Even though human females are more choosy in accordance to [[Bateman's principle]], both sexes are ornamented, e.g. women have [[Boobs|permanently swollen breasts]] and an hour glass shaped body, men have a V-shaped upper body, more toned muscles, beards and very large penises compared to other great apes. Both sexes have [[Hairline|clearly defined hair lines]]. None of these features serve a known biological purpose besides being good looking, so they're likely sexually selected and possibly by feedback loops like Fisherian runaway. | Even though human females are more choosy in accordance to [[Bateman's principle]], both sexes are ornamented, e.g. women have [[Boobs|permanently swollen breasts]] and an hour glass shaped body, men have a V-shaped upper body, more toned muscles, beards and very large penises compared to other great apes.

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 big boobs and [[Butt|booties]]. | 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 big boobs and [[Butt|booties]]. Men are of course ornamented because all women are choosy as hell (not just [[Stacy|alpha women]]). | ||
Sexual selection may not only concern physical appearance though, but also cognitive ability. While human females may not all be dull looking (as it is the case in many bird species), they have certainly rarely impressed by cognitive achievements in human history. | Sexual selection may not only concern physical appearance though, but also cognitive ability, in particular because human intelligence is unnecessarily sophisticated for the needs of hunter-gatherers to survive<ref>https://en.wikipedia.org/wiki/Evolution_of_human_intelligence#Sexual_selection</ref>.

While it is not proven that feedback loops were involved in shaping human ornament, or just sexual selection without feedback, it is certainly plausible, especially considering the importance people place on good looks. It could explain why people undergo great risks and costs merely for improving their looks, e.g. surgeries, diets or steroid intake. | While it is not proven that feedback loops were involved in shaping human ornament, or just sexual selection without feedback, it is certainly plausible, especially considering the importance people place on good looks.
