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)
_____ adaptive value of successful mating _____ brain circuits _____ hormones _____ natural selection _____ performance of phylogenetically-related species _____ sensory neurons on the legs and tongue _____ sperm competition _____ threats of predation during the performance _____ visual system _____ wings and wing muscles Clarify question: What is the key concept addressed by the question? What type of thinking is required? Gather Content: What do you already know about physiological and evolutionary factors underlying a behavior? What other information is related to the question? Choose Answer: Given what you now know, what information is most likely to produce the correct answer? Reflection 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?
