Bird Evolution: The Mystery of Feathered Dinosaurs | SLICE SCIENCE | FULL DOCUMENTARY

- How did birds evolve? How did feathers and flight appear? After a century of silence, these questions were raised again at the beginning of the 21st century when numerous species of beautifully preserved feathered dinosaur fossils were discovered in Liaoning, China.
By mixing images of fossils at the dig sites, ultra-realistic computer graphic reconstructions and interviews with paleontologists, The Mystery of the Feathered Dragons offers the viewer the opportunity to plunge into a modern scientific adventure. During this paleontological investigation, each new fossil helps to complete the puzzle of the transition from dinosaurs to birds and raises fresh questions. How did flight evolve in dinosaurs? Did they run along the ground to take off? Or did they glide from trees to land on their prey? Numerous parallel debates raged in the paleontological community until the discovery of Anchiornis huxleyi in 2009 - the missing link between dinosaurs and birds. More recently, in 2014, a completely new herbivorous dinosaur was dug up in Siberia showing that the presence of feathers went even further back in the dinosaur family tree. In fact, it’s possible that dinosaurs were feathered from the start of their appearance on Earth!

Cassowary is def a dinosaur
If you consider the bite force of a macaw or a cockatoo, you can begin to imagine what a Dino could do.. either one of those birds can LITERALLY bite your finger through bone.. now imagine a gigantic, angry(or rather hungry) cockatoo staring you down.. I don't doubt for a minute that dinosaurs are equally as smart as modern birds.. imagine that little Bacon Pancake bird.. now imagine it's 12 ft tall and carnivorous with 4 inch teeth.. I guess you could be thankful that your death would be quick although I think they may just bite you once and swallow you whole, play the possibility of being conscious for some phase of being eaten alive is horrifying
The animation and narration is excellent as well as the information.
Thank you very much !
@@SLICE_Science I agree! I really enjoyed this, and look forward to more. Subscribed!
But the background music is way too loud.
Just study a chicken. The rooster specifically. It's very easy to visualize a small raptor standing before you. If a rooster was as large as one of the medium sized carnivorous dinosaurs, there would be no doubt it descended from dinosaurs. In fact, roosters represent really ferocious raptors. They attack with their claws forward then, their beak goes in for the kill. Roosters can be exceptionally viscious & relentless. They can inflict serious injuries very quickly. Just imagine if they had teeth instead of a beak & a large sickle claw on each 3 toed foot, along with a long tail. Chickens are omnivorous & exactly like truly terrifying little pack hunting raptors!!!
A lot of the relationships become more obvious when you compare two things. I often wonder if non avian dinosaurs di the head bob thing when they walked, or if they had a bassy chirp or cluck. Take a close look at German cockroaches and praying mantises some time. You'll realize mantids are just roaches sitting up on their fat asses.
@@BudgetFilmmaking
Indeed, roaches/termites and Mantis do make the superorder Dictyoptera
Birds aren't real
@@DelfinoGarza77 You aren't real.
I guess that is why chicken fighting is common in certain countries
Not bad, and the animations are hilarious!
There are modern birds with feathers on their legs and feet. I have some in the chicken coop right now.
Thanks so much for covering this topic which most media is ignoring i greatly fear for the future of life on our precious planet which we are destroying due to greed
This is fascinating.
Between 1000 of this sort of bird Is ONE like Y&M hidden
I will listen to Jeremy Irons narrating ANYTHING❤❤❤that smoky soothing tone and charming accent😉❤️🙏🏼great programming...love the Paleontologists from International disciplines.China has captured such evolutionary lines of plummage...can just imagine some species trying to fly in their test phase plums lol...plumes..yes❤i see bat and flying fox in taradactyl,chickens in the herd of herbivores,Emus in others...crazy😅😊❤
I bet feathers made those little dinosoaurs just adorable!
Appreciate the explanation, Robert!
Great documentary!
Thank you !
