Understanding the evolution of endothermy requires the resolution of a paradox: Increasing the resting metabolic rate can provide heat to raise the body temperature, but without insulation (hair or feathers) that heat is rapidly lost to the
environment. But a layer of insulation does not benefit a vertebrate unless the animal has a high metabolic rate. Discuss the evidence suggesting that Mesozoic synapsids and sauropsids had developed both high metabolic rates and insulation, and identify the puzzling gaps in the information currently available.
