>Blonde hair proliferated through sexual selectionIs there any evidence for this? I’m a blonde man myself, but I honestly find it kinda hard to believe. I feel like in hunter-gatherer societies where sex and pregnancy were practically inseparable, neither men nor women would select mates based purely on sexual novelty. But maybe I’m wrong.
>>18386332You are brown.
>>18386332HOW DO YOU THINK THAT TRAITS ARE INHERITED, RETARD?PEEPEE GOES IN VAGOOGOO.
>>18386334I'm not OP, but out of curiosity how many brown people have you met with blonde hair?
>>18386334I’m white. My eyes are admittedly dark brown even though my hair is golden-blonde which is a pretty uncommon combination.>>18386335I get that. I just don’t buy that sexual selection was the driving factor in its proliferation. But I’m willing to listen to the arguments.
blond hair spread through farming and pastoral societies in Europe.
>>18386340>I get that. I just don’t buy that sexual selection was the driving factor in its proliferation. But I’m willing to listen to the arguments.NO, YOU DO NOT «GET IT».WHEN ONE CHOOSES SOMEONE WITH WHOM TO MATE, THAT IS SEXUAL SELECTION.HOW ELSE WOULD ANY PHENOTYPICAL TRAITS PROLIFERATE, ACCORDING TO YOU?
>>18386343Why though? What evolutionary advantage does it provide? Surely it must do something, otherwise why was it sexually selected for?
>>18386347The literature doesn't point to it being a trait that was sexually selected for.
>>18386345Maybe I’m misunderstanding, but I thought natural selection was when the environment selects for a phenotype and sexual selection was when mates select for a phenotype. So I was wondering if blonde hair was advantageous somehow, and that’s why it spread. The claim that it was sexually selected for because it was just novel/exotic to mates is something I find hard to believe.>>18386348That makes intuitive sense to me. Is there an alternative explanation?
>>18386354THE BLONDE TRAIT PROLIFERATES BECAUSE BLONDES REPRODUCE.WHAT IS SO DIFFICULT TO UNDERSTAND?
>>18386354It's a mutation. Appears to be selected for in northern climates for similar reasons to the lighter skin also selected for in those climates, basically Vitamin D, but it seems like it is not considered overly important. It may be a beauty standard in certain regions but that isn't necessarily sexual selection.
>>18386360I get that they reproduced, but why? Was it specifically because they were just more attractive to potential mates? Or did blonde hair confer some advantage for survival and reproduction? That’s what I’m curious about.
>>18386365BLONDES STILL EXIST, BR0.
>>18386338Aboriginal people do. I'm guessing he might be Australian.
>>18386362That makes sense. I’m kinda a brainlet on these topics so I appreciate the explanation.>>18386372I thought it was some Solomon Islanders (who are Melanesians I think)?
>>18386382No problem brah
>>18386338He doesn't have blond hair because he's brown, and he's seething
>>18386332the blonde hair isn't selected for. it's lack of melanin. the gene that produces skin melanin is the same one that produces hair and eye melanin. if you have too much melanin and live in a place with poor sunlight like the arctic you will get a vitamin d deficiency and die due to rickets and shit. lighter skin was selected in areas with less sunlight to prevent rickets
>>18386340>>18386345>>18386343>>18386347>>18386354it wasn't picked out for sexual attraction. the genes that impact skin color are either the exact same genes that do eye and hair color or they are located physically close together on the chromosome and are transferred together during crossing over. they were selecting for vitamin d/not getting rickets. blue eyes are probably kind of shitty for places white people live because they will allow in too much light during the day time. another exampled of this phenonium is the fact that headshape in foxes and dog are for some reason really close on the chromosome to the gene for being docile. that's why golden retrievers have such a round head compared to wolves
>>18387564You don't produce vitamin with your eyes, and the stuff about genes being close is also false. You are retarded
>>18387569you are a fucking retard. linked genes are linked because they are physically close together on the chromosome. here's a .gov link that even straight up says multiple skin color genes affect eye color you fucking retardhttps://medlineplus.gov/genetics/understanding/traits/eyecolor/>Several other genes play smaller roles in determining eye color. Some of these genes are also involved in skin and hair coloring. Genes with reported roles in eye color include ASIP, IRF4, SLC24A4, SLC24A5, SLC45A2, TPCN2, TYR, and TYRP1. The effects of these genes likely combine with those of OCA2 and HERC2 to produce a continuum of eye colors in different people.most genes aren't mendelian you fucking underaged retard and here's a .edu link from the university of minnisota describing linked genes being physically close to each otherhttps://pressbooks.umn.edu/ecoevobio/chapter/inheritanceextensions/>The segregation of alleles into gametes can be influenced by linkage, in which genes that are located physically close to each other on the same chromosome are more likely to be inherited as a pair. genes that are physically close to each other will typically undergo crossing over together and will typically be inherited as a pair and those are often called linked genes an easy example of this that they show retards is in fruit flies the wing length and eye color genes are next to each other on the same chromosome so they are USUALLY inherited together
>>18386332 You're wrong. Bertaud and Frost have proved in genetic studies that both men and women prefer a mate with the MC1R gene.
