That form was too short-sighted. There’s several ways a body can grow more resistant to physical impact without the need for major structural changes. The wonderful world of science fiction futurism is full of examples of humanoid alien beings with clever adaptations to make them a sturdier humanoid without sacrificing their form. Stuff like titanium-coated bones, which is technically possible with mushrooms that use coal & obsidian to make them more resistant to being eaten by insects. Or the iron snail that’s shell is made out of absorbed iron it eats in its environment. A planet with a higher titanium content might see the rise of species that utilize the abundance to strengthen and reinforce their frame.
Lmao who needs armor when you can just be a fat orb? It’s hard to move as a fat orb tho so lets live in an enviroment that can support our weight. Oh also lets develope fins and sonar to navigate said enviroment. And now the optimal human design is “whale”. Great

I always thought that our balls having no protection was a bad design flaw. The ability to be taken down by a minor tap on the crotch is such a stupid weakness.
Almost all mammals have external balls, without a natural defense of them, so logically there must be an overwhelming advantage to external balls, or they wouldn't have been chosen for across most species. My understanding is that the sperm need the temperature difference to be effective at being sperm and fertilizing eggs. Probably the advantage of breeding super successfully overwhelmed the few unfortunate guys that took a random nut shot. Also consider that every male does not need to breed, we just need all the females to get preggers, and a few lucky guys can take care of that, no problem ;) We men are very expendable as a gender, and were much more so in the ancient past, so as long as enough guys survived to adulthood, we could easily lose 10-20 % of males, and still do fine as a species. Also, on most mammals, the crotch is pretty well defended by its position UNDER a quadruped's body, in the rear, but not exposed from the back. On four legs, its pretty hard to take a crotch hit, so we are an unusual evolutionary design, that has less protected balls, to gain running upright and use our hands for tools, and these things are probably far more useful on the ancient plains of Africa than good defensive ball positioning.
Yeah, I think it ends up being a thing to do when how body plans work. Pretty much the fact that balls and ovaries are basically encoded and developed the same to a certain point during gestation makes them very efficient genetically. Only needing a location change some additional genes and hormones makes this way easier from a developmental stand point. It allows A lot more commonality in genetics between male and female.

Idiocracy (2006) Opening Scene: "Evolution does not necessarily reward intelligence. With no natural predators to thin the herd, it began to simply reward those who reproduced the most, and left the intelligent to become an endangered species."
@@Walthu_99.5Actually it is. Evolution isn’t about intelligence; it’s about survival. If you need intelligence to survive, that will be selected for. But if it loses its importance, it won’t be selected for. Look at where we are. Anything you want to know or do can be found on the Internet or AI can out-think and out-do anything you can. Just see the school system: teachers don’t care whether students learn the information and it’s all about the grade rather than the education. So as a result, students are using AI to do their homework. You won’t learn anything that way but it gets you the result you want with a fraction of the effort (isn’t that the purpose of all technology starting with the wheel?) So pretty soon, intelligence won’t really matter. It’ll just be about whether you can get the results people want.

Fun fact: the strongest selection of beneficial genes takes place up to the age of sexual maturity. Genetic diseases that kill you *after* sexual maturity will already have been passed on to your offspring. That's why so many chronic illnesses hit for the first time in the late teens. If humans had evolved with sexual maturity not hitting until aged 50, we'd see the majority of people enjoying good health going into our 50s.
Fun fact: We can do this ourselves by actively choosing to have children later in life. And it'd help with the overpopulation problem killing the planet.
But you forget that that limits the rate at which we can reproduce. One of our evolutionary jumps was a younger sexual maturity relative to our maximum age. And most assuredly got us through some hard evolutionary time. Unfortunately it's one of those traits that is also less beneficial now as even an age into our 20s would make worlds of difference in our mental maturity now.

About the hair on our heads. The purpose of the hair described in the video undoubtedly is the main one.

Oh, don't worry man, I've just shoved a huge load of dopamine into some parts of your brain. You just need your buddy to give you a push to get that important thing you got last time...how do I know it's important? Well the cognitive brain said it is. It's not like it could be wrong, right?!?! And the rest of the brain praised songs of delight when you got whatever that was! So go man!"

