Could A Mammal As BIG As King Kong Ever Exist? DEBUNKED 

Once huminoids developed the spear, being a large mammal became a disadvantage.

scientifically accurate Kong looks like a giant ground sloth

Plot twist: Kong is just the size of a gorillla or a gigantopithicus. However, the human's shown in king kong are tiny, the size of a real-world monkeys. Kong isn' that giant, but the humans shown are that small.

Now we need vids on scientifically correct godzilla, giants, merfolk, undead like zombies and vamps, and dragons!

So its prooven, that there has to be life on Mars, because Kong exists. Very nice

Thank you for telling me that a giant 335 feet tall gorilla that fights radioactive giant lizard scientifically could not exist

I love the scientifically accurate Kong 😆

"All large herbivores have small heads." Really? Name one. All of the large herbivores i can think of have enormous heads. Elephants, rhinos, hippos, moose, horses, elk, bison, buffalo, etc.. all of them have heads relatively large for their body size.

Giraffatitan isn't a titanosaur, it's a sauropod from the Jurassic period and is more closely related to brachiosaurus than the titanosaurs from the Cretaceous period.

If scientists really are intent on trying to bring back extinct animals, then the woolly mammoth(or any ice age fauna) would be the ideal candidates for de-extinction as they only went extinct around 4000ya and if you released them in areas such as Siberia or Greenland where the conditions are similar to when they lived, I'm sure they'd thrive. Also on the whole dinosaur cloning thing, DNA has a half life of a few hundred years, so even in perfect conditions all traces of DNA would be lost after a few million years

8:55 The only problem with the hypothesis about the heat is that the. cells would have adapted and produced less heat. Mammal cells produce the heat they do because it's advantageous for moving around or whatever. But if size had been a better advantage thEn the cells would have adapted to produce less heat like like reptiles.

You left out power (in watts or horsepower) or energy (in joules). In movies, they show creatures that are 10 times taller than normal, moving ten times faster. They do that because showing a huge creature moving its fist at 1 meter per second looks very slow. So they make it move its fists and legs at 10 m/s . That means that is moving a fist that is a thousand times heavier (10x10x10) ten times faster. At 1/2mv^2 (m is mass and v is velocity), the kinetic energy would be 100,000 times more for that creature that is, "only" ten times taller. In those movies like Pacific Rim, Transformers, Kong v. Godzilla, etc. every step would be the equivalent of nuclear bombs and just having them move around would be devastating.

I really have to disagree with Mark Witton's reconstruction of King Kong as it seems to be reconstructed purely around size alone instead of taking ape evolution and adaptation into account. This is mainly because there was a selective advantage for apes to not only climb but to swing around into the trees for navigation but to also grasp food with their hands so they can eat it. Even when giant apes like Orangutans, Gorillas and Gigantopithecus evolved to be quadrupedal, they retained this feature as it helped them to not only battle one another or to defend themselves from predators but to reach for food especially when they had to climb high into the trees. But since a hypothetical Kong would be too big and heavy to climb trees, he would solely use his arms to reach for food high into the trees along with using them and his body weight to break them down if he can't reach it. This is different from animals like a Paraceratherium which not only evolved from a running ancestor but also there was a selective advantage for it to evolve a long neck when it evolved gigantic body sizes. . Since you brought in different incarnations including the Monsterverse Kong, I am going to go into two scenarios where one remains as a bipedal ape and the other evolved to be a quadrupedal ape. If the former happened, well I am going to let Tiina Aumala's (aka Osmatar's) reconstruction of Kong titled the King Ape to speak for itself (which you can freely search up for yourself.) If the latter happened, his body plan would more likely resemble that of giant ground sloths as especially Eremotherium as they basically would have a very similar lifestyle to apes minus the tree climbing due to their size. Coincidentally, the biggest Eremotherium would be bigger than the original Skull Island Kong who was 5.8 meters/18 feet tall. . That is basically what I think and you can feel free to disagree if you think my reasons aren't sound enough. Besides, good job on making this video.

