  1. Bird Vocab Quiz- Study Vocab!!!!

  2. Kingdom AnimaliaPhylum ChordataSubphylum VertebrataClass Mammalia SZ2- Students will explain the evolutionary history of animals over the geological history of Earth. Mammals evolved from early synapsid reptiles

  3. Primitive Chordate

  4. FishTwo Chambered Heart

  5. Amphibian Heart- 3 Chambers

  6. Reptilian Heart – 3 chambersCrocodile- incomplete 4

  7. Fig. 48.28

  8. Synapsids • Animals with one skull opening behind eye socket • Located in the temporal region

  9. Pelycosaurs • Synapsid reptiles from Pennsylvanian and Permian • 300-245 MYA • Body close to ground • Legs away from body • Canine like teeth Dimetron

  10. Therapsids • Before dinosaurs • Evidence suggests Mammals evolved from therapsids • Body raised off the ground • Limbs more under the body • Teeth differentiated into 3 types Lystrosaurus

  11. Cynodonts “dog tooth” • Lumbar ribs reduced or absent • Well developed secondary palate • Lower jaw reduced to one bone Thrinaxodon Cynognathus

  12. Transitional FossilThrinaxodon 250-245 mya Body divided into lumbar and thoracic regions

  13. Transitional FossilCynognathus 245-230 mya May have been endothermic and gave birth to live young Smaller than a wolf

  14. Molars, hair, glands Reduced ribs, 1 jaw bone Limbs under body, different types of teeth Canine like teeth Cladogram of Synapsids Cynodonts Mammals Therapsids Pelycosaurs Synapsid reptiles

  15. Early Mammals • Triassic • 225 MYA • Small Megazostrodon

  16. Repenomamus robustusAte Dinosaurs

  17. Kingdom Animalia • Phylum Chordata • Class Mammalia • Have fur/hair • mammary glands • Viviparous- Give birth to live young (except monotremes) • Length of time in uterus - gestation period • Extended parental care • 4 chambered heart • endothermic

  18. Mammalian Anatomical Adaptations • Muscular Diaphragm • Seven cervical(neck)vertebrae • Outer ear • Well developed brain- Largest cerebrum • Sweat glands • 6. Diphyodont teeth • Two sets • 7. Heterodont teeth • Different shapes and functions

  19. Basic Mammal

  20. Lion

  21. Rhinoceros

  22. Gorilla

  23. Chimpanzee

  24. Chimp and Human

  25. Bat

  26. Same bones, different stance

  27. Incisors

  28. Canine

  29. Premolars

  30. Molars

  31. Mammal Circulation

  32. Fig. 31.12

  33. Humans Reunite with Animals They Raised • http://today.msnbc.msn.com/id/25929574/ns/today-today_pets_and_animals/t/hugging-lions-ex-owners-reflect-his-legacy/ • http://www.treehugger.com/natural-sciences/gorilla-reunites-with-the-man-who-raised-him-video.html

  34. Mammal Classification • 14 major orders • Over 4,000 species • About half are rodents

  35. Monotremes • “cloaca” • Lay eggs • Incubate 12 days • Lick milk from mothers fur • Transitional species • Ex. Echidna, duck-billed platypus

  36. Marsupials • Pouched mammals • Birth to tiny embryo • Embryo attaches to mother’s nipple to complete development

  37. Marsupials and Monotremes in Australia • Triassic Period • Mammals evolved • Pangea • Jurassic Period • Monotremes and marsupials migrated to southern pangea • Cretaceous Period • Pangea breaks up

  38. Placental Mammals • Placenta nourishes embryo • Long gestation period • 22 months for elephant • Most successful group of mammals

  39. Placental Mammals • Competitive advantage over monotremes and marsupials • Better nutrition from placenta • Less vulnerable to predators • More advanced at birth

  40. Reptile Chorion Oxygen from air Amnion Provides private pond Yolk Sac Food for embryo Allantois Store urinary waste Mammal Chorion Form placenta to get oxygen & food from mothers blood Amnion Provides private pond Yolk sac Temporarily make RBCs Allantois Form umbilical cord Evolution of Placenta from Amniotic Egg

  41. Placental: Order Insectivora • Sharp-snout • Small • Burrow underground • Eat insects

  42. Order Chiroptera • Only Flying mammals • Elongated fingers • Echolocation • Ex. bats Importance- • Seed dispersal • Pollination • Control insects

  43. Echolocation http://animal.discovery.com/videos/fooled-by-nature-bat-vs-underwing-moth.html http://video.nationalgeographic.com/video/player/animals/mammals-animals/dolphins-and-porpoises/narwhals.html

  44. Smallest Mammal • Kitti’s hog-nosed Bat • Bumble bee size • 1.5 grams

  45. Order Xenarthra • Toothless or peg like teeth

  46. Order Carnivora • Large canine teeth • Teeth adapted to shear flesh

  47. Order Rodentia • Chisel-like incisor teeth • Continuously grow • Largest order