Shoes are meant to keep our feet safe from debris and cuts which can cause infection. The problem is that we took it too far. Shoes that restrict toe movement can cause foot and even back problems. However, there are shoes meant to replicate how we would naturally walk without them, bringing the best of both worlds. Ofc, barefoot is still best if you can pull it off
There is another possible point to our hair outside of temperature regulation. Our hair knots very easily and just keeps growing to unusual lengths. It will twist and weave itself together by just moving around especially when very curly. And to keep it as orderly and unknoted as we do you need a comb or a brush. Our hands by themselves not being enough to do more than to seperate the hair into seperate knotted bushles. Basically dreadlocks, which may be the oldest hair style of our speciess, and in a way our natural one too. But what for us today is an annoyance, may have very well been a boon for our ancestors. Because hair is very strong and resilient, when knoted so much it basically becomes felt, it will create extreamly durable and cushioning structures. Likely even increasing the capability to deal with temperature even more, as hair felt is extreamly breathable, can cool when sweat evaporates thrugh it from underneath but also insulate to the heat on the outside. While it also would potected against cuts and blunt impactes. For a species that puts more and more energy into their brain, and uses it as it´s most important tool for survival while also being the most vulnearble placed high above ground and exposed on top. So a head of tightly knotetted hair, will act quite well as natural armour, protecting from cuts by sharp objects or claws and cushining from impacts by fall or running into something. While the ends that wear of and fray away are constantly replaced by our fast and long growing hair from below. Like some dogs, breed to also have fur that grows long and felts to give them a protective coat when used for hunting. For an animal that has such a need for it´s large yet fragile brain, and that while well protected by the skull is still quite suceptible to blunt impacts, that would be an evolutionary boon.
@theexchipm'k You wrote your comment yourself - BRILLIANT! Combs were developed due to insect infestations eg Head-lice and ticks. Many people across the world only use their fingers to groom their hair, usually someone else's - this is normal behaviour of most creatures. Grooming strengthens bonds through physical contact between others, family, groups or with inter-species. Long hair is/was plaited or bunched, which is easier to manage. Adornments were very often added into the plaiting, such as shells, pieces of wood, beads etc... From England.
Our bodies are not badly designed, they're badly maintained. Human beings are naturally the greatest endurance runners the world has ever seen, capable of stalking prey a hundred times their size or more for days without stop and taking said prey out with consumate ease. We're not weak, we're horrifically over powered. We simply changed our diet, exercise habits and social structures over the course of a mere five thousand years. That's not long enough for us to adapt to a dynamic that is completely opposite of what we have done for the past fifty to one hundred thousand years. We're not evolved to be sedentary, plant eating animals. We are omnivores but adapted to have the majority of our diet be meat, we're adapted to consume a large carbohydrate intake because we're supposed to be almost constantly in motion. Without the constant motion we store carbs since our ancestry adapted this due to frequent periods of starvation. Of course most of this is just theory but it's theory that makes sense with the data we have.

A note about genetics: six fingers on a hand-as is common in Amish communities-is dominant over a five-fingered hand I don't see five fingers going anywhere ant time soon, and indeed it might be that five fingers is ideal. When you look at certain tools like wrenches, you notice that you need all five fingers to operate them. Two sets of two fingers can give two manipulative pincers while the thumb creates a strong closing grip. Or you can hold two items in one hand and switch back and forth dextrously between them. I've held a pencil and a click eraser in the same hand and switched use without switching tool position. However, I don't see six fingers going away, any more than the palmeris longus, a throwback trait that is absent in about a quarter of the population. Or even the recurrent laryngeal nerve which takes an unnecessary dip underneath the aorta. It worked well in fishes, but not for us, and certainly not for giraffes in which it is a couple of meters longer than it really needs to be. Unless a trait is pressured against in the environment, it won't go away. And even the foot -which I malign for its many and fragile bones (can be broken with a good hard stomp) - has an elegance born of its many joints. The toes allow us to become ungulagrade (running on toes, like horses and cows) momentarily in ballet performances that rock the theater. The metatarsals allow us to flex our feet to maintain balance, and tarsals which allow us to put our feet on the ground for running for marathons or for running our prey to exhaustion to catch them. We can even manipulate objects with our feet (like cars and sewing machine pedals) so that feet as they are probably won't go away. Nor blue eyes, because the tilt of the Earth won't change much in centuries to come. When Earth's movement changes significantly, we will have much more immediate and imminent problems than evolution.
Birds have had over 200 million years to evolve their bipedalism (theropod dinosaurs arose about 231 million year). Humans have had only about 2-4 million years to evolve our bipedalism. Its only natural that our bodies haven't worked out all the kinks yet
you inherited those issues from your diet, not your genes. stop eating the plant slop your grandparents did and you'll stop having the health problems they had. simple.
It’s interesting bringing up genetic drift and bottleneck considering humans were reduced to insanely low numbers after the eruption of Toba 70,000 years ago.
There's mounting evidence in the last decade or so that Toba did not cause a bottleneck, and the hypothesis has lost favor. There is however evidence of an event that reduced genetic diversity in ancestors of modern humans around 800-900 thousand years ago by up to 99 percent.
More intreaging is the fact every human alive today is related geneticly to a male and a female 90000 years apart. Saw a study of a dna test on an egyptian mummy that found it had dna frim individuals 300000 years earler and mummy not related to us at all. Which bags the question at what point in history did we become the sole inheritors of two sers of genes from two individuals and what happened to the rest of the individuals dna that disapeared in our current population

