Even though human females are more choosy in accordance to [[Bateman's principle]], both sexes are ornamented. Women have [[Boobs|permanently swollen breasts]], an hour glass shaped body etc., men have a V-shaped upper body, more toned muscles, beards, very large penises compared to other great apes, and [[:Category:Aesthetics|various other features]]. Both sexes have clearly defined [[Hairline|hairlines]] and very clear skin. None of these features serve a known biological purpose 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. | Even though human females are more choosy in accordance to [[Bateman's principle]], both sexes are ornamented.
