Chapter 51.4, Problem 3CC
Summary Introduction
To propose a hypothesis: To check the altruistic behavior in a person by the Hamilton rule if that person has passed the reproductive age.
Concept introduction:
“Hamilton rule” is applied to analyze the amount of the fitness in an individual by observing the altruistic behavior in an individual. It analyzes the potential of a sibling male or female to reproduce and give rise to the progenies. It was proposed by William Hamilton, a British geneticist.

Thinking Critically
In what ways can members of the same population compete with one another? How might members of different populations compete? Contrast the results of these kinds of competition.

- Need help Multiple choice Fewer than 3% of animals engage in direct care of their offspring. When might the benefits of parental care outweigh the costs? Choose the correct option and Explain why you choose that answer. a) All of the options. b) Species that feed on resources with high foraging effort (e.g., smaller insect prey versus larger insect prey). c) Species with highly immature young, for instance those with large brains that have long learning periods. d) Species with limited breeding opportunities.arrow_forwardTopic: Sexual Selection 1. Describe each factor in mate selection a) Courtship Rituals b) Control of Valuable Resources c) Gifts d) Good Looksarrow_forwardFitness and Selection: Rodent tails A researcher is studying a rodent species with a lot of variability in tail length. Individuals may have short tails, medium tails, or long tails. The researcher has noticed that a new invasive predator, which catches prey by their tails as they try to escape, seems to catch individuals with long tails more often than those with short tails. Based on a small field trial, the relative fitness of long-tailed individuals seems to be 0.6 compared to short-tailed ones (1.0), with medium tails in-between (0.8). Use the Examples tab to predict the outcome after selection for the rodent in regions with the invasive predator. What describes the population after 100 generations of selection? Choose all that apply. A-Short Tailed individuals are the most common phenotype. B-Short Tailed individuals are the only phenotype. C-This is an example of disruptive selection. D- The long tailed phenotype is no longer present E-This is an example of directional…arrow_forward

The benefit of fighting for a territory is 12 reproductive units, and the cost is 8 reproductive units. What is your benefit if you play hawk and your opponent plays dove? Using Hawk Dove Game Theory https://www.youtube.com/watch?v=lshGV-qxJmIarrow_forwardS uppose that you expect a 2:1 male: female sex ratio in a certain insect population. You collect 90 insects at random of which 70 are males and 20 are females. What is the expected number of males under your null hypothesis?arrow_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
- EVOLUTION CONNECTION We often explain our behaviorin terms of subjective feelings, motives, or reasons, butevolutionary explanations are based on reproductive fitness.Discuss the relationship between the two kinds of explanation.For instance, is an explanation for behavior such as “falling inlove” incompatible with an evolutionary explanation?arrow_forwardEvolution connection we often explain our behavior in terms of subjective feelings, motives, or reasons, but evolutionary explanations are based on reproductive fitness. what is the relationship between the two kinds of explanation? for instance, is a human explanation for behavior, such as “falling in love,” incompatible with an evolutionary explanation?arrow_forwardAccording 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_forward

(2011) found that in the purple-crowned fairy-wren, most subordinate helpers at the nest feed full siblings or half siblings, but some helpers are unrelated to the nestlings they assist. What Darwinian puzzle is created by these findings, and how might you solve the puzzle by using inclusive fitness theory? What predictions follow from the explanation(s) that you propose?arrow_forwardDo you believe that humans (whether consciously or unconsciously) use natural selection when choosing a mate?
