Sexual selection in plants [PDF]

open access: yesCurrent Biology, 2011
SummaryDarwin's theory of evolution by natural selection provided an immediately convincing explanation for the close fit between form and function in nature that had previously only been explicable in terms of supernatural design. Traits evolved in a way that improved their bearer's chances of survival and its success at producing offspring.

The sexual selection of endometriosis.

open access: yesEvolutionary Behavioral Sciences, 2023
Selection can generate risk of maladaptive extremes in sexually dimorphic and sex-limited traits. In humans, such extremes commonly manifest in diseases associated with sex and reproduction. Endometriosis involves endometrial tissue that proliferates at non-uterine sites.

Sexual selection in a transparent worm : insights from fluorescent sperm [PDF]

open access: yes, 2015
Sexual selection is a potent source of selection underlying the evolution of sexual dimorphism, reproductive strategies and mating systems. Although sexual selection was initially thought to occur exclusively at the pre-copulatory stage (e.g., contests ...

Beyond sex allocation : the role of mating systems in sexual selection in parasitoid wasps [PDF]

open access: yes, 2014
Funding: UK NERC Doctoral Training GrantDespite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked.

Darwin's Explanation of Races by Means of Sexual Selection [PDF]

open access: yes, 2012
In _Darwin's Sacred Cause_, Adrian Desmond and James Moore contend that "Darwin would put his utmost into sexual selection because the subject intrigued him, no doubt, but also for a deeper reason: the theory vindicated his lifelong commitment to human ...

Sexual Selection and Proteinaceous Diversity in the Femoral Gland Secretions of Lacertid Lizards

open access: yesDiversity, 2023
Sexual selection contributes to the diversity of chemical signals in various animal groups. Lizards are good model species to study how sexual selection shapes signal diversity, as they are a chemically oriented taxonomic group with different levels of ...

Sexual selection on song and cuticular hydrocarbons in two distinct populations of Drosophila montana [PDF]

open access: yes, 2011
Sexual selection has the potential to contribute to population divergence and speciation. Most studies of sexual selection in Drosophila have concentrated on a single signaling modality, usually either courtship song or cuticular hydrocarbons (CHCs ...

The sexual selection continuum [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2002
The evolution of mate choice for genetic benefits has become the tale of two hypotheses: Fisher's 'run-away' and 'good genes', or viability indicators. These hypotheses are often pitted against each other as alternatives, with evidence that attractive males sire more viable offspring interpreted as support for good genes and with a negative or null ...

Runaway sexual selection without genetic correlations : social environments and flexible mate choice initiate and enhance the Fisher process [PDF]

open access: yes, 2012
Female mating preferences are often flexible, reflecting the social environment in which they are expressed. Associated indirect genetic effects (IGEs) can affect the rate and direction of evolutionary change, but sexual selection models do not capture ...

Sexual selection and trust games [PDF]

open access: yes, 2010
In economic games the facial attributes of counterparts bias decisions to trust and decisions to enter play. We report research supporting hypotheses that trust and reciprocation decisions in trust games are biased by mechanisms of sexual selection ...
