The reptile clade includes the tuatara, lizards, snakes, turtles, crocodilians, and birds. Birds are considered reptiles now to make the phylogenetic tree monophyletic. Opposite to popular belief, the reptile clade is not entirely ectothermic; ( the absorption of external heat as the main source of body heat) birds are endothermic, capable of keeping the body warm through metabolism.

The correct order in which vertebrates evolved is fish, amphibians, reptiles, birds, and then mammals. Fish were the first vertebrates to appear, followed by amphibians that adapted to life on land. Reptiles evolved next, leading to the development of birds and eventually mammals. Thus, the correct sequence is fish, amphibians, reptiles, birds, and mammals.
