47. 最常见的引述别人观点的词汇
Much of the research in sexual selection in the last two decades has examined how a female’s preference that does not influence her immediate reproductive success can still evolve if it is genetically correlated with another character under direct selection.(不要每次写到研究时总用study，可以用些其它的词汇，比如examine，work。)
Two hypotheses for female preference evolution—runaway sexual selection and good genes selection—state that preferences evolve indirectly because they are genetically correlated with male traits that are under direct selection; that is, the preferences themselves are not under direct selection.(在引述别人的观点时，如果不能完全同意，使用state 比show更加中立些。)
Studies of receiver biases suggest that such analogies might not be broadly applicable.(suggest,又一种较为客观的引述观点的表达方法。免费下载：18款超实用软件轻松搞科研)
Burley argued that the preference for red beaks is adaptive because it indicates male health, and this preference is then transferred to leg-band color.(argue,引用别人观点的又一表述。)
According to the anti-monotony hypothesis, habituation plays an important role in the evolution of complex vocalizations in songbirds: Increased song complexity reduces habituation of neighboring males and courting females.(根据…)
Previous studies of acoustic and bioluminescent interactions had emphasized potential advantages to group-signaling organization, such as minimizing predation, preserving species-specific signal characters, or increasing the attractiveness of the group.(带有小小的强调)
