The Origin of Birds - HHMI BioInteractive Video

- In the second film of the Great Transitions trilogy, paleontologist Julia Clarke takes us on a journey to uncover the evidence that birds are dinosaurs.
The discovery of Archaeopteryx in a quarry in Germany in the early 1860s provided the first clue that birds descended from reptiles. But what kind of reptile? In the last 40 years, scientists have identified many shared features between birds and two-legged carnivorous dinosaurs called theropods.
The film illustrates many of the practices of science, including asking important questions, formulating and testing hypotheses, analyzing and interpreting evidence, and revising explanations as new evidence becomes available.

18:14 That bird looks so shocked to find out he's a dinosaur.
Ty J
hahah he's like WTF so I'm a dinasaur then!!!!
Lol.... he was like HUHHH ?!!!!
18:14 That bird looks so shocked to find out he's a dinosaur.
Just imagine how you would feel if you make the same discovery... You'd be shocked too.
worfoz lol I was gonna comment that.
Feathers evolved because scales were so Triassic. No trendy Theropod wanted to be caught dead with them (and fossilized) in the Jurrasic.
Actually it is scientifically proven that all therapods have the potential to be feathered. Their earliest ancestor had feathers, therefore they all could (not that they all do)
your hair also evolved from hair just so you know
Try #Jeril Manikkadave
😄 gawd, apparently these other serious fuddy duddies don't like jokes
@@trvth1s uh, might wanna take another look at your comment buddy
I always loved birds since my childhood, but when I discovered that they descends from avian dinosaurs I loved them even more
'they descends from' ehm.. they didn't descend from avian dino's... They ARE avian dino's!
@@glennsommer8901 You're both correct.
ElVISFX Yeah me too. When I was convinced birds ARE dinosaurs - biggest paradigm shift ever!
they are descends from non avien dinosaurs and ARE avien dinosaurs
@@markgladney1836bruh they are -_-
9:17 Aww, cute doggy is waiting patiently for a bone.
Haha. Sadly for him, they're not looking for the kind of bone he can chew.
One of the best explanations of the relationship between non-avian and avian dinosaurs I've seen - - concise, clear and well-crafted. I studied with John Ostrom back in the 70's and knowing him as I did I can say he'd be very pleased with this presentation.
You forgot to weave into this the story of the Terror Birds, which filled the niche of tyrannosaurids and other smaller raptor dinosaurs.
I think their point was just linking extinct cretaceous theropods to modern theropods. Terror birds are still birds and they lived long after the dinosaurs, the last species went extinct relatively recent.
They did fill the same niche but terror birds, like all birds, had a major size constraint due to a lack of a tail.
@@trvth1s that's what always puzzled me. I mean, look at the peacock male. He has long and probably quite heavy feathery tail. Why can't terror birds have the same tails?
@@kempo79 Peacock males have a very short tail with long feathers. Not the same as a long tail made of muscle and bone. Long feathers are more like hair.
This Is great! I was embarrased cause yesterday I was atacked by a freaking bird, now I can say that a dinosaur wanted to kill me! What an experience! My kids will be proud of me when I tell them how I defeated that nasty therapod!
Let me guess, magpie?
@@lhaviland8602 I deny it!
Veeeeeeryyy good!!! Imagine onde doc like this but with 2 hours long and detailing the evolution of flight as well. It would be legendary. PLEASEE DO ONE :D
When i was in my first year in high school, science class, i told the teacher that birds evolved from dinosaurs. She said i was wrong and the other kids laughed at me for saying such a stupid thing. That was a loooong time ago (70's), but it burned into my brain for the humiliation of the experience and not being allowed to correct the teacher even though I knew I was right.
Dear Miss (whatever your name was)... I TOLD YOU SO!
To be fair, in 70s this hypothesis was pretty new. All started with discovery of Deinonychus in 1969
I want to be a paleontologist when I grow up I am 11 right now I love dinosaurs since I was 4 years old

You can do it! Dream hard and work harder and you'll find all kinds of new dinos.
Good for you you can do it study hard.
You can do it. Find your passion. I believe in you!
I loved dinos when I was a little kid and said I really wanted to be a paleontologist. Now I'm in college for it lol
That's exactly me!
So informative! Thank you so much for this. It really is interesting how birds came to be!
Awesome video!!! Thank you very much and congratulations on such an incredible work!!
Thank you so much for such an amazing video. 😍😍😍 I am also fascinated by nature specially birds and dinosaurs. I live in Alberta, CAN and here there are a few sites and museums about them. The first time I visited an exposition about dinosours I just started to cry, what an incredible detail. I am so thankful to people like you, that dedicate all their life to study and make possible for us, to have a glimpse at this amazing extinct creatures.
