In some groups of marmosets, juveniles stick around to help their parents raise their young siblings. In doing so, they forego dispersal to a new group. Given this information, and this information only, what can be said of this behavior: O a. The juveniles have made a decision to maximize their inclusive fitness. O b. This scenario supports the Group Augmentation Hypothesis. O c. The juveniles have made a decision that increases their indirect fitness. O d. The juveniles have made a decision that maximizes their direct fitness. O e. This scenario supports the Temporal Variability Hypothesis.

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?
a. Which characteristic found in the prey species is most likely to be advantageous for survival? Why? What environmental factors might influence this? b. Which characteristic was the most successful for each of the predator and the prey populations? What was the selective pressure that allowed this characteristic to be successful? Remember that selective pressures are external factors, either environmental or from a different population. Predator Characteristic: Prey Characteristic: c. For both predator and prey populations, which characteristic was the least successful? What was the selective pressure? Predator Characteristic: Prey Characteristic:
In a particular bird species who live socially, we sometimes see an individual in the social group helping to rear the offspring of its siblings, rather than finding a mate and reproducing itself. Describe the expected relative importance of direct and indirect fitness benefits to the individual helper, explain your answer. Explain how this same helper could improve its fitness by helping raise the offspring of an unrelated couple.
Suppose two species of morning glories are reproductively isolated because in one species the flowers bloom in early April and in the other species they flower in mid-May. This would be an example of _______ isolation, which is a form of _______ isolation. a. habitat; prezygotic b. temporal; prezygotic c. temporal; postzygotic d. behavioral; postzygotic e. habitat; postzygotic
An 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 nieces
To say that a feature is adaptive is unsatisfying unless we have some idea of what it is adaptive for: by what mechanism did it increase fitness? What is its function?
1. Imagine an altruistic behavior where the direct fitness cost to a donor is 6 and the indirect fitness benefit to the recipient is 30. a. Explain why the behavior is likely or unlikely to evolve between cousins. b. Explain why the behavior is likely or unlikely to evolve between full siblings. c. Explain why the behavior is likely or unlikely to evolve between a non-queen female wasp and her brother.
Primates are examples of: a. density-dependent species b. density-independent species c. r-selected species d. K-selected species
In which situation will populations experience gene flow? A)hybridization between two populations of ground beetles B)natural-selection pressures between two populations of dragonflies C)mate competition between two populations of red-legged grasshoppers D)intersecting migration routes between two populations of monarch butterflies
The graph in Figure 3 represents the beak sizes of the offspring of the birds that survived the drought of1977. (The survivors were represented by the black bars in Figure 2, and this graph shows the beak depth distribution of their offspring in 1978.) Explain the observed change in beak characteristics using the following concepts in your answer: competition, survival of the fittest, inheritance.
Darwinian fitness is a measure of a. survival. b. reproductive success. c. heterozygosity of the gene pool. d. polymorphisms in a population.
These two figures show the relationship between the preference of two different oxpecker species for mammal species vs the tick abundance on different mammal species. The researchers controlled for the thickness of mammal hides. The researchers concluded that these relationships support the hypothesis that oxpeckers are mutualistic and not parasites. Select all the answers that might be a reason why they reached this conclusion. Group of answer choices A. These data show their is a positive relationship between oxpecker fitness and the fitness of mammal species. B. These data show that fitness of oxpeckers increases on mammal species with higher abundance of ticks C. The researchers hypothesized that if oxpeckers are parasitic and not mutualistic, they would expect that there would be no relationship between the preference of oxpeckers for a mammal species and the abundance of ticks on those species. These graphs show a positive relationship between those variables…
