Why Is Our Skeleton On the Inside?

[@besmart]

Why do some animals have exoskeletons and some have internal skeletons? This question popped into my head one day and the answer turned out to be more interesting than I could have imagined. Skeletons are amazing. Let me know what you thought of the video! I'm on Twitter & Instagram @DrJoeHanson @okaytobesmart

I actually recall hearing from my Vertebrate Zoology professor that the exoskeletons of ancient vertebrates may actually have mainly functioned as calcium sinks to allow for calcium use in cellular functions, and it became repurposed for skeletal functions, which is pretty cool. Also, vertebrates aren't the only animals who turned inside out like this. Keepers of pet birds may recall the cuttlebones sometimes given to them in their cages. Apparently those internal "bones" cuttlefish have are actually the equivalent of the shells of nautilus/ammonites, so cephalopods put their shells on the inside as well. I've even heard of some cephalopod species which use these internal shells as muscle attachments, meaning they actually do have skeletal bones (albeit very few of them), which is pretty neat.

[@ShadeAKAhayate]

You understand that almost everything inside an animal was repurposed at some point, right? Maybe the genetic code mechanism itself wasn't, but that's close to it.

[@watchrocksgrow]

Could a man-sized ant really lift a car? Relative strength decreases with increasing size. Classic scaling issue in biology. The force produced by a tissue is generally proportional to the cross-sectional area of the tissue (pi-r-squared), whereas the mass of the same tissue is proportional to its volume (pi-r-cubed). Basically as you scale up your strength-to-weight ratio gets worse and worse. We'll have to watch an ant fight a tiny man to be sure.

[@dimaswitanto2994]

Facts: -as we scale up our system scale up and our basic force scale up -there's no strength to weight ratio if your Body and those on it gets Bigger to -Basically STo'W ratio is used in athletics stuff for gymnastics and bodybuilding -we used Gravity and force physics for calculating something like building a plane that can withstand certain weight without its engine and its force energy popped out What is "cross-sectiona area"? And those (pir-r-square / pir-r-cubed stuff) you talking about? Please explain

[@aidenfielding9709]

@@dimaswitanto2994 Suppose that we scaled up an insect by a factor of 100. The legs would have a diameter 100 times that of the original and a cross sectional area 100*100 = 10,000 times the original. But, the volume of the animal's body would be 100*100*100 = one million times the original volume. If the tissue and exoskeleton were exactly of the same composition, and thus density, the larger insect would weigh one million times as much as the original. But, the weight of the body would be supported on legs with only 10,000 times as much cross sectional area, and thus total strength, as the original. The weight supported per square millimeter of cross sectional area would have increased by 100 times. The pressure on each millimeter of cross sectional area would have increased by 100 times, the resulting force would crush the animals legs

[@steve25782]

Small things benefit from the square-cube law: We could lift much more relative to our weight if we were scaled down to bug size. Muscle strength is proportional to the muscle's cross-sectional area, a square, while weight is proportional to volume, a cube. So scaling every dimension down by a factor of 2 makes the strength a quarter as much, but the weight an eighth as much, so the power-to-weight ratio doubles. This is why gymnasts tend to be small people and why little kids seem so energetic. :-)

They say smarter brains developed because of diet. Maybe because of vertebrates increase mobility it allowed access do different foods/minerals/vitamins that aided in brain development. 2 ocean dwelling creatures the Dolphin (vertebrate) versus something like a crab (invertebrate). Because of how slow a crab is it can’t really chase a fish, so it instead eats sea floor garbage. But a Dolphin can be fast and catch more nutritious food. Just my thought process tho.

That would be interesting. It's a trope in sci-fi that humans build A.I/androids with metal skeletons. Hey, create in thy own image. I don't think we would be as flexible and perhaps more heavier, as hypothesized in the video, 'What You Changed Your Bones To Metal.' Also, the most current development is titanium foam where it's light and structurally perforated to allow blood vessels to develop inside its interiors - like an actual bone. It's still in its infancy stages, but it may help to replace brittle or irrepairable bones in the future. The brand is InnoTERE.

