Is there an evolutionary reason for male pattern baldness?
Large brains have to be kept cool.Light reflecting off the bald head blinds an opponent during a fight.Missing hair cannot be grabbed by an opponent during a fight.Balding indicates high testosterone.Baldness motivated development of the intelligence to invent hats.Brain-enhancing cosmic rays from space are effectively blocked by hair.Bald heads are aerodynamic, facilitating faster movement through air and water.Early cultures used the exposed skin as space to post product advertisements.
>>16784706Men working and keeping short hair anyway.Most of your bodily heat radiates out of your head. Hair absorbs heat and keeps it near the head and body. Useful in winter but any moron can put on a hat.
>>16784796leftout>more space to absorb vitamin D
>>16784706I don't think there is in the sense that baldness itself has any advantage. It's as prevalent as it is despite seen as undesirable because men reproduced/died early enough (largely before MPD got to an advanced stage) in our ancestral environment that it didn't get selected out.
>>16784706What’s the evolutionary reason for women hitting the wall at 30?
>>16784706Certain women think it's hotThat's all there is to itThe muscular, bearded bald dude, is as primal as it gets And that turns them on
>>16784706Possibly not. There is a purpose to have hair during reproductive age but once you pass your best by date evolutionary pressures become more abstract e.g. senescence and advertisement thereof.
>>16785000>largely before MPD got to an advanced stage*MPB (Male Pattern Baldness) obviously
>>16784706As far as we know, it's something to due with variations on the X chromosome. Given that women get an X chromosome from both parents, while men get an X chromosome solely from their mother, it might be a circumstance where the genes that correlate/cause male pattern baldness in men are related to something evolutionarily beneficial in women.That sounds like a just-so story, but that's my hunch if I had to guess.
>>16784706God punishes you for touching your dick with being a baldcel.
>>16784706>Is there an evolutionary reason for male pattern baldness?To make you look handsome
Hair loss correlate with tightness and blood flow on the scalp. And its consistent with that on both male and females, despite the hair follicles having different tolerances to how little blood they can have before starting to shut down.As far as I am aware, baldness is to some degree solved. But unless you are 10-15, you are not in the right place to start scalp massaging to get a full range of motion on top of your head, meaning you are going to experience some form fo the Norwood reaper.More likely its just pressured by sweet glands and skull shape, meaning its a side effect of more important evolutionary traits.
>>16784706It’s a form of punishment by the previous retarded god that took yashuas power to white men
>>16784706yes, but not in the sense you mean.Evolutionary reason is often "Side effect of something else. Not very important for survival. Don't give a fuck. Won't optimize it"
>>16786078>evolutionary traits prop up to aid survivalfucking idiot, they're selected because they're desirable for reproductive success.
>>16785144Oh shit I'm in trouble!
>>16785000>>16785099All that implies is there once were alleles in the gene pool for going bald even earlier, i.e., at puberty, but those were selected out. Spoopy
>>16784706I always thought it odd that hair loss is very predominant in North Germanic people who would benefit from having lots of hair in their winters to whereas people in very warm climates typically have full heads of hair well into old age.The only thing I can think of is that Germanics had to develop the ability to think ahead in order to survive winter so perhaps the added iq of that causes them to suffer from far more stress then say Africans who hardly have a concept of the next day.
>>16784706A trait doesn't need a reason to persist, it needs a reason to go away. Balding is pretty neutral so it persists.
>>16786476It's not unheard of for people to start balding or even go completely bald in their teens
>>16785144Anon, no no no. I'm a terminal gooner.
>>16784706Breed before it becomes a problem.I hate retards that think evolution plays a roll after reproduction, evolution wouldn't care if parents exploded after their children were independant.
>>16784706>Is there an evolutionary reason for male pattern baldness?Genes mutated to cause male pattern baldness which spread to offspring and drift in a population for various reasons. That is the "evolutionary" reason for male pattern baldness. Were you trying to ask is there a gene propagation advantage to male pattern baldness but instead lazily used "evolutionary" as a meaningless and counter intuitive filler word like most retards?
>>16787207>evolution wouldn't care if parents exploded after their children were independantEvolution doesn't care about anything first of all. But to make a more intellectual point: many animals nurse and protect their young. It's certainly beneficial in many niches for parents to survive after birth, but not always of course. Sea turtles completely abandon their offspring because they couldn't help them if they stuck around. Human babies meanwhile need the most parental care of possibly any animal in existence. Many theorize that is a tradeoff to nurture human brain development which has an enormous return on investment
>>16787260Wow, if only I had said>after their children were independant
>>16787263lol ok I didn't read the last part of that sentence since the first part was so wrong. It is still not correct as a universal blanket statement though. For instance older animals, that have grown up independent offspring that MIGHT be in the same herd, could serve as a diversion to predators attacking the herd. If a predator eats the old infertile "useless" herd members first the younger fertile ones can escape. That's beneficial to spreading genes. It really doesn't need to be in a herd either. One infertile adult animal as a predator's meal is one less animal child that needs to be eaten that day.