I loved everything about this documentary. From the narrator, to the ideology, to the way it was shot, and presented it does an exemplary job of making a complex and taboo subject seem obvious. A lot of research went into the making of this and I'm super- impressed by it.
With the invention of the microchip, allowing the human brain to interact with technology, i think its most likely we will see leaps and bounds in bionics. Bionical limbs, eyes, ears etc, curing all the major disadvantages from being deaf, blind or missing limbs. Changing our dna to create the perfect human would take much longer.
Our bodies are marvelous. Compared to most other animals we are large and strong, we have quick reflexes and can throw objects at great velocity. We can outpace most animals and have a very long lifespan. And that isn't even mentioning our intelligence
Humans are the ultimate glass cannon build. What we’re good at, we’re phenomenal at. Then what we’re bad at, we’re horrible at. Truly such a niche evolutionary build. Another thing to consider is our form is so recent on ontological timescales, that we haven’t had the time to really flesh out our form. Maybe we’ll ascend from glass cannon to a highly polished jack of all trades. Such as alligators, crocs, and scorpions who possess genetic traits we can only dream of having. Immunity to cancer, limb regeneration, overall genetic heart disease resistance, more efficient metabolisms, higher heat and cold resistance, etc..
I agree. As a species it doesn’t matter if some don’t live to old age or are sick, as a race we have been incredibly successful due to brilliant design. After humans manage to engineer something so intelligent, self-repairing, dexterous, self sufficient which can reproduce, we can criticize the design of the human body. But I’d bet the farm that we will never achieve that.
We really aren't strong, other animals of our size are stronger. We don't have better reflexes than most other mammals, we aren't really that fast in general, and it is only our advances in tech that gave us a long lifespan. Also, a huge number of other animals can see, smell, or hear better than us.
Comparing animals perfection misses the whole point of evolution. “Fit” doesn’t mean great abs, it means fits in with environment, or you could say cockroaches are superior to you.
I men, look at the African elephants. Their ancestors, the entire taxonomic group _Elephantoidea,_ evolved in a much wetter Ancient Africa to live in swamps and wetlands and to feed on softer plant matter, with their teeth cusps and enamel later adapting to harder grasses. Now they're stuck in African grasslands, veldts, deserts, and occasionally the rainforest, with thin nearly hairless skin they need to cool cool and protected from sunburn and insects by caking it with mud or dust. With soft foot pads once useful to tread on soft swampy ground, now adapted to walking on shifting sands. The wrinkles and creases in the skin trapping water and helping in thermoregulation. Prehensile nose trucks evolved to act as snorkels, now used to suck up water and spray it into their mouths. Large ears used to regulate body temperature and wave away insects. Tusks originally used to shear off vegetation, now used to dig up the ground (and in defense). And the modern elephant's digestive system and its symbiotic gut bacteria are terribly ineffective at digesting hard dry grasses, as they are not ruminants, have no multiple stomachs (unlike cattle). But they persists. You don't have to be "perfect", only good enough to survive from generation to generation.
Regarding the feet problems mentioned in 24:30: TBF majority of those issues are actually a result of the garbage SHOES we wear. Gumans have been running around after animals for hundreds of thousands of years, and while we have fossils of cavities, cancer, murder, and other things, the one thing we have yet to find is stress fractures or things like bunions on fossilized human remains. In fact, those things seem to have appeared very recently, with the invention of pointy shoes and heels. It's almost like squeezing your foot into something too tight for it is a bad idea. Foot cramps and stuff can be solved very easily by switching to minimalist shoes, which have a wide toebox spacious enough to let your toes spread apart, which is used to absorb shock. Also: Humans are plantigrade bipedals BECAUSE we lack tails. Need a wide base for balance. Also, one of the best features of women wouldn't exist if we still had tails, because the gluteus maximus is anchored to the tail bone, and is EXTREMELY important in maintaining balance. Likely without that muscle we wouldn't be able to stand upright. Finally, editing to add this: While humans WALK plantigrade, when running you should really aim to run digitigrade, since it helps to distribute the impact from landing on a larger surface, and helps save energy while running.
Modern shoe design traces back to the late 1,600's where some royalty had their footwear taper to a pointed toe, and so the populace followed along to emulate, and so it's been that way since... (OUCH!)
This is true, we walk plantigrade but you should run digitigrade. I've notice people who run plantigrade end up with knee and ankle problems later in life because slamming your weight onto your heel creates a large sudden shock throughout your joints. If you run using the balls of your feet the shock is spread and absorbed much better throughout the leg.
also wasnt that study on human brain shrinkage proven to have been incorrect? like the claims they made were only supported by a fraction of the skulls they found?
@@carlosangui7490 Yes. Shitty running form(IE heel striking) and garbage diet practically guarantee stress fractures by the time you're thirty. Also way more common in women, who already have a lower bone density compared to men.
Our bodies are not badly or well “designed”. They are the products of a very long, incrementally improving but blind process. A process that has no goal or endgame.
@@burnburn645 yes for individuals in each generation. But there is no long term goal that evolution is directed at. A beneficial mutation may make an individual have more offspring. But that is not evolution, as evolution does not work at the level of the individual. At its basic level, evolution is the change in allele frequencies of a population, over time. That is an unguided and blind process.

Yeah, it's kind of like having our breathing and swallowing tubes in the same area. That same thought actually caused me to lose my faith in the Catholic God, or any God for that matter, when I was 11. If we're built in "his" image, why are there so many flaws in the design? Science may not give us all the answers yet, but it's humble enough to constantly correct mistakes and evolve with time.
"Yeah, it's kind of like having our breathing and swallowing tubes in the same area." Lots of animals have the same design. But while in that vein, consider the short distance between the female Paradise and the Dump, if you know what I mean....

