  1. Kingdom AnimaliaDeuterostome Animals

  2. Remember the 4 deteurostome development characteristics 2 worm-like groups near the base of this part of the tree (2/11): Acoelamorphs Xenoturbellids

  3. P: Echinodermata = “spiny-skinned”

  4. Echinoderm anatomy Water vascular system

  5. Another C: “sea daisies”

  6. P: Hemichordata = acorn worms & pterobranchs

  7. Important chordate characteristics somites

  8. SP: Urochordata = tunicates sea squirts (ascidians), salps, appendicularians adult larva

  9. SP: Cephalochordata = lancelets Pikaia (Wikipedia) tentacles

  10. Craniates distinctive head (skull, brain, sense organs) active predators duplicated Hox genes Hox gene clusters Fig 17-13

  11. Craniate features (cont.) new neural crest tissue more complex organs Fig 51-11 Haikouella (fossil; Wikipedia)

  12. SP:

  13. Early vertebrates agnathans conodonts Haikouichthyes (Wikipedia) ostracoderms (Wikipedia)

  14. C: Myxini = hagfishes

  15. C: Petromyzontidae (Cephalaspidomorpha) = lampreys

  16. Gnathostomes = jawed mouths Jaw evolution

  17. Gnathostomes more gene duplication forebrain larger lateral line mineralization

  18. C: Chondrichthyes = cartilaginous fish

  19. Clade Osteichthyes C: Actinopterygii = ray-fin fishes

  20. Garibaldi (CA marine fish)

  21. Clade Sarcopterygii C: Actinistia = coelocanth C: Dipnoi = lungfish

  22. Early Tetrapods (many of these added in the last 20 years) (Wikipedia)

  23. Tetrapods C: Amphibia O: Anura = frogs & toads O: Apoda = caecilians O: Urodela = newts & salamanders Ichthyostega

  24. Clade Amniotes Amniotic egg

  25. C: Reptilia

  26. C: Reptilia Birds

  27. Adaptations for flight

  28. C: Mammals Protherians = Monotremes = egg-layers spiny echidna

  29. C: Mammals Metatherians = Marsupials = pouched mammals

  30. C: Mammals Eutherians = placental mammals

  31. Convergent evolution
