The key difference between vertebrates and chordates is that the vertebrates are a major subphylum of chordates that have a vertebral column while the chordates are highly evolved animals that possess a notochord, a dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail during some period of their life span.. Vertebrates are a major group of chordates regarding the … If segmentation in arthropods and chordates is an example of homoplasy, then the similar function of Hoxgenes in regulating segmental identity in vertebrates and insects is an example of parallel evolution, perhaps exaptedfrom a regionalized expression of Hoxgenes in the central nervous system of some worm-like bilaterianancestor Echinoderms are invertebrate marine animals that have pentaradial symmetry and a spiny body covering, a group that includes sea stars, sea urchins, and sea cucumbers.
