An alternative hypothesis for the evolution of same-sex sexual behaviour in animals
Same-sex sexual behaviour (SSB) has been recorded in over 1,500 animal species with a
widespread distribution across most major clades. Evolutionary biologists have long sought …

Same-sex sexual behavior in insects and arachnids: prevalence, causes, and consequences
Same-sex sexual (SSS) behavior represents an evolutionary puzzle: whilst associated costs
seem obvious, positive contributions to fitness remain unclear. Various adaptive …

Same-sex sexual behaviour and selection for indiscriminate mating
The widespread presence of same-sex sexual behaviour (SSB) has long been thought to
pose an evolutionary conundrum, as participants in SSB suffer the cost of failing to …

Rethinking same-sex sexual behaviour: male field crickets have broad mating filters
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 …

Ancestral sex-role plasticity facilitates the evolution of same-sex sexual behavior
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 …

Social relationship adjustments within the same sex promote marital bliss
X Shan, B Wu - Journal of Theoretical Biology, 2022 - Elsevier
Parental care is essential for biological systems. Marital bliss is one of the ideal paradigms
for parental care, in which males contribute in raising offspring and females require a …

[HTML][HTML] Experimental evolution with an insect model reveals that male homosexual behaviour occurs due to inaccurate mate choice
The existence of widespread male same-sex sexual behaviour (SSB) is puzzling: why does
evolution allow costly homosexual activity to exist, when reproductive fitness is primarily …

Male crickets in poor condition engage in less same-sex sexual behavior
Same-sex sexual behavior (SSB) is widespread among animals and is often treated as an
evolutionary anomaly or mistake. An alternative view is that SSB occurs because individuals …

Acceptance threshold theory can explain occurrence of homosexual behaviour
KC Engel, L Männer, M Ayasse… - Biology letters, 2015 - royalsocietypublishing.org
Same-sex sexual behaviour (SSB) has been documented in a wide range of animals, but its
evolutionary causes are not well understood. Here, we investigated SSB in the light of …

Intrasexual aggression reduces mating success in field crickets
Aggressive behaviour is thought to have significant consequences for fitness, sexual
selection and the evolution of social interactions, but studies measuring its expression …
