Textbook Question
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?

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 survive

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.

- 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_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_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
- Please help me and explainarrow_forwardPlease help me with this problemarrow_forwardClarify the difference between claiming that, a) some behaviours are genetically determined, versus b) some differences among individuals in behavioural phenotype are genetically determined. Are both claims valid in some circumstances? Use any suitable example you know about to justify your answer.arrow_forward
- When discussing natural selection and behaviour, we often say that members of a species have certain behavioural traits because those traits are adaptive, in the sense that they increase inclusive fitness relative to alternative forms of those traits that have existed in the past. Instead of emphasizing the adaptiveness of behavioural traits, some biologists describe natural selection as a process that operates on nervous system traits, increasing the prevalence within a population of particular patterns of neural circuitry and neurobiological mechanisms. As an alternative to emphasizing either the behaviour or the nervous system, some biologists describe natural selection as a process that operates on genes; according to this perspective, certain forms of certain genes (ie., particular alleles) increase in prevalence within a population relative to alternative forms of those genes. Which, if any, of these three perspectives on natural selection and behaviour do you think is the most…arrow_forwardEcology regarding sexual selection: In zebra finch females prefer males who have a larger yellow cheek patch. Researchers investigating this preference think that females must benefit from choosing males with large cheek patches. Provide three hypotheses regarding the direct, or indirect benefits, she might receive.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
- Natural and sexual selection both lead to evolution, but these processes can work against each other. Differentiate between these two forms of selection and give an example of a situation where natural selection reduces mate choice and sexual selection reduces survival.arrow_forwardThe good genes model of sexual selection is a popular hypothesis for mate choice. What is an underlying flaw with the hypothesis that must be explained?arrow_forwardYou are raising a stock of Drosophila flies in which you have clipped off the wings of each individual. Assume that this treatment does not disrupt their mating success (it would). If you clip off the wings in each subsequent generation, what would you expect to observe in the 50th generation? Why? This is an example of whose ideas in evolution?arrow_forward
