Review Chapters 14 and 15

1. Review Chapters 14 and 15 Evolution

2. Which answer best shows an animal's adaptation to the tropical rain forest? • A squirrels tail • The long neck of an ostrich • Camouflage in a tree snake • Stripes of a zebra

3. A population of birds separates and becomes reproductively isolated, due to different mating patterns. What is this process called? • Bottleneck effect • Sexual selection • Speciation

4. A change in a sequence of DNA that can lead to evolution is called a • Polygenic trait • Fitness • Mutation • Bottleneck effect

5. What is it called when populations become separated by rivers or mountains, like how squirrels are on the North and South Rims of the Grand Canyon? • Temporal isolation • Geographic isolation • Behavioral isolation • Moving day

6. Most fossils form in • Volcanic rock • Forests • Sedimentary rock • Tree sap

7. Due to __________, both ends have higher fitness than the middle. • Disruptive selection • Sexual selection • Directional selection

8. What types of structures develop from similar tissues in early developmental stages of the organism, but meet different needs in the adult? • Convergent structures • Analogous structures • Homologous structures

9. Examples of fossils include preserved • Eggs • Footprints • Body parts • All of the above

10. Which of the following is the best explanation of why bat wingsand dog forelegsare evidence of evolution? • Homologous structures indicate a common ancestor • Vestigial structures indicate a common ancestor • Analogous structures indicate a common ancestor • They both have similar functions.

11. Darwin’s theory of evolution suggests that • Extinct species are very different than living species • Different species can interbreed • Species change over time • Species change when they want to

12. Which of the following describes convergent evolution? • Species are similar in appearance and behavior, but not closely related. • Closely related species are different in appearance and behavior. • Species are different in appearance and behavior, and are unrelated • Species are similar in appearance and behavior, and are closely related.

13. What should the half-life of the isotope used to date the age of Earth at 4.6 billion years be? • 1 billion years • 100,000 years • 5730 years

14. Which term best describes the following structures? • Vestigial structures • Analogous structures • Homologous structures

15. Genetic drift tends to more strongly affect populations that • Have unchanging allele frequencies • Are small • Are very large

16. Structures that are similar in appearance and function, but differ anatomically are said to be • Analogous structures • Vestigial structures • Homologous structures

17. Homologous structures are a sign of • Adaptive Radiation • Directional Selection • Convergent Evolution

18. The human tail bone and the leg bones of a whale are examples of which type of structure? • Homologous structures • Vestigial structures • Convergent structures • Analogous structures

19. Which of the following is a correct statement about the relationship between natural selection and evolution? • Natural selection is one mechanism (way) of how evolution works • Natural selection and evolution are the same thing • Natural selection results from evolution • Evolution is how natural selection works

20. How well are you understanding the material? • 1 – Not very well • 2 – A little • 3 – Getting it, but need to study a lot • 4 – Pretty well • 5 – Very well: I could explain it 
