The earliest chordates were all marine animals like tunicates and lancelets. Chordates are a phylum of animals. The birds are simply a twig on the dinosaurs’ branch of the tree of life. The fossil record indicates that many other clades evolved to give rise to the class Amphibia. Primitive chordates evolved small slits opening into the pharynx. The majority view is that this ancestor had a CNS with a brain that gave rise to the chordate CNS and, with loss of a discrete brain, to one of the two hemichordate nerve cords.
