18-2 Modern Evolutionary Classification Name_____________________________________ 1. See Fig 18-6--- Based on appearance alone, which is more similar: [ barnacles and limpets] or [ barnacles and crabs] 2. What is phylogeny? _____________________________________________________________________ 3. The strategy of grouping organisms based on their evolutionary history is called ______________________ classification. 4. Based on evolutionary classification, which pair is more similar: [ barnacles and limpets] or [ barnacles and crabs] (underline pair) 5. Name two characteristics that barnacles share with crabs: _________________________________________________________ 6. Characteristics that appear in recent parts of a lineage but not in its older members are called ____________________________ characters. 7. What is a cladogram? __________________________________________________________________ 8. Name a gene that both humans and yeast both have: ___________________________________________ 9. This gene is evidence that humans and yeast share a common ______________________________________ 10. What peculiar behavior is found only in storks and american vultures? _______________________________ 11. DNA evidence indicates that the american vulture is more closely related to a stork than to an ______________________________________ 12. A ______________________ clock is used to estimate the length of time that two organisms have been evolving independently. 13. This model relies on measuring the number of _____________________________________ that have occurred in DNA. 18-3 Kingdoms and Domains 14. What were the two kingdoms that were proposed by Linnaeus? __________________________________________________ 15. List the six kingdoms used in modern classification: ____________________________________________________________ _________________________________________________________________________________________________________ 16. A domain is [ larger / smaller ] than a kingdom. 17. What domain includes plants, animals, protists and fungi? ____________________________________________________ 18. Members of the Domain _______________________________________________ live in extreme environments. 19. The domain Eukarya constists of all the organisms that have a ______________________________________________. 20. What do members of the Kingdom Fungi eat? _______________________________________________ 21. Name a unicellular fungi: ____________________________________ 22. What kingdom contains multicellular autotrophic organisms? __________________________________ 23. What does the term "nonmotile" mean? _________________________________________________ 24. What kingdom contains multicellular heterotrophic organisms? _________________________________ 25. See Fig 18-13 - Which domain includes organisms from more than one kingdom? ____________________
