Question
Chapter 52.7, Problem 1C
Summary Introduction
To explain: In what way the kin selection explains the altruistic behavior.
Introduction: Altruism is a process of completing the necessities of another animal. There is no profit gained by the helper by any means at the instance of time. The signals produced by the helper for the benefit of the other animal can be about danger, food, shelter, or anything related to the requirement of the animal.

Evolutionary biology
What are 4 conditions in which natural selection favors altruistic behaviors in which the individual performs costly actions to benefit others?
Earlier explanations of altruistic behavior as a form of group selec-tion have been supplanted by Hamilton’s hypothesis of kin selection. What distinguishes kin selection and how does it accord with the no-tion of inclusive fitness, the relative number of an individual’s alleles that pass to the next generation?
How does group selection theory explain the altruistic behavior of animals and why is this explanation problematic for advocates of inclusive fitness theory?

- Hamilton's Rule describes the relationship between cost and relationship in the evolution of altruistic behavior. Which of the following do not support Hamilton's rule: In colonies of Naked Mole Rates, only one female is reproductive. Cattle egrets sometimes kill their siblings. Wood mouse sperm will sacrifice themselves to assist a "sibling" sperm to fertilize an egg. O A Prairie Dog trills in response to an oncoming predator and is more likely to be eaten because it exhibits this behavior.arrow_forwardWhat is individual variation? Provide specific types of individual variation of behaviorarrow_forwardUsing the concept of inclusive fitness (and kin selection), explain how altruistic behavior (e.g. where an individual protects for another, even at their own expense) can evolve by natural selection? Make sure to explain what inclusive fitness is. (remember the concentric circles on the slide)arrow_forward
- Which piece of evidence best supports the hypothesis that the evolution of altruistic behavior is driven by kin selection? A hippo is observed saving an antelope from an attack by an alligator. A cuckoo bird hides its own eggs in the nest of another bird species. A meerkat protects the offspring of its sister from an attack by hawks. A male gorilla helps protect his offspring from an attack by a tiger.arrow_forwardWhich 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 do hummingbirds “know” when it is time to return to their overwintering grounds?arrow_forwardWhich piece of evidence would best support the argument for kin selection as a mechanism for the evolution of altruistic behavior? an antelope gets separated from the herd and killed by predators a penguin protects its chick from seagulls a clown fish helps clean parasites off of a sea anemone a hippo stops a crocodile from eating an antelopearrow_forward
- You document altruism in an animal species that you are studying: female zebras running at the back of the group, closest to the pursuing predator, as the group runs to escape a predator. Both kin selection and reciprocal altruism can explain this behavior. What piece of evidence would support the hypothesis that it's kin selection?arrow_forward why do females have a greater disadvantage compared to males concerning sexual reproduction? How has this difference between the sex shape sexual selection in general? Choose one form of communication and explain how it is used by competing sex is attracting a mate. arrow_forwardBehavior that appears to have no payoff—that is, an individual appears to act to benefit others rather than itself—is known as (a) mutualism (b) helping behavior (c) reciprocal altruism (d) inclusive fitness (e) altruismarrow_forward
