Summary Introduction
Introduction: Altruism is an unselfish behavior that increases the fitness of other animals on the cost of fitness of the altruist. In other words, it is a behavior in which an animal helps other animals without getting any benefits. It can be seen in many animals such as honey bees, ground squirrels, mole rats and others.

Which of the following is true of innate behaviors that are described as instincts? A. Instincts aren’t governed by genetics, while innate behaviors are, B. Instincts are governed by genetics, while innate behaviors are not, C. Instincts are sudden, situational behaviors, D. Instincts are complex series of innate behaviors
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
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?

- Why nature keep optimizing behavioral traits of its creatures?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_forwardConsider the following argument: Altruistic behavior in groups of related individuals is most likely driven by kin selection since related individuals would share DNA. Which of the following pieces of evidence would be most likely to weaken this argument? Data showing that only distantly related individuals are most likely to perform altruistic behaviors in order to protect each other Data showing that food gifts are given more common among family members than between unrelated individuals in a group Data showing that individuals that share a higher percentage of DNA in a group tend to show the most altruistic behavior between themselves Data showing that the more frequent an allele of a gene occurs in a population, the more likely that population performs altruistic behaviorsarrow_forward
- How does group selection theory explain the altruistic behavior of animals and why is this explanation problematic for advocates of inclusive fitness theory?arrow_forwardThe field of behavioral ecology asks which question?a. Is behavior hereditary?b. Is behavior adaptive?c. Is behavior modified by experience?d. Is behavior developmentally determined?arrow_forwardCan Kin selection explain eusocialty?arrow_forward
- 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?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_forwardHow might predators and prey both evolve phenotypically plastic strategies to improve their fitness?arrow_forward
- Sexual selection tends to cause bigger size,more elaborate weaponry, or brighter colors in males. Is this an example of stabilizing,directional, or disruptive selection?arrow_forwardWhich ability to learn will evolve in a population of sticklebacks living in predator-rich environment and under which natural selection pressure?arrow_forwardWhich of these interactions are examples of sexual selection? Select all that apply. - Female flies prefer to mate with males that have longer eyestalks. These eyestalks provide no survival advantage, but longer eyestalks become more common over generations. -Male seals compete for territory and access to clusters of female seals. The more aggressive male seals tend to secure the largest territories and clusters. -A change in food resources on an island favors finches with medium-sized beaks. Finches with small and large beaks disappear from the island after a few generations. -Green butterflies are less likely to be eaten than yellow butterflies due to their color. Green butterflies become more numerous than yellow butterflies in the population.arrow_forward
