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
There’s actually some turtles that can flip over again by just tugging everything in, and because of the form of their shell and the weight distribution they flip back on their feet. Pretty amazing ^^
Yeah as soon as he said that I thought “well they (strongmen) can do that?” although fully loaded might be heavier and all, but still, pull is a bad term here as the forces required are vastly different
Not necessarily so in regards to permanent damage. You'd just have to have new armour plating growing under the old and shed said plates when the new ones are fully developed
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.
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
@@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
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.
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.

And then there's the pangolin, who basically said: "Screw this fur thing, I'm gonna evolve keratin scales all over my body until I look like a goddamned dragon. That way I'll have bones _and_ biological armor."
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.
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.
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.
Endoskeleton have their own perks, Exoskeleton have their own perks.. why not MesoSkeleton? Skeleton on both inside and outside! That would make us invincible!
Exoskeletons peaked at horseshoe crabs. Like it was made so well that they're still around today. Horseshoe crabs are the go pros of the far prehistoric era

I think its better this way, with our brains we can build suits/armor that imitate exoskeletons for multiple purposes. All we're really missing is hybridization with our bodies. To maximize on "hydraulic" performance for the suit. However. It is interesting that the opposite would be 100x harder to achieve, reinforcing bones or adding them into an existing exoskeleton would give little to no benefits.

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.
In my opinion its the size issue again, for a bigger brain u need more space and to get that space without being called bighead u need to grow, but their breathing system is less efficient, so they dont grow to that sizes and so their brain also doesnt grow. Its 6am(havent slept), so forgive if wat i am saying sounds like nonsense
@timk8869 false modifications of organs from external pressures like in the 5 largest insect species and coconut crabs show that's false. They use stream lined designs just like vertebrates.
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.
Actually, that can happen to you, if you ingest strontium(the element below calcium) your body will confuse it for calcium and use it to build the bones, tho it isn't healthy as it has different properties, and your body can't clear it out afterwards, and if it builds up, well you're kinda screwed
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. :-)
Stephen Brackin ya its really simple math, and honestly i dont think exoskeletons would have mattered, even if we didnt have them if we were small we could still be strong many times our weight
“brb bro gonna put my Skelton on the outside so I get stronger” Last online 6 years ago “Aight bro I done it let’s play some minecraft I wanna go collect some roses”
I remember a long time ago that there was a type of fish that had both an endoskeleton and an exoskeleton. Despite how physically tough they were, I wonder what it exactly was that got rid of... all of them?
I started wondering during this video:" why do vertebrates always have 4 or 0 limbs?" Like seriously, birds have 2 wings and 2 legs fish are limbles, mammals have 4 legs or 2 legs and 2 arms
@@bubblegerbil6828 i think it'l be more like tails in humans, theres technically still a part of the body you can associate with it, but it's not even directly visual
@@bubblegerbil6828 it might never happen. Whales have vestigial leg bones that just "float" not attached at the hip and without feet, but they are still there because no evolutionary factor specifically targeted it
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
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.
I feel it's just a misunderstanding by creationists, it's actually incredibly simple, requiring only two concepts: Offspring have mutations making them genetically different to both parents Only those fit to thrive in their environment will go on to reproduce and pass on their genes Iterate over billions of years in different and changing environments, and that's evolution
I honestly never questioned the possibility that there was a reason for this. Also aren't insects only so strong due to their size and the square cube law?
To busy using that for other things I guess, maybe life was to greedy being carbon based and all. (Idk I am no scientist, don't take what I say as anything more then wild conjuncture and yes I don't know if I am using that word right but I will use it anyway)
@bryan diaz varela That both does and doesn't make sense. After all, if we destroy the planet, we end up leading to our own demise. However, there are ways to counteract that. For example, reducing the amount of children we make would reduce that. I thing it really just is that we haven't gotten there yet, though I wouldn't be surprised if some creature gets this armor sometime in the future.
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 ;-)
Hi. I study Biologie in Germany and i wanted to say a few things. in the part where you discribed the evolution of protostomia and deuterostomia you had a few mistakes. Some were just not completly accurate pictures for the narration. For example you showed a nine-eye which is one of the earliest forms of fish (it isnˋt even folly classified as such because its so old) but is happend way later that what the narration says. Also what a person might think from seeing this video is that protostomia and deuterostomia are classified by the skelleton they have. it is true that you could say something like that and it would mostly be a way of classification. A problem with that are for example worms wich can be found on both branches wich have a hydro-skelleton or things like sqids witch have somewhat of a hard skelleton on the inside (evolutionary it came from the outside as well; their closest relatives are musscles and snails). Protostomia and deuterostomia are classified a bit different: before is a full human/ant we start from one cell which turns into a few cells which form a ball. this ball then dents somewhere. this dent then breaks through on the other side. we get a cell-donut. the hole of this donut becomes our digestive system. if the dent becomes the mouth we speek of protostomia (first mouth). if the break through becomes the mouth it is a deuterostomia (new mouth). otherwise i really love your vids
@@nateyenawine7856 i think it's unfair to think that. both make widely different content. one focuses on mainly biology and one focuses on _partly_ biology and everything else. on top of that, tierzoo is structured to be easier to digest for people who plays videogames, and this channel is structured to be easier to digest by the general public. i too think apples taste better than shoe polish, but both are good at their own thing.
Is a matter of size/weight. The same concept applies when building huge ships/buildings/aircraft). You need a geometrical increase in its structure volume (makes heavy and consumes more energy (less efficient))
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.

