2. Select the best example of change caused by a transformational process.A mutation in a single Staphylococcus bacterium allows it to resist the most effective antibiotic prescribed by doctors.
3. Which of the following is not an example of the three basic types of change that can cause biological evolution?a.*A mutation in the skin cell of a human causes an area of lighter pigmentation. b. Natural selection in a species of lizard based on the fitness of individuals with different phenotypes. c. New mutations in HIV that allows it to circumvent the human immune system. d. Genetic drift removing random diversity from a beetle species.
4. Variational processes __________________ the diversity of a population.decrease
5. The US Supreme Court has ruled that creationism should not be taught in public schools. These rulings have centered around two main arguments: the non-scientific (non-falsifiable) nature of creationism and ___________________.separation of Church and State

8. The earth was created by a supernatural being during six 24 hour periods about 6000 years ago. The preceding description best fits which type of creationism?Young Earth Creationism
9. Theodosius Dobzhansky "Nothing in biology makes sense except in the light of evolution."
10. Lamarck“All known living bodies are sharply divided into two special kingdoms, based upon the essential differences which distinguish animals from plants, and in spite of what has been said, I am convinced that these two kingdoms do not really merge into one another at any point.”
11. Charles Darwin "As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected.”
12. Thomas Malthus “The power of population is indefinitely greater than the power in the earth to produce subsistence for man.”
13. Stephen Gould “I believe, with all my heart, in a respectful, even loving, concordat between the magisteria of science and religion . . .”
14. Which of the following events had a great impact on Charles Darwin and his ideas regarding the mechanism of evolutionary change in populations?Darwin was the naturalist on the HMS Beagle and observed a wide variety of wildlife on the Galapagos Islands that were somewhat similar to mainland species and yet definitely different species.
15. Nodes on a phylogeny represent the common ancestors of the species at the tips of the branches.True
16. What is the scala naturae?A hierarchical system that attempts to organize life on earth based on its complexity, with simple organisms at the bottom and more complex organisms at the top.
17. What scientific theory are Charles Lyell and James Hutton most closely associated with?Uniformitarianism
18. Why did it take so long to unite the ideas of Mendel and Darwin?Mendel’s work was not recognized as valuable and important until the 20th century.
19. What is the “green revolution” and which prediction has it allowed us to postpone?Modern agricultural methods. Thomas Malthus’ prediction regarding population growth increasing much more quickly than resources to support that population.
When newly formed a rock has 64 ug per kg of a radioactive element an ancient sample of the same rock only has 4 ug per kg of that same radioactive element. If the half-life of this element is 100 million years, how old is the ancient rock? 400 million years
