Introduction: The Mystery of Reptile Cold-Bloodedness
Reptiles have long been known for their cold-bloodedness, which means their body temperature is regulated by the environment rather than by internal mechanisms. However, the evolutionary reason for this trait has been a mystery. Understanding the basis for reptile cold-bloodedness can provide insights into the evolution of reptiles and their relationships with the environment.
Understanding the Basics of Reptile Metabolism
Reptiles have a lower metabolic rate than warm-blooded animals, which means they use less energy to maintain their bodily functions. They have a slower heart rate, lower oxygen consumption, and a simpler respiratory system than warm-blooded animals. Reptiles also have a unique system of blood circulation, where their blood flows through their lungs and then directly to their body tissues, bypassing the heart. This allows reptiles to conserve energy and survive with less food and oxygen intake than warm-blooded animals.
