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

[@sirwabaloo7930]

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

[@jaschabull2365]

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.

[@laughingmonkey5522]

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.

[@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.

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.

[@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.

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

I'd be curious To know why arthropods never developed larger brains like vertebrates did. Maybe a future show?

[@katastrofygames]

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.

[@HIKOL_Nightcore]

They lived before dinosaurs and are still alive, maybe they will outlive us. Trading brains for survival.

[@timk8869]

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.

[@jarvis5552]

Oh that's actually an incredible question I now need the answer to

[@Quibblet]

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.

[@LecherousLizard]

@@Quibblet JOIN THE GLORIOUS EVOLUTION

[@wisemysticaltree2866]

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

[@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. :-)
