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
Types • 4 key areas of evidence: • Fossils • Morphology • Embryology • Biochemical
Fossils • Fossil- impressions or casts left behind by a prehistoric organism • Fossil record- the total of all fossils discovered
With Your Partner: • Label the fossils: • oldest youngest • simplest most complex • Answer: What does the fossil record tell us?
Fossils • Fossil record shows change over time • Predicts transitional forms
Fossils Transitional Forms of the Killer Whale
Morphology • Morphology- studying & comparing the physical structures of species • More homologous (similar & shared) features = more closely related species
Morphology • Ex: homologous limbs of human, cat, whale, bat shows close relation
Morphology • Not all similar features indicate closely related species Mammal Insect Bird
