  • A scientist refers to something as "primitive" if it has undergone the least evolution since the first vertebrates.
  • They lack paired pectoral (shoulder) and pelvic (hip) fins in addition to missing jaws.
  • Even in lampreys, their notochord remains throughout their entire existence and is never entirely replaced by a backbone. They don't have scales.
  • Hagfish are thought to be the most basic vertebrate known, living or extinct, as they lack both jaws and vertebrae.
  • The invertebrate class most closely related to vertebrates is the tunicates.
