In many vertebrates, courtship occurs through the performance of elaborate behavioral
displays that are as spectacular as they are complex. The question of how sexual selection …

From fiddler crabs to humans, animals perform repetitive displays showing neuromotor skill
and vigour. Consistent repetition of identical notes (vocal consistency) facilitates the …

According to classical sexual selection theory, complex multimodal courtship displays have
evolved in males through female choice. While it is well-known that socially monogamous …

Orgasm is one of the most intense pleasures attainable to an organism, yet its underlying
mechanisms remain poorly understood. On the basis of existing literatures, this article …

Organismal behavior, with its tremendous complexity and diversity, is generated by
numerous physiological systems acting in coordination. Understanding how these systems …

Understanding how and why behavioral traits diversify during the course of evolution is a
longstanding goal of organismal biologists. Historically, this topic is examined from an …

Superior physical competence is vital to the adaptive behavioural routines of many animals,
particularly those that engage in elaborate sociosexual displays. How such traits evolve …

Unrelated species often evolve similar phenotypic solutions to the same environmental
problem, a phenomenon known as convergent evolution. But how do these common traits …