If we are God's most important creation, why did he make us so anatomically flawed and prone to suffering? The idea that we only get diseases and complications purely because of our lifestyle is a delusional one. No matter how you live, no matter how healthily, the chance of cancer is never 0, and that's a design flaw. God isn't real.
Evolution seems to go with "good enough." Or, "did you die?" Nature seems to "care" very little about optimal design, so a lot of adaptions seem poorly designed, but they were good enough to allow humans (and other species) to survive nevertheless.
There is a difference between thriving and surviving. Much of the dna that allows us to survive is hard-coded and does not change (for example hunger, thirst, lust are all engrained into our dna and never change). What caused us to survive so long is those instincts along with the development of our brains. The brain was a cheat code and is all that is needed along with the hard-coded survival instincts so that we survive regardless of evolution. All traits that humans developed afterwords were all pretty unessasary and beauty related to motivate reproduction. Humans could have devolved claws, and large molars..but that was not needed to survive. Brain is all that is needed, and all evolution that occurred since there was to promote Beaty for the most part. Now our adaptations have been focused on our wants not needs so surviving has always been easy but the question is thriving?
I'm tired of the whole "human anatomy's ass" thing, you're not meant to strike the ground with your heel, you're not meant to eat doritos and drink coke, you're not meant to birth with your legs up in the air, you're not meant to pull all nighters... It's akin to press the "start" button on the computer, cleaning it soapy water and drying it with sand paper and then wondering why it breaks so fast. Why doesn't anyone stop and think "maybe, just maybe, we are not using this thing the way it's meant to be, maybe we're not keeping it the right way"?
What if... it's simply not profitable? What's the incentive to not sell Coke when you can sell Coke Zero? Who's going to buy Red Bull if nobody pulls all-nighters? We strike the ground with our heel probably because of shoe design (shoes protect our feet!) - and the shoes made with thinner soles that encourage running on the balls of our feet wear out too fast to be practical. Also, CHAIRS WITH LUMBAR SUPPORT. No you're not meant to sit still for hours on end, but chair technology enables us. Technology seems to be evolving too fast for our anatomy to catch up to. Meanwhile, at this exponential rate, artificial intelligence might just figure out how medically alter our genes for optimal performance in whatever environment we find ourselves in...
Even with that, the point still stands. Tell me, will a shredded leaf become a full healthy leaf if you use it right? No, it won't. Even if we use our bodies right, there are still things that are not efficient enough, not good enough, and not useful enough. You can't make something perfect if it is imperfect.

I was just about to mention trade-offs but it was mentioned in the video. The trade off is what matters most and that’s why the word perfect should never be used when discussing evolution. How on earth would anyone know what perfect means in an environment that changes over long periods of time? What may have worked at one time simply can’t work now. A great example of this is obesity.
46:29 There is evidence out there that our modern diet is causing the jaw to develop less as we grow up. Something to do with the type of protein and calcium in our diet (eat more eggs while young). Since people will just get dental surgery, and dental issues are not a leading cause of death, there is no selection pressure on jaw size currently. In fact, leading causes of death before passing on your genes (having kids) are accidents, heart disease and suicide. So there are selection pressures against risk takers, poor cardio vascular health, those with poor social networks. So base on the pressures: Humans in the future will be more risk averse, have lower incidence of heart health issues, and are more drawn to socialize with others.
@@ScorpioSunset-ux8mv More socializing is more risk taking? Do you have knife fights with your friends? lol The underlying skill for socializing is forming a 'model of mind' of the other person. Basically, your goals and thoughts dont need to match with the other's. Those who are better in that, will be better able to maintain close friendships and connections. Having a strong support network is the strongest defense against suicide. Additionally, risk taking comes largely from judgement. Whats the risk of you falling from this action? Can you run this red light? Its this object safe to play with? The risk takers in traffic or with extreme sports, are those preferring to do dangerous work - are at a greater risk of dying, leaving us to survive and reproduce.
This has to be the best rundown of how evolution works to solve the current problems that animals and plants face, all in the name of survive or die. It really does beg the question of how far we as a species among many others will adapt to the environment while challenging our current health and environmental issues.
One change will likely be narrower pelvises in women. In the past a woman whose hips were too narrow for the child to be born just died in childbirth. So did the child, of course, so the narrow-hipped genes were not passed on. Now they would just have a cesaerian section, so any random narrow-hipped genes that arise in the population do get passed on. Over time more and more women will need caesarians. Modern medicine and other technologies radically reduce the eveolutionary pressures that kept us fit in the past. No one dies of anything much these days except old age. I wonder how many other incidences of such adverse genetic drift will take place due to modern technology? Or maybe we will fix them with genetic manipulation in the future. Who knows where that will finish up.
Idk, man. We forget sexual selection. It’s as the peacock, humans themselves will look for attractive features such as defined jaws, wide hips, full head of hair, beards, height, etc. I wouldn’t rule out things such as that.

Eating was more raw back in the day and needed more bacteria/enzymes for digestion. Now, it is not really an issue but still has a function hence why we have it still.
I never deloped wisdom teeth. Dentist told me that I must be among the very few who already carry the genetic change that more in the future will also have, that will exile wisdom teeth.
That's one way to go. Mine went the other way, I almost had enough room for my wisdom teeth to come in without adjustments, but I had one that just barely couldn't do it...

How anyone thinks humans were "intelligently designed" just goes to show how little people actually think. We've never been more informed ever in history than right now and yet bronze age ignorance thrives. I gave up trying to argue with them for a few reasons but the biggest one is that they arrived at their beliefs by emotions not facts. Facts will never deconstruct those feelings.
I could accept “not all that intelligent design” or “deliberately faulty design just to screw with you”, but intelligent design just doesn’t sound right. It’s either poorly designed, deliberately faulty designed (like a washing machine designed to break just when the guarantee expires) or (most likely) no design whatsoever.
i’m in constant awe of humanity and you should be too. the odds of our existing in the capacity we do are so impossible that it seems foolish to not expect some great supernatural reason for it. that closed hole you’ve dug for yourself is the same closed hole most religious people are in, both holes dug with hardened minds

Instead of claiming they're supernatural, maybe be a lil more objective. there's 92 elements spread out across billions of galaxies... yah, carbon life pops up from time to time.

I was born 1999, I don’t have wisdom teeth, not event a shadow of them. Everyone else in my family, immediate or more distant, have wisdom teeth that either grew in or got removed. Evolution is happening.
I was also born in '99 and wasn't born with adult back teeth. even got an x-ray at 13 and no adult teeth were seen in the back under my baby teeth. Plus they never fell out to this day. So lucky me. Accept they are visibly more "worn" than my frontal teeth that did fall out.
I had my appendix removed two years ago. I can tell you I feel like my stomach and gi were more robust before it had to go. I didn’t feel as sentitive to eating certain things.

