What are the classics of vertebretes?

The classics of vertebrates typically refer to the major groups of animals within the subphylum Vertebrata, which includes jawless fish (like lampreys), cartilaginous fish (like sharks and rays), bony fish, amphibians, reptiles, birds, and mammals. Each group represents significant evolutionary adaptations and ecological roles. These vertebrates are characterized by a backbone, a complex nervous system, and often have specialized organs and limbs adapted to their environments. The study of these groups provides insights into evolutionary Biology and the diversity of life on Earth.
