Darwin (Erasmus) c. Earth is much older than previously thought. 4. Buffon d. Organisms can be classified according to their similarities. Choose the best answer for the statement or question. 5. To be considered members of the same species, organisms must be able to a. look alike. b. reproduce together and have fertile offspring. c. live in the same habitat. d. eat the same types of food. 6. What is incorrect about Lamarck s theory of how organisms evolve? a. He did not explain how traits were passed on to offspring. b. He did not explain why an animal would need to develop new traits. c. He did not explain why changes in the environment caused an organism s behavior to change. d. He did not explain how competition might help animals to develop traits. 7. Which scientist developed a system for classifying organisms that is still used today? a. Carolus Linnaeus b. Georges Louis LeClerc de Buffon c. Erasmus Darwin d. Jean-Baptiste Lamarck
2 8.Write the names of the theories next to their descriptions. James Hutton Charles Lyell Thomas Malthus Geologic Theory Description The idea that changes on Earth occurred by small steps over long periods of time - gradualism The idea that resources such as food, water, and shelter were natural limits to population growth [page 293] The idea that geologic processes add up over long periods of time to produce great change - uniformitarianism Vocabulary Check Fill in the blank with the word or phrase that best completes the sentence. 9. A trace of an organism that existed in the past is called a. 10. is the process of biological change by which descendants come to differ from their ancestors. 11. Events such as volcanoes, floods, and earthquakes are the basis of. 12. can be summarized by the phrase the present is the key to the past. Who s Who? Linnaeus Lamarck Buffon E. Darwin 13. Charles Darwin s poetic grandfather 14. Thought that a giraffe s long neck evolved from reaching high in trees 15. Grouped living organisms into categories based on what they looked like 16. Wrote Histoire Naturelle (Natural History) in 1749
3 SECTION 2: Darwin s Observations Choose the best answer for the question. 1.

What is variation among members of the same species called? a. adaptation b. geologic change c. interspecific variation d. intraspecific variation 3. What island chain in South America was the source of many of Darwin s insights? a. The Antipodes Islands b. The Galápagos Islands c. The Falkland Islands d. The Canary Islands 4. Darwin saw populations of various species that seemed well-suited to their environment. What did this suggest? a. The species Darwin saw were all related to each other. b. Species had been introduced to particular areas by humans on purpose. c. Species might be able to adapt to their surroundings over time. d. Some environments rarely ever change. Choose whether the statement is true or false. 5. true / false Darwin theorized that the fossils of huge animals such as Glyptodon, a giant armadillo, which looked similar to armadillos in Darwin s time, showed that living species were related to older ones. 6. true / false Darwin s discovery of marine organisms high in the mountains led him to think that ancient peoples had carried sea animals from the seaside up into the mountains. 7. true / false Darwin thought that Earth must be much older than scientists previously thought. 8. true / false If Earth was much older than previously thought, Darwin knew there had been time for species to evolve gradually.
4 Vocabulary Check Fill in the blank with the correct term from the box. variation adaptation 9. the difference in the physical traits of an individual from those of other individuals in the group to which it belongs 10. a feature that allows an organism to better survive in its environment 11. A tortoise population lives in an area with high grass. These tortoises have longer necks than tortoises that live in other areas. The long necks of the tortoises are an example of. 12. One bird in a population has a slightly thicker beak than its relatives. The bird s thicker beak is an example of in the population. SECTION 3: Theory of Natural Selection VOCABULARY artificial selection natural selection fitness heritability population Choose the best answer to the question. 1. Why did artificial selection interest Darwin? a. He hoped that humans might be able to breed for certain characteristics in animals. b. He wondered whether artificial selection could explain differences in species in nature. c. He theorized that animal and plant breeders had once visited the Galápagos Islands. d. He had noticed that humans could breed for certain characteristics in animals. 2. Why must selected traits be heritable? a. If a selected trait is not heritable, it cannot be passed down to the next generation. b. Heritable traits are those traits that farmers and breeders consider worth passing on. c. Heritable traits are common in domesticated animals that are used in breeding. d. A selected trait that is heritable is likely to make an animal easier to domesticate.
5 3. In natural selection, what must be true of traits that are passed down through generations? a. The trait must be one that members of the species like and enjoy. b. The trait must be one that members of the species have chosen to reproduce. c. The trait must be one that gives an advantage to certain individuals. d. The trait must be one that does not give an advantage to any particular individuals. 4.What important idea from Thomas Malthus inspired Darwin? a. Disease and a limited food supply keep the population smaller. b. The plants and animals that are strongest are the ones that will survive adverse conditions. c. Plants and animals are capable of inheriting characteristics from their parents. d. Species are more likely to adapt if they are subjected to varying environments. Fill in the blank with the correct word or phrase from the box. variation overproduction adaptation descent with modification 5. producing many offspring, some of which may not survive 6. individual differences that may be heritable 7. a certain variation well-suited for the environment 8. a heritable trait becoming common in a population Match the four principles of natural selection with the statements that illustrate each. 9. overproduction a. Large teeth and jaws become more common in jaguars because they are heritable characteristics. 10. variation b. Jaguars with large teeth and jaws survive longer because they can eat shelled reptiles. 11. adaptation c. By chance, some jaguars are born with slightly larger teeth and jaws. 12. descent with modification d. A jaguar may produce many offspring, but because of competition, not all of them will survive long enough to reproduce.
6 Circle the word or phrase that best completes the sentence. 13. Peter and Rosemary Grant observed natural selection acting on traits within a population of finches on the Galápagos Islands. A drought reduced the number of small, soft seeds but left plenty of large, tough-shelled seeds intact. The next year there was a(n) increase / decrease in the number of large-beaked hatchlings. 14. After several years, the supply of large seeds went down after an unusually wet period. The increase in small, soft seeds brought a(n) increase / decrease in the number of large-beaked hatchlings the following year. Vocabulary Check Circle the word or phrase that best completes the sentence. 15. Humans are the selective agent in artificial selection / natural selection. 16. The environment is the selective agent in artificial selection / natural selection. 17. The measure of the ability to survive and produce more offspring relative to other members of the population is called fitness / overproduction. 18. The ability of a trait to be passed down from one generation to the next is called adaptation / heritability. 19. All the individuals of a species that live in an area are called the population / variation. 20. Artificial / Natural selection occurs when humans deliberately breed for certain characteristics. 21. Artificial / Natural selection occurs when individuals with beneficial adaptations produce more surviving offspring than other individuals of the same species.
7 SECTION 4: Evidences of Evolution anatomy embryology fossils geography In the diagram below, fill in the type of evidence below the examples. 1. Traces of ancient animals are found in rock layers. 2. Species in one area may match species in another area that is separate but still nearby. Evidence for evolution in Darwin s time came from several sources. 3. Two different species may have larvae that are very similar. 4. The body parts of different species may have homologous structures. 5. Why is it significant that the vertebrates share several developmental homologies? Choose the word or phrase that best completes the sentence or answers the question. 6. Pelvic bones in snakes are an example of a(n) a. homologous structure. b. analogous structure. c. vestigial structure. d. fossil. 7.What conclusion can you draw from the fact that many modern whale species have vestigial pelvic and leg bones? a.
