Chapter 39, Problem 10TYU
Summary Introduction
To describe:
The relationship between the two kinds of explanation and explain the behavior such as “falling in love” incompatible with an evolutionary explanation.
Introduction:
The reproductive fitness concept is given by the Darwin. According to the Darwin reproductive fitness concept, nature selects for those individuals that reproduce better and produces higher number of offspring. In those offspring only that will survive who adapt to the environment and survive to the present environment.

What are 4 conditions in which natural selection favors altruistic behaviors in which the individual performs costly actions to benefit others?
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?
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.

- How much of our behavior is determined by our genes versus the environment? Provide two examples of why or why not.What do you think are the pros and cons for an individual if they believe genes determine their behaviors? What are the pros and cons for individuals if they believe nature determines their behaviors? What do you think are the implications for society if we put a lot of weight on nature or nurture?arrow_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.

- 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_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_forwardPlease solvearrow_forward
- A 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_forwardIn the context of the runaway sexual selection hypothesis, what role does female mate choice play in the evolution of exaggerated traits in males? Females ignore males with exaggerated traits in favor of other factors such as resources Females display exaggerated traits themselves to attract males with similar traits Females have no preference for males with exaggerated traits Females actively select mates with these traits, leading to their exaggerated developmentarrow_forwardWhich of the following is LEAST consistent with how behavior tends to evolve? Changes to underlying neural mechanisms, such as neurotransmitter receptors that affect motivation, can result in major changes in behavioral phenotypes Tweaks to the developmental process, such as play or learning, can cause evolutionary divergence in behavior Changes in the properties of sensory receptors can shift preferences and choices Variation in the gene for a given behavior results in population divergence Why are there biases in learning processes? The initial neural structure underlying learning may not allow every possible learned association Some cues are more likely than others to be associated with particular things, which has shaped the evolution of neural networks that represent the world Reducing the range of possible things a brain can learn can be one way to reduce the costs of learning All of the abovearrow_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_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). According to Hamilton’s Rule, if natural selection favors this behavior to help four grandchildren, it should also be favored when the recipients are Group of answer choices eight first cousins All the given answers are correct two siblings four niecesarrow_forwardSexual selection is kind of natural selection in which characteristics related to mating success are the targets of selection. male features are always the key characteristics selected. competition among individuals of the same sex is always involved. infertility is the most common problem. All of the choices are correct.arrow_forward
