III. Phylogenetic Placement Work in your group to draw a phylogeny that includes the lineages from the last lab plus the Myxini, Petromyzontida, Chondrichthyes, Actinopterygii, and Sarcopterygii. Map the following traits on the inte- rior branches of the tree: • Bone • Cartilage • Closed circulation • Coelom • Ctenoid scales • Cycloid scales • Diphycercal tail • Dorsal nerve cord • Endostyle • Eyes • Ganoid scales • Gills • Heterocercal tail • Homocercal tail • Jaws • Lobe fin • Lungs • Nostrils • Notochord • Operculum • Paired appendages • Pharyngeal slits • Placoid scales • Post-anal tail • Ray fin • Swim bladder • Vertebrae

Homework: Draw it! Draw the phylogenetic tree, label all of the living things and the traits that characterize them directly on the tree:
Adi S.
Draw an evolutionary tree showing the relationships of these vertebrates: Fish, Frog, Turtle, Mouse and Kangaroo, based upon which ones share these homologous traits: Legs (all but fish), Amniotic Egg (all but fish and frog), Hair (mammals only), and pouch (marsupial mammals only). See the figure below for an example.
Courtney T.
Draw a phylogenetic tree that will indicate evolutionary trends in animal evolution. Include the following organisms in your phylogenetic tree: 1. Ascaris, 2. sponge, 3. sea anemone, 4. cockroach, 5. starfish, 6. squid, 7. spider, 8. clam, 9. butterfly, 10. grasshopper, 11. crab, 12. hydra, 13. crayfish, 14. snake, 15. mussel, 16. land snail, 17. liver fluke, 18. earthworm, 19. medusa, 20. sea cucumber. Provide all labels on your drawing with the associated number.
