Such feedback loops can explain the immense sexual attraction to superficial traits that humans exhibit, which have barely any relevance for survival except "social survival". | Such feedback loops can explain the immense sexual attraction to superficial traits that humans exhibit, which have barely any relevance for survival except "social survival". | ||
Some simple and elegant body shapes may however not necessarily be a result of aesthetic selection, but result of optimizing e.g. for resources efficiency or resilience | Some simple and elegant body shapes may however not necessarily be a result of aesthetic selection, but result of optimizing e.g. for resources efficiency or resilience favoring simple shapes, but this in turn could have initiated feedback loops in sexual selection. Attraction to sexually dimorphic beauty also increases fitness because seeking out the opposite sex is conductive for reproduction. | ||
Another explanation was provided that beauty is a costly signal of e.g. health, mutational load and intelligence, can thus signal ''good genes'' overall. These two opposing views the ''Good Geners'' vs ''Fisherians'' lead to significant academic rivalry since the 1990s, but the good genes hypotheses has largely been refuted since. | |||
It seems the relation of beauty to health and ability is mostly only relevant for extreme cases like disfigurement, certain syndromes and skin rashes and the like. | |||
Sexually dimorphic beauty and health are only weakly related when disregarding these extremes,<ref>Scientific_Blackpill#Attractive_people_are_perceived_much_more_positively_than_they_really_are</ref> but slight fitness advantages could have also initiated feedback loops in sexual selection. | Sexually dimorphic beauty and health are only weakly related when disregarding these extremes,<ref>Scientific_Blackpill#Attractive_people_are_perceived_much_more_positively_than_they_really_are</ref> but slight fitness advantages could have also initiated feedback loops in sexual selection. | ||
