Textbook Question
Chapter 1, Problem 17TYK
SCIENTIFIC THINKING Suppose that in an experiment similar to the camouflage experiment described in Module 1.5, a researcher observed and recorded more total predator attacks on dark-model mice in the inland habitat than on dark models in the beach habitat. From comparing these two pieces of data, the researcher concluded that the camouflage hypothesis is false. Do you think this conclusion is justified? Why or why not?

Suppose you spot two species of birds feeding side by side, eating seeds from the same plant. You begin to wonder whether competition is at work. Describe how you might design scientific research to address this question. What observations would you try to make at the outset? Would you try to manipulate the system to test your hypothesis that the two birds are competing? If so, how?
If we want to predict how many hours a day some species sleeps, which of these questions would be most helpful in making that prediction? a. What color is the animal? b. Does the animal live north or south of the equator? c. What does the animal eat? d. How intelligent is the animal?
Character displacement occurs when strong selective pressure by a predators causes evolution in the prey’s defense strategy. Is this True or False?

- Zebras live in large herds. When attacked by a predator, such as a lion, some individual zebras will engage in combat with the lion, rather than trying to escape. This behavior increases the risk of injury and death to the zebra. Why might this type of behavior evolve if it is so clearly a disadvantage to the individualarrow_forwardMany species of animals make alarm calls, which warn others in their group that a predator is approaching. Alarm calls also attract the atten- tion of the predator, making it more likely that the individual making the call will be eaten. Why might natural selection favor the evolution of alarm calls in a species? How might you test that hypothesis?arrow_forwardDo the following two hypothesis supports their graphs? Explain. Figure 1: The hypothesis for novice vs. experienced foraging is that animals who have been foraging for ages should have a greater chance of survival than beginner foragers since they are more skilled and invest less time looking for food. Figure 2: The hypothesis behind the impact of Prey camouflage is that if animals, especially novice foragers, take too much time searching, they are visible to predators for long durations, providing a better chance to attack.arrow_forward
- How would you apply this in a Lamarckian explanation? Tiger Moths (Bertholdia trigona) produce high pitched ultrasonic clicking (at a rate of 4500 clicks/sec) when they hear the echolocation calls of bats (bats eat moths). As a result, the bat's sonar is jammed and the Tiger Moth escapes without being caught, killed, and eaten. Please use your knowledge of Evolution by Natural Selection to explain the process by which this remarkable anti-predator defense evolved in Tiger Moths.

- Suppose Inverness was considering offering a special add-on to its standard Dental insurance. For an additional 1 dollar a month a family could be fully covered for professional teeth whitening, something that normally would cost five thousand dollars a treatment. The whitening procedure would erase any stains that build up over time as a result of drinking too much coffee. Would this benefit create an adverse selection and/or moral hazard problem? If so explain why, and how the benefit could be better designed to address these issues.arrow_forwardWhich of the following statement(s) about adaptations is true? “Adaptation” is another word for “acclimatization.” or They are traits that confer increased fitness in a given environment.arrow_forwardIn the post-industrial forest (dark forest), how did the ratio of light colored moths to dark-colored moths change over time? Question 7 options: The ratio of light colored moths increased relative to the number of dark colored moths. There was no change in the ratio between light and dark-colored moths. The ratio of dark colored moths increased relative to the number of light colored moths.arrow_forward
