The unstated assumption is that these are all honest signals —that is, their frequency or the quality of their production is directly related to the singer's underlying physiology and cannot be modified to give a false impression of his fitness.

未被说明的假定是这些都是可靠的信号，即它们发生行为的频率或特质与这只蹄兔的根本生理条件有直接关系，这不会因为要给它的合适伴侣一个错误的看法而改变。

They discovered, as they report in Behavioral Ecology and Sociobiology, that male hyraxes are doing far more than just repetitively communicating that they are ready to mate.

然后，她和Geffen博士分析资料以寻找一个蹄兔的唱歌方式和其解剖学和行为学细节的相互关系。。

Hyraxes and some extinct animals.

蹄兔和一些绝迹的动物种类。

They knew that hyraxes (small, furry animals that are the closest living relatives of elephants) sing to one another, and they suspected that the songs have something to do with courtship, since they happen less frequently once the animals have mated.

蹄兔是身材矮小的毛皮动物，是现存的与大象最近的亲属。

Songs conclude with a series of snorts that are connected to the singer's levels of certain male hormones.

以一系列喷鼻声结束无疑与这只蹄兔的雄性激素有关。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
