Chapter 34 Chapter 34 Presentation Transcript

  • Chapter 34b: Vertebrates (mammals)
  • 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
  • Various Synapsids
  • Mammals: Monotremes
  • Monotreme: Echidna
  • Monotreme: Platypus Duck-billed platypuses are aquatic so keep their eggs warm in burrows until hatching
  • Mammals: Marsupials
  • Examples of Marsupials
  • Mammals: Eutherians Eutherians are the placental mammals, i.e., the majority of mammals are eutherians
  • Mammals: Primates The primates inhabit a branch of the mammalian phylogeny also occupied by the rodents
  • Order Primates The anthropoids include the monkeys, the apes, and us Variety of primate hands Prosimians
  • Primates
    • Primates possess numerous adaptations that allow rapid movement through trees
    • Remember all the characteristics of primates we talked about! (AND DISTINGUISH THEM FROM HUMAN CHARACTERISTICS)
  • Prosimian: A Lemur
  • Monkeys are Anthropoids
  • Order Primates The hominoids include the apes and us
  • Known or Suspect Hominids Hominids (by your text) are more closely morphologically similar to us than they are to chimpanzees
  • Simplified Tree
  • Australopithicus afarensis
  • Homo habilis
  • Homo erectus
    • H. erectus lived from approximately 1.8 to 0.5 million years ago and perhaps even longer
    • H. erectus was the most successful of the the genus Homo lineages in terms of time on Earth
    • H. erectus spread her kind throughout the old world
  • Homo erectus Pan H. erectus H. sapiens Homo
