According to Hamilton’s rule,(A) natural selection does not favor altruistic behavior thatcauses the death of the altruist.(B) natural selection favors altruistic acts when the resultingbenefit to the recipient, corrected for relatedness, exceedsthe cost to the altruist.(C) natural selection is more likely to favor altruistic behaviorthat benefits an offspring than altruistic behavior thatbenefits a sibling.(D) the effects of kin selection are larger than the effects ofdirect natural selection on individuals.
Nursing bees take care of the queen and newly hatched bees. However, nursing bees themselves do not reproduce. How could natural selection act upon such behavior?
Because this behavior does not directly benefit the nursing bee itself, it is not favored by natural selection.
Because this behavior increases the number of surviving offspring that share genes with the nursing bee, it is favored by natural selection.
Because this behavior selectively decreases the number of offspring harboring non-similar genes with the nursing bee, it is favored by natural selection.
Because this behavior does not increase the number of surviving offspring that are identical in genes with the nursing bee, it is not favored by natural selection.
Which research question does not refer to proximate causes of behavior?
a.) How do rhesus macaques find their food?
b.) how do pigeons that are experimentally displaced find their way back to their home loft?
c.) How does dispersal affect the survival of Belding's ground squirrels?
d.) Do mother goats learn the odor of their offspring?
e.) How do hummingbirds “know” when it is time to return to their overwintering grounds?

- You are wandering in the Amazon rainforest, when you hear the loud call of an animal. You walk in the direction of the sound, and discover that it is coming from an adorable species of frog. a) What type of adaptation is being displayed by this species of frog? b) Describe how selection could work FOR and AGAINST this adaptation.arrow_forwardDefine natural selection using the 5 points below to explain its role in understanding primate behavior. (1) there is variation among individuals; (2) some of that variation is heritable; (3) there is always competition between individuals for resources; (4) some variants outcompete other variants and leave more offspring; (5) to the extent that the parent's traits are heritable, then a larger portion of the next generation will reflect those traits.arrow_forwardIn the eclectus parrot (Eclectus roratus), mothers sometimes take parental favoritism to extreme lengths by killing their sons, but never their daughters (Heinsohn et al. 2011). Sex-specific infanticide occurs more often at nests that can be flooded during the rainy season. Sons spend longer in the nest than daughters. Link this factor to why it might be adaptive for a parent parrot to kill a son in a vulnerable nest occupied by offspring of both sexes. Don't write from any online source..arrow_forward
- You are a wildlife biologist researching black rhinos. During your time in Africa, you have observed two particular traits that allow some black rhinos to be better adapted to their environment. The first trait is an extra-long prehensile lip that enables the rhino to have more efficient browsing capabilities than rhinos with the usual size prehensile lip. Second, some of the rhinos in the study have extra-large ears that allow them to hear a potential predator earlier than rhinos with normal size ears. If you could breed black rhinos that have both of these good traits (an extra-long prehensile lip (P) and bigger ears (E), it wouldincrease their chance for survival in the wild. You have chosen the following two rhinos to enter into a breeding program for the two desired phenotypic traits. It has been determined (based on your previous research) that both the desired traits are homozygous recessive. Parent 1: Heterozygous dominant for prehensile lip trait. Heterozygous for the longer…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_forwardThe digger bee’s “postcopulatory courtship” consists of elaborate tactile stimulation that the male provides his partner after she has accepted his sperm. Why is this behavior a Darwinian puzzle, and what might its adaptive value be?arrow_forward
- Although many chimpanzees live in environments with oilpalm nuts, members of only a few populations use stones tocrack open the nuts. The likely explanation is that(A) the behavioral difference is caused by genetic differencesbetween populations.(B) members of different populations have different nutritionalrequirements.(C) the cultural tradition of using stones to crack nuts hasarisen in only some populations.(D) members of different populations differ in learning abilityarrow_forwardWhich of the following is true of innate behaviors that are described as instincts? A. Instincts aren’t governed by genetics, while innate behaviors are, B. Instincts are governed by genetics, while innate behaviors are not, C. Instincts are sudden, situational behaviors, D. Instincts are complex series of innate behaviorsarrow_forwardIntrasexual selection involves competition among one sex (typically males) for mating access to the other sex. Intersexual selection involves mate choice in which individuals from one sex (typically females) choose their mates from among individuals of the other sex. Imagine a group of males that is engaged in agonistic behavior, from which Male A emerges triumphant. Now imagine a female that is assessing all of the males that were involved in the fights, and chooses Male A. Explain why this situation shows how intrasexual and intersexual selection pressures are likely both at play in the trait selection.arrow_forward
