Technically dinosaurs never did stop evolving... many branches went extinct, however some branches remain to this day and are still under selective pressures.
We humans would not have evolved in the first place if most dinosaurs had not gone extinct. No one can know for certain what the present would look like if events in the past were different. But it is fun to speculate.
@@Samanosuke1138 thicker feathers provide better insulation, small size means less energy spent, a more omnivorous diet means broader selection of food. Evolution tends to be a give and take for the sake of survival, look at humans compared to the rest of the great apes: bigger brains but less muscular power. The strongest human alive could not go toe to toe with an average chimp or bonobo in a contest of strength, but we have the capacity to produce complex machines of death.
we are not top of food chain from the beginning. and even now. goto any forest and live without any tools, weapons. use only what body has. we wont survive long.
@@FATilleryIf hunter gatherer humans met dinosaurs somehow, we'd easily hunt them to extinction. The idea that we'd be hiding from a bunch of big scaly mammoths is ridiculous 😂 It's like saying cavemen were just "food" for bears and sabre tooth cats when it's the other way around...
@@SuperYoshikong 'If' is the key word. However, humanoid mammals did not exist when dinosaurs roamed the Earth. There were mammals in existence but they were just small animals who were, as I described, simply food for the larger reptilians (dinosaurs). Humanoid development did not occur until much later when dinosaurs had gone extinct.
@@SuperYoshikong IF hunter gatherers or humans managed to evolve. Thing is they never would have appeared. There is a reason dinosaurs dominated the earth for hundreds of millions of years despite mammals having existed during that time as well. The mammals simply could not compete and were forced to evolve into smaller forms more suited to survival against the superior predators. The only reason mammals ever took over the world is because the asteroid eliminated the competition for them
It's a strange title because they didn't stop evolving. Most of them are extinct, and the rest evolved into something else, like birds. A more accurate title would be "What if dinosaurs never went extinct?" Or "What of dinosaurs HAD stopped evolving"
If dinosaurs never went extinct then mammals would likely have never gotten the chance to evolve and thrive. I still love knowing what they could have evolved to look like though. I mean they only kept getting cooler every time period they dominated, so I always imagined they'd look absolutely incredible, maybe even nightmarish. Mammals and birds are pretty though so I can't complain too much about the poor dinos dying.
Considering the fact birds are dinosaurs, I reckon they would have been a real spectacle to look at. Can you imagine huge carnivores drenched in stunning, vibrant, colourful feathers . Using them to woo mates or warn off attackers. Prancing around and doing bird-like ritual dances when competing for mates and territory. They would have been utterly terrifying yet shrouded in otherworldly beauty. Can't even begin to imagine...
The TV show Star Trek Voyager offered one possible answer to this question in of its episodes. I think it was called "Distant Origin." In real life, though, one line of dinosaurs did keep evolving. Because of this, we have chickens, ostriches, sparrows, eagles, etc.
If dinosaurs never went extinct, our little mouse like ancestors would still be little and mouse like, so as to avoid predation. Mammals really only got larger because the pre-existing larger things that used to eat them, stopped existing.
That's not necessarily true. There were badger sized mammals that hunted small dinosaurs and raided nests to eat dinosaur babies. Just like there's Komodo dragons and alligators in modern era, mammals would have huge scary forms.
@@SuperYoshikong the peak that mammals could reach while dinosaurs existed was small badger sized things raiding unguarded nests and perhaps killing small hatchlings. The vast majority of mammals life was small mouse or rat like creatures. There is a reason mammals never caught up or got anywhere close to the top of the food chain while dinosaurs existed they were simply inferior.
This is a very interesting question. And many commenters are right....a branch of them (theropods) became birds. So birds are their modern descendants. Now, just for fun....a couple of decades ago, an episode of Star Trek: Voyager explored this question (episode title: Distant Origin). In those episodes it explored the possibility of what could have happened--and what they came up with was interesting: Some branches of dinosaurs had developed 21st-century style technology (so like rockets); and they built some "generation ships" to escape the asteroid apocalypse. Those that remained on Earth were mostly wiped-out, and any trace of advanced ancient dinosaur society and tech were completely erased. 65 million years later, the mostly human crew of the USS Voyager meet extremely advanced descendants of those dinosaurs that escaped (they assumed they were a new alien species). They were now bipedal and humanoid sized, and had very very advanced tech and gigantic starships. Took them sometime to realize those "aliens" came from Earth and were descended from dinosaurs. Excellent episode!
