分类群内和分类群之间信号特征的多样性是巨大而引人注目的，这促使我们考虑如何在动物交流的背景下进化新颖性。性选择有助于多样化，在这里，我们努力了解有助于维持或消除新的性信号和接收器特征的初始条件。新的发送者和接收者的变体可以通过突变、可塑性、杂交和文化创新来产生，然后发送者、接收者和环境的初始条件决定了新的线索是否成为信号。新的特征可能同时出现在发送者和/或接收者中。我们认为，进化出新的性信号可能比想象的要容易，因为性信号可能是任意的，性冲突很常见，接受者能够感知世界的更多方面，而不仅仅是现有的性信号。此外，信令环境的改变可以通过给定环境的传输特性的改变或使用新环境来近似信号和接收器的改变。人类世导致了环境的大范围破坏，因此可能产生直接观察新信号演变的机会，以解决系统发育方法无法解决的问题。
The diversity of signalling traits within and across taxa is vast and striking, prompting us to consider how novelty evolves in the context of animal communication. Sexual selection contributes to diversification, and here we endeavour to understand the initial conditions that facilitate the maintenance or elimination of new sexual signals and receiver features. New sender and receiver variants can occur through mutation, plasticity, hybridization and cultural innovation, and the initial conditions of the sender, the receiver and the environment then dictate whether a novel cue becomes a signal. New features may arise in the sender, the receiver or both simultaneously. We contend that it may be easier than assumed to evolve new sexual signals because sexual signals may be arbitrary, sexual conflict is common and receivers are capable of perceiving much more of the world than just existing sexual signals. Additionally, changes in the signalling environment can approximate both signal and receiver changes through a change in transmission characteristics of a given environment or the use of new environments. The Anthropocene has led to wide-scale disruption of the environment and may thus generate opportunity to directly observe the evolution of new signals to address questions that are beyond the reach of phylogenetic approaches.
