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, leading to exaggeration and strengthened sexual dimorphism. | Even though human females are more choosy in accordance to [[Bateman's principle]], both sexes are ornamented.

Women are likely mainly ornamented because throughout history, [[Chad|alpha males]] could freely choose among many women, could produce a large number of children and evidently repeatedly chose women with pronounced secondary sexual characteristics such as [[tits|big boobs]] and [[Butt|booties]]. Men are of course ornamented because ''all'' women are choosy. | Women are likely mainly ornamented because throughout history, [[Chad|alpha males]] could freely choose among many women, could produce a large number of children and evidently repeatedly chose women with pronounced secondary sexual characteristics such as [[tits|big boobs]] and [[Butt|booties]].
