but only in comic books is there enough radiation from the extra radioactivity to really make a difference. The wildfire hypothesis is credible, and the large load of soot in the odd layer marking the extinction of the dinosaurs argues in favor of the wildfires having occurred.Points Earned: 0/1Correct Answer: AYour Response: D 7. Which of the following is not a part of the modern theory of evolution? A. Diversity exists within a species, and “experiments” that tend to promote diversity sometimes occur during reproduction. B. Evolution proceeds in the direction desired by members of a generation. C. Children are more similar to their parents than to other individuals from their parents’ generation. D. A “successful experiment” during reproduction is one that increases the ability of an individual to have children who survive to have children. E. If a reproductive “experiment” is successful, it will be passed to more and more children in successive generations until all members of a population have it. No matter how hard you and your friends wish that your children will be born with the ability to fly unassisted, the kids will have to use airlines like the rest of us. All the rest of these contribute to evolution. Points Earned: 0/1 Correct Answer: B Your Response: E 8. A widely accepted scientific idea usually is based on: A. Results of one experiment or observation that refuted old ideas and supported the correctness of the new idea. B. Received wisdom from sacred books. C. Socially conditioned ideas of scientists without reference to observations or experiments. D. Diet Pepsi ads. E. An interlocking web of important experimental results or observations that support the correctness of the idea. At last observation, Pepsi commercials were not highly scientific, even if science is involved in figuring out what sells. It is a romantic notion that you could overturn great knowledge with a single observation; however, observing nature is not easy, and nature occasionally fools us (you can, rarely, flip an honest coin twenty times and get twenty heads), so if a single observation disagrees with a lot of other information, that single observation will be checked in various ways to see if the new result “stands up” before the older body of knowledge is discarded. Before an idea gains wide currency, that idea is tried in various ways, in many labs, in many places in nature, while models are run and theory is developed. The interlocking of all of these provides the confidence that scientists can use in doing things successfully. Although received wisdom

from sacred books can be used for inspiration, scientific ideas must be tested against nature. Social scientists have quite rightly learned that scientists are affected by their prejudices, their funding sources, their mating habits, and other things, and that the path of science is not nearly the straight-ahead road to understanding presented in some textbooks. Unfortunately, some of
