长期以来，生物学家一直着迷于动物王国中各种生物精心制作的求爱表演。求偶行为的进化通常需要神经、感觉和运动系统的特化。此外，令人印象深刻的展示也可能需要优化的代谢、呼吸和心血管系统来维持神经肌肉的需求。荷尔蒙信号可以同时到达所有这些组织，为求爱做好准备。对雄性金领金丝雀（Manacus vitellinus）的研究发现，雄性金领金丝雀（Manacus vitellinus）是一种生活在新热带地区的小鸟，在求偶时表现出强烈而嘈杂的生理反应。研究发现，雄性激素依赖的神经肌肉和代谢专一化，不仅使它们能够完成复杂的求偶程序，而且还使它们的进化过程更加夸张。然而，一种功能的生理特化可能会限制它们在其他目的上的应用。这种权衡可能会影响求偶的发展方式，但也可能为雌性选择配偶提供信息。我们回顾这一工作，着眼于扩大我们对广泛的组织激素敏感性和激素作用的进化的欣赏，作为精心设计的求爱行为进化的系统。(c) 2021动物行为研究协会。Elsevier Ltd.出版。版权所有。
Biologists have long been fascinated by the elaborate courtship displays performed by diverse organisms throughout the animal kingdom. The evolution of courtship behaviour often requires specializations of neural, sensory and motor systems. In addition, physically impressive displays may also require optimized metabolic, respiratory and cardiovascular systems to sustain the neuromuscular demands. Hormonal signalling can reach all of these tissues simultaneously to prepare them for use in courtship. Studies of male golden-collared manakins, Manacus vitellinus, a small bird of the Neotropics with a physically intense and noisy courtship display, have uncovered numerous androgen-dependent neuromuscular and metabolic specializations that enable not only the performance of elaborate courtship routines, but also their evolutionary exaggeration. However, physiological specializations for one function can create limits on their use for other purposes. Such trade-offs may influence the way courtship develops but may also provide information used by females for mate choice. We review this body of work with an eye towards expanding our appreciation of the evolution of widespread tissue hormone sensitivity and hormone action as the system through which elaborate courtship behaviours evolve.
