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

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

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.

scientifically accurate Kong looks like a giant ground sloth

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

I love the scientifically accurate Kong 😆

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.

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.

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

"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.

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

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.

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.

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.

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

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?

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

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

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

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. 🙂

@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.

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?

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

"• dwayne johnson." 😂

Great video, as always. Thank you.

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.

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 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.

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.

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!

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

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

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

I would definitely look into giraffe evolution as it's really more apparent that giraffe necks may have grown mostly for mating competition rather than food competition. They typically eat shrubs and bushes low to the ground.

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

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

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.

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

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.

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

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

King Homer LMAO 😆

interesting topic!

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

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

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

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.

If anything, the colder the environment, the larger creatures get and the longer they live

The size scaling of Kong is fucking everywhere

7:55 *cries in paleoloxodon* Ah im stupid

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

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.

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 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 👍

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

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...

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.

Another day, another amazing video ! 🎉😊

Sauropod-like Humanoid Kong 15:12

Square-Cube Law, the enemy of all kaiju.

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

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

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.

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

Kingkong grabbed Jynx from pokemon

We need to rename mars to skull island NOW!!!!

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

great content.

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??

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.

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

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.

That's true but Kong is a Kaiju not a Gorilla but your still correct 😊

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

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.

A primate as big as king kong could exist on water. It could be a species that only recently moved to water, so it didnt lose its primate traits yet. If blue whale exists , a king kong like ape could exist on water. Just imagine a primate that evolved to walk on the floor of a lake. It had to be a really big lake, however , it was stated that kong was the last one of his specie, this specie wouldnt last long and would have very few individuals to begin with.

No.... There was definitely less gravity 65+ million years ago...I was there... And I was like, 19 and 3 quarters feet tall, rode a dinosaur, and painted landscapes in my free time...

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

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

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).

Can mammals get gigantic? Well, the biggest animal ever confirmed is a mammal and so is at least one that is speculated to have been bigger.

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

The sad thing is the movie industry instead of becoming more realistic over time, constantly makes more and more exaggeration. What do they want? Why do they think they need such exaggerations (instead of better and newer stories), to keep themselves relevant to the public interest?

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

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)

biblically accurate kong

What's your favourite Kong from which movie??

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

The reality is completely different from Hollywood movies.

Kong during 2024 is actually 337 feet

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.

I really liked your take on gigantism. But real question is that why mammals are not as large as dinosaur. If we have proof that some dinosaurs gave birth to live babies. Coz giving birth to multiple eggs at a time is more affordable than live baby. So large dinosaurs can exist but not mammals esp on land.

Paraceratherium is an extinct genus of hornless rhinocerotoids belonging to the family Paraceratheriidae. It is one of the largest terrestrial mammals that has ever existed The shoulder height was about 4.8 metres (15.7 feet), and the length about 7.4 metres (24.3 feet). Its weight is estimated to have been about 15 to 20 tonnes (33,000 to 44,000 lb). en.m.wikipedia.org/wiki/Paraceratherium

Scientifically accurate reaper leviathan when

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

kong is a fictional animal, and the sizes of it's species vary from one film version to another. famously, for the 1933 original, willis o'brien gave the figures of 30 meters tall on the island and a larger number in new york, since the sky scrapers were bigger. much of the science given here was probably known even then, and the remains of gigantopithecus were discovered a year earlier, but a single gigantopithecus-sized ape wouldn't be a math for the dinosaurs on skull island, unless there were groups of such apes who hunted in packs. that would have been impossible to achieve with the technology of the day, as advanced as it was. it would have certainly made for a very interesting plot, even if it was eventually focused on a single ape. anyhow, without an official estimate of kong's size one guess is as good as another,
