Male fruit flies perform a complex mating dance that includes following the female, vibrating a wing to produce a species-specific song, and picking up chemosensory cues by tapping with the legs and licking with the tongue. What physiological features are likely important for causing this behavior? (Check all that apply.)A) Adaptive value of successful matingB) Brain circuitsC) HormonesD) Natural selectionE) Performance of phylogenetically-related speciesF) Sensory neurons on the legs and tongueG) Sperm competitionH) Threats of predation during the performanceJ) Visual systemK) Wings and wing muscles
What will be an ideal response?
B, C, F, J, K
Clarify Question
• What is the key concept addressed by the question?
o The question asks about the underlying factors affecting various behaviors in fruit flies.
• What type of thinking is required?
o This is an analyze question. You have to analyze the various factors that might play a role in the mating dance of male fruit flies. Physiological factors are going to allow the fly to perform the dance. Evolutionary factors help to determine the adaptive value of the dance. This is a check-all-that-apply question; all of the choices that are directly involved in performing the behaviors are correct choices.
Gather Content
• What do you already know about physiological and evolutionary factors underlying a behavior? What other information is related to the question?
o In this question, you need to select all of the physiological factors from the choices given. The physiological factors are the parts of the fly that allow it to perform the dance. Evolutionary forces certainly play a role in selecting for certain behaviors, but they are not physiological factors that allow for the performance of the specific behavior.
Choose Answer
• Given what you now know, what information is most likely to produce the correct answer?
o Brain circuits, hormones, sensory neurons, visual system, and wings are all involved in the physiological factors that are involved in the male mating dance.
Reflect on Process
• Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
o Did you get the question right? You had to look over all the choices and pick out all that are physiological factors that influence behavior.
