We sometimes assume that reptiles cannot be as smart as mammals because they are exothermic (cold-blooded) rather than endothermic (warm-blooded), and the brain is a high metabolic area. Here, though, we find some surprises. Reptiles lack some brain structures found in mammals but they can use what they’ve got for behavior that we would describe as intelligent: Crocodilians (alligators and crocodiles) have been reported to use sticks as decoys, play, and work in teams. Exothermy slows intelligence but does not absolutely prevent it: Anole lizards were found as capable as tits (birds) in a problem-solving test for a food reward. But the anoles, being exothermic, don’t need Read More ›
