Insects must wonder why mammals have ears only in their head and why they evolved only one common principle of ear design – the cochlea. Ears independently evolved at least 19 times in different insect groups and therefore can be found in completely different body parts. The morphologies and functional characteristics of insect ears are as wildly diverse as the ecological niches they exploit. In both, insects and mammals, hearing organs are constrained by the same biophysical principles and their respective molecular processes for mechanotransduction are thought to share a common evolutionary origin. Due to this, comparative knowledge of hearing across animal phyla provides crucial insight into fundamental processes of auditory transduction, especially at the biomechanical and molecular level. This review will start by comparing the evolution of hearing between insects and mammals to bring together results from both auditory research communities. The discussion of current findings about sound reception will help to bridge the gap between both research fields.

弥合哺乳动物和昆虫耳朵之间的鸿沟 - 声音接收的比较视图

昆虫一定想知道为什么哺乳动物的耳朵只长在头上，为什么它们只进化出耳朵设计的一个共同原则——耳蜗。耳朵在不同的昆虫群体中至少独立进化了 19 次，因此可以在完全不同的身体部位找到。昆虫耳朵的形态和功能特征与其所利用的生态位一样多样化。在昆虫和哺乳动物中，听觉器官都受到相同的生物物理学原理的约束，并且它们各自的机械转导分子过程被认为具有共同的进化起源。因此，动物门听觉的比较知识提供了对听觉转导基本过程的重要洞察，尤其是在生物力学和分子水平上。本综述将首先比较昆虫和哺乳动物之间的听觉进化，以汇集两个听觉研究界的结果。关于声音接收的当前发现的讨论将有助于弥合两个研究领域之间的差距。
