1. Blood proteins in horses are chemically similar to blood proteins in monkeys. This similarity suggests that horses and monkeys: a. can interbreed b. evolved at the same time c. live in the same habitat d. have a common ancestor

2. The diagram to the right shows the gradual change over time in the anatomy of the horse. Which concept is best illustrated by the physical variations in the horse as its body size and structure change over time? a. aquired characteristicsb. artifical selectionc. intermediate inheritanced. evolution

3. Fossils of an extinct species of giant armadillo were found to be similar to a smaller species of armadillo presently inhabiting the same region. This similarity could best be explained on the basis of a. evolution from older formsb. use and disusec. inheritance of acquired characteristicsd. the heterotroph hypothesis

4. A study of the position and shape of the bones in the forelimbs of a flying squirrel, a bat, and a beaver showed that the beaver and the flying squirrel appear to be most closely related. This determination was most likely based on a study in the field of comparativea. anatomyb. biochemistryc. embryologyd. cytology

5. Fossils would most likely be found in a. sedimentary rocks that are 500 million years oldb. icebergs that are 500 billion years oldc. amber that is over 8 billion years oldd. volcanic rocks that are 50 million years old

6. The diagram to the right shows undisturbed sedimentary strata (layers) at the bottom of an ocean. The fossils found in layer B resemble the fossils found in layer A. This similarity suggests that a. the fossils in layer B were formed before the fossils in layer Ab. modern forms of life may have evolved from earlier forms of lifec. vertebrate fossils are only found in sediments d. the fossils in layer A must be more complex than those in layer B

7. According to Darwin's theory of evolution, differences between species may be the result of a. the disuse of body structuresb. the transmission of acquired characteristicsc. natural selectiond. mutagenic agents

8. Two nucleotide sequences found in two different species are almost exactly the same. This suggests that these species a. are evolving into the same speciesb. contain identical DNAc. may have similar evolutionary historiesd. have the same number of mutations

9. According to Charles Darwin, one factor that affects the evolution of a species is a. variation due to genetic mutationsb. rapid fossil formationc. survival of the fittestd. exposure to environmental pollutants

10. In the diagram of a whale below, the bones labeled "pelvis" and "femur" appear to be useless. Structures that do not appear to serve a function in modern organisms are called a. analogous structuresb. homologous structuresc. fossilsd. vestigial structures

11. Which statement best describes evolution? a. Evolution is a predictable change from simple to complex organisms.b. Evolution is a process of change through time.c. Evolution often proceeds from complex to simpler organisms.d. Evolution causes organisms to develop characteristics they need.

12. Studies of finches on the Galapagos Islands suggest that the finches' differences in beak structure were most directly due to a. adaptations of the finches to different environmentsb. the size of the island where the finches livec. mating behaviors of the different finch speciesd. acquired characteristics in the parent finches

13. Biologically similar organisms have similar DNA and proteins. This statement supports the concept of a. diversity in speciesb. acquired characteristicsc. use and disused. evolution

14. The embryos of fish, chickens, and pigs have gill slits and a tail. The presence of these features suggests that a. all these animals can swimb. these animals may have had a common ancestorc. gill slits and tails are required for embryonic developmentd. pigs developed from chickens

15. Characteristics of a species that make its members better able to live and reproduce in their environment are known as a. abiotic factorsb. biotic factorsc. favorable adaptationsd. homologous structures

16. In his theory of evolution, Charles Darwin was not able to explain the source of: a. competitionb. overproductionc. reproductiond. variation

17. Charles Darwin proposed that organisms produce many more offspring than can possibly survive on the limited amount of resources available to them. According to Darwin, the offspring that are most likely to survive are those that a. are born first and grow fastestb. are largest and most aggressivec. are best adapted to the environmentd. have no natural predators

18. One concept that supports the theory of evolution states that organisms best adapted for survival are the ones that will reproduce and pass traits on to future generations. Adaptations that can be passed on do not include a. techniques for hunting food taught by the parents of the organismb. the reflex actions of the organismc. the manner in which the organism carries out respirationd. the basic structure of the organism

19. Many biologists believe that the great number of different species of organisms which exist on the planet and the present time has resulted from billions of years of a. gel electrophoresisb. evolutionc. cloningd. recombinant DNA

20. What is the most probable reason that fossils found in lower layers of undisturbed rock are not found in upper layers of undisturbed rock in the same rock sequence? a. The development of many different organisms is part of an evolutionary process which has occurred for billions of years.b. Fossils of early organisms are much more complex than those of later organisms.c. Organisms living today show no relationship to organisms living billions of years ago.d. Changing environments on the earth have resulted in the extinction of many organisms.
