Dr. Denardo’s Vertebrate Zoology Exam 1 Study Guide General terminology *In order to be a vertebrate, an organism must have a CRANIUM. They do NOT need to have actual vertebrae. Clade (taxon) – group of organisms with a common ancestor Sister taxon – closest relative Outgroup – close, ancient, non-relative morphy – trait Plesiomorphy – ancestral trait Apomorphy – derived trait Syn/Sym – shared trait Aut – unique trait Homologous – trait from a common ancestor Homoplasy – similar traits that are not from a common ancestor Monophyletic – all descendants of a common ancestor *For Dr. Denardo’s class, if a clade is in quotations then it is NOT a monophyletic group. Paraphyletic – share a common ancestor, but not descendants are included Polyphyletic – does not include the common ancestor of all the taxon members Pelagic – open ocean dwelling Benthic – bottom dwelling Epipelagic – dense bones and large muscle Mesopelagic – less dense bones and muscle Fusiform body – a tear shaped body Buccal pumping – rhythmically moving the mouth to draw in water Evidence for a marine origin Phylogenetics: All non-vertebrate chordates and other deuterostome invertebrate phyla are exclusively marine forms Paleontology: First fossils are found in the ocean sediments Comparative physiology: Osmolality of body fluids of out-groups match those of marine surroundings Know the clades (relative position of the different organism groups to each other) and know progression of key traits (e.g., bone, jaw, fins, etc.), also how they looked “endochondral bone” “jaws” “vertebrae” Vertebrata “cranium” Living in Water Compared to Air 1) Water is much more viscous 2) Water has lower oxygen content 3) Water is much more dense 4) Water has a higher heat capacity 5) Water has a higher heat transfer rate
