Chapter 43, Problem 2CT
Summary Introduction
To explain: The reason why researchers suspect that the ecological factors, not genetic ones, were the most important selective force in Damaraland mole-rat altruism.
Concept introduction: Altruism is a process when an organism behaves in a way that benefits others instead of being harmed or risking oneself. Eusocial animals are the colonial groups that live in multi-generational family groups where the sterile individuals will work for the reproductive success of others. The only way to develop the altruistic behavior is through kin selection.

Among the Great Apes, yet unlike our chimpanzee and bonobo 'cousins', as humans we combine a unique evolutionary blend of different physical and behavioral traits commonly identified with either 'pair-bonding' or 'tournament' species. Which of the following options below inaccurately matches our shared characteristics with each type?
Select one:
a. moderate to high degree of sexual dimorphisms - tournament
b. moderate to highly monogamy in coupled relationships - tournament
c. male mate pickiness - pair bonding
d. high parental investment - pair bonding
e. females selecting mates for parenting skill - pair bonding
f. moderate to high variability in male reproductive success & aggression - tournament
Endler (1980) set up two experiments, one in the greenhouse and one in the field to test the influences of mate choice and predation in determining colorfulness of male guppies.
Identify the roles of mate choice and predation in determining colorfulness of male guppies.
Identify the advantage and shortcomings of the greenhouse experiments.
Identify the advantages and shortcomings of field experiments along the Aripo River.
Identify other factors, especially physical and chemical factors, might influence male color.
Many species of birds have elaborate mating rituals that include bird calls, nest construction, and courtship displays. A researcher is comparing two populations of birds with similar morphology that live in similar niches. Male birds in one population build a nest before attempting to court a female, while males in the other population build the nest in cooperation with the female. Is it likely the researcher will classify these birds as the same species?

- Tests on wild cheetahs have shown that there is low genetic diversity among individuals. Wildlife biologists and conservationists are worried about what this means for the survival of this species. Why is low genetic variability a big problem when it comes to a species survival in a changing habitat?arrow_forwardWhich of the following is an example of a question about mechanism (not function)?

A change in food resources on an island favors finches with medium-sized beaks. Finches with small and large beaks disappear from the island after a few generations. Female flies prefer to mate with males that have longer eyestalks. These eyestalks provide no survival advantage, but longer eyestalks become more common over generations. Male seals compete for territory and access to clusters of female seals. The more aggressive male seals tend to secure the largest territories and clusters.arrow_forward
- Ancestors of the beach mouse mayhave exhibited variations in their coat color. Because of the prevalence of visualpredators, the better-camouflaged (lighter) mice in the beach habitat may havesurvived longer and been able to produce more offspring. Over time, a higher andhigher proportion of individuals in the population would have had the adaptation of lighter fur that acted to camouflage the mouse in the beach habitat.arrow_forwardKin Selection - Ground squirrels will often give a warning call when they see a predator, altering the other ground squirrels to the danger. Calling behavior draws attention to the calling squirrel. This being the case, why would natural selection favor this altruistic behavior? Consider this - female squirrels are 70% more likely to make a warning call than male squirrels. Also consider, male squirrels leave the colony when they reach maturity, while female squirrels stay in the colony they are born in. Explain how natural selection is working here!arrow_forwardWhich of these interactions are examples of sexual selection? *Pick All Green butterflies are less likely to be eaten than yellow butterflies due to their color.

Giraffes are approximately 6’ tall and weigh 150 lbs at birth. b. Wild giraffes begin mating at 6-7 years of age. c.

Giraffes rarely give birth to twins.arrow_forwardOn the Bahamian island of Andros, mosquitofish populations live in various, now-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish that can swim in short, fast bursts; other predator-poor ponds have mosquitofish that can swim continuously for a long time. When placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences. If one builds a canal linking a predator-rich pond to a predator-poor pond, then what type(s) of selection should subsequently be most expected among the mosquitofish in the original predator-rich pond, and what type(s) should be most expected among the mosquitofish in the formerly predator-poor pond? stabilizing selection; directional selection stabilizing selection; stabilizing selection less-intense directional selection; more-intense directional selection less-intense disruptive selection; more-intense…arrow_forward
