Chapter 36, Problem 7WIO
Summary Introduction
To determine:
The types of behaviors that are favored by natural selection in cuckoo and cowbirds and in the adoptive parents.
Concept introduction:
The process by which an organism that is better adopted according to the environment is liable and tend to live and can produce their offspring’s. This is the statement of natural selection theory. This theory was given by Charles Darwin. In the present days it is considered to be the main reason for the evolution.

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 of these interactions are examples of sexual selection? Select all that apply.
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.
Robins typically lay four eggs. Four eggs allow the offspring to be well fed, whereas larger clutches may result in malnourished chicks that have a lower chance of survival. Fewer than four eggs per clutch may result in no surviving offspring if the eggs are preyed upon. Which type of pattern of natural selection MOST LIKELY acts to keep four eggs the most common clutch size?

- European cuckoos and American cowbirds are “brood parasites” that laytheir eggs in the nests of other birds. The chicks are generally raised by“adoptive parents” whose own chicks receive less food and often arekilled by the larger intruders.

It also uses this sucker to scrape food off surfaces. Which of the following statements would be TRUE if we were to call the sucker an adaptation for climbing? The sucker evolved originally under selection for its feeding function and was later coopted for climbing. The sucker evolved originally under selection for its climbing function and was later coopted for feeding. The sucker evolved originally due to drift and was later coopted for feeding.arrow_forward
- Assume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.arrow_forwardWhy might natural selection act more strongly on traits that improve reproductive success early in life rather than later in life?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_forward
- 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.arrow_forwardMonarch butterflies and viceroy butterflies are both found in the United States and parts of Canada and Mexico. Monarch butterflies have a particular orange and black wing pattern and are toxic. Viceroy butterflies are non-toxic but have a very similar wing pattern to the monarch. Scientists have observed that attempted predation of viceroy butterflies is lower in regions that are also inhabited by monarch butterflies. Why would natural selection select for a non-poisonous butterfly with the same markings as a poisonous butterfly?arrow_forwardIf natural selection has no foresight,how can it explain features that seem to prepare organisms for future events? For example, deciduous trees at high latitudes drop their leaves before winter arrives, male birds establish territories before females arrive in the spring, and animals such as squirrels and jays store food as winter approaches.arrow_forward

Is the presence of competitors a selective force?arrow_forwardSatellite and attached male horseshoe crabs do not have the same reproductive success. Why hasn’t sexual selection eliminated the low-payoff satellite option if males exercising this option do not leave as many descendants as attached males do? Please don't write from any online source.arrow_forwardAn individual bird may behave apparently altruistically in a way that decreases its own fitness (by cost C) yet increases the fitness of another individual or set of individuals (by benefit B each).