I thought I was the only person who thought that the designer of our bodies made many mistakes putting humans together. I'm sitting here with my lower back and neck aching and my knees have a sharp pain when I move them a particular way or walk too far. I spent more than 50 years exercising daily and to have this happen is frustrating. I enjoyed my early AM exercise routines. I always felt good when I came back. Now I'm wanting to get back out and all I get in the morning is a big backache. This ain't how it should be. Design flaws all over.
Upthread we were told your bad back is because you are "lazy". NEVER MIND that your upright posture and relatively big brain have helped you and billions of other humans to dominate the planet!!! What the cretins who write this kind of nonsense forget is that other animals ALSO have "deficiencies" you might call bad "design". Gazelle's are fast, but they lack teeth to defend themselves against lions. Great Whites are vicious predators, but they're nonearly as smart as Orcas who can and do eat them for lunch. etc.
It's a show of age not bad design I think. From your comment judge you are 60+? For most animals this is way old. We are made of material and that material gives up at some point. It's just the sand of time gnawing on you.

Omg that image was hilarious 🤣
That form was too short-sighted. There’s several ways a body can grow more resistant to physical impact without the need for major structural changes. The wonderful world of science fiction futurism is full of examples of humanoid alien beings with clever adaptations to make them a sturdier humanoid without sacrificing their form. Stuff like titanium-coated bones, which is technically possible with mushrooms that use coal & obsidian to make them more resistant to being eaten by insects. Or the iron snail that’s shell is made out of absorbed iron it eats in its environment. A planet with a higher titanium content might see the rise of species that utilize the abundance to strengthen and reinforce their frame.
Cursed image.
Lmao who needs armor when you can just be a fat orb? It’s hard to move as a fat orb tho so lets live in an enviroment that can support our weight. Oh also lets develope fins and sonar to navigate said enviroment. And now the optimal human design is “whale”. Great

I always thought that our balls having no protection was a bad design flaw. The ability to be taken down by a minor tap on the crotch is such a stupid weakness.
But the survival of the sperm at a temperature difference is more important than getting kicked in the nuts (scientifically speaking)
Not guarding it is stupid.
Almost all mammals have external balls, without a natural defense of them, so logically there must be an overwhelming advantage to external balls, or they wouldn't have been chosen for across most species. My understanding is that the sperm need the temperature difference to be effective at being sperm and fertilizing eggs. Probably the advantage of breeding super successfully overwhelmed the few unfortunate guys that took a random nut shot. Also consider that every male does not need to breed, we just need all the females to get preggers, and a few lucky guys can take care of that, no problem ;) We men are very expendable as a gender, and were much more so in the ancient past, so as long as enough guys survived to adulthood, we could easily lose 10-20 % of males, and still do fine as a species. Also, on most mammals, the crotch is pretty well defended by its position UNDER a quadruped's body, in the rear, but not exposed from the back. On four legs, its pretty hard to take a crotch hit, so we are an unusual evolutionary design, that has less protected balls, to gain running upright and use our hands for tools, and these things are probably far more useful on the ancient plains of Africa than good defensive ball positioning.
Yeah, I think it ends up being a thing to do when how body plans work. Pretty much the fact that balls and ovaries are basically encoded and developed the same to a certain point during gestation makes them very efficient genetically. Only needing a location change some additional genes and hormones makes this way easier from a developmental stand point. It allows A lot more commonality in genetics between male and female.
it's because they work better at a lower temp than your body, so they need to be outside if it without much of a barrier

Fun fact: the strongest selection of beneficial genes takes place up to the age of sexual maturity. Genetic diseases that kill you *after* sexual maturity will already have been passed on to your offspring. That's why so many chronic illnesses hit for the first time in the late teens.
If humans had evolved with sexual maturity not hitting until aged 50, we'd see the majority of people enjoying good health going into our 50s.
What a good idea. We'd make much better partner choices by 50 and have 30 or 40 years to make mistakes without outcomes.
Fun fact: We can do this ourselves by actively choosing to have children later in life. And it'd help with the overpopulation problem killing the planet.
But you forget that that limits the rate at which we can reproduce. One of our evolutionary jumps was a younger sexual maturity relative to our maximum age. And most assuredly got us through some hard evolutionary time. Unfortunately it's one of those traits that is also less beneficial now as even an age into our 20s would make worlds of difference in our mental maturity now.
No. Elder people helps those that are having children. Having healthy grandparents is an advantage.

