Q2 1 Niko Tinbergen Would Have Argued That 1 Point O It Is Most Important To Study The Development Of Behavior Because 1 (147.81 KiB) Viewed 11 times

Q2.1 Niko Tinbergen would have argued that: 1 Point O It is most important to study the development of behavior because developmental processes determine what behaviors an individual animal will be capable of as an adult. O It is most important to study the mechanisms by which behaviors are produced because these mechanisms determine what an individual animal will actually do from moment to moment. O It is most important to study the evolutionary history of behavior because evolutionary history can explain whether a particular animal is likely to have the capacity to perform a particular behavior or not. O It is most important to study the fitness consequences of behavior because fitness consequences determine whether a particular behavioral trait will be passed on to subsequent generations or not O We should study all four of the above aspects of behavior because all four are necessary to form a complete understanding of the behavior in question.

Q2.2 Which of the following is the most accurate statement about the song nucleus HVC? 1 Point O It plays roles both in motor production and in learning of song. O It plays a role only in motor production of song. O It plays a role only in the learning of song. O The "neural template" for song development is contained entirely within the HVC. O The HVC plays a completely different role in song development for males than it does for females. Q2.3 Which of the following is a reasonable possible Proximate Developmental explanation of the geographic distribution of different song types of Great Tits living in Europe? 1 Point Great Tits living in dense forests sing songs that contain predominantly low-pitched notes because those songs transmit better than ones with higher-frequency notes in that environment and therefore are more likely to attract mates and repel competitors. Great Tits living in open woodlands (with many fewer trees than dense forests have) sing songs that include many high-pitched notes because the sparse vegetation in these habitats allows effective transmission of high-pitched notes so these songs are more effective at attracting mates and repelling competitors. Great Tits living in dense forests learn predominantly low-pitched song phrases because they hear more of those than high-pitched phrases while they are growing up. O All of the above.

Q2.4 Which of the following is a complete and accurate statement regarding sound production by the songbird syrinx? 1 Point O One side of the syrinx must be completely occluded (closed off) in order for the other side to produce a sound during exhalation. O If one side of the syrinx is partially occluded (air flow is restricted), then that side will produce a sound during exhalation. O If one side of the syrinx is partially occluded, then it may produce a sound during exhalation as long as the other side is either partially or completely occluded. All of the above are both complete and accurate. O None of the above are both complete and accurate.
