Background Evidence of male-male courtship display is widespread across the animal
kingdom. Yet, its function and evolutionary origin remain unclear. Here, we hypothesise that …

Recent attempts to explain the evolutionary prevalence of same-sex sexual behavior (SSB)
have focused on the role of indiscriminate mating. However, in many cases, SSB may be …

Same-sex sexual behaviour (SSB) occurs in many animals and is often treated as an
anomaly requiring special explanation. One common explanation for SSB is mistaken …

Aggressive behaviour is thought to have significant consequences for fitness, sexual
selection and the evolution of social interactions, but studies measuring its expression …

Reverse mounting has been extensively documented across avian taxa but has not received
significant attention from behavioural ecologists or evolutionary biologists. In this review, we …

Evolutionary loss of sexual signals is widespread. Examining the consequences for
behaviours associated with such signals can provide insight into factors promoting or …

Finding a mate is the central task in the lives of many male insects. In many solitary bees,
sexual competition between males is high due to monandry and a pronounced male-biased …

In this Letter, I briefly respond to the scientific shortcomings of Barron's (2020) recent
Commentary in which he discussed the evolution of same-sex sexual attraction and …

Understanding the conditions which promote adaptation is a key goal of evolutionary
biology, and a pressing issue across fields of biology. Addressing this involves investigating …