“The face is almost near beautiful”
* shows us a face not even a mother could love*
There is another possible point to our hair outside of temperature regulation. Our hair knots very easily and just keeps growing to unusual lengths. It will twist and weave itself together by just moving around especially when very curly. And to keep it as orderly and unknoted as we do you need a comb or a brush. Our hands by themselves not being enough to do more than to seperate the hair into seperate knotted bushles. Basically dreadlocks, which may be the oldest hair style of our speciess, and in a way our natural one too.
But what for us today is an annoyance, may have very well been a boon for our ancestors. Because hair is very strong and resilient, when knoted so much it basically becomes felt, it will create extreamly durable and cushioning structures. Likely even increasing the capability to deal with temperature even more, as hair felt is extreamly breathable, can cool when sweat evaporates thrugh it from underneath but also insulate to the heat on the outside. While it also would potected against cuts and blunt impactes. For a species that puts more and more energy into their brain, and uses it as it´s most important tool for survival while also being the most vulnearble placed high above ground and exposed on top. So a head of tightly knotetted hair, will act quite well as natural armour, protecting from cuts by sharp objects or claws and cushining from impacts by fall or running into something. While the ends that wear of and fray away are constantly replaced by our fast and long growing hair from below. Like some dogs, breed to also have fur that grows long and felts to give them a protective coat when used for hunting.
For an animal that has such a need for it´s large yet fragile brain, and that while well protected by the skull is still quite suceptible to blunt impacts, that would be an evolutionary boon.
@theexchipm'k You wrote your comment yourself - BRILLIANT!
Combs were developed due to insect infestations eg Head-lice and ticks. Many people across the world only use their fingers to groom their hair, usually someone else's - this is normal behaviour of most creatures. Grooming strengthens bonds through physical contact between others, family, groups or with inter-species.
Long hair is/was plaited or bunched, which is easier to manage. Adornments were very often added into the plaiting, such as shells, pieces of wood, beads etc...
From England.
I've heard that ancient Egyptian soldiers grew their hair instead of wearing helmets! It's probably not the best solution overall but it could work.
Our bodies are not badly designed, they're badly maintained. Human beings are naturally the greatest endurance runners the world has ever seen, capable of stalking prey a hundred times their size or more for days without stop and taking said prey out with consumate ease.
We're not weak, we're horrifically over powered.
We simply changed our diet, exercise habits and social structures over the course of a mere five thousand years. That's not long enough for us to adapt to a dynamic that is completely opposite of what we have done for the past fifty to one hundred thousand years.
We're not evolved to be sedentary, plant eating animals. We are omnivores but adapted to have the majority of our diet be meat, we're adapted to consume a large carbohydrate intake because we're supposed to be almost constantly in motion.

A note about genetics: six fingers on a hand-as is common in Amish communities-is dominant over a five-fingered hand I don't see five fingers going anywhere ant time soon, and indeed it might be that five fingers is ideal. When you look at certain tools like wrenches, you notice that you need all five fingers to operate them. Two sets of two fingers can give two manipulative pincers while the thumb creates a strong closing grip. Or you can hold two items in one hand and switch back and forth dextrously between them. I've held a pencil and a click eraser in the same hand and switched use without switching tool position.
However, I don't see six fingers going away, any more than the palmeris longus, a throwback trait that is absent in about a quarter of the population. Or even the recurrent laryngeal nerve which takes an unnecessary dip underneath the aorta. It worked well in fishes, but not for us, and certainly not for giraffes in which it is a couple of meters longer than it really needs to be. Unless a trait is pressured against in the environment, it won't go away.
And even the foot -which I malign for its many and fragile bones (can be broken with a good hard stomp) - has an elegance born of its many joints. The toes allow us to become ungulagrade (running on toes, like horses and cows) momentarily in ballet performances that rock the theater. The metatarsals allow us to flex our feet to maintain balance, and tarsals which allow us to put our feet on the ground for running for marathons or for running our prey to exhaustion to catch them. We can even manipulate objects with our feet (like cars and sewing machine pedals) so that feet as they are probably won't go away.
Nor blue eyes, because the tilt of the Earth won't change much in centuries to come. When Earth's movement changes significantly, we will have much more immediate and imminent problems than evolution.
Birds have had over 200 million years to evolve their bipedalism (theropod dinosaurs arose about 231 million year). Humans have had only about 2-4 million years to evolve our bipedalism. Its only natural that our bodies haven't worked out all the kinks yet

It’s interesting bringing up genetic drift and bottleneck considering humans were reduced to insanely low numbers after the eruption of Toba 70,000 years ago.
There's mounting evidence in the last decade or so that Toba did not cause a bottleneck, and the hypothesis has lost favor. There is however evidence of an event that reduced genetic diversity in ancestors of modern humans around 800-900 thousand years ago by up to 99 percent.
Didn’t the black plagues cause a bottleneck in humans?
More intreaging is the fact every human alive today is related geneticly to a male and a female 90000 years apart. Saw a study of a dna test on an egyptian mummy that found it had dna frim individuals 300000 years earler and mummy not related to us at all. Which bags the question at what point in history did we become the sole inheritors of two sers of genes from two individuals and what happened to the rest of the individuals dna that disapeared in our current population

Our bodies are marvelous. Compared to most other animals we are large and strong, we have quick reflexes and can throw objects at great velocity. We can outpace most animals and have a very long lifespan. And that isn't even mentioning our intelligence
Humans are the ultimate glass cannon build. What we’re good at, we’re phenomenal at. Then what we’re bad at, we’re horrible at. Truly such a niche evolutionary build.
Another thing to consider is our form is so recent on ontological timescales, that we haven’t had the time to really flesh out our form. Maybe we’ll ascend from glass cannon to a highly polished jack of all trades. Such as alligators, crocs, and scorpions who possess genetic traits we can only dream of having.
Immunity to cancer, limb regeneration, overall genetic heart disease resistance, more efficient metabolisms, higher heat and cold resistance, etc..
I agree. As a species it doesn’t matter if some don’t live to old age or are sick, as a race we have been incredibly successful due to brilliant design.
After humans manage to engineer something so intelligent, self-repairing, dexterous, self sufficient which can reproduce, we can criticize the design of the human body.
But I’d bet the farm that we will never achieve that.
We really aren't strong, other animals of our size are stronger. We don't have better reflexes than most other mammals, we aren't really that fast in general, and it is only our advances in tech that gave us a long lifespan. Also, a huge number of other animals can see, smell, or hear better than us.
Chimps (our nearest living relatives) are half our size but way stronger than us.
Comparing animals perfection misses the whole point of evolution. “Fit” doesn’t mean great abs, it means fits in with environment, or you could say cockroaches are superior to you.

