      Their genetics have sacrificed nearly every aspect of basic resiliency for maximum speed on the plains. Most of the work caring for horses is keeping them from accidentally killing themselves. Full disclosure: I worked as a stable hand as a child in exchange for riding lessons. Will never ever own a horse.

        To add on why broken legs are fatal: its because horses are so big, that even with a sling, they cannot support themselves well on 3 legs. And lying down is also not an option as their own weight will crush their internal organs if they stay down for too long.

          Also, don’t they need to run to move food through their digestive tract? Or to force themselves to cough if they have something stuck in their lungs? I think there is some sort of dependency of basic functions that relies on the movement of their lungs/stomach going back and forth while running that they can’t easily do if they just stand in one place all day

            It’s not just horses, all large mammals have this problem from lying down too long. Horses can and do lie down every day, but for short periods of time. It’s the extended lying down from illness or injury that kills them.

              do humans count as large mammals? pretty sure we have at least very similar problems if we lie down for ages, hence why people who are bed bound have to be moved around regularly.

                You mean bedsores, yeah its a pretty similar cause. The difference is that bedsores only cause damage to the skin from lack of blood flow caused by the extended pressure from lying down. While in horses, the extended pressure from lying down leads to poor blood flow in not just the skin, but the muscles and organs nearby too.

                And yes, you can turn horses over too, but it takes multiple people and is really dangerous to everyone involved, so its not an action to be taken lightly.

        Humans have multiple toes because our ape ancestors used their toes like fingers. Having multiple, separate toes is probably bad for survival unless you’re using toes to manipulate tools.

        Animals that have distinct toes include apes, geckos, mice, raccoons and similar animals which need them to grip onto surfaces or to manipulate things. There are predators which have separate toes because they’re a place to mount claws: eagles, cats, etc. There are animals that have separate toes with webbing between for swimming. But, for a lot of animals, separate toes aren’t really useful, so they’ve evolved away: elephants, rhinos, giraffes, horses, cows, etc.

          Yeah, but at least most of those still have multiple toes to spread the weight around. Horses decided to get rid of that completely.

            Spreading the weight around using toes doesn’t seem to be a useful strategy. It’s also not something that humans do. Human toes are not at the weight-bearing part of the foot. And, while I’m sure toes are somewhat involved in agility, having individual toes doesn’t seem to be. In fact, if you look at apes like gorillas and chimps, it’s pretty clear that our toes have been getting shorter and less important as we’ve been evolving as upright-walking creatures who don’t live in trees. Instead, the sole of the foot, which used to be much more like the palm of a hand, has been getting longer and sturdier.

            If you have separate toes, you have multiple fragile things that can break or be torn off. If you have one mega-toe it’s going to be sturdy. That’s probably why the heaviest animals have the fewest / smallest toes.

              As someone who goes barefoot whenever possible, i can tell you that the idea of toes not being particularly useful for agility is very incorrect. If i have to restrict my toes i feel like dogs do when you put booties on their paws, so incredibly clumsy.

              The toes play a large part in keeping your balance, making minor corrections to your weight distribution, and especially the big toe is pretty significant when pushing off the ground.
              Try walking (or even running) around with your toes lifted off the ground, it’s very awkward.

              The problem is that a lot of people these days are constantly wearing shoes that make their toes useless, and even when not wearing such shoes their toes have been squeezed into a pointy shape (bunions are almost entirely caused by this) and become weak from atrophy. A healthy foot has toes splayed quite wide and the toes will be pretty strong and probably a lot thicker than you’re used to, look at baby feet for a rough example.

                I mostly go barefoot too, and the shoes I have are “barefoot shoes” that have extremely thin soles. But, I still don’t think the individual toes are that important to grip. Sure, the toe pads are important. If you’re moving on the balls of your feet, I’d guess maybe 30% of your weight is in your toes. But, I don’t think I’m getting much contribution to agility from my baby toe being splayed out. If I glued my toes together, I think it wouldn’t hurt my agility much, and it would mean I’m much less likely to catch that individual, fragile baby toe on a corner.

    Its only a valve. Topologically speaking, the passage from the mouth to the anus only constitutes one hole.

    The passage of air into the lungs is not a hole however, that is a cavity. Same difference with the vagina, that’s not a hole, that’s a cavity.

      Depends on the state of your esophagus, doesn’t it? If it’s closed (which it mostly is) then your mouth and nose holes go to your lung cavity. Your anus is also part of a cavity that goes through your intestines all the way up your throat and stops at your esophagus.

            Nose is two. Your butt isn’t one. Or rather, your mouth and nostrils would be the entrance and your butt is the combined exit of those three holes. If you don’t count the nostrils, you only have one hole. A hole always goes through something, otherwise it’s just a cavity. And also, holes only count from one side. Your butt and mouth are the same hole, just from different ends.

              Nose is only one hole homie, runs from one nostril to the other. It takes the mouth to add a secondary orifilce. And it takes the anus to add a third orifice.

                Doesn’t matter which way you turn it, the result is the same. As you count it, your first hole is nostril to nostril. I count mouth to anus as hole one and then add the left and right nostrils as secondary and tertiary orifices. Having a nose ads two holes to the total count. If you had no nose, you‘d have one hole, if you only had a nose, you’d also only have one hole.

              Important note, if you take a straw that separates into two split straws (kinda in a “Y” shape) that from a topological point of view is two holes, because one is for one of these paths, and the other is an extruded hole on the side of the first path. In topology you can’t break or mend material, but you can pull, stretch, squeeze and move it all you want. So you can move one of the split straw “legs” to the bottom of the whole straw, getting a shape similar to a “V”, it would look pretty much like a pair of pants. And topologically speaking it would be exactly the same. So… One straight hole for your mouth all the way down to your anus. Another two are there for your nostrils, that’s 3 already. The rest are for your tear ducts, which have two holes on the edge of your eye, (so four in total) which merge and then connect to your nose.

