Chapter 51, Problem 8TYU
EVOLUTION CONNECTION We often explain our behavior in terms of subjective feelings, motives, or reasons, but evolutionary 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 in love” incompatible with an evolutionary explanation?

What are 4 conditions in which natural selection favors altruistic behaviors in which the individual performs costly actions to benefit others?
The northern red-legged frog, or Rana aurora, is found along the western coast from British Columbia to Northern
California. Their typical breeding season lasts from January to March. The foothill yellow-legged frog, or Rana boylii, is
found along the western coast from northern Oregon to central California. Their typical breeding season lasts from April to
July. What mechanism might keep Rana aurora and Rana boylii from mating?
anatomical isolation
temporal isolation
geographic isolation
behavioral isolation

- How can behaviors be adaptive? Provide an example that includes support from the five tenants of evolution by natural selection: 1) overproduction of offspring, 2) variation in the population, 3) competition for resources, 4) adaptive advantage for some, and 5) reproduction for those who survivearrow_forwardActivity: Factors involved in Natural Selection / Interpreting X-Y graphs The boldness of bass A recent study of largemouth bass, a type of freshwater fish, showed that individual fish have distinct personality types. The researchers looked at a fish's willingness to explore a new environment, which they called boldness. A more bold fish is one that will readily explore when placed in a new setting. Their study considers if boldness may be an adaptive trait, that is, subject to natural selection. The researchers therefore looked at the correlation between parent and offspring boldness scores, as shown in the figure. A. What pattern is illustrated by this figure? What factor(s) necessary for natural selection are shown in this graph? The association between the boldness scores OF Parents & Children is depicted in the image. Offspring boldness score I+ demonstrates the heredity Of audacity, an element required For natural selection 0.5- 0.0- -0.5- -1.0- 0.5 1.0 Parent boldness score…arrow_forwardPlease solvearrow_forward
- Part 1. Neuroscience of social behaviour The data in figure 1 below show the shoaling behaviour of wild-type zebrafish compared to a novel zebrafish mutant. Groups of sixteen fish were placed into a large rectangular tank and their behaviour was recorded for 5 minutes. Tracking software was used to estimate the nearest neighbour distance and inter-individual distance. The bar charts depict the mean and standard deviation (shown as an error bar). ** indicates a statistically significant difference individual differences. Q1. Describe the phenotype of the mutant zebrafish compared to wild-type. I found this question online for revision but i cant find the mark scheme.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_forwardWhich of the following is true about evolutionary psychology? a. Natural selection works differently in humans than other animals. b. It is easy to test evolutionary hypotheses by doing experiments. c.Most social behaviors are genetically determined with little influence by the social environment. d. Evolutionary approaches can generate novel hypotheses about social behavior that can then be tested with experiments.arrow_forward
- Define 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_forwardAssume 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_forwardA breeding pair of birds receives help raising their young from an unrelated male bird. This behavior is termed cooperative breeding and in some ways this seems like an evolutionary paradox since helpers seem to be acting in ways that increase the fitness of others at their own cost. .How might providing this assistance improve the fitness of the unrelated male bird? Increasing the fitness of the unrelated offspring directly increases the unrelated bird's fitness O The cooperative relationship helps the unrelated male survive until he can find a mate and produce offspring of his own Rearing unrelated offspring delays sexual maturity in the helper bird so he has fewer offspring over the course of his life. Because he does not ever produce offspring of his own, the helper bird has a longer and healthier life.arrow_forward
- Please help me and explainarrow_forwardWhich form of conditioning is used most for behavior modification? Why does this form work better? Why would Classical Conditioning help someone in their daily life functioning? Which form of conditioning would you most likely see in a classroom setting? Create your own examples of each form of conditioning. Be sure to include the following information in your answer. In addressing classical conditioning: Identify UCS, UCR, NS, CS, and CR. Discuss any stimulus generalization that you observed. Discuss any extinction and spontaneous that occurred. In addressing operant conditioning: Identify negative and positive reinforcements and punishments. Label the schedule of reinforcement or punishment.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).