Answer : Because we're not "designed". We're just a pile of random events/stuff. We're a litteral randomized character...
I men, look at the African elephants. Their ancestors, the entire taxonomic group _Elephantoidea,_ evolved in a much wetter Ancient Africa to live in swamps and wetlands and to feed on softer plant matter, with their teeth cusps and enamel later adapting to harder grasses. Now they're stuck in African grasslands, veldts, deserts, and occasionally the rainforest, with thin nearly hairless skin they need to cool cool and protected from sunburn and insects by caking it with mud or dust. With soft foot pads once useful to tread on soft swampy ground, now adapted to walking on shifting sands. The wrinkles and creases in the skin trapping water and helping in thermoregulation. Prehensile nose trucks evolved to act as snorkels, now used to suck up water and spray it into their mouths. Large ears used to regulate body temperature and wave away insects. Tusks originally used to shear off vegetation, now used to dig up the ground (and in defense). And the modern elephant's digestive system and its symbiotic gut bacteria are terribly ineffective at digesting hard dry grasses, as they are not ruminants, have no multiple stomachs (unlike cattle). But they persists. You don't have to be "perfect", only good enough to survive from generation to generation.
Good answer. We also were probably aquatic, but because the Savannah theory has run rampant, nobody gives it a chance. Pigs were probably aquatic too.
So much to learn in one life time
Regarding the feet problems mentioned in 24:30:
TBF majority of those issues are actually a result of the garbage SHOES we wear.
Gumans have been running around after animals for hundreds of thousands of years, and while we have fossils of cavities, cancer, murder, and other things, the one thing we have yet to find is stress fractures or things like bunions on fossilized human remains.
In fact, those things seem to have appeared very recently, with the invention of pointy shoes and heels.
It's almost like squeezing your foot into something too tight for it is a bad idea.
Foot cramps and stuff can be solved very easily by switching to minimalist shoes, which have a wide toebox spacious enough to let your toes spread apart, which is used to absorb shock.
Also:
Humans are plantigrade bipedals BECAUSE we lack tails.
Need a wide base for balance.
Also, one of the best features of women wouldn't exist if we still had tails, because the gluteus maximus is anchored to the tail bone, and is EXTREMELY important in maintaining balance.
Likely without that muscle we wouldn't be able to stand upright.
Finally, editing to add this:
While humans WALK plantigrade, when running you should really aim to run digitigrade, since it helps to distribute the impact from landing on a larger surface, and helps save energy while running.
Modern shoe design traces back to the late 1,600's where some royalty had their footwear taper to a pointed toe, and so the populace followed along to emulate, and so it's been that way since... (OUCH!)
i ask from the ignorance, do stress fractures exist in non elite sport humans?
This is true, we walk plantigrade but you should run digitigrade.
I've notice people who run plantigrade end up with knee and ankle problems later in life because slamming your weight onto your heel creates a large sudden shock throughout your joints. If you run using the balls of your feet the shock is spread and absorbed much better throughout the leg.
also wasnt that study on human brain shrinkage proven to have been incorrect? like the claims they made were only supported by a fraction of the skulls they found?
@@carlosangui7490
Yes.
Shitty running form(IE heel striking) and garbage diet practically guarantee stress fractures by the time you're thirty.
Also way more common in women, who already have a lower bone density compared to men.
"from the moment I understood the weakness of my flesh, it *disgusted* me"
Our bodies are not badly or well “designed”. They are the products of a very long, incrementally improving but blind process. A process that has no goal or endgame.
maybe, planet earth is but a petri dish.
it most definitely at least has the one goal of propagating / surviving. ;D
@@RockBrentwood "Simplicity is the ultimate sophistication" - If you can't say something with simple words, don't.
@@burnburn645 yes for individuals in each generation. But there is no long term goal that evolution is directed at. A beneficial mutation may make an individual have more offspring. But that is not evolution, as evolution does not work at the level of the individual. At its basic level, evolution is the change in allele frequencies of a population, over time. That is an unguided and blind process.

Yeah, it's kind of like having our breathing and swallowing tubes in the same area. That same thought actually caused me to lose my faith in the Catholic God, or any God for that matter, when I was 11. If we're built in "his" image, why are there so many flaws in the design? Science may not give us all the answers yet, but it's humble enough to constantly correct mistakes and evolve with time.
"Yeah, it's kind of like having our breathing and swallowing tubes in the same area." Lots of animals have the same design. But while in that vein, consider the short distance between the female Paradise and the Dump, if you know what I mean....

