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> | 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> | ||
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 that men strongly desire, but which serve no known biological purpose. | 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 that men strongly desire, but which serve no known biological purpose. Besides an outcome of sexual selection, the importance people put on looks in mate choice could be merely a spandrel of a general preference for aesthetics, or it could be driven by a link between good looks and overall [[good genes hypothesis|good and healthy genes]]. | ||
In industrialized nations, facial masculinity is unrelated to mating and [[reproductive success]] (RS). Strength and muscularity were also only weak, but consistent predictors of mating and RS.<ref>https://www.biorxiv.org/content/10.1101/2020.03.06.980896v3</ref> | In industrialized nations, facial masculinity is unrelated to mating and [[reproductive success]] (RS).

Women's hourglass shaped waist is also not linked to higher RS or better health.<ref>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6563790/</ref> Unless there are strong confounds in industrial nations, the absence of a link to RS means these traits are unlikely sexually selected. See the [[penis]] article for a discussion of the plausibility of sexual selection having acted upon it. | Women's hourglass shaped waist is also not linked to higher RS or better health.<ref>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6563790/</ref> Unless there are strong confounds in industrial nations, the absence of a link to RS means these traits are unlikely sexually selected.