If they never stop evolving it's just like having standard animals. Like a Bronto or a Brac in a zoo instead of a Giraffe, a Microraptor for having a pet instead of a parrot, Compys instead of rats that infeat in farms and houses, we're having Blue instead of a lion in the safari. Still a normal day.
Trex tiny arms shows they're better of with more muscle around the neck and breast then heaving arms it's a trade of so they would likely evolve to not having them at all.
Okay, anyone who does not clearly and immediately acknowledge that birds are modern dinosaurs is lacking in credibility. And, to be clear, it's not that dinosaurs evolved into birds, but that birds are the kind of dinosaurs that survived to the modern day.
Birds. That’s what would happen if dinosaurs never stopped evolving, because it did. Some dinosaurs survived the great extinction event, and from that we have birds
you have the Voth, they were Hadrosaurs taken from earth many millions of years ago. they got very advanced in space technology. wouldnt be surprised if other dinos would get space travel
I mean, nothing ever stops evolving . . . their genetics either respond to stress and changes or they don't. That being said, if they were alive, and we were somehow able to evolve to what we are now in spite of them, I'd imagine they'd be getting smaller since the air is thinner. The large sauropods would either die off or their young wouldn't grow as big (so they'd shrink to maybe 2x the size of an elephant maybe). Raptors could either replace, or be joined with, dogs as our day to day companions. The smaller dinosaurs would probably be like land parrots (like the kokopo, kiwi, or their larger cousins the ostrich or cassowary).
They continued evolving by decreasing in size to adapt to a scarcer food source, increasing the feather coverage for better insulation, and developing beaks to be able to pick seeds and fruits from the ground and branches, although many of them remain carnivores.
Assuming that the asteroid never hit, humans would've never become what we are today. We'd still be little mammals, running for our lives. The dinosaurs would continue to evolve. To be honest though this dinosaur video is way better than all of Bright Side's dinosaur videos combined.
Type 1 Now we are talking. We can’t find out how long it would take us to reach that level because human development is kinda random. Maybe another cold war could make it a million times faster. Seriously. A scientist during the cold war, could go to the American government and say one word “Russia” and the government would reply with two words, “How much?” This was the era when we saw amazing development in an amazingly short period. The current American monopoly doesn’t make it seem important to the government to fund those scientists more. Ok, coming back to type one, when we become the planetary civilization. Now our main fuel source is NUCLEAR FUEL. But you would argue, isn’t that a thing today? Well, yes it is, but it is 1, dangerous to operate so not used in bulk, and 2, we use nuclear fission for our energy. The type one civilization will be based on nuclear fusion. Fusion releases a lot more energy and can be performed with simple elements like hydrogen, compared to fission, which needs rare metals like uranium or plutonium. We would have propulsor technology which would allow us to launch rockets into space without using that absurd amount of fuel, and make interplanetary travel easy. Type 2 Now we are a stellar civilization. The main source of our energy is nearby stars. We are now so developed that energy from nuclear fusion is not enough to fulfill our development needs. So, we take the next leap, Energy From Nearby Stars. No, I don’t mean we would plant solar panels in the oceans, we would plant them on the star…yup. Freeman Dyson, a theoretical physicist originated the concept of a Dyson sphere. We would build a system of rings around a nearby star and obtain all its energy, for our use. A very interesting event happened with a star names Tabby’s Star. Its intensity suddenly dropped by 22 percent! Scientists suspect the only way this is possible, as far we know is if someone built a Dyson sphere around it, someone who is already a type two civilization. Here is the quote from the wiki, Type 3 Introducing the Galactic Civilization, and the final level according to the original scale. Our energy source would still be Dyson’s sphere, however, this time we will build them all over the galaxy to fund our experiments. We would be able to access wormholes and zap through space. It is a theoretical object if you don’t know what that is. Imagine the universe as a piece of paper. You are on a point on a paper and want to go to some other point. Instead of traveling, you fold the paper in such a way that the point you are on and the point you want to go in touch with each other. Then you make a hole in your location and enter the place you want to go to. This is roughly how wormholes would function. A type 3 would not be able to build wormholes but can zap through preexisting ones. Type 4 Now we are a universal civilization. Our main energy source is supernovas! That is when a star explodes, releasing an absurd amount of energy. We would be traveling through multiple galaxies and extracting energy from supernovas. At this stage, humans would