性展示是一些最戏剧性和各种各样的行为，已被记录在案。这种行为的阐述往往依赖于现有形态的修改。为了了解如何显示阐述出现，我们分析了三种小鼠的喉部解剖，不同的存在和复杂性，他们的声音显示。小鼠和大鼠有一个专门的喉部，使它们能够产生低频的“可听”声音，可能使用声带振动，以及被认为能够产生高频声音的独特机制，如声带振动和喉内哨声。这些机制依赖于喉内的不同结构。使用组织学，我们的特点喉解剖阿尔斯顿的唱歌小鼠（Scotinomys teguina），北方侏儒小鼠（Baiomys taylori），和实验室小鼠（小家鼠），产生不同类型的发声。我们发现了所有物种的声带膜的证据，以及声带和腹袋大小的物种差异。在这三个物种，这是不知道使用声膜振动的声膜的存在下，表明这种结构可能是普遍存在于muroid啮齿类动物。唱歌和侏儒小鼠的腹侧袋扩大表明这些小鼠可能使用喉内口哨来产生广告歌曲，并且腹侧袋扩大可能使频率低于实验室小鼠口哨产生的声音。啮齿类动物喉部解剖结构的变化符合陆生脊椎动物的一个更大的模式，其中发声膜和囊或气囊的发育和修饰是发声多样化的常见机制。了解相关器官功能解剖学的变化是了解形态变化如何实现新颖显示的第一步。
Sexual displays are some of the most dramatic and varied behaviors that have been documented. The elaboration of such behaviors often relies on the modification of existing morphology. To understand how display elaboration arises, we analyzed the laryngeal anatomy of three species of mice that vary in the presence and complexity of their vocal displays. Mice and rats have a specialized larynx that enables them to produce both low-frequency “audible” sounds, perhaps using vocal fold vibration, as well as distinct mechanisms that are thought to enable higher frequency sounds, such as vocal membrane vibration and intralaryngeal whistles. These mechanisms rely on different structures within the larynx. Using histology, we characterized laryngeal anatomy in Alston’s singing mouse (Scotinomys teguina), the northern pygmy mouse (Baiomys taylori), and the laboratory mouse (Mus musculus), which produce different types of vocalizations. We found evidence of a vocal membrane in all species, as well as species differences in vocal fold and ventral pouch size. Presence of a vocal membrane in these three species, which are not known to use vocal membrane vibration, suggests that this structure may be widespread among muroid rodents. An expanded ventral pouch in singing and pygmy mice suggests these mice may use an intralaryngeal whistle to produce their advertisement songs, and that an expanded ventral pouch may enable lower frequencies than laboratory mouse whistle-produced sounds. Variation in the laryngeal anatomy of rodents fits into a larger pattern across terrestrial vertebrates, where the development and modification of vocal membranes and pouches, or air sacs, are common mechanisms by which vocalizations diversify. Understanding variation in the functional anatomy of relevant organs is the first step to understanding how morphological changes enable novel displays.
