Comparative studies of vertebrate hearing organs have enabled an integrated approach to difficult questions related to function. Recent evidence for the independent evolution of similar hearing-organ specializations, in particular hair-cell differentiation, has helped identify common problems of hearing receptors and put them in a new perspective. Evidence that cochlear amplification is an ancient phenomenon has widened the search for the motor mechanism involved. In this regard, different hypotheses are best examined by making optimal use of natural structural variations. Studies on the evolution of the efferent system have provided new routes to investigate its function.
对脊椎动物听觉器官的比较研究为解决与功能相关的难题提供了一种综合方法。近期有关类似听觉器官特化（尤其是毛细胞分化）独立进化的证据，有助于识别听觉感受器的常见问题，并为其提供了新的视角。耳蜗放大是一种古老现象的证据拓宽了对相关运动机制的探索范围。在这方面，通过充分利用自然结构变异来最好地检验不同的假说。对传出系统进化的研究为探究其功能提供了新途径。
