Which answer is consistent with evolutionary biology in the following problem?
The evolution of suicidal behavior of lemmings (a rodent from the Arctic Circle) as a response to rapid
population increase is not possible because:
-it would not permanently keep population size down
-it would be costly for the individuals exhibiting the behavior, but beneficial to those who do not show it
-it would be too slow to have an effect on the cyclical population growth of lemmings
-it works only when a large proportion of the population shows the same behavior - (ANSWER)it would
be costly for the individuals exhibiting the behavior, but beneficial to those who do not
show it
What is correct in the context of the fitness definition?
Successful mating is generally sufficient to ensure fitness
The production of viable offspring is generally a sufficient predictor of fitness
Fitness is determined by the production of healthy and competitive offspring that can reproduce
once they reach adulthood
Everything applies - (ANSWER)Fitness is determined by the production of healthy and competitive
offspring that can reproduce
once they reach adulthood
In a species of bird, males show red plumage coloration. Researchers try to answer the question, how do
the males display the red coloration? They found that carotenoids present in their food are used by the
body to produce red coloration in the feathers.
At what level of analysis did the researchers investigate this question?
-proximate relating to ontogeny or genetic-developmental mechanisms

-proximate relating to "machinery" or physiology of the animal
-ultimate relating to "function" or the adaptive value of this signal
-ultimate relating to the evolutionary history of this trait - (ANSWER)proximate relating to "machinery"
or physiology of the animal
Song dialects of different populations in white-crowned sparrows are based on?
i. Genetic differences between populations
ii. Learning of population-specific dialects in juveniles
iii. Presence of other songbirds in the area with different song types
Only i. is correct
Only ii. is correct
Only iii. is correct
Only i. and iii. are correct
Only ii. and iii. are correct
All are correct - (ANSWER)Only ii. is correct
In many species, high testosterone levels are associated with increased aggression and dominance that
often leads to increased reproductive success. What would you expect for blood testosterone levels?
Given the benefits of high testosterone levels, it pays off to maintain high levels of testosterone
throughout the year even during times without mating or dominance interactions
Testosterone levels should always be constantly high during times of potential aggressive
encounters irrespective of their actual occurrence
Given the costly effects of high testosterone levels, they should be adjusted to current needs
High testosterone levels are generally not adaptive given the costs involved - (ANSWER)Given the costly
effects of high testosterone levels, they should be adjusted to current needs