"Feathers on legs did not become a useful adaptation or survive into modern birds." Uh, pretty much all modern birds of prey (raptors, although not sn exact term) have feathered legs, even feet (owls!). Some more than others. Bald Eagles have capri "pants" of long feathers, but scaled lower legs and feet, as do falcons. Golden Eagles have fully, thickly feathered legs all the way to its scaled toes. They provide warmth, muffle sound for better hunting (esp silent owls), cushion and warm eggs and chicks when incubated and brooded, for protection, and probably other uses. I think there might be other species that have leg feathers of some kind, just can't think of any atm. I know more about raptors. I can't believe the writers made this huge mistake! Although it seems like a pretty good doc. But does make you wonder what else the writers left out, or why it wasn't reviewed by a scientist or at least someone familiar with birds.
Almost all birds legs are covered in scales
It's thighs are feathered, the upper part of the leg ...but not the leg or feet ...that's the difference
Sure there's going to be some outliers ...I think you'll find that scales predominately cover the eggs and feet of the majority of bird species
Almost without exception birds have scaled legs it's a byproduct of evolving from reptiles
I believe the feathers that they're talking about were actual flight feathers that proved useless
@@LemonLadyRecords the vast majority of modern birds have scaled legs ...the upper leg is called a thigh
And it's not the leg
Just picture the test flight in their evolutionary plums...lol
@@oftin_wong Oh darn it my thigh bone is part of my leg 🦵🏼 walking apparatus. I feel so dumb now🙄😉🦋🦋🦋
I often wonder in ancient tales in India, South America, China of feathered dragons or serpents that teach humankind new skills such as architecture, agriculture etc. Is there some kind of connection?
The winners were the clades that lost the bony tails because that made them light enough to fully overcome gravity and not restricted to gliding between trees.

Liked and shared.
20:03 bro went like “NOOOOOO! >:[“
Excellent video. Subscribed. 👍
Thank you so much !
Love the small hawk dangling from what nylon fishing line. Maybe a bit more of the budget should have gone into double checking before finalizing the work. At least the actual content is well done … 🇨🇦🖖🏻🇨🇦
The graphics are some serious Birdemic 3 creatures in the making.
Very interesting, but. Background music should be just that, in the background. At times the music was to the fore, making it difficult for older (87 in this case) people to always make out what is being said, spoiling a very interesting subject.
I find hearing difficult as well, but. I use headphones instead of telling obvious professional filmmakers how to produce their content.
My little Yorkie turns into a lion if I don’t give him his snack so I believe it😂
"My little Yorkie turns into a lion."
*Not gonna lie, when I read this my mind immediately thought of chocolate.*
😂😂 man just be making stuff up.😅😅
Archie was primarily a ground-dweller in an arid environment with few trees - documentary has problems in this respect - and their feet probably were not suited for sitting on tree branches - it is more likely they were very poor flyers as their anatomy strongly suggests, and basically ran along the ground while making short spurts of powered flight (to escape predators, for example)
Acheopteryx is no longer considered a true bird and is classed as Paraves instead. The first true birds evolved some 10 - 15 million years later.
@@posticusmaximus1739 that's only observed by those paleontologists who subscribe to that view - many others - the majority, actually - consider it a bird - not the 'first' bird - we will never know that
I call my chookies "tiny T-Rex"
How did politicians evolve into dinosaurs??
Bit of an insult to dinosaurs
I find it interesting that the theropods that became the most like young birds early birds evolutionary speaking were the Raptors those with the sickle claw on the on the back legs which if you compare it to a lumberjack with the Jack Spikes on their boots to climb trees or tree surgeons to climb the trees it seems that it's possible that there are early Raptors use that killer claw the sickle claw not to kill not just to kill but to climb trees or they literally run up the tree holding on with their front legs and slamming those claws into the tree trunks to gain purchase into the bark Get up and to get in the branches one to hunt snakes or other mammals that are up in the trees or to ambush attack from above in the trees down below on small animals medium sizing a little smaller than the Raptors It isn't pretty big Raptors I mean Utah Raptors huge dynamic kiss is huge even velociraptors huge compared to other animals lizards and such small pterosaurs that kind of thing now do we know that pterosaurs never made nested in trees? I don't know Who knows maybe that's what they were looking for is baby terrorist to eat or young terror sources are still learning to fly and we're doing small lives between trees
Why would the leg feathers evolve if they were non-functional?