Heres the thing, sometimes in the older movies, King Kong was only like 15-20 feet, so there very well could have been, and probably has been a technically "king Kong" species before on earth

Gigantopethiticus: Am i a joke to you?

Very informative! I never thought of how avians and mammals are different in their number of offspring, with mammals being affected by size scaling.

i wonder how big creatures could get if their bones were of some other material, like if somehow they were a titanium alloy or some sort of carbon structure. along with having more efficient muscles of course

I have a slight problem with the current weight estimates of Gigan Blackii. At 16:30 his weight is dramatically too low for an organism of that size. Consider the fact that adult male Gorillas can reach weights of about 400 to 500 lbs at around 5 feet tall. Now that puts them at 5 feet shorter but only 150 lbs lighter than Gigan Blackii. Following the square cube law that weight estimate feels really really off. Other than that good presentation. 🙂

The big sauropods were already slow and built for energy efficiency Can't imagine a mammel that size zumping around lol

@2:22 unless the gravitational constant itself has changed (which we have no evidence for) I would like to see a movie where they gave an explanation for Kong's giant size that, at the very least, couldn't be disproved. You might need new physics and/or exotic matter though.

Now create politically correct king kong

Is there a theoretical limit to how heavy a land animal could be? If we've already discovered dinosaurs that could have been 100 + tons, is it possible that we will discover dinos of say 150 tons or 200 tons, or have we pretty much found the biggest land animals that could have existed?

"• dwayne johnson." 😂

Just so you know african elephants can get to 4m tall and weight over 10 tonnes. That's taller and heavier than any T rex found

0:58 short neck giraffe isn't real, it can't hurt you Short neck giraffe:

"Hm, what was i watching this video for?" 11:07 "Ah yes, kong"

I saw video years ago about this topic and it mentioned about the heart, size and power to pump the blood, which is quite impossible. I wonder why it wasn't mentioned here 😊

Correction: Hollow bones as found in dinosaurs and birds are NOT lighter than the bones of other animals. In fact, the skeleton of a mouse sized bird is heavier than the skeleton of a mouse. While the bones are hollow and have air pockets, the actual bone material is more dense, so the bone isn't any lighter.

0:15 Love the Dota 2 Ursa ultimate sound effect here.

Kong was originally made to be 15' tall and there is a line where Denham sees Kong next to a stone pillar which he later measures to get a height estimate. However, in the original King Kong movie, they kept making him larger and larger with each scene until he was closer to 30' tall when killed. Movies follow the Law of Increasing Evil where The Hero can fight someone his size but the next movie, the producer says, "Let's make the bad guy bigger to get more crowds in." And so the bad-guy/monster gets larger and larger because the audience gets bored with the monster always being the same size.

I had been thinking of this same concept for a video, I even had a half finished script and 3d models for my speculative real world King Kong. most of my info is identical to what's in this video as well (specifically regarding the limiters for size, and info on the extinct giant mammals). I still might make the video, but I would have to focus more on the speculative Kong's biology and behavior to not be a worse version of this Excellent video 👍

Dog I've been promised a mammoth for like 20 years now.

It's worth noting, your statement that the oxygen in the atmosphere may have been as high as 35% 300mya is also 100m years before the dinosaurs.

Whats the name of the program that you use for the animations?

I've got an idea for a video, how do I contact you?

Gravity from back then did not exists cause Isaac newton didn’t discover it yet

What's your favourite Kong from which movie??

One of the questions I have about Kong (or other monsters) is whether or not the buildings they climb or jump onto could actually hold their weight! I'm sure that if Kong tried to climb the Empire State Building, it would collapse before he got more than a few stories up!

