性选择的一个标志是进化出复杂的雄性性信号。然而,动物的生理学如何改变以支持新的或修改的信号是一个基本上没有答案的问题。雄激素在调节雄性生殖行为中是重要的,因此,对特定信号的选择可能会驱动其产生背后的神经运动系统中雄激素敏感性增加的进化。对无尾两栖类性信号的神经内分泌机制的研究为支持这一观点提供了证据。在此,我们重点介绍两个这样的案例:首先,对Xenopusfrogs的大量研究表明,喉神经和肌肉中的性二态雄激素受体(AR)表达是性二态发声行为的基础,其次,我们自己的研究表明,后肢信号的最新进化(称为“足旗”)在Staurois parvusis伴随着显着增加的雄激素敏感性的大腿肌肉控制肢体运动。总之,这些例子说明,进化修饰或增益的性信号与一种新的模式的AR表达的组织中,支持it.We表明,这种共同进化的AR表达和性别特异性或物种特异性的信号传导行为存在于脊椎动物。
A hallmark of sexual selection is the evolution of elaborate male sexual signals. Yet, how the physiology of an animal changes to support a new or modified signal is a question that has remained largely unanswered. Androgens are important in regulating male reproductive behavior, therefore, selection for particular signals may drive the evolution of increased androgenic sensitivity in the neuro-motor systems underlying their production. Studies of the neuroendocrine mechanisms of anuran sexual signaling provide evidence to support this idea. Here, we highlight two such cases: first, a large body of work inXenopusfrogs demonstrates that sexually dimorphic androgen receptor (AR) expression in the laryngeal nerves and muscles underlies sexually dimorphic vocal behavior, and second, our own work showing that the recent evolution of a hind limb signal (known as the “foot flag”) inStaurois parvusis accompanied by a dramatic increase in androgenic sensitivity of the thigh muscles that control limb movement. Together, these examples illustrate that the evolutionary modification or gain of a sexual signal is linked with a novel pattern of AR expression in the tissues that support it. We suggest that such co-evolution of AR expression and sex-specific or species-specific signaling behavior exists across vertebrates.
