Reptile: History, Evolutionary history & Classification

Reptiles, as commonly defined, are tetrapod vertebrate animals with an ectothermic metabolism and amniotic development. Reptiles traditionally comprise four orders: Testudines (turtles), Crocodilia (crocodiles, alligators and gharials), Squamata (lizards and snakes) and Rhynchocephalia (tuatara), with about 12,000 extant species listed in the Reptile…
