    1. 1. Chapter 34b: Vertebrates (mammals)
    2. 2. Mammalia Though mammals predate the dinosaurs, it was only once the dinosaurs were mostly gone that the mammal adaptive radiation began in earnest The defining features of extant mammals are their hair, mammary glands, larger brains, differentiated teeth, modified jaws, etc. The mammal lineage predates the mammals with the synapsids: the mammal-like reptiles
    3. 3. Various Synapsids
    4. 4. Mammals: Monotremes
    5. 5. Monotreme: Echidna
    6. 6. Monotreme: Platypus Duck-billed platypuses are aquatic so keep their eggs warm in burrows until hatching
    7. 7. Mammals: Marsupials
    8. 8. Examples of Marsupials

    12. 12. Primates <ul><li>Primates possess numerous adaptations that allow rapid movement through trees </li></ul><ul><li>Remember all the characteristics of primates we talked about! (AND DISTINGUISH THEM FROM HUMAN CHARACTERISTICS) </li></ul>
    13. 13. Prosimian: A Lemur
