Students have asked these similar questions
Behavior 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) altruism
How would self-sacrifice of male redback spiders be an adaptive behaviour?
Select one:
a.
When males meet a female and self-sacrifice, it activates enzymes that make
his sperm more fit and able to fertilize more eggs.
b. Males are able to mate with one female, then mate with another female
nearby, before being devoured by the first female.
C.
Males only use self-sacrificing behaviour once they have mated with several
females and have exhausted their sperm supplies.
d. The chance of a male meeting more than one female is quite low; self-sacrifice
maximizes mating time with and sperm transfer to any female the male finds.
Which of the following is an example of a question about mechanism (not function)?
A. What stimuli triggers a mother bird to feed her nestling?
B. How does parental care benefit the mother's inclusive fitness?
C. Why do some species have parental care but not others?
D. Do mother birds get better at caring for their offspring over time?

- Identify whether each of the following scenarios is most likely to result in stabilizing, disruptive, or directional selection a) Beetles that emerge from hibernation too early are more likely to killed by frost, those that emerge too late will miss the chance to mate [Select ] b) Frogs with mating calls that are between 400 and 600 chirps per minute attract more mates than frogs with calls that are lower than 400 chirps per minute or greater than 600 chirps per minute [ Select ] c) Plants with the largest leaves are better able to gather sunlight in the rainforest [ Select ] d) Giraffes with longer necks can reach more leaves, but they have a harder time pumping blood from their heart up to their brain [Select] e) Mice with the lighter fur are better camouflaged from predators than mice with darker fur V [ Select ] stabilizing selection disruptive selection directional selectionarrow_forwardIn the eclectus parrot (Eclectus roratus), mothers sometimes take parental favoritism to extreme lengths by killing their sons, but never their daughters (Heinsohn et al. 2011). Sex-specific infanticide occurs more often at nests that can be flooded during the rainy season. Sons spend longer in the nest than daughters. Link this factor to why it might be adaptive for a parent parrot to kill a son in a vulnerable nest occupied by offspring of both sexes. Don't write from any online source..arrow_forwardHow does a defense mechanism (behavioural, cryptic colouration, protective colouration, mimicry) affect predation and competition? a) Provide an example of a defense mechanism that you have not encountered in the course or in the online assignments. Include an image depicting the defence mechanism, describe the defence mechanism and cite your sources. b) Hypothesize how this defence mechanism may have evolved over time due to pressure from predation and/or competition.arrow_forward
- Territoriality behaviors actually decrease competition between members of the same species. Explain why this is the case, and therefore how territoriality is favored by natural selection.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_forwardFemale mimicry by males occurs in many species. For example, in the Broadley’s flat lizard (Platysaurus broadleyi), some males have the brown coloration of females while others are far more colorful (Whiting et al. 2009). Female mimics do secure some matings in the territories of their larger, more colorful rivals. Why are the bigger males (and those of the marine isopod Paracerceis sculpta) ever fooled into tolerating a female mimic? Why do female mimics occur in any species if the mating success of these individuals is lower than that of the bigger territorial males? Don't write from any online source..arrow_forward
- Think about how we organized the mechanisms of sexual selection (mate competition vs. mate choice; resource-based choice vs. non-resource-based choice, etc.). Based on this organization, choose the pair of examples from the list below that are most closely matched in terms of mechanisms of sexual selection. Male red deer engage in physical contests to determine who mates with a female. Male mouse lemurs engage in scramble competition for female mates. Peahen (female) chooses to mate with a peacock that has large eyespots in the tail feathers of his magnificent display.