become immortal, like seriously! We would be able to upload our consciousness, the feeling of existing, along with our memory and experiences into a computer, and live in the metaverse or download that consciousness to another body, like the body of Ultron, and switch avatars and stuff. Being free from our biological bodies would open up new horizons for this civilization. We would also be capable of creating type 0 civilizations. They are kinda god-like, but not quite there yet. Type 5 Being a type 5, humans realize something amazing, they find that multiverses exist. This might sound like science fiction, but remember going to space was also fiction in the early 1900s, having self-driving cars was fiction in the late 1900s. So now we are MULTIVERAL CIVILIZATIONS. An unimaginable amount of energy would be required to go multiversal. A type 5 civilization will probably be looking for White Holes at a time. They are only theoretical but their existence can be proved using Einstein’s Field Equations. It has been estimated that a white hole can emit energy equivalent to 14 million times that of an average galaxy! Now humans might assume they are at the peak of civilization, but soon they will realize the greater truth. Type 6 We have always lived in a 3D world. Our brains are not capable of imagining things in the 4th dimension. But a type 6 can make their brains for their conscious selves. Their bodies are nothing but pure consciousness, and even going up by one dimension we would become a hundred times more efficient. Type 7 But now, humans think they have reached the peak of their civilization. There is no greater truth that they do not know. It is now time that Humans realize the existence of a type 7 civilization, the one we all worship, yes I am talking of the existence of Gods, the real type 7 beings…would be pretty cool right? Many scientists consider we would never really reach the status of a Type 7 civilization. A type7 can manipulate the laws of physics it can make matter from the vacuum, and generate a tremendous amount of energy with its Godly Power. That’s why type 7 has been rightfully called The Creator Civilization, which can build its universes, with any laws of physics, and play with the laws of physics and manipulate them the way it pleases. Millions of type 6 civilizations together cannot compare to the immense power of type 7. Feels sad no one will be able to develop to a type 7 or will we?
Dinosaurs were around for 200 million years. After the asteroid 66 million years ago, some still survived. If they hadn't managed to create technology or civilisation in that amount of time another 66 million years wouldn't make any difference. We wouldn't be here without the extinction event that took them out. You may as well ask the question about crocodiles and the crocodilia family. They were around before dinosaurs and still exist today. 250 million years. Things would have gone on just as they had for all that time.
I guess that they have shown are smaller things. Major impact - Mammals would not be dominant. Primates would not evolve so much. Humans wouldn't exist (Unless some other event would have done similar extinction of dinosaurs)
Hmm, I think if Dinosaurs continued to evolve, like without the meteor, they probably would have become smaller not bigger Remember, there was more oxygen back then, which is why Dinos got so big. As less and less oxygen was emitted, things got smaller I think that would be how it worked o3o
Actually no. There was more oxygen in the Cretaceous, not in the Jurassic and in the Triassic. Sometimes it was even lower than today. The massive size of the dinosaurs was due to their efficient respiratory system much more complex of humans, not to the oxygen.
@@DinoGoofHybridHero7531Yeah, the key to their size was mostly the fact they had attachment points along their spinal column to their lungs. Meant oxygen was almost instantly delivered to where it was required and at rapid speeds. This allowed them to grow very fast and also get very big. However, birds have these very same attachments sites, hence why many species of birds fully mature from hatchling in just a matter of weeks or months - very rapid growth by comparison to most other species. Yet, they decreased in size and instead used the gains from these lung attachment points to help them reach the skies. Many traits inherited from dinosaurs allowed birds to fly... So really, dinosaurs that were huge and/or four-legged and not very bird-like would have most likely stayed big or perhaps gotten even bigger. While the smaller dinosaurs would most likely have joined the birds we have today.
@DinoGoofHybridHero7531 No problem at all :) I'd give you direct links to sources but my comments have been getting removed... Maybe search "Vertebral morphometrics and lung structure in non-avian dinosaurs" in Google if you fancy a much more in-depth read. I did an entire unit on dinosaurs when I studied evolution at uni, my assessment / essay was on this exact topic :)
Yeah, I think we would have come up with modern weapons more early and advanced. Home sapiens are one of the most adaptive species that not only survive to be the fittest but also make sure the environment is comfortable for growth. So yeah, nothing would have stopped us from being the most dominant species in the world as like now.