              So a human, from a topological perspective, is just a seven holed doughnut. Also Vsauce made a great video about that, with pretty great animations.

          I am well aware that people have three topological holes. Matter of fact, I proved that years ago.

          In this case, I only referred to one topological hole, from mouth to anus.

          I never mentioned the nose, nor was that part of the topic in question.

      You could still probably blow with your mouth if you didn’t have your lungs connected, I imagine it would involve a kind of burping type of action. I think the bigger problem would be that if your nostrils closed up, you wouldn’t be able to breathe, and probably also talking would be a lot harder if your vocal chords and mouth were separate from your main air sacs.

      I think the solution is probably just an easily opened and closed internal valve that separates the stomach and the lungs, rather than this bullshit we currently have with two separate valves that lead into both and open for one and then close for the other whenever it’s required. It’s still good to be able to close both when you want to, but you can already close your mouth on command, and another valve with the nose is a notable upgrade in that it keeps everyone from smelling bad smells they don’t wanna smell, and it also doesn’t take any more valves than we already have.

      There’s probably some way you could fix this all with enough surgical intervention, I bet…

    Horses were at least marginally less ridiculous before people got involved. Not quite to the same extent as dogs, but compare a steppe horse with a thoroughbred and you’ll see that they’re smaller and hardier. Much better equipped to live, slightly less able to carry fully armored people on their back.

          I feel like if that happened with a human it would be a pretty minor thing to go up in there and smash the egg so you just shit out the shell and stuff. I don’t really see a reason it would have to be fatal, or even really all that big of a deal, if that’s just what human reproduction looks like.

          Now if we were using the cloaca in the same way we presently use the vagina, as a birth canal for developed offspring, that would be a different story, but ultimately not all that different from now.

      From an evolutionary standpoint we just have to survive long enough to reproduce, if we can’t eat past age of reproduction there’s no evolutionary pressure to change that.

        That’s completely untrue.

        Evolution applies to the entire lifespan — if we could “reproduce” but died in childbirth every time, our species would have gone extinct long ago.

        Parents and grandparents also contribute greatly to the success of a child long long after they’re born, helping to ensure it also survives to reproductive age.

            I don’t disagree with your overall point, but statistics like that are almost always heavily skewed because of high infant mortality rates

              The mortality rate during childbirth was pretty high for women on top of the infant rate. Childbirth as a whole dragged the numbers down.

                  The domestication of storks has also led to fewer deaths upon delivery. I wish to also add something to this thread of reddit factoids.

            A reminder that life expectancy in ancient history was so low not because people generally croaked by 40, but because of how many children died young.

            It’s an average, not a maximum. People regularly lived into their 70s and 80s hundreds of years ago.

              From what i’ve read and heard about the subject, the life expectancy generally looked something like this back in the hunter-gatherer days:

              You were very likely to die as an infant, pretty likely to die before puberty, after that you were likely to make it to 40-50, and it wasn’t that rare to reach 70.

            [Edit : It turns out people have said the same thing while I was looking for the right source to confirm my point, so I guess this comment’s a bit redundant now. Still leaving it in case someone’s interested]

            The number’s correct but…

            Child mortality The most significant difference between historical mortality rates and modern figures is that child and infant mortality was so high in pre-industrial times; before the introduction of vaccination, water treatment, and other medical knowledge or technologies, women would have around seven children throughout their lifetime, but around half of these would not make it to adulthood. Accurate, historical figures for infant mortality are difficult to ascertain, as it was so prevalent, it took place in the home, and was rarely recorded in censuses; however, figures from this source suggest that the rate was around 300 deaths per 1,000 live births in some years, meaning that almost one in three infants did not make it to their first birthday in certain periods. For those who survived to adolescence, they could expect to live into their forties or fifties on average.

            So reaching 50 wasn’t too rare for someone who had survived childhood, and given how people often started having children younger then, that was well enough to be grandparent. Doesn’t mean everyone would’ve gotten to known their grandparents, but it wouldn’t have been super rare either.

        Generally sure. We’ve certainly evolved to want to be around for a while after reproduction though, for example human infants are completely worthless. That doesn’t mean we need to be top notch, but we do need to exist sufficiently to get children to even the most brutal, basic independence.

        Compare that to something that hatches then is already just adulting, like many reptiles.

        I think the keyword is precocial vs altricial

          Especially considering how reliant we humans are on knowledge, without the previous generation teaching us we’re pretty well doomed.

          Old people would have been highly valued just because they’re sitting on decades of knowledge and wisdom, in an age without permanent records of information grandma would have been the only source of information about the past, and would presumably spend most of their time just sharing that knowledge with everyone else.

          It’s not the sugar, but the acid that our teeth can’t handle.

          The fact that healthy foods can’t be consumed without a risk of harm is not an intelligent design.

          I mean, even apples (i.e. “Garden of Eden”) can promote the growth of plaque!

            Meat doesn’t damage your teeth

            Incidentally the damage from sugar is fermentation - it makes carbonic acid (the stuff that makes soda fizzy) which is a weaker acid than citric

            Citrus didn’t make it to Europe quickly - it came from China

              You are right, it’s just that in Spanish a “pomelo” is a grapefruit, and I was unaware of the whole rabbit hole that is the hybridwtion of the pomelo, mandarin, citrus and all that. I deleted my old comment because I was just confused.
