Interaction-Independent Sexual Selection and the Mechanisms of Sexual Selection [PDF]
Darwin identified explicitly two types of sexual selection, male contests (combat and displays) and female choice, and he devoted the overwhelming majority of his examples to traits that influence the outcome of these interactions. Subsequent treatments of sexual selection have emphasized the importance of intra- and intersexual interactions as sources

Evolution of sexual size dimorphism in mammals: Sexual or natural selection? [PDF]
Sexual size dimorphism may have evolved through two processes: sexual or natural selection. The sexual selection theory states that males compete for mate monopolization and larger males can sire more offspring than smaller ones—factors that resulted in ...

Sexual selection for males with beneficial mutations
Sexual selection is the process by which traits providing a mating advantage are favoured. Theoretical treatments of the evolution of sex by sexual selection propose that it operates by reducing the load of deleterious mutations.

Postcopulatory sexual selection [PDF]
The female reproductive tract is where competition between the sperm of different males takes place, aided and abetted by the female herself. Intense postcopulatory sexual selection fosters inter-sexual conflict and drives rapid evolutionary change to generate a startling diversity of morphological, behavioural and physiological adaptations.

The impact of COVID-19 on sexual health: a preliminary framework based on a qualitative study with clinical sexologists [PDF]
Introduction: In recent months, some attempts were made to understand the impact of COVID-19 on sexual health. Despite recent research that suggests COVID-19 and lockdown measures may eventually impact sexual response and sexually related behaviors, we ...

Intralocus sexual conflict diminishes the benefits of sexual selection. [PDF]
Evolution based on the benefits of acquiring "good genes" in sexual selection is only plausible with the reliable transmission of genetic quality from one generation to the next.
