Human are chordates, still they lack the main derived character of chordates. Concept introduction: The chordates during their life cycle share various derived characters like the notochord (structural support), dorsal hollow nerve cord (that give rise to the brain and the spinal cord), pharyngeal slits, and the muscular postanal tail. Many of the species posses these particular sets of characters only during their embryonic stage of development which might get reduced, non functional or disappear completely when they enter into the adult stage of life.
