OK we aren’t in kindergarten anymore. What does warm-blooded actually mean metabolically? Which version is older? If I spent the night naked in the desert, at 40 degrees all night, I’d probably die.
What about a naked lizard? Would it just slow down but not die? Naked lizard seems better. What exactly is so good about warm-blood approaches?
Also, what the fuck are birds?
Tiny dinosaurs, seem kind of like reptiles. Are they cold-blooded? I have questions.

Warm-blooded animals can maintain (within limits) a constant internal temperature. Cold-blooded animals cannot. Modern birds (which are part of the theropod group of dinosaurs) are also warm-blooded and it’s likely that at least some non-avian dinosaurs were.