King Homer LMAO 😆

I think the main issue with all the theories put out of animals experiencing extreme gigantism is that they would have conventional bones and muscles. When in reality if an animal were to reach a size if a multi-story building, it's structure would be made of a material that is reinforced enough to support it's size

Alright we got a scientifically accurate Kong, where’s Godzilla? I wanna see how realistic a giant fire breathing semi aquatic lizard is- XD

I forgot this was a video about king kong lol 😂😂😂

I wouldn't exactly call myself a writer, but i do create lots of characters and worlds. To introduce monsters, dragons or any creature of enormous size, i always do it alongside some type of natural adaptation that enables gravity manipulation at an unconscious level.

Do you have a video about scientifically accurate titan and or giants?

I am glad we added the competition portion to the giraffe segment. We don’t want people getting the wrong idea about giraffe necks. 😆

7:55 *cries in paleoloxodon* Ah im stupid

Great video, as always. Thank you.

Asked and answered, the director of Kong: Skull Island has already stated that his Kong is not a giant gorilla it's a monster that just happens to look like a gorilla. So there's that.

12:18 it kinda does occur actually. There is a mutation called gigantism, which has the name suggests results in people growing very tall. This mutation does put strain on the skeletal system (as well as a circulatory system). In nature, such issues would greatly reduce one’s chances of survival

Awesome video but did you just say giraffatitan was a titanosaurus? I think it was more akin to a brachiosaurus...

King Kong:🔥🔥 Scientifically accurate kong:😹😹

The surface area to volume ratio (square-cube ratio) problem is true, but why didn’t it apply to large theropods? We know for a fact that small theropods are endothermic. Tyrannosaurs should have also overheated.

The silly way he says is words is so fun

Kong's body is probably comprised of magical unobtainium so that he can withstand these forces

A gigantopithicus would've been insane to see in real life

I always find it amusing when science lovers try to postulate ancient prehistory theories as though it’s all easily accessible knowledge while simultaneously having to caveat everything with the disclaimer that we don’t actually know for sure. It’s like “look at all these cool and interesting ideas we have about the time before man that are technically purely hypothetical.” I’m sure it’s the same mentality some people have with deep ocean sea creature theories and whatnot.

Now i don't say there's a way for evolution to go there but i like to imagine a gigantic animal with a hollow structure. Legs like the eifel tower, sorta. Horrific and weird.

16:25 thats still massive and im willing to bet there were specimens that were much bigger

I thought the biggest known Mammal was an Elephant that got to the size of a quite respectably large Sauropod (I don't remember which), just minus the neck adding a lot to the height

You ignore atmospheric pressure. While it has been difficult to find concrete evidence we expect the atmosphere to have been 2 to 3 times as dense meaning 20% back then would be as much as 60% oxygen today.

I forgot that this vid was about king kong mid way😂

*"Reality is often disappointing."* - Disney Marvel Thanos

interesting topic!

Well... you don't always need natural selection in favor. In theory you just need to not have it favor smaller stature and they could randomly grow bigger, though that could give huge variance inside of a species or mate selection could do it.

If we’re talking about the more iconic King Kong that everyone pictures fighting air planes on top of Empire State, Maybe. But Kong from the MonsterVerse, Not a fucking chance.

Thing is gorillas are already really robustly built so I'm not sure square cube law is much of an issue for them.

However, the wooly mammoth was not more of a giant than its contemporary relatives, the Asian elephant and the somewhat larger African bush elephant.

No. Mammalian limit is covered by Paraceratherium, "Mammut" borsoni and Palaeoloxodon namadicus. A mammal with roughly human dimensions like Kong has an even lower upper growth limit. Probably 5 metes tall would be the absolute limit for a mammal with an apish form (Gigantopethicus was nearly 4 meters tall).

Kong, in the new canon, comes from a pseudo parallel realm, along with the other titans. Hence their size and ability. Cause its a movie.

I recently heard that dinosaurs were all aquatic and had to be to support their weight .

Kingkong grabbed Jynx from pokemon

Man, this channel is unreasonably underrated 😢. You guy's production is top tier 💯

I think we may be surprised if we were to see the animals of other planets. Which information would change our perspective.