Check out human aquatic evolution...it answers many of these problems. VERY interesting!
"Build in His image" means that we look like Him. That doesn't mean that we're perfect. But regarding our bodies, it's our lifestyle, not the anatomy that's mostly at fault.
@@insertname9736Incorrect. If our bodies were perfect, we wouldn't be prone to cancer, HIV, and various other diseases. If our immune system wasn't flawed, we would be able to overcome those things effortlessly, but it's far from the most perfect system in the animal kingdom. If we are God's most important creation, why did he make us so anatomically flawed and prone to suffering? The idea that we only get diseases and complications purely because of our lifestyle is a delusional one. No matter how you live, no matter how healthily, the chance of cancer is never 0, and that's a design flaw. God isn't real.
Evolution seems to go with "good enough." Or, "did you die?" Nature seems to "care" very little about optimal design, so a lot of adaptions seem poorly designed, but they were good enough to allow humans (and other species) to survive nevertheless.
There is a cost benefit ratio, coupled with changing environment.
It did nail things with the shark. Very few redesigns over the course of hundreds of millions of years.
@@mc_zittrer8793 Same with the Dragonfly and several Arthropods. I guess some body plans just work.
There is a difference between thriving and surviving. Much of the dna that allows us to survive is hard-coded and does not change (for example hunger, thirst, lust are all engrained into our dna and never change). What caused us to survive so long is those instincts along with the development of our brains. The brain was a cheat code and is all that is needed along with the hard-coded survival instincts so that we survive regardless of evolution. All traits that humans developed afterwords were all pretty unessasary and beauty related to motivate reproduction.
Humans could have devolved claws, and large molars..but that was not needed to survive. Brain is all that is needed, and all evolution that occurred since there was to promote Beaty for the most part.
Now our adaptations have been focused on our wants not needs so surviving has always been easy but the question is thriving?
Zima blue is one of the greatest short films I’ve ever watched
We're still evolving. Everything is. Our bodies are less badly designed and rather a work in progress.
I'm tired of the whole "human anatomy's ass" thing, you're not meant to strike the ground with your heel, you're not meant to eat doritos and drink coke, you're not meant to birth with your legs up in the air, you're not meant to pull all nighters...
It's akin to press the "start" button on the computer, cleaning it soapy water and drying it with sand paper and then wondering why it breaks so fast.
Why doesn't anyone stop and think "maybe, just maybe, we are not using this thing the way it's meant to be, maybe we're not keeping it the right way"?
What if... it's simply not profitable? What's the incentive to not sell Coke when you can sell Coke Zero? Who's going to buy Red Bull if nobody pulls all-nighters?
We strike the ground with our heel probably because of shoe design (shoes protect our feet!) - and the shoes made with thinner soles that encourage running on the balls of our feet wear out too fast to be practical. Also, CHAIRS WITH LUMBAR SUPPORT. No you're not meant to sit still for hours on end, but chair technology enables us.
Technology seems to be evolving too fast for our anatomy to catch up to. Meanwhile, at this exponential rate, artificial intelligence might just figure out how medically alter our genes for optimal performance in whatever environment we find ourselves in...
So real
Why why do you think it is that average life spans so much longer today than they’ve been historically?
Even with that, the point still stands.
Tell me, will a shredded leaf become a full healthy leaf if you use it right? No, it won't. Even if we use our bodies right, there are still things that are not efficient enough, not good enough, and not useful enough.
You can't make something perfect if it is imperfect.

I was just about to mention trade-offs but it was mentioned in the video. The trade off is what matters most and that’s why the word perfect should never be used when discussing evolution.

46:29 There is evidence out there that our modern diet is causing the jaw to develop less as we grow up. Something to do with the type of protein and calcium in our diet (eat more eggs while young).
Since people will just get dental surgery, and dental issues are not a leading cause of death, there is no selection pressure on jaw size currently.
In fact, leading causes of death before passing on your genes (having kids) are accidents, heart disease and suicide.
So there are selection pressures against risk takers, poor cardio vascular health, those with poor social networks.
So base on the pressures:
Humans in the future will be more risk averse, have lower incidence of heart health issues, and are more drawn to socialize with others.
There's a contradiction because mpre socializing = more risk taking.
@@ScorpioSunset-ux8mv maybe they'll take the risks but be able to minimize it / react better?
@@ScorpioSunset-ux8mv more risk of strengthening your immune system that way.
@@ScorpioSunset-ux8mv More socializing is more risk taking? Do you have knife fights with your friends? lol
The underlying skill for socializing is forming a 'model of mind' of the other person. Basically, your goals and thoughts dont need to match with the other's. Those who are better in that, will be better able to maintain close friendships and connections.
Having a strong support network is the strongest defense against suicide.
Additionally, risk taking comes largely from judgement. Whats the risk of you falling from this action? Can you run this red light? Its this object safe to play with?
The risk takers in traffic or with extreme sports, are those preferring to do dangerous work - are at a greater risk of dying, leaving us to survive and reproduce.

One change will likely be narrower pelvises in women. In the past a woman whose hips were too narrow for the child to be born just died in childbirth. So did the child, of course, so the narrow-hipped genes were not passed on. Now they would just have a cesaerian section, so any random narrow-hipped genes that arise in the population do get passed on. Over time more and more women will need caesarians. Modern medicine and other technologies radically reduce the eveolutionary pressures that kept us fit in the past. No one dies of anything much these days except old age. I wonder how many other incidences of such adverse genetic drift will take place due to modern technology? Or maybe we will fix them with genetic manipulation in the future. Who knows where that will finish up.
Genetic manipulation is the key here,we will be able to perfect our vessels.

How anyone thinks humans were "intelligently designed" just goes to show how little people actually think. We've never been more informed ever in history than right now and yet bronze age ignorance thrives. I gave up trying to argue with them for a few reasons but the biggest one is that they arrived at their beliefs by emotions not facts. Facts will never deconstruct those feelings.
I could accept “not all that intelligent design” or “deliberately faulty design just to screw with you”, but intelligent design just doesn’t sound right. It’s either poorly designed, deliberately faulty designed (like a washing machine designed to break just when the guarantee expires) or (most likely) no design whatsoever.