Trial and error?
So, what now?
Some traits (e.g., leg feathers) are neutral; that is if there is no selections against them, they persist. Or, perhaps their advantage has yet to be determined.
why do you have whiskers? warmth? sensation? display?
How come CGI never shows theropod dinosaurs walking like chickens?
Was it really necessary to end it with the babies drowning? Sure, such things no doubt happened all the time, but what was the point? Did that add anything worthwhile or informative? Minor point but it soured my impression of the documentary.
Ikr so very sad and dramatic scene...poor lil buggers🧜🏼
⭐️awesome beautiful vid.
Thank You !
This was a great documentary! Very well done! The narrator was actually human, nice touch in a lazy "AI" period. Xu Xing is awesome too! I bet he is the celebrity paleontologist of China! Very cool guy, I think. 🙂
why are all the recent feathered dinos only found in China and nowhere else??
Got the vocalisations wrong: again.
BS!
What about bats, flying squirrels and platypus?
Why do film makers insist on making dinosaurs roar like big cats?
If birds are descended from dinosaurs, wouldn't they roar, too?
SMH
If birds had lungs the size of a T Rex , I doubt they'd be chirping.
@@shanemiller6982 Birds and reptiles do not vocalise in the same way as mammals.
While T Rex might have bigger lungs and may have vocalised at a deeper pitch, they still wouldn't sound like a lion.
Some dinosaurs evolved into birds that are around today. A diverse group birds and flying mammals too...bats/fly fox..chickens,pheasant,african grey,Emu,Ostrich,ravens...etc etc etc....Jeremy Irons❤❤❤
@@pencilpauli9442probably hiss...large reptiles hiss...😅
@pencilpauli9442 How is it that you say that? While it might no sound like lion , I imagine the giant lungs of a T Rex would bmore a roar than a hiss or chirp.
I still find it odd that ever so called dinosaur bird devolved from having teeth to a beak , and not 1 species of birds today have teeth 🧐🪶🦖🪽🦜🤔
The mystery here is why chickens no longer have ability to growl like a lion, and chase away any weasel or wolf in that way.
Theve been bred for many years now
Not about birds, but the Pangea continent does not make sense to me. It indicates that the earth was somehow formed out of balance with this large continental high spot in one place- that would make the earth wobble and shake. The current accepted theory of planet formation is that dust particles slowly combine together and gravity condenses them into a circular rotating cloud which eventually condenses into a solid with heavier elements toward the center . Under this theory the earth would have been a very consistent and round object balanced by nature.
O😂😮
At minute 26:29, the carnivore sees its prey and lets out a scream... That doesn't happen nowadays. As far as I know, all hunters are silent and don't alert their prey that they are coming for it. Where do they get the idea to do this in every dinosaur chase reconstruction? From the idea that they were stupid?
they were yet birds... the bones were caves, and the females brooded their eggs... even if they didn't fly they were birds, giants birds
Furry Dinosaurs--- how quaint!
What people fail to realize that Pangea was not as today. Well done
Someone who actually has a brain and uses it... wow I am very impressed, you don't see many people questioning all their lies propaganda and stupid assumptions. Great job
What propaganda
@@A.D.540 most of your stuff about Dinosaurs Is propaganda. We don't know much from back then and can only figure out so much from bones. Arc was a bird not a transition. Even the brain scan they did of it shows it had a birds brain.
What is your field of study?
@@moonshoes11 poking holes in evolution lol. Yeah seriously I have been looking into evolution for years now. It's a right mess more imagination then actual science. What science the can claim is usually full of flawed assumptions and arrogance.
@@vikingskuld
Oh, you’ve been “looking into evolution” for years? And *still* don’t understand it?
How do you counter Fossils, DNA, Biogeography, Anatomy, Analogous structures?
And let me guess, you’re convinced consciousness doesn’t require a physical brain, based on your “looking into” science?
Flawed assumptions and arrogance? How do you explain away novel, testable predictions?
Flawed assumptions and arrogance is more like believing there is a master of the universe who wants a personal relationship with you.
