Name:_________________________________ Date:__________ Period:______ EVIDENCE FOR EVOLUTION MASTERY TASKS TASK I: EVIDENCE FOR EVOLUTION INSTRUCTIONS: Match the “Evidence” and “How is it Evidence for Evolution?” Cutouts with the “Pictures.” Only copy the underlined information on the cutout in this column EVIDENCE PICTURE HOW IS IT EVIDENCE FOR EVOLUTION? Task II: COMPARATIVE ANATOMY CUTOUT INSTRUCTIONS: Match the Comparative Anatomy word with the correct picture and definition. Then, draw a picture that will help you remember the correct definition for each word. Word Definition and Picture These structures look similar and have the same function, BUT have evolved independently in organisms that are not closely related due to similar environments Structures of currently living animals that have diminished in size or usefulness over the course of evolution These structures look similar because they share common ancestry, but have evolved over time for different functions Draw a picture that will help you remember the difference between each word TASK III: EVIDENCE FOR EVOLUTION VOCABULARY INSTRUCTIONS: Match the Vocabulary Words with their Pictures and Definitions WORD 1) 2) 3) 4) 5) 6) 7) PICTURE DEFINITION TASK IV: EVIDENCE FOR EVOLUTION PRACTICE TEST True/False Indicate whether the sentence or statement is true or false. ____ 1. Species that have evolved from a common ancestor should have certain characteristics in common. ____ 2. The human forelimb and the bat forelimb are homologous structures. ____ 3. The theory of evolution suggests that all organisms are related by a common ancestor. Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ____ ____ ____ ____ ____ ____ ____ 4. Refer to the illustration above. The similarity of these structures suggests that the organisms a. share a common ancestor. c. evolved slowly. b. all grow at different rates. d. live for a long time. 5. Refer to the illustration above. The bones labeled “A” are known as a. vestigial structures. c. homologous structures. b. sequential structures. d. fossil structures. 6. Which of the following is a vestigial structure? a. the human tailbone c. flower color b. the bill of a finch d. fossil cast 7. Homologous structures in organisms suggest that the organisms a. share a common ancestor. c. have a skeletal structure. b. must have lived at different times. d. are now extinct. 8. Structures that no longer serve an important function are called a. inorganic. c. fossilized. b. mutated. d. vestigial. 9. The fact that all animals on earth share the same genes that control the develoment of certain segments of the embryo suggests that all animals must share a _________________ who also contained these fundamental genes. a. common ancestor. c. fossil structure. b. sequential structure. d. homologous structure. 10. The wing of a bird and the wing of an insect are ________________because they serve the same function but do not share a recent common ancestor. a. homologous structures. c. fossilized structures. b. analogous structures. d. vestigial structures. Matching: Evidence for Evolution a. b. c. vestigial structures analogous structures comparative anatomy d. homologous structures e. DNA and molecular evidence f. fossils ____ 11. the most powerful of all evidence, because the nucleotide differences or amino acid differences show, quantitatively, how similar organisms really are ___ 12. similar structures that share a common ancestor but have different functions ___ 13. tailbone, whale leg bones, appendix, etc. ____ 14. Structures that have similar function but do not share a recent common ancestor ____ 15. the preserved remains and traces of long-dead organisms. They tell us many things about past organisms: where/how/when they lived, how they died, when they became extinct, their diet, relatedness, how they evolved ____ 16. comparing the organs, bones, cells and tissues of organisms to study evolution
