To warn potential mates you're past prime mating age?
To make you rely on skills & status rather than good looks
>>16535920There doesn't need to be an evolutionary advantage to things that happen past prime mating age. It's literally just a biproduct of DHT.
thats like asking whats the evolutionary advantage of arthritisits just a disease
>>16535920Those dinos didn't fight like that, they don't have the body shape for it. More likely they were showing off those sexy chrome domes and the female dinos were totally getting moist from it - just like how being a baldchad works in real life.
>>16535920More testosterone or similiar hormones outweighing the negatives. People used to have children before they turned into bald midgets, Tim.
>>16535920>To warn potential mates you're past prime mating age?That is retarded. There is no evolutionary advantage to such function, and it would be readily selected against. You must have completely failed to grasp the concept of natural selection to even suggest something like that
>>16535920Comparative fitness bonus for the men who don't go bald.
>>16535920thing about evolution is that it doesn't need to be always advantageous or disadvantageous. some shit just doesn't matter.
>>16535920I have another very VERY IMPORTANT gene-related question, pls.So, apparently all animals have the same old particular basic gene pack that is passed among species for at least 500mil years.The pack is simple, it contains 5 genes< each responding for development of torso, head, arms, legs, eyes. It's like a core script for all animals. And it's passed on and on, only external\functional features change(evolve) relevantly to surroundings, just like, for instance, the cars evolve, different shapes, speed, sizes, etc., but still the core gene script\formula stays the same, wheels, bonnet, doors, cabin, headlights, etc., and in case of ourselves and thus all animals our mass product gene script hasn't changed for half a billion years.So.The question is.What is the gene that is responsible for generation in any embryo of so called "self, personality, ego, I, me"?Personality, me, I, etc., is an obvious trick, illusion, that has a major driving force and power that drives this biorobotic body(and absolutely any animal's body) through hundreds millions of years of everyday battlefield on this planet, forces species to wake up every the morning and evolve to death, mate, hunt, kill, eat, dominate, argue, hate, love, collide with each other like those dinos on op pic., etc, etc?This "Me" or "I" gene has to be very much basic among these five fundamental genes that turn matter into a shaped living being.What are the studies about this gene?
>>16536086>what is the evolutionary advantage of muscle atrophyUhhhhh...
>>16535931If something is detrimental to the individual its worth examining if it evolved as a group survival tactic.
>>16538510>all animalsNo, only hoxozoa
>>16535920>What's the evolutionary advantage to baldness?Better cooling efficiency of the head/brain.Hotheads be gone.
>>16539050The gene that forms "I, me, personality" just has to be among those basic univeral\common genes that form torso, head, eyes, limbs. The studies show if you'll replace bull's eye forming gene with fly's eye-forming gene, the bull will grow healthy eyes, and vice versa. Same model should exist with the gene that forms "I, self, personality" an ability of any animal organism, first existing as an selfless bio-object, out of a sudden posess itself as an important unique being with aims and rights, basically the Me, I gene is the most important gene among all, it drives an abstract biomass organism to perform millions of evolutionary tasks.
>>16539106So male pattern baldness is proof of climate change is what you're saying
>>16535920It is not a disease, so it can only disappear through sexual selection. Nor has it happened because people used to produce offspring early enough so baldness was not visible, even for the unluckiest people like myself, who become full bald at 20. Also there are still many masculine alpha looking balds who continue to pass their genes. Another solution is cleaning the gene pool with a controlled baldie genocide.
>>16536122The domes were almost certainly used for impacting something, just maybe not doing the bighorn thing and impacting each other's domes that way. The weight and thickness of the dome would have no use in mating displays
>>16536133the evolutionary advantage is to have a young fit mate partner with strong sperm
>>16539029I don't get why they call them survival "tactics" or "strategies". These don't happen because the animal decide it, or the animal thought it was smart or anything. It's not a tactic or strategy since it's not planned and not intentional, Some thing can have an advantage or be a random change that just happens to be passed on, and out of the latter most end up being sexual selection, and others remain vestigial.
>>16538575Muscle atrophy did give an evolutionary advantage, there could be animals that didn't catabolize themselves and just died from a heart attack past a single day without eating, so the ones that could consume themselves survived longer than the rest. However as that anon said, baldness is not crucial for survival, I doubt women sexually selected it as they don't care about it now. At best a guy who happened to develop bald genes raped a lot of women and it stuck. Maybe neanderthal chicks liked bald guys.
>>16539472The "I" is a rather primitive concept that comes, foremost from cephalization, coordination of the primitive nervous system. The I wouldn't exist if parts of the animal moved randomly.The next part is consciousness, the ability that makes the animal act upon the environment prospectively. The animal exists and the environment is out there, he is driven to things and assesses perils. The last thing needed is language. As a refined consciousness system the animal now associates some abstract concepts with others. He knows his body is separate from things, he counts the number of bodies are 1. He rationalizes "I am one" and thus he assumes he is a single thing in the world.But in reality we are a coordinated system of many neurons. The brain is one but no one part of the brain is yourself, each little bit contributes to who you are, so instead of saying I you might as well say Us. Together we are I. Through our experience in the world we become Personality. This is the reason why twins are not the same entity.

>>16536133Old sperm causes just as many deliterious defects as old eggs
>>16538510I think you make a wrong presumption by asserting, that animals have the capacity to self-recognize. There is more than enough reason to believe they recognize others as different and seperate from themselves, but can't actually define themselves. There have been enough cases of animals raising kids from a completely different species and assimilating them into their social context. The assimilated animal, like a fox raised among dogs, will think of itself as part of the context it assimlated into, and tries acting accordingly. Only animals which recognize themselves in reflections, like elephants, have the ability to self-recognize outside of a superimposed context, meaning, that the genetic cluster you're looking for is likely not that an ancient pro-social gene, but probably some innovation form the last 100 million years