In other words, you have no formal education, but think you understand it better than those in the field of study who do.
Birds are Dinosaurs there are many types 🎉
They shared a common ancestor
But today ..we have modern birds with roughly 6500 significant physiological differences to their dinosaur ancestors
It always irks me when someone talks about the "strange creatures" of the distant past. The world is FULL of strange creatures that are alive right now. You think giraffes and kangaroos and Venus fly traps and cuttlefish aren't strange? And all those weird fish that live in the ocean deeps?
the fascinating bird to me is the Hoatzin. It is a toothed clawed bird from South America. Supposedly tastes terrible. Definitely NOT chicken.
Sounds fake.
@12:56 HOW do they know they nested in tree's?
“allowing it to hunt, and nest in trees”
@@moonshoes11 come again? ok it hunted , but how do they know it nested in trees?
@@bassbustingman
They didn’t go so far as claim knowledge that it nested in trees. They indicated that with its ability to flight, that would allow it to nest in trees.
Though we can use induction to conclude it is likely they nested in trees, as it being able to get to a higher location provided safety.
How do you know it hunted?
@@bassbustingman What is it with people like you? You see or hear about something to do with science, and instead of accepting it, you immediately ask the dumbest question possible, "but how do they know!?" They know because they've spent centuries figuring this stuff out, so please, stop asking stupid questions and show some damn respect.
When i look and learn about birds i see reptiles with wings, i learn how dinosaurs were and behave.
Ahahahahs
And entropy-says most of these silly guesses are false
Creationists need to learn something about science.
Please support your statement with evidence, such as fossils. Religious beliefs don't count.
Every example,we have of consciousness results from a physical brain. Physical brains came about after physics, chemistry, and biology.
Do you hold a position where consciousness could occur without a physical brain? And what evidence could you offer to make such a conclusion?
Entropy has nothing to do with this, or what you consider to be "silly guesses". Try again later when you know what entropy is.
@@paulford9120 If creationists learned anything about science, creationism would no longer exist.
Why would all dinosaurs shrink massively, lose all their teeth and grow wings?
This is just like when they told us all dinosaurs were cold blooded 😂😂😂
Not all dinosaurs, one group of dinosaurs. Not all dinosaurs were large, and the group birds evolved from were smaller.
As for cold-blooded, we thought they were at first, then we learnt more and realised that some were and some weren't. The group which evolved into birds were also one of the groups which was warm-blooded, which is why they had simple feathers to start with. Then the simple feathers became bigger as that allowed them to better incubate their eggs. Once they got big enough, they could use them to glide, then flap to prolong time in the air, then get better at flapping, and you have powered flight.
Not all dinosaurs, there are still crocodiles.😊
@@brenton2561 crocodiles are not dinosaurs, they are both archosaurs but archosaur is a bigger group than dinosaur. It's like cats and dogs, they are both in the carnivore group, but only dogs are in the canine group
@@samanthagibson5791 fair enough
I was told in school crocodiles were dinosaurs and they were all cold blooded im fed up with theoretical science its just someones idea and not proven why wouldn't dinosaurs be more diverse just as our animals are today?
Heres another example, "all dogs come from wolves" try breeding wolves to get a any other type of dog it is genetically impossible @@samanthagibson5791
Probably men Is thé descendent of THE Birds "branch"Revolution.
Fish-reptile-birds-mamals like you&me
Short honest answer, they didn't.
Evidence?
Dinosaurs evolved in a bipedal Mammal also ?
?
@@Dr.Ian-Plect ? ?
@@JohnTwelvegage Read your comment...
Many mammals (much, much later than dinosaurs) experimented with bipedalism, but we are probably the first great apes (hominids) to take up bipedalism full time. Mammals and dinosaurs have a common ancestor, so yes, and no? 🙂
@@dietrichess9997 What are you taking his comment to be stating that this "Mammals and dinosaurs have a common ancestor, so yes, and no?" answers?
At this point, I think it's prudent to conclude the following:
1) Warm blooded and cold blooded dinosaurs roamed on the surface alongside the mammals.
2) The cold blooded ones evolved into reptiles, the warm blooded evolved into birds.
