    3 24 Evidence For Evolution 3 24 Evidence For Evolution Presentation Transcript

    • Launch
      • Evolution is all around us in society.
        • Pick one example of how you can see the concept of evolution in society and explain the different levels.
    • Quiz Results
      • B1- 80%
      • B2- 80%
      • B3- 80%
      • B5
    • New Quiz Set-up
      • Tuesdays will be content quizzes
      • Thursday will be vocab quizzes
        • Definitions, examples, non-examples
    • Fossil Evidence
      • Shows numbers of extinct animals
      • Shows similarities between extinct animals and animals that are alive today
      • The earth’s layers show a time scale of species and when they appeared on earth (and when they died out)
    • Picture of Fossil
    •  
    • Homologous structures
      • Structures that have the same/similar function that came from a common ancestor
    • Analogous Structures
      • Structures that have the same function, but evolved separately .
      • Ex:
        • The wings in dinosaur bats and birds
    • Vestigial Structures (Organs)
      • Organs or parts that seem to have no longer have a function Whales have pelvic bones that do not attach to legs
    • Biochemistry and DNA
      • When comparing the DNA of one species to another, more similarities are found in species that are more closely related
    • Embryological Development
      • Embryos of different species develop in almost identical ways.
    •  
    • Apply your knowledge
      • How might using anti-bacterial lotions and hand sanitizers be the theory of evolution in action?