Right away this is all in correct as they would of needed to evolve to be better suited to modern day oxygen levels and so on, so most things on this list die from staying large.
The movie is called "65" As in like 65 million years ago. :) I personally didn't like it but it had it's moments. More of a issue with a dumb kid ruining the movie for me. Lol
@@PestilentAllosaurus Thank you, kind stranger! And I looked into it. They… killed it with steam. Not gonna lie, I’m really bummed out about that. REALLY cool design… but I’m pretty sure this exact shot is the only good one in the whole movie.
They would have had to adapt to the numerous ice ages, which occurred several times over the past few million years or so. We're coming out of the most recent ice age, currently.
If dinosaurs survived the flood, including brachiosaurus, their would be no tall buildings or cities, because brachiosaurus is that gigantic. The T rex would eat up humans and flying dinos will Rome the skies. I'll see about it
Crocodiles and sharks are much older. Did they become intelligent? Did cockroaches become intelligent? The largest animal of all time roams earth at this moment which is Blue Whale.
But... Dinosaurs never stopped evolving. Today many of their species are still alive. Birds are all belonging to the group of theropods. That originated from dinosaurs. Birds ARE dinosaurs.
I don’t understand how dinosaurs were wiped out from a meteor yet, millions of other life forms survived. Like millions. People existed with dinosaurs. Why were they not extinct as well?
•The asteroid did affect millions of other species - over 75% of all species went extinct at the same time that the non-avian dinosaurs went extinct. The asteroid affected the non-avian dinosaurs so badly because, due to the lack of food after dust blocked out all of the sunlight, any land tetrapod that weighed more than 25kg went extinct (with a few exceptions, such as crocodilians which could hibernate). •People didn't live at the same time as the non-avian dinosaurs. The first upright apes lived 7 million years ago, the first species from the Homo genus lived about 2.5 million years ago, and Homo sapiens itself only evolved about 300,000 years ago. Primates hadn't even evolved yet when the K-Pg extinction event happened 66 million years ago.
All of this is assuming that dinosaurs wouldn't have evolved dramatically from a mental standpoint. They'd possibly be millions of years ahead of where we are at now.
well technically dinosaurs would not have kept getting bigger if anything would have evolved to be smaller with lower oxygen levels in the air compared to what there was then studies say that nothing would have evolved to be that big today they would have only shrank in size
maybe some dinosaurs which are strongly related to veliciraptor would evolve to (mostly) flying reptiles. lets call them birds. if these birds would exist nothing would change, because the actually exist
I disagree that any of them would have gotten larger over time. Back then the oxygen content in our atmosphere was much larger than it is today. Which allowed for larger animals to exist. Today, if you resurrected a Titanosaur it would probably slowly suffocate.
I'm confused. Dinosaurs already evolved into birds. It can also be argued birds also have distinct evolutionary advantages over us. They are way more diverse and as a result adaptable to change. Some are know to be quite intelligent, capable of using tools and communicating. Some of our local birds now follow delivery trucks and steal parcels and groceries. They are very food adaptable and require less resources than us. There's a good chance dinosaurs may still inherit this planet as birds.
@@vedantnikhar8247 my friend says crocodile is the nearest family to Dinosaurs and when i'm seeing Dinosaurs like Spinosaur and crocodile I agree how she feels and you said chicken, yes chicken is the nearest family of T-Rex. 🦕🦖🐊🐔
@@vedantnikhar8247 That kind of predator/prey relationship is why birds get the benefit of a speedy evolution. with crocodiles being stagnant and having a reducing suitable habitat.
The dinosaurs that weren't killed off by the asteroid evolved into birds. This is basically asking what if there was no asteroid. When the asteroid hit, it pretty much took out all non-avian dinosaurs. Dinos that lived near rivers/streams (such as the crocodile ancestors) survived as well, as their food source was mainly aquatic life. So basically, the birds we see today are decedents of dinosaurs that were ALREADY flying by the time the asteroid hit. This video is asking the question of how the large, purely carnivorous/herbivorous dinosaurs that were wiped out would evolve.
