- 4. Multiple ChoiceWhat does Darwin's theory of evolution suggest?species change over timeextinct species are not related to living speciesdifferent species can interbreedanimals that look alike are most closely related
- 5. Multiple ChoiceSome organisms that share a common ancestor have features that have different functions, but similar structures. These are known asvestigial structuresanalogous structureshomologous structuresfossil structures
- 6. Multiple ChoiceIf modern organisms have a lot of homologous structures, what inference might paleontologists make about those organisms?They are reptilesOne organism evolved from the other.The organisms have a common ancestor
- 7. Multiple ChoiceWhich is not evidence for evolution?many animals have homologous structures due to common ancestryMany animals have vestigial structures from an ancestorWe can observe changes in life forms by observing the fossil recordAll of these are evidence for evolution
