一个基本假设的进化和维护的装饰特征是，装饰品传达信息，选择女性的质量，未来的配偶。各种各样的装饰品（e）。例如，在一个实施例中，颜色、形态特征和行为）与广泛的个人品质测量有关，但对这些指示性状的数十年研究未能产生诚实信号的一般机制。在这里，我提出，作为线粒体功能的产物，细胞呼吸的效率是各个分类群广泛性状的装饰与性能之间关联的基础。大量的生物医学文献记载了氧化磷酸化（OXPHOS）和活性氧（ROS）的产生、代谢过程、免疫系统的功能、蛋白质的合成以及神经系统的发育和功能之间的基本生物化学联系。几乎所有的装饰品的生产，其表达已被证明是条件依赖性的直接影响的细胞呼吸的效率，这表明呼吸效率的信号可能是这些性状的主要功能。此外，通过线粒体功能，装饰物的产生与应激反应系统，特别是神经内分泌系统有关，从而使装饰性状成为承受环境扰动能力的有效信号。诚实信号的统一机制的确定有可能将许多迄今为止与压力和应激相关的不同研究领域联系起来，包括神经内分泌学，呼吸生理学，代谢生理学和免疫学。
A fundamental hypothesis for the evolution and maintenance of ornamental traits is that ornaments convey information to choosing females about the quality of prospective mates. A diverse array of ornaments (e. g., colors, morphological features, and behaviors) has been associated with a wide range of measures of individual quality, but decades of study of such indicator traits have failed to produce general mechanisms of honest signaling. Here, I propose that efficiency of cellular respiration, as a product of mitochondrial function, underlies the associations between ornamentation and performance for a broad range of traits across taxa. A large biomedical literature documents the fundamental biochemical links between oxidative phosphorylation (OXPHOS) and the production of reactive oxygen species (ROS), the process of metabolism, the function of the immune system, the synthesis of proteins, and the development and function of the nervous system. The production of virtually all ornaments whose expressions have been demonstrated to be condition-dependent is directly affected by the efficiency of cellular respiration, suggesting that the signaling of respiratory efficiency may be the primary function of such traits. Furthermore, the production of ornaments links to stress-response systems, including particularly the neuroendocrine system, through mitochondrial function, thereby makes ornamental traits effective signals of the capacity to withstand environmental perturbations. The identification of a unifying mechanism of honest signaling holds the potential to connect many heretofore-disparate fields of study related to stress and ornamentation, including neuroendocrinology, respiratory physiology, metabolic physiology, and immunology.