I was waiting to see where the Abominable Snowman from Rudolph fit in 😢

Hmm. Co2 levels look pretty low at the moment on that graph. Interesting...

very intresting to see thath kong would have looked much more like paraceratherium then a ape

How many eggs does an ostrich lay? How many eggs do large eagles and condors lay? It seems they lay a comparatively small amount

Another day, another amazing video ! 🎉😊

I believe Giraffatitan was not a Titanosaur, but a Brachiosaurid, while the tallest Titanosaur was Sauroposeidon, with highest estimates up to 18 meters. I learned this because I actually did a video on the similar topic several weeks ago, tho not so well-illustrated 😅 in case you are interested: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-baZ1bmL-0WA.html All in all, your channel is amazing and was a huge inspiration for me to start doing my own 😀

So sick of people calling it a nuclear winter when it's a volcanic winter when it's the result of a volcano (or volcanoes). Volcanoes don't spew nuclear radiation.

The size scaling of Kong is fucking everywhere

I believe they got so big because of breeding selection and Nourishment. Not only fauna when extinct, flora too. What if they are super nutritious group of flora that went extinct because of the fauna and they evolved to be less nutritious to avoid being overconsumed

In the antient Hindu temples it talks about a prehistoric animal(yali) wich lived among humans who could catch and throw elephants by its trunk . It had a lion mane and a elephant body . So why not ?

You guys said that if it started to grow really big it's head would start to get smaller so maybe we're underestimating the size of the extinct orangutan??

Can biggest human defeat smallest gorilla?

10 ft tall and 660 lbs. would be quite thin - proportionally the same as 5'10 and 130 lbs. or 6'10 and 194. 10 ft tall and 440 lbs. would be ridiculously thin for something resembling a gorilla. The picture they show for Gigantopithecus - chunky with no neck - looks like it would weigh more like 1500 lbs. if it was 10 feet tall.

How small could humans get while still functioning properly? I'm not talking about people born short but if we were to see mankind shrink down in size how far could we go before encountering problems with our body layout?

1 thing everyone don't understand is dinosaurs lived for hundreds of years not a hundred takes a long time to grow that big

It’s virtually impossible to find a fossil of ANY KIND that represents the largest example of that animal.

The air sacks in the necks is a recent theory.

Just think about the tallest people in the world. Many need canes or braces to walk and in the NBA drafting people 7’3”+ always causes concern about injuries because people simply aren’t meant to be that big.

Sauropod-like Humanoid Kong 15:12

i dont think the fact that co2 means plants grow is still legal in neusprech.

What we definitely assume as a long time , is not that long on a cosmic scale.

Title: could a mammal as big as king kong ever exist Paraceratherium: yes For people who don’t know: in comparison with the King Kong from Marian C cooper (the original King Kong): this Kong is up to 24ft tall while the paraceratherium is up to 24 - 26ft tall. Even in weight the para outclass him. having 15 - 20 metric tons weight compared to King Kong 1933 who have a weight of 4.5 metric tons So in conclusion: yes there is mammals that can be as big as King Kong, EVEN MORE THAN YOU THINK (because size is measured on mass)

This is assuming that Kong is just a normal ape that has been upscaled, and not an otherworldly giant mutant freak of nature that is not confined to the physiological constraints you have described. They are TITANS, and like Godzilla, they don't follow the rules of what we think is and isn't possible.

We as mammals still pay for specializing in doing tiny stuff during messozoic. None the less the biggest animal (that we know of) is a mammal and lives today.

I would imagine that a Kong size mammal would have a Dimond/ Graphene type structure which is at lest 70x to 80x stronger then normal bone , how much bigger that would make a Gorilla type cryptid I couldn’t say .

Ok no kong... but what about mighty joe young?

From the thumbnail i thought he was supposed to be completely hairless lol
