A cage containing male mosquitoes has a small earphone placed on top, through which the sound of a female mosquito is played. All the males immediately fly to the earphone and go through all of the steps of copulation. What is the best explanation for this behavior?

A.Copulation is a fixed action pattern, and the female flight sound is a sign stimulus that initiates it.

C.Through classical conditioning, the male mosquitoes have associated the inappropriate stimulus from the earphone with the normal response of copulation.

D.The reproductive drive is so strong that when males are deprived of females, they will attempt to mate with anything that has even the slightest female characteristic.

During a field trip, an instructor touched a moth resting on a tree trunk. The moth raised its forewings to reveal large eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answered that sensory receptors had fired and triggered a neuronal reflex culminating in the contraction of certain muscles. A second student responded that the behavior might frighten predators. Which statement best describes these explanations?

A.The first explanation refers to proximate causation, whereas the second refers to ultimate causation.

B.The first explanation is correct, but the second is incorrect.

C.The first explanation is testable as a scientific hypothesis, whereas the second is not.

D.Both explanations are reasonable and simply represent a difference of opinion.

A

Behaviors are diverse and important for survival and reproduction. Some behaviors are learned, such as the species-specific song of a yellow warbler which is different from the song of a blue-winged warbler. Other behaviors are innate, such as a female cat in heat urinating more often and in many places to attract a mate or honeybees do a "dance" that indicates the distance and direction of a food source when they return to their hive. Which of the following statements supports the idea that behaviors are important in survival and therefore affect natural selection?

A.Learned behaviors may not necessarily increase fitness. Baby warblers can learn the song of another species.

B.Innate behaviors are the result of selection for individual survival and reproductive success.

C.Both innate and learned behaviors are entirely based on genes inherited from parents.

D.All behaviors are survival mechanisms that increase reproductive fitness by increasing mutation rates.

B

In testing a hypothesis that "territorial defense in European robins is a fixed action pattern that is released by the sight of orange feathers," researchers found that robins defended their territory by attacking anything that was of similar size and had an orange patch. What experiment would you perform next to determine that the color initiated the defense response?

A.Repeat the experiment by using a model of a robin that had an orange patch that was twice the size of a normal patch.

B.Repeat the experiment by using a model of a robin that was twice the size of a normal robin but with a small orange patch.

C.Repeat the experiment by removing the patch completely.

D.Repeat the experiment using a blue patch instead of an orange patch.

D

You observe a large black bird with a shiny black crest engaging in courtship behavior with a little brown bird. It would be reasonable to hypothesize that this is an example of _____.

A.monogamy

B.mating with the wrong species

C.polygyny

D.polygamy

E.polyandry

D

You discover a rare new bird species, but you are unable to observe its mating behavior. You see that the male is large and ornamental compared with the female. On this basis, you can probably conclude that the species is _____.

C.agonistic

D.polyandrous

Fred and Joe, two unrelated, mature male gorillas, encounter one another. Fred is courting a female. Fred grunts as Joe comes near. As Joe continues to advance, Fred begins drumming (pounding his chest) and bares his teeth. Joe then rolls on the ground on his back, gets up, and quickly leaves. This behavioral pattern is repeated several times during the mating season. Choose the most specific behavior described by this example.

A.territorial behavior

B.learned behavior

C.agonistic behavior

D.fixed action pattern

C.Females produce more eggs more quickly when exposed to breeding males.

D.All non-isolated females do just as well as isolated females.

C

Which of the following is not required for a behavioral trait to evolve by natural selection?

B.An individual's genotype influences its behavioral phenotype.

C.The behavior varies among individuals.

B & C

Graylag goslings imprint on a nearby object that moves away from them during a sensitive period in the first few hours after they hatch, and follow the object steadfastly from that time on. What is the adaptive value of this behavior?

B.This behavior is genetic.

C.This behavior is likely to increase gosling survival.

C