@@KlaustheViking bro if you genuinely think that isnt bad for him just because he uses the right technique youre dumb asf, the massive amount of strain he puts on his body isnt healthy, he knows that and takes that as a risk. strongmen lift for strength, not health.
@@Vexreal_ First off, I ain’t your bro. Secondly, weightlifters, strongmen, power lifters, and so on do mess their bodies up mostly because of using the wrong technique with lifting. The weight is only part of the equation, jackass.

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

I think its better this way, with our brains we can build suits/armor that imitate exoskeletons for multiple purposes. All we're really missing is hybridization with our bodies. To maximize on "hydraulic" performance for the suit. However. It is interesting that the opposite would be 100x harder to achieve, reinforcing bones or adding them into an existing exoskeleton would give little to no benefits.

I'd be curious To know why arthropods never developed larger brains like vertebrates did. Maybe a future show?
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.
They lived before dinosaurs and are still alive, maybe they will outlive us. Trading brains for survival.
In my opinion its the size issue again, for a bigger brain u need more space and to get that space without being called bighead u need to grow, but their breathing system is less efficient, so they dont grow to that sizes and so their brain also doesnt grow.

I would love to see what we would look like if by chance there was other alkaline earth metal rather than calcium.
Oh that's actually an incredible question I now need the answer to
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.
@@Quibblet JOIN THE GLORIOUS EVOLUTION
Actually, that can happen to you, if you ingest strontium(the element below calcium) your body will confuse it for calcium and use it to build the bones, tho it isn't healthy as it has different properties, and your body can't clear it out afterwards, and if it builds up, well you're kinda screwed
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. :-)

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

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
@@AngDavies the emus and kiwis have unused limbs, and i guess the salamander has floating bones like whales do
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.

Hi. I study Biologie in Germany and i wanted to say a few things.
in the part where you discribed the evolution of protostomia and deuterostomia you had a few mistakes. Some were just not completly accurate pictures for the narration. For example you showed a nine-eye which is one of the earliest forms of fish (it isnˋt even folly classified as such because its so old) but is happend way later that what the narration says. Also what a person might think from seeing this video is that protostomia and deuterostomia are classified by the skelleton they have. it is true that you could say something like that and it would mostly be a way of classification. A problem with that are for example worms wich can be found on both branches wich have a hydro-skelleton or things like sqids witch have somewhat of a hard skelleton on the inside (evolutionary it came from the outside as well; their closest relatives are musscles and snails).
Protostomia and deuterostomia are classified a bit different: before is a full human/ant we start from one cell which turns into a few cells which form a ball. this ball then dents somewhere. this dent then breaks through on the other side. we get a cell-donut. the hole of this donut becomes our digestive system. if the dent becomes the mouth we speek of protostomia (first mouth). if the break through becomes the mouth it is a deuterostomia (new mouth).

Is a matter of size/weight. The same concept applies when building huge ships/buildings/aircraft). You need a geometrical increase in its structure volume (makes heavy and consumes more energy (less efficient))
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.