[@xanhfei]

So its internal exoskeleton?

[@LETSROCKTA]

Thing to note: it is not merely a problem of skeleton vs exoskeleton. Insects and smaller/lighter animals can lift so much more than their weight/ jump higher than their height because of how gravity works. The heavier the mass of an object the more it is « pulled » by gravity. If we were the same size as ants chances are we’d be able pull objects just the way they do.

[@binguser344]

Exactly I hate it when education channels scale up small animals abilities without accounting for gravity

[@LecherousLizard]

That's not how gravity works. Gravity is a characteristic of space and works on everything evenly. The higher the mass, the higher the energy needed to move it, therefore you need that much more energy to stop something from moving. And this plays into a completely different mechanic: drag. Drag is the force a medium _(like air)_ exerts against a moving object. Drag depends on the shape of an object, its mass, speed and the density of a medium. Most insects like ants or beetles are mostly spherical and a sphere creates quite a lot of drag _(sphere has a coefficient of ~0.5 compared to a coefficient of ~0.02 for a tear-like object, think of a wing but top-down symmetric, or ~2.0 for a thin, flat object like a feather),_ so just their shape gives them a lot of drag and then comes their miniscule mass. This leads to an ant's terminal velocity, i.e. the maximum free-falling speed an object can have, of only ~6.5 km/h. For a human that's about the speed of a slow jog or a power walk. For comparison a human in a "free fall" position has terminal velocity of ~200 km/h. And no, we wouldn't be able to lift objects as heavy as ants or other insects, if we were their size. Endo- and exoskeletons perform vastly different depending on the scale. Not to mention chitin "bones" are usually much more flexible than calcium-based ones, so you would be able to lift heavier objects without worrying your bones would break just based on this fact alone.

[@simplyperspicacity]

What 😂😂😂 I don't think you understand have gravity works

[@extraterrestrial7424]

The heavier the object is, the more it is pulled by gravity - well, that's exactly why it is heavier. Bigger mass = more pulled by gravity = heavier. And this relation is linear. More mass = more weight, on a linear scale. So if we were the mass of ants, we would still be able to lift the same percentage of our own weight. Gravity has nothing to do with this.

Not all vertebrates have 4 or 0 limbs, even if you discount stuff like whales and fish. there's the sirens- sirenidae, a group of salamanders with two front "arms" but no back limbs images.app.goo.gl/GoG5E5Tj6HzbhCwE8 The now extinct moa of New Zealand, a large flightless bird, also seemed to have only two legs, but no wings whatsoever. en.m.wikipedia.org/wiki/Moa The modern emu has basically no wings either As to the reason, it's not just 4 limbs, it's also 5 "fingers" on every limb- so called "pentadactyl limbs"- vertebrates evolved from an animal with 4 limbs, each with five sets of bones in them, and everything has followed that pattern pretty much, or some symmetric subset of it

I learned in an insect class in college that insects can't get huge because of internal water transference. That's why insects are their biggest in rainforests...because of all the humidity in the air. The reason why we don't have bones on the outside is related to that. So there's a reason that we have bones on the inside and we wouldn't be here like this without it. We'd be super small otherwise ;-)

[@petersmythe6462]

Re: tiny bugs being able to lift hundreds of times their weight. Ok. And if they only would build cars like hot wheels they would survive having a building dropped on them... Or not. You see, size matters. Being half the size means your muscles are 1/4th the area but you have 1/8th the mass. Likewise, if you scale up an ant 100 times, it'll be 10000 times stronger but 1000000 times heavier. Ergo, unable to lift it's own weight, much less a semi truck.

It's worth pointing out that a big part of why insects are such great lifters is because they're so tiny. Mass is proportional to the cube of length, obviously, but since strength depends on the thickness of one's muscle equivalent but not its length, it is proportional to the _square_ of length. If you scales a beetle up to human size, it wouldn't be able to lift a thousand times its weight (even ignoring the fact that it would suffocate and otherwise die from bad anatomy scaling). On the other side, if a beetle-sized human didn't die from its own set of anatomy scaling problems, they would be a lot stronger, gram for gram.