You cried with joy at the sight of their fossils. Luckily we can't see them in the flesh for we would be screaming in horror.
2:06 She's holding my fave animal of all time... I am so jealous.
seeing an animation of a dinosaur courting ritual is BLOWING MY MIND
Had to watch a video from this channel for school but now I'm invested and watching everything from the channel
Well made and informative. Thank you.
Great video! thank you a lot for the precious information!
That's truly awesome to know, great vid!
Many thanks for a clear, concise and visual explanation on the evolution of birds from dinosaurs.
13:26 The water isn't even going into the mouths in the model 😂
Yeah, I see this a lot in these sorts of videos. Your beak is cupped, just submerge it completely in water, then pull it out. Bam, 10 times more efficient.
Beautifully constructed, easy to listen to and watch video. Thank you :)
Fantastic and remarkable explanation. One trillion thanks for your videos and efforts.
You're very welcome!
Great video. Thanks for uploading!
Great video! Thanks for posting.
I commend the graphics. It's amazing.
What a fantastic video! Really well made!
Your face is really well made also
@@tommysuhlami6241 SIMP
Great video. I really enjoyed it.
Literally this video is so educational and interesting. Made me love my master's subject .
fantastic. Congratulations to HHMI
What a lovely and intelligent documentary
a very informative and amazing video regarding the fossil bird
One of the best!
Amazing science. Thanks so much.
i had to watch this vid for a science paper but dude i actually liked it and found it rlly interesting 😳
i can't unsee all dinos now as looking like little nugget baby birds. with their fuzzy sticking out feathers and it makes them adorable.
I use to hate the hell out of birds (except for hawks,falcons,eagles and owls), but nowadays as i researched, read and observed them, i now love them. All those years before as a kid i wondered about life with dinosaurs, not realizing that Iam actually living with them all this time, birds.
yes just how bats are mammals birds are dinosaurs
Awesome video!! Thanks!!
11:23 When my teacher calls on me in class
*surprised eagle face*
16:29 I initially saw this as *a duck as large as a shrimp boat!*
Beautiful video
Incredible!
Wow there is stunning diversity of Birds and there is more than 10,400 birds species
Sooo what you saying is a T-rex taste like chicken ☺
even crocodiles do
same with humans.
no, you taste like chicken to him!!!
Probably more like ostrich or emu...
Noodly Appendage
Human Flesh taste like 75% Pork & 25% Beef, yum!
Thanks for sharing. Awesome video
simply wonderful . congrats !
Many thanks!
Really good!
Very amazing, interesting and informative.
Glad it was helpful!
Uggghhh my ornithophobia was killing me while watching, but this was so damn interesting.
Why the fear?
Next time you watch a lovely dove you just have to remember it's a tiny velociraptor walking towards you. Fascinating!!! 😈
9:50 don't try to fool me, we all know that's an old banana
Lol
The differences between bird and pterosaur wings are fascinating.
AMAZING ❤
So good ❤️ loved it.
Great, just great video!
spectacular
id love to learn about how internal temperature regulation developed in dinosaurs and birds
well, after meteor hit and global climate catastrophe u either develop self temperature control or get extinct
komi sar
Well, not exactly.
Dinosaurs already had temperature regulation long before they went extinct, and the evidence suggests they were active sort of “warm blooded” animals that also had characteristics of cold blooded ness.
It’s possible that the smaller more active carnivores like the Dromaeosaurs were already fully warm blooded like birds, after all, we have evidence of complete feathery covering in them and we know they were very closely related to birds.
It’s still not yet known, though.
Very interesting fact .thanks
It is so cool to think that one branch of the dinosaurs still lives on. From the emu to the tiniest hummingbird, our avian co-inhabitants of earth are...birds!
Birds are perfect magic ❤️the most amazing animal on Earth 🌎
What kind of bird is that at 17:27?
Does anyone else watch these for fun? I've seen these videos countless times
As a child I was reading an illustrated book about dinasaur tracks.
Finding tracks in the soft sediment while exploring a stream with my older brother I called out there were dinasaur tracks.
He came to see saying they were bird tracks.
They look almost identical.
I said birds are dinasaurs. He laughed.
I always thought birds were dinasaurs.
I have doves and watch docs with them looking on. When we see dinasaurs I tell them they are little dinasaurs. They like it.
Amazing video
Thanks!
18:18 an unnecessary eagle sound for griffon/bearded vultures' soaring footage.
