What If Dinosaurs Never Stopped Evolving?

Sixty-five million years ago, dinosaurs ruled the Earth. They dominated each time period they were in, becoming the kings of the animal kingdom. Then suddenly, that all changed. An asteroid came for Earth and wiped all the dinosaurs out, causing them to go extinct. But what if things were different? Time to turn back the clocks over 65 million years to see just what course evolution would have taken if dinosaurs still roamed Earth.

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.

[@McNasty43]

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.

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!

[@KAZVorpal]

Velociraptors (dromaeosaurs) DID evolve to have wings. Microraptor is an example of a dromaeosaur that had complete wings and probably could not just glide, but engage in powered flight.

[@YoungAndFacetious]

The question this video is asking "what if the asteroid that killed 75% of dinosaurs never happened? What would evolution look like for these larger creatures that did not survive?". The extinction of these dinosaurs led primarily for the ability for mammalian life to prosper, there were already mammals on the plant during the late cretaceous period. Many of these smaller mammals survived, then thrived. The asteroid was the 5th extinction event to happen on earth. Without this event, life for a long time would of continued unchanged significantly for many years, but that wouldn't of stopped the events that followed from happening. As the atmosphere alone started to cool, the cold blooded dinosaurs would need to migrate or adapt to regulate their temperatures. Avian's would still hold the advantage for their ability to migrate quickly in rapidly changing environments, with flexible diets. Carnivorous dinosaurs would likely get smaller, as the plant life got smaller/seasonal causing herbivores to get smaller and decrease in population. By the time the time the ice age came around (of which early humans existed) the mammal population would of likely grown exponentially due to the dinosaurs inability to withstand the drastic changings or they would have adapted with features/behaviors to help them withstand the fluctuation. Such as smaller stature, thick coats/pelts, dense fat reserves, burrowing, or the ability to put themselves in a state of brumation for periods of time such as crocodiles do today. That's not including the rising and falling of water levels or the vast shift within out tectonic plates that eventually gave us the land masses we have today. Humans have adapted alongside apex predators since their evolution, within this we have found ways to utilize the life around us. We ride elephants, train hawks, domesticate numerous prey animals, and influenced the evolution of our own personal companions out of an apex predator. We will never know outside of speculation, but its not outside the possibility that humans could of farmed the descendants of brontosaurus, herding from the backs of a watered down symbiotically tamed version of a raptor species.

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).

It would be cool to see dinosaurs for real but at the same time it would be scary if they chased you

[@octavio.santos]

Well, we'd have one of Chrono Trigger's endings coming true.

What if billions years from now another species will make a video like this saying "What if human never die"

[@arthurfrost9004]

We could've had Lizardmen, Beastmen and all them stuff if 75% life didn't get wiped

[@fullrank6408]

what if aliens where once dinosaurs who evolved into extra terrestrial beings

[@borthwey]

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.

Any idea where the monster at 3:40 is from? Might want to watch it, cause dang does it look cool from that angle!

[@PestilentAllosaurus]

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

[@rjmdraco2592]

@@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.

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.

[@user-kq8cg1xg2k]

What would we live in with the threat of a clumsy brontosaurus stomping around?

[@markfrank5937]

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.

[@GiQQ]

How do we know some dinosaurs were intelligent?

[@fabriziobiancucci7702]

We can look the traces of their brain in the skull and make assumption. It's impossible to correctly estimate their IQ, but we can come very close

[@karlwitkowski4820]

What is far more important than an asteroid blast itself impacting the earth to eliminate dinosaurs. It is how an asteroid impact can over time affect the earth's atmosphere and air composition which results in overall larger or smaller creatures. Higher oxygen (prior to impact) bigger animals, Lower oxygen after combustion(post impact) smaller animals. Even though we today vastly believe the asteroid caused most of it instantly, I mean yes in the end many lives, but the idea I'm offering to come across is that the impact changed the atmosphere, even if significant amount of life was instantly impacted, the more significant change was the result on creatures due to the change in the atmosphere, which likely took decades if not centuries.

[@Adionte]

Humans, we fear nothing we would be making pets of these Dinosaurs. We always find a way to calm you down.

[@etiennereijnders8848]

I think you missed a point, dinosaurs would have become as smart or smarter than humans now, and build their own civilisation. Do a show on how that civilisation would look and function

[@tomlyle4991]

The levels of oxygen was much higher 66+ years ago. That’s why they were able to be so large. If they were alive today, they’d be much, much smaller.

[@dixonfish2159]

It be national snack day. Poor sent out for feeding time

[@SuperYoshikong]

If 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 😂

[@davejohn2335]

Saw the thumbnail and I thought they were going to evolve with our help of robotic parts

What if we live in a universe with different laws of physics?

Silurians according to Doctor Who

05:20 f The pterosaurs were archosaurs but not dinosaurs. Pterodactyls were a subgroup of them, and they weren't large. The Azdarchids were large.