it's called recessive introgression, or something like that basically, recessive traits spread through a population gradually and aren't selected against because they aren't expressed phenotypically eventually they reach critical mass in the population's collective genotype and begin to be phenotypically expressed more oftenwhen this happens, this marker becomes a kind of identifier of in-group belonging and is subsequently reinforced
>>18387833it's not mendelian. recessive just means>doesn't code for a functioning proteinsee>>18387590the blonde hair blue eye stuff is linked to lighter skin and if you put a black person in Scandinavia they will suffer vitamin D deficiency
>>18387868>recessive just means doesn't code for a functioning proteinI thought you can have a recessive allele and it won't be phenotypically expressed, the protein will still function.If you mate with someone who doesn't have the recessive allele, there's a chance it propagates anyways.But if you mate with someone who is also a carrier, then there is a chance your child expresses a trait that neither parent does.Obviously this is an oversimplification and it's different depending on specific loci. Is very complex, I certainly don't completely understand how that works. But that explains the proliferation of certain recessive traits which can be situationally adaptive within a population even in environmental conditions where they are not adaptive, without appealing to subjective desire as a explanation.Basically, dominant genes can counterintuitively be more prone to selection because associated deleterious effects cannot be masked.
>whypipo women have broader hips, larger boobs therefor=more fertile to primitive brain>Primitive brain associates blonde with fertile>Women like peasants who see aristocracy doing a ritual start immitating by wearing wigsThis was done in rome btw, bald roman men would scalp a germanic woman and wear her hair as a wig to humiliate the men who were powerless to defend the women.
>>18388115more on that?
>>18388115>This was done in rome btw, bald roman men would scalp a germanic woman and wear her hair as a wig to humiliate the men who were powerless to defend the women.damn how cruelguess the multiple times rome was pillaged were justified
>>18388117>Ovid amores 1.14Now Germany will send you captive tresses;you'll be safe, adorned by the gift of a conquered race.How often you'll say, when someone praises your locks:"This hair belonged to another before it was mine!"
>>18388096>I thought you can have a recessive allele and it won't be phenotypically expressed, the protein will still function.>If you mate with someone who doesn't have the recessive allele, there's a chance it propagates anyways.>But if you mate with someone who is also a carrier, then there is a chance your child expresses a trait that neither parent does.obviously most things are not mendelian, but recessive means doesn't code for a functioning protein or doesn't code for a protein that gets phenotypically expressedand easy example for this would be blood typeA, B and RH+ all code for proteins on the outside of a blood cell and are dominant. O and RH- don't code for proteins and are negative. I'd argue something like sickle cell isn't really dominant/recessive because the "recessive" sickle cell gene does code for a protein and is phenotypically expressed. Someone with one sickle cell gene and one wild type gene will be less likely to get malaria than someone with 2 wild type genes>Basically, dominant genes can counterintuitively be more prone to selection because associated deleterious effects cannot be masked.most genes are not mendelian. For something like hair, skin or eye color what we are seeing is that there are a number of genes that impact the creation of melanin and in someone with lighter skin they have a higher number of these genes which have some form of "defect" that renders them nonfunctioning when compared to a black.
If it was sexual selection it wouldn't be so correlation latitude.
>>18386332>I’m a blonde man myselfTwink.
>>18388115>>whypipo women have broader hips, larger boobs therefor=more fertile to primitive brainNo the fuck they don't lmao. Brown women do. White women coast by on hair and eye colour. A PAWG is very rare.
>>183863321. Blonde women were fucked more and therefore gave more offsprings.2. They were fucked by the elite men.3. Elite men evetually became blonde because of their blonde mothers4. They continued to pass blonde genes, making blonde hair even more common.
>>18386332All evolution is these sort of post -hoc just so stories.
>>18386332I'm of the opposite belief. I think HGs were schizos and when they found weird features they thought it was some divine shit and lined up to gangbang the village blonde and then it spread from there
>>18389188the genes for skin color, hair color and eye color are all linked and you need light skin the farther you are from the equator of you get rickets
>>18386332Like 2% of humans have blonde hair and they’re all in Sweden
>>18386340>I just don’t buy that sexual selection was the driving factor in its proliferationId' say this is mostly an argument about to which extent or if at all natural selection even applies to humans anymore.Socioeconomic factors probably play a much larger roll in how many offspring anyone has than anything genetic
