The dorsal hollow nerve cord is part of the chordate central nervous system. b. In vertebrate fishes, the pharyngeal slits become the gills. c. Humans are not chordates because humans do not have a tail. d. Vertebrates do not have a notochord at any point in their development; instead, they have a vertebral column.
