Feedback loops in sexual selection like Fisherian runaway may have played a role in the evolution of beauty in some animals, but unlikely in humans as good looking individuals in primitive societies do not have higher [[reproductive success]].<ref>https://doi.org/10.1016/j.evolhumbehav.2012.01.002</ref> Beauty could have evolved simply by aesthetic sexual selection in some animals, i.e. mate selection favoring objective [[beauty]] (simplicity). But feedback loops as mentioned above may have exaggerated aspects of it, leading to increased sexual dimorphism and amplified and narrowed the attraction to specific kinds of beautiful physical traits. This also stabilizes the phenotype, making it harder to adapt to environmental changes. Any sort of [[sexual dimorphism]], whether behavioral or physical likely tends to get reinforced by such feedback loops because [[sexual dimorphism]] is inherently attractive.<ref>https://incels.wiki/w/Scientific_Blackpill#Even_chickens_prefer_sexually_dimorphic_human_faces.2C_to_the_same_extent_as_humans</ref> The narrowing in preferences may explain the [[few millimeters of bone]] effect.
Feedback loops in sexual selection like Fisherian runaway may have played a role in the evolution of beauty in some animals, but unlikely in case of facial attractiveness in humans as there is no positive link with lifetime [[reproductive success]] in a variety of cultures.<ref>https://doi.org/10.1016/j.evolhumbehav.2012.01.002</ref>
It may also explain the disproportional importance people place on good looks and why people undergo great risks and costs merely for improving their looks, e.g. by surgeries, diets or steroid intake (see [[#zyzz|Zyzz's photo]]). It could also explain the phenomenon of being ''stunned'' by someone's appearance, double takes, as well as "love at first sight" and [[oneitis]], in fact "love at first sight" is nearly entirely explained by looks.<ref>https://incels.wiki/w/Scientific_Blackpill#Love_at_first_sight_can_be_predicted_by_physical_attractiveness</ref> However, each of these effects could also be merely a spandrel of a general preference for aesthetics, or it could be driven by a slightly correlation of good looks for healthy genetics.
Even though human females are more choosy in accordance to [[Bateman's principle]], it is women who seem to be more ornamented with their [[Boobs|swollen breasts]]<ref>https://doi.org/10.1016/j.evolhumbehav.2010.02.005</ref> and hour-glass shaped body. Though sexual preference for good looks could be merely a spandrel of a general preference for aesthetics, or it could be driven by a link between good looks and [[good genes hypothesis|healthy genetics]]

Inaccurate and boring:
Both sexes have clearly defined [[Hairline|hairlines]] and very clear skin.

<!--None of these features have survival value besides being good looking, so they're likely sexually selected, likely mostly by aesthetic selection common to many higher animals,<ref>https://www.apa.org/monitor/oct06/pretty</ref> and possibly by feedback loops like Fisherian runaway and sensory bias,<ref>Fuller, R. C., Houle, D., & Travis, J. 2005. ''Sensory Bias as an Explanation for the Evolution of Mate Preferences.'' [[https://www.jstor.org/stable/10.1086/444443 Abstract]]</ref> leading to exaggeration and strengthened sexual dimorphism.<ref>https://www.sciencedirect.com/science/article/abs/pii/S1090513810000279</ref> Though dominant and masculine features like [[hunter eyes]], large beards and a deep [[voice]] may also serve the intimidation of other males,<ref>https://www.sciencedirect.com/science/article/abs/pii/S1090513810000279</ref><ref>http://larspenke.eu/pdfs/Kordsmeyer_et_al_2018_-_Intra-_vs_intersexual_selection_on_human_males.pdf</ref>
but these adaptations in turn could be exaggerated again by runaway selection.
The fact that men have only reproduced half as often as women throughout human's evolution<ref>https://incels.wiki/w/Scientific_Blackpill#Before_.27enforced_monogamy.27.2C_women.27s_effective_population_size_was_up_to_17x_larger_than_men.27s</ref> suggests the most dominant men were primarily involved in selecting women's ornament.-->
