The video explains that humans belong to the phylum Cordata due to the presence of a notochord during embryonic development, which later becomes the spinal cord. Other chordates, like hagfish and lampreys, retain their notochord into adulthood. All chordates share features such as a dorsal nerve cord, pharyngeal slits, a muscular tail, and a closed circulatory system with a heart. Examples of chordates include fish, amphibians, reptiles, birds, and mammals.
