3 24 Evidence For Evolution

  1. 1. Launch <ul><li>Evolution is all around us in society. </li></ul><ul><ul><li>Pick one example of how you can see the concept of evolution in society and explain the different levels. </li></ul></ul>
  2. 2. Quiz Results <ul><li>B1- 80% </li></ul><ul><li>B2- 80% </li></ul><ul><li>B3- 80% </li></ul><ul><li>B5 </li></ul>
  3. 3. New Quiz Set-up <ul><li>Tuesdays will be content quizzes </li></ul><ul><li>Thursday will be vocab quizzes </li></ul><ul><ul><li>Definitions, examples, non-examples </li></ul></ul>
  4. 4. Fossil Evidence <ul><li>Shows numbers of extinct animals </li></ul><ul><li>Shows similarities between extinct animals and animals that are alive today </li></ul><ul><li>The earth’s layers show a time scale of species and when they appeared on earth (and when they died out) </li></ul>
  5. 5. Picture of Fossil
  6. 7. Homologous structures <ul><li>Structures that have the same/similar function that came from a common ancestor </li></ul>
  7. 8. Analogous Structures <ul><li>Structures that have the same function, but evolved separately . </li></ul><ul><li>Ex: </li></ul><ul><ul><li>The wings in dinosaur bats and birds </li></ul></ul>
  8. 9. Vestigial Structures (Organs) <ul><li>Organs or parts that seem to have no longer have a function Whales have pelvic bones that do not attach to legs </li></ul>
  9. 10. Biochemistry and DNA <ul><li>When comparing the DNA of one species to another, more similarities are found in species that are more closely related </li></ul>
  10. 11. Embryological Development <ul><li>Embryos of different species develop in almost identical ways. </li></ul>
  11. 13. Apply your knowledge <ul><li>How might using anti-bacterial lotions and hand sanitizers be the theory of evolution in action? </li></ul>
  12. 14. YouTube <ul><li>http://www.youtube.com/watch?v=F1ucXmzcfmI </li></ul>
  13. 15. Vocab <ul><li>vestigial structure </li></ul><ul><li>homologous structure </li></ul><ul><li>analogous structure </li></ul><ul><li>evolution </li></ul><ul><li>loss-of-function mutation </li></ul><ul><li>gain-of-function mutation </li></ul><ul><li>beneficial mutation </li></ul><ul><li>negative mutation </li></ul><ul><li>Theory </li></ul><ul><li>Creationism/Intelligent Design </li></ul><ul><li>heritable </li></ul><ul><li>mutagen </li></ul><ul><li>genetic variation </li></ul><ul><li>somatic mutation </li></ul><ul><li>germline mutation </li></ul><ul><li>homologous chromosome </li></ul><ul><li>crossing over </li></ul>