@gracewang1805 Because the extinction of the dinosaurs allowed mammals to step up and take their place. If 99% of dinosaurs survived, mammals would have just continued to be small scatty rodents etc. which primarily served as food for the dinosaurs. Those mammals would therefore never have evolved to become us or even anything remotely close to us. It's actually more likely that one of the more intelligent species of dinosaurs would have assumed the role of the most socially and psychologically advanced beings on the planet.
@@kingdon7795 Please see my comment above. I really don't think humans would have had a chance of becoming as we are today. Mammals would have remained small to avoid being eaten as much as possible.
It’s a clip from a movie called 65 with Adam driver as the main cast and they were leaving the “earth” just before the asteroid hit earth and wiped out the dinosaurs
@@nevergiveup5939We live and die so that others can live and die after us. Continue to pass on our genes and allow evolution to carry on. That's the whole purpose of life and death. It's a cycle.
Yeah, but that was only one (relatively) small family of dinosaurs. There were hundreds (more likely thousands) of non-avian species that went extinct.
Dinosours would have enough time to evolve into some intellegent humanoids. Sory Reptiloids ! Just think about how long it has taken for mammals to evolve to humans. The dinosaurs would have the same time and even an advantage from the start.
Even a single Velociraptor would be a deadly threat to any human that is not prepared to fight them. It's bigger than the usual dog, at least as intelligent, has not only sharp teeth, but also its large sickle claw that would slice your belly up to spill your organs in a heartbeat. It would eat your organs first, while you were still alive. MUCH more than a "vicious turkey". And yes, they were pack hunters.
@@electricdawn2258 too much Jurassic Park. Any animal the size of a small dog would have a hard time spilling a human's guts "in a heartbeat". Not saying they're not dangerous, but that's a little overblown. There are bigger raptors though.
@@RenzorTheRed Totally not Jurassic Park. They are LARGER than the average dog. I know that our dog Reilly would be able to kill me, if I'm not prepared for her, and she's a 20kg (about 45lb) Malinois/Podenco mix. She stands as tall as my knees. Which is less than a regular Velociraptor's height. I might be able to survive her, but then I'm 200lb+, 6.3ft. My wife, at 50kg (110lb) and standing 1.63m tall would stand NO chance against her. And our dog's strong as well. My wife can almost not stop her when she wants to go somewhere we don't want to. You keep forgetting that our best weapon is our intelligence. We're not very capable bareknuckle fighters, unless we trained for it. But if you're alone, not prepared, you stand zero chance of surviving an attack of a pack of predators. Whether that be wolves or velociraptors. In fact, I think, if somehow velociraptor had survived and had filled the niche of the wolf, they would probably be our best friends today, instead of dogs. 😉
@@RenzorTheRed fyi a ROOSTER can kill you because they have spurs Velociraptors have claws specifically designed to kill A velociraptor can absolutely kill a person, death by bleeding out.
65 million years ago, our ancestor was persecutus, the famous ½ lb shrew-like creature. Without the end of the reptile overlords, there likely never would have been the great apes; let alone "intelligent" ones. Pterosaurs aren't dinosaurs.
@@marks.9448 That was the notion 50 years ago, yes. But nowadays, and for the last 30+ years, and across all of paleontology, birds are viewed as the descendants of dinosaurs while crocodiles and lizards in general were a pre-Mesozoic offshoot from the evolutionary line well before dinosaurs ever came along.
@@iamfritz both crocodillians and dinosaurs (including birds) are the only 2 living lines of Archosauriformes. --> if birds arent reptiles than none of their ancestor was a reptile --> their last common ancestor with crocodillians wasnt a reptile --> crocodillians wouldnt be reptiles. --> Archelosauria wouldnt be reptiles --> turtles (and relatives of turtles like plesiosaurus) wouldnt be reptiles --> only Lepidosauromorpha (including snakes, lizards, and Tuatara (+ extinct species) would be the only real reptiles and all ancestors of them wouldnt be reptiles.
The species that survived the meteor strike DIDN'T stop evolving. Theropods are *still among us.* We just don't call them *dinosaurs.* A famous English playwright once wrote in one of his plays, "What's in a name?"
@@benjaminbryantjr4262 Sure, but no animals remotely as huge as the biggest carnivorous dinosaurs. Mammuts, yes, but they were herbivorous. Unlike many dinosaurs.
@@benjaminbryantjr4262Look up the straight-tusked elephant.