Reptiles came first ...dinosaurs evolved from reptiles
Birds and other dinosaurs always are or were reptiles, like us. You cannot evolve out of your clades.
Most likely, it was small swimming dinosaurs. Swimming uses the wings the same as flying.
Did feathers come first? Or an evolutionary feature, not necessarily on ALL dinos; think of to days hippos//rhino s, with thick skin leather vs fur... or feathers!
Birds ARE dinosaurs.
Interested in yhe cotent but don't want to listen to that droning old bull . Bye bye
Birds remember, somewhere in their DNA, that they were titans once. With teeth and claws, where the mammal ancestors fled and hid before them.
And they desire a return to such a time again.
They didn't. Great fairy tale! 🧚♀️
Great mass of ignorance between your ears.
Over dramatized, low on facts.
So glad giant lizards become chicken, instead of being eaten by them they are now eaten by us and kept KFC in business.
Enjoy this cartoon.....it's about as close as you're going to get to a process that is mathematically impossible. Anything requiring a chance of occurrence greater than 1 x 10 to the 40th power is disregarded as never going to happen. (The similarities observed is because they are an optimum design for that particular creature and come from the same Designer).
The only evidence we have of any God is that they are completely imaginary.
Perpetuating the "mathematically impossible" fallacy.
Please spend more than 12 seconds on this point. Simply type that title into Google and see what you get (and read it).
@@JohnKSedor
Your argument only means you have no understanding of science, biology, and evolution.
Even the math is something you’re just parroting and don’t have the capacity to conclude on your own.
What is mathematically impossible is consciousness existing prior to physical brains. And we know brains came after physics, chemistry, and biology.
@@moonshoes11 You sir (or boy) are an idiot. I hold 2 Engineering Degrees & am going for my 3rd. I also hold a LSSBB (Lean Six Sigma Black Belt) which is extremely heavy on DOE's (Designs of Experiments) and I can tell you that Evolution fails completely in those fields. Honestly, rather than be embarrassed, spend some time investigating the preposterous odds that Evolution requires time after time after time. It's impossible.
the fact that lizard lay eggs.. the birds lay eggs too... its a hint thant it come from reptiles
Phylogenetically, birds are reptiles.
" ultra-realistic computer graphic reconstructions " This is the issue with Darwinism. They try to use subjective reconstructions to suit the idea of Darwin.
For real? Darwinism is based on scientific observation and research. I don’t understand what you’re saying - do you really mean that Darwinism can’t be true because someone made this video?
Another cartoon about evolution. Geeez...
Yes, it's almost as if there is an entire group of people who fail to understand evolution, and therefore require something as simple as a cartoon to get it into their empty heads. Judging by your comment, not even a cartoon can help you learn basic facts, how disappointing.
@@Dusk.EighthLegion Sorry, I go with mathematics and statistics and am completely surprised by how many people just accept evolution when it is mathematically & statistically impossible. Any event requiring a chance of occurrence greater than 1 x 10 to the 40th power is dismissed as never going to occur. And yet, that is what evolution requires almost every step of the way. Unbelievable that intelligent people don't investigate this more thoroughly.
@@Robert-pg2id It is neither mathematically or statistically impossible, your math is complete bullshit that you've found on the internet and parroted because you do not understand it, and if you were intelligent, you would have investigated this yourself and found it to be true. As it stands, you have clearly never investigated it, you lack understanding of what it is and how it works, and therefore any opinion from you can be written of as the ignorant ramblings of someone who doesn't know what they're talking about. Try again later.
@@Robert-pg2id I don't know where my comment went, but literally everything you say in your comment is false. Try again later when you learn how to be honest.
