A scientific hypothesis a) is a statement that can refer to anything b) is a statement that cannot be refuted by future discoveries c) is a statement about the natural world that scientists can attempt to falsify d) is comprised of several contributing theories 6. When scientists say that a hypothesis must be falsifiable, they are stating that a) they believe that this hypothesis will eventually be shown to be incorrect b) the hypothesis must in some way be testable c) the hypothesis in question is the simplest of all current explanations d) they have ruled out the possibility of proving that particular hypothesis 7. During the European Middle Ages, the dominant scientific explanations for life and for the process through which the earth arose were based on a) empirical observation and experimentation b) religious scriptures c) the scientific method d) the concepts of catastrophism and uniformitarianism

2 2 8. Which of the following statements best defines the idea of uniformitarianism? a) species are immutable b) the world is periodically destroyed by catastrophes c) creatures can transform themselves and their offspring will then inherit those transformations d) the geologic processes that drive the world today have always done so 9. Science is considered self-correcting because a) hypotheses are based upon observations of the natural world b) the testing of a hypothesis can result in the rejection of previous hypotheses c) theories can be modified or replaced subject to new findings d) all of the above 10. One of the most important of Charles Darwin's observations was that a) nature is full of variation b) natural selection is very different from artificial selection c) populations have only a limited potential for growth d) creatures within a species all tend to look the same 11. From an evolutionary perspective, the "fitness" of an individual is expressed through a) the number of offspring it contributes to the next generation b) a visible characteristic, such as its size, strength, or speed c) the number of times it has copulated d) the amount of bling it has accumulated 12. Before about 1600, most Europeans believed that a) all species of life had evolved from one common ancestor b) most species of life had already gone extinct c) all forms of life were created by God at the time creation and had not changed since d) evolution was the result of natural selection acting upon genetic variation 13. The synthetic theory of evolution a) merged the ideas of James Hutton with those of Charles Darwin b) emphasized the role of microevolution over macroevolution c) combined Darwin s theory of natural selection with Mendel s ideas about inheritance d) reconciled traditional religious notions with modern scientific thinking 14. The English author Thomas Malthus provided Charles Darwin with the insight that a) all species eventually go extinct b) more individuals are born into a species than will reach adulthood c) some traits give the individuals who possess them a disadvantage d) creatures can will themselves to change 15.

Charles Darwin revolutionized our thinking about living organisms because he a) explained how it is that living organisms are able to reproduce b) argued that natural forces are sufficient to explain the diversity of life c) disproved the notion that organisms are truly different d) discovered the rules of genetic inheritance

3 17. In his work on pea plants, Gregor Mendel observed that the height of a plant was sometimes tall and sometimes dwarf. This observation led him to eventually a) develop his ideas about genetic dominance and recessiveness b) discover the principle of allelic transformation c) postulate the law of random variation d) develop an improved method for growing peas 18.
