

It is possible that the branch of reptiles that became mammals transduced sound in this fashion the entire time, and that competition for the function of these three bones did not occur until the advent of endothermy and the subsequent need for more rapid food processing.

Examples

The ability to maintain a constant body temperature is a key feature of endothermy in mammals.
Birds exhibit endothermy, which helps them remain active and survive in diverse climates.
Toward the end of the reign of dinosaurs, some animals (the future mammals and birds) evolved endothermy, or warm-bloodedness.

Academic text (2001)
The evolution of endothermy in certain reptiles enabled them to thrive in varying temperatures.

Morphology

endothermy = endotherm (semi-transparent) = endo + therm + y

Forming an abstract noun from the noun 'endotherm' with the suffix '-y' is a regular, recognizable process.

Etymology

Endothermy comes from endo- meaning 'inside' and thermy meaning 'heat', the same root you see in thermometer and thermal. So endothermy in animals means making and keeping heat 'inside' the body, which is why mammals and birds can stay warm in cold places.
