Transcript

  1. Evidence for Evolution (pg 4)
  2. Evidence for Evolution (pg 4)1. Fossil record: Fossils show evolutionarychanges and intermediate forms
  3. 2. Comparative Anatomy: Species that areclosely related share homologous structures
  4. 2. Comparative Anatomy: Species that areclosely related share homologous structures• Example: The forelimbs of mammals all sharethe same basic bone structure
  5. 2. Comparative Anatomy: Species that areclosely related share homologous structures• Example: The forelimbs of mammals all sharethe same basic bone structure
  6. 2. Comparative Anatomy: Species that areclosely related share homologous structures• Example: The forelimbs of mammals all sharethe same basic bone structure
  7. Worksheet
  8. 3. Vestigial structures = body structuresthathave lost their primary function
  9. 3. Vestigial structures = body structuresthathave lost their primary functionExample: Hind limbs in whales and snakes
  10. 3. Vestigial structures = body structuresthathave lost their primary functionExample: Hind limbs in whales and snakesHuman Examples: Appendix, Tailbone, Goosebumps
  11. Diagram (pg 5)
  12. 4. Comparative Embryology: In early stages, allanimal embryos look alike, suggestingcommon ancestry
  13. 4. Comparative Embryology: In early stages, allanimal embryos look alike, suggestingcommon ancestryExample: Young human embryos have gill slitsand a tail
