  1. Question of the Day Question: Name the scientist this cartoon supports and describe his ideas. Answer: … … … 3’s Turn In: p. 453 A.Q. 1ab, 2ab

  2. Notes: Evidence for Evolution

  3. Types • 4 key areas of evidence: • Fossils • Morphology • Embryology • Biochemical

  4. Fossils • Fossil- impressions or casts left behind by a prehistoric organism • Fossil record- the total of all fossils discovered

  5. With Your Partner: • Label the fossils: • oldest  youngest • simplest  most complex • Answer: What does the fossil record tell us?

  6. Fossils • Fossil record shows change over time • Predicts transitional forms

  7. Fossils Transitional Forms of the Killer Whale

  8. Fossils

  9. Morphology • Morphology- studying & comparing the physical structures of species • More homologous (similar & shared) features = more closely related species

  10. Morphology • Ex: homologous limbs of human, cat, whale, bat shows close relation

  11. Morphology • Not all similar features indicate closely related species Mammal Insect Bird

  12. Using Fossils & Morphology:Caminacules
