What is the evolutionary advantage of sexual selection? Being attractive is not synonymous with fitness

>>	Anonymous Mon Sep 18 21:55:10 2017 No.9177808 >Being attractive is not synonymous with fitness Yes it is? Do you find obese people attractive? How about people with Downs Syndrome? Just because it's not a perfect measure of fitness doesn't mean its not a good one.

OP, it is for the most part. Not just physically, but being witty and charming is a good sign of neurological health, social prowess and capability. also, the sexy sons hypothesis:

A healthy male is more likely to provide food and shelter for offspring. A healthy female is more likely to survive birthing offspring, more likely to enable child to survive birth as well because fewer complications, and mother can now help raising child or continue to birth new children. Healthy people produce more children who can survive to produce themselves, so it is evolutionarily supported

how are the people in OP's pic healthy?

They're young dumbsluts so they're probably poor and stupid. Plus they're way too skinny to make a healthy baby, as they have very little fat. And there's no indication that they are physically fit, they're very weak and fragile looking desu.

A fatter, older, more experienced woman would be more capable of taking care of children

Sexual selection is better than completely random mating (or no sexes at all - just cloning).
It does not mean it cannot go astray.

>Being attractive is not synonymous with fitness
Much more complicated. Many people find the weirdest things attractive - this is already an advantage as it leads to diversity.
But most often it's tits and phat ass - which means she is well fed, ready to procreate and won't have problems with child bearing.
If she is popular it's also a trait, as copulating with her upgrades your position in the pack and you'll be the first one to eat meat.

Only peacocks that thrive can support their huge displays.

What is unusual about humans is that women are the ones with the most pronounced display behavior (discounting homosexual men). An explanation might be the disparity between the productivity and social status of a male hunter versus a near helpless pregnant woman, obtaining his affections to crucial to reproduction. The roles are reversed, whereas the female peacock has all the resources she needs and has only to choose the fittest male, with humans (until recently) the woman must prove her fitness to prove she is worth investing resources in.

Sexual selection exists because its an evolutionary stable strategy. Genes which are considered attractive will be successful, not neccisarily because they provide an advantage in fighting or hunting, but simply because the majority of the opposite sex finds that phenotype attractive. Any deviation from the genetically determined attractive traits is a hinderance, and thus will not propagate.

If sexual selection exists why do I see pairs of ugly people? And no, they have no money or intelligence to equalize it. Shouldn't ideally all ugly people be forever alone? Sexual selection just sounds like a big meme to me.

Is this necessarily true?
1) infant mortality skews historical life expectancy to the low end
2) birthing ages being historically lower means shorter generation gap
If the above is true, you would be a grandparent by 30 or maybe earlier -depending on how far back you're talking. Beyond that there may be utility derived from caregiving as a division of labor. Old fucks cant hunt efficiently but they can act as caregivers while younger clan members hunt and forage.

Sexual selection is always based on some measure of fitness. But it can (and does) very quickly run amok.

Say a bird with a big red tail, where the females select for bigger tails. The offspring then has males with bigger tails and females with a preference for bigger tails. So tails keep getting bigger. At least until some other factor restrains it.

>run amok
Yes. In the sense that it goes beyond the simple utilitarian process of selecting a healthy mate. People can get attrackted to some very strange shit.
No. In the sense that we haven't developed big red tails. Although humans do display clear sexual dimorphism.