@@Dusk.EighthLegion Everything in my comment is absolutely true. If you submitted an Engineering, Quality, Manufacturing or Product Development Program with the same odds of success as Evolution, you'd be fired!! Do you even know what a DOE is? It's a Design of Experiments, which requires mathematical and statistical proof from multiple scenarios that a proposed idea will work repeatably and reliably, not minute chances of random occurrences that are beyond the chances of success. That is ridiculous.
technically, YES, most dino's have feathers - because since the end of the Mesozoic, there are just alone TODAY some 9,000 bird species - and over the past 64 million years there were many others, now extinct - DURING the Mesozoic, no - only the Coelurosauria developed feathers, and even among them, some did not - large tyrannosaurs, for the most part, for example - vastly outnumbered by the quantity of species of other completely-scaly dinosaurs
Dinosaurs all originate from Ancestors that had feathers. What's more is Pterosaurs also had feather like filaments. Further, Aphanosaurs that are basal to Avemetatarsalia also likely were feathery. Suggesting that earlier animals may have had feathers too. Feathers are very old.
@@posticusmaximus1739 NO NO NO. Who told you that? That's ridiculous - you'd be bounced out of 300 level classes very fast.
Sorry but no, most Dinosaurs DID NOT have feathers.
@@vikingskuld most non-avian dinos did not have feathers - but as far as DINOSAURS in total, yes! most do - because all birds have feathers and they are by far the most number of taxons
@@Scion-cy6wj there is a problem with what they call a feather. A filament does not count as a feather in anyone brain that uses common sense anyway. They call those filaments feathers and no they are not. So no T Rex did not have feathers. Most of the theropods I know of don't have feathers. Hair like filament found on some of the fossils may just be from decay. It's been shown to happen. The ones that we really know have feathers are birds. To say Dinosaurs evolved into birds is still just deceptive at best. There was a modern bird found that predates most of what you would call feathered Dinosaurs. Also a lot of places that make models of fossils will put feathers on them but that doesn't mean the original was found with feathers. There is so much interpretation in what a fossil would look like it can border on fraud. Look at all the Neanderthals and how for decades they were portrayed as apemen. Yet we know they were human
Birds arent real. The internet said so.
SLICE Imagination. Kindergarten science. Not the slightest clue about the complexity of even the simplest life. Just ignorant.
Please explain your statement and back it up, unless it has to do with religious belief/ancient mythology.
I always wondered why the dinosaurs aren‘t mentioned in the bible when everything else is - so: they are! Mentioned as birds striving the earth after the plants, „seafood“, fish and insects and before the mammals and humans.
Middle Eastern mythology is not an accurate record of natural history. Don't expect everything to be mentioned in every ancient written text.

Ok, done watching. But how do you explain that birds came from dinosaurs when you have the proposed feathered dinosaurs that are supposed tl be the ancestors of modern birds placed at as many as 120 million years after the fully formed and fully feathered bird Archeopteryx? How do you evolve into something that already exists?
How come there are no documented cases of anyone finding fossils of feathered non-avian dinosaurs until after the theory of a missing link between birds & dinosaurs had already been accepted by mainstream paleontology (Sinosauropteryx, China 1996)?
Archeopteryx has a clearly bird skeleton with a bird's tail and its balance point at the knees whereas Sinosauropteryx has a clearly dinosaur skeleton with it balanve point at the hips - if a bird like Archeopteryx (which, as all birds do, must walk from the knees which afe tucked into the body) tried to walk like a dinosaur from the hips it woulf fall over unto its beak. Seeing as how more than 30 out of 60 known "feathered dinosaur" species come from the same place in the Yixian formation in Liaoning China, with the recent case of the confirmed "feathered hoax" of the forgery behind the fraudalent Archeoraptor in mind aftrr being presented as an official "missing link" between dinosaurs & birds makes me wonder how many of these fossils are being checked for validity before their publications. A lot of the papers don't say if the fossils were excavated or simply bought - local farmers caught unto the fossil craze real quick and began selling fossils of their own to scientists eager to make a name for themselves on some article.
"Paleontologists have tried to turn Archeopeteryx into an earth-bound, feathered dinosaur. But its not. It is a bird, a perching bird. And no amount of 'paelobable' is going to change that".
Alan Feduccia, Paleornithologist

Bro, feathers have been around for 240M years. Aphanosaurs which were dinosauromorphs had filament coverings as did pterosauromorphs
@@Scion-cy6wjTHIS IS THE CORRECT ANSWER
Birds came from dinosaurs yes that's evident but saying dinosaurs were birds is just an excuse to make a provocative video based on speculative findings.
