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.
