In work done by (Bateman, 1948) buliding up on Charles Darwin's theory of sexual selection, with particular focus on Intra-sexual selection in Drosphilia has found that intra-sexual selection acts primarily on males (Bateman, 1948), with males that have obtained an higher amount or being surronded by female mates regularly showing relative or increased pickiness (Bateman, 1948), with males showing less pickiness or less ablity to discriminate based on color which was measured here (Bateman, 1948) in the course of the study. It also suggests that males are subject to stronger sexual selection comparatively to the females of that species, and that contribution of said males is more variable and depends on sexual attraction on looks. Through, analysis/interpretation, it could be found that males are typically more attractive or exhibit more attractive traits compared to the females of that species. I would now like to forward you to the work of Anderson, 1994 and his book on sexual selection. The key conclusion of the book is this:
In studies done by Arquivist (1991), they mention how sexual selection was developed out of sexual conflict and sexual attraction
According to studies done by Burley 2006, females are condition-dependent for sexual selection and mating, and if subjected to an high environmental pressure or socialogical one, then that pressure can override mating and mating selection.
Studies by DuVal(2023) showed that female sexual selection is subject to changed and results on copying others or more experienced females in their sexual selection.
ON HUMANS:
This is the third part of the argument which will discuss sexual selection on humans and discrimination towards attraction in humans.
Women are more likely to feel disgust or hatred towards an unattractive man as (Zsok 2017) found out.
Waynforth D. (2001) puts out this argument suggesting that women trade attractiveness for resources.
And about Luo, S., & Zhang, G. (2009)'s study on speed dating where they found this out:
Arguing further, I would like to push the idea that females evolve discrimination rather than ornamentation; while males evolve ornamentation, and lack an capacity to discriminate, which is an idea first synthesised by Darwin in his work The Descent of Man; And Selection in Relation to Sex. In work done by Vincent 1990, they have argued that the sex with the highest ablity for variance leads to the development of more ornamental or more beautiful traits. These studies prove the first part of the claim, the fact that men are selected on average for more attractive traits.“Sexual selection typically leads to males evolving conspicuous ornaments and displays, while females remain comparatively cryptic.”
In studies done by Arquivist (1991), they mention how sexual selection was developed out of sexual conflict and sexual attraction
The study suggests that females are generally resistant to mating with males; and require an high amount of male stimulus for mating leading to high amounts of ornamentation in the male population.In contrast to tradition explanations of costly female mate choice, which rely on indirect genetic benefits, our model shows that mate choice can be generated as a side-effect of females evolving to reduce the direct costs of mating.
According to studies done by Burley 2006, females are condition-dependent for sexual selection and mating, and if subjected to an high environmental pressure or socialogical one, then that pressure can override mating and mating selection.
Female finches spent less time associating with attractive males when their wings were clipped than when wings were intact. (Burley 2006)
Collectively, these results indicate that a female's mate selectivity is dynamically adjusted based on her assessment of her own condition or mate-getting ability. (Burley 2006)
These findings showed that sexual selection is dynamic, and the female is aware/reasons about said selection.we performed a companion experiment that measured male mate choice of females with clipped versus intact wings; no discrimination against clipped females was found. (Burley 2006)
This suggests an process of mate discrimination and that ornamentation relies in their ablity to differentiate one from one's own group or species; suggesting an independence in males of that species which females of that species lack.Over several generations, female preferences caused rare male traits to
become more common, which then made them less attractive. This
helped to maintain variation in male traits, rather than a single attractive
trait out-competing the others
Studies by DuVal(2023) showed that female sexual selection is subject to changed and results on copying others or more experienced females in their sexual selection.
This proves the second part of the argument.Females may infer what makes a male attractive by observing the
choices of more experienced females, and the context of those choices
matters, according to a mathematical model published October 3rd in the
open access journal PLOS Biology. Rather than simply copying their
peers, females might learn to prefer rare traits that set successful males
apart from others
ON HUMANS:
This is the third part of the argument which will discuss sexual selection on humans and discrimination towards attraction in humans.
Women are more likely to feel disgust or hatred towards an unattractive man as (Zsok 2017) found out.
(Crosby et. al 2021) found the same results with female participants feeling more disgust and hatred towards an unattractive male.The results suggest that women feel disgust at sexual contact with unattractive or diseased men independently of their sexual arousal.
Grammer, K., & Thornhill, R. (1994) found that facial symmetry has an effect on attractivenessWe found support for our prediction that women had higher levels of sexual disgust than men, but only after addressing the confounding sex difference in target attractiveness. We also found the predicted negative association between target attractiveness and sexual disgust. Finally, as predicted, sexual disgust levels were more strongly related to potential mates’ attractiveness in individuals who perceived there to be many available mates in their local environment.
(Mate selection)The hypotheses were supported, with the exception of the hypothesized effects of averageness of female and male faces on attractiveness ratings. This is the first study to show that facial symmetry has a positive influence on facial attractiveness ratings.
Waynforth D. (2001) puts out this argument suggesting that women trade attractiveness for resources.
According to Peters (2024), sexual attraction underlies the formation of any long-term romantic relationships with human females.This pattern may imply that women trade off attractiveness for resources in mate choice. Here I test whether a trade-off between resources and attractiveness seems to be occurring in the mate choice decisions of women in the United States. In addition, the possibility that the risk of mate desertion drives women to choose less attractive men as long-term mates is tested.
And about Luo, S., & Zhang, G. (2009)'s study on speed dating where they found this out:
The strongest predictor of attraction for both sexes was partners' physical attractiveness.