Not even an eagle, but a freaking red-tailed hawk's sound!
thanks for this
You're welcome
December 2017: Re-examination of the ' Haarlem Archaeopterix' (Teylers Museum, Netherlands) it is now a new species. Ostromia Crassipes.
What about Aussie birds, I heard in recent times there is research on mamy of the worlds birds originally migrated from Oz.
dinosaurs are still with us !!! we just call tham Birds👼👼
Preach
but not all birds taste nice believe me some are even piousness
Except chicken please dont eat birds. They are beautiful and i have a parakket. Eating birds just upsetting me 😟😟
Dinosaurs went extinct because they tasted like chicken. Some could fly away from us and survived. Ostriches could run too fast.
Actually I still prefer to think the event was a colossal solar sneeze. North Pacific as ground zero.
Which museums are the fossils at???
So how long could a massive dino bird have survived and do we have the last dragon story yet
Avian Dinosaurs are beautiful, multifaceted animals. Here's hoping they'll always be with us.
Do the genes that create scales in a reptiles have any resemblance to genes that create feathers in birds?
yes, and those are the same genes that create hair [fur] in mammals [fur and hair are the same thing].
Birds still have scales on their leg.
Yeah, and in fact, the genes for producing feathers in birds and scales in crocodilians are homologous to each other, and a slight modification of the genes for scale production in alligators can produce elongated scales that resemble the primitive feathers found in some dinosaurs.
Genes can work in different order and timing and create drastic changes.
Science! IT IS AMAZING!
“Several different groups have wings” it’s three, only three extant groups have wings that can be use for powered flight.
several means more than two but not many, nothing wrong with that statement.
what kind of bird is that during the end credits?
i believe its a falcon
My mom sometimes called me "bird brain."
That's actually a compliment. Avian dinosaurs pack much brain complexity into their little heads. They are smarter than generally given credit for.
Now we just need someone to re evolve a bird into something like a dinosaur
This was excellent!
Oh yeah, man. Hey, I got this bridge for sale!
From now on when trying some new food for the first time, when describing it I’m gonna say it “tastes like dinosaur”.
9:14 I don't understand this diagram since an archaeopteryx was before the tyranisaurus rex. the rex was in the cretaceous and arch was in late jurassic
Birds evolved from some theropods, others were larger and evolved in other ways leading to the giants like T rex, contemporary with many kinds of bird. .
Theropod is a very a broader classification, archaeopteryx is a branch of theropod called maniraptoran. Birds are direct descendants of maniraptoran dinosaurs. Theropod -> Tetanurae -> Maniraptora -> Avialae (Birds). Tetanurae has two branches -> Maniraptora (e.g. Archaeopteryx) and Tyrannosauridae (T.Rex).
2:23 I wish someone looked at me the way that bird looks at the lady
Real samurais drink strawberry milk May be adopt a parrot. They are amazing creatures 😉. Pineapple conures are extremely sweet.
I know how you felt, bro!!
It was watching at her neck. That bird wanted to kill the lady... Not my ideal of romance, tbh.
I love dinosaurs and birds.😍🥰🦕🦖🐧🐦🕊🦅🐓🦃🐔🦩🦉🦢🦆🐣🐤🐥
Very helping educational vedio
Glad you think so!
As they now think that birds evolved from dinosaurs. Well is it possible that dinosaurs had a dawn chorus?
Around 12 minutes I was like finally, feathered dinosaurs
The oxygenation benefit of dinosaurs' hollow bones lends further evidence of endothermy.
While most intelligent folks are busy making money and gaming the system, paleontologists are content figuring out how dinosaurs evolved into birds. Such a warm feeling!
if you take a scale a stretch it out,
it becomes a feather.
Bird likes this presentation.
Origin of birds is simple. Julia Clarke and i mated.
BIOL 300 gang (we are watching this and doing a worksheet).
Cool.
Everyone should own a macaw, blue & gold, scarlet or blue and you'll learn first hand the evolution of the birds.
I can see the theropod relationship as a branch, but I don't know that I buy the co-option of feathers for flight. That's a pretty extreme conceptual leap of reasoning. What if birds are a branch evolved from another group of feathered reptilian/theropod water species able to fly short distances. The real issue here is the evolution of flight and it didn't just happen. Swimming to flying is a "huge leap."
archeopteryx was likely a glider it did not have the chestbone for powered flight at least for long distances
Early birds that "flied" well they didnt really fly they glided and gradually they adapted for actual powered flight
But when did the bird's beak appear??
the beak's always been there . I mean, frikkin Triceratops had a beak, as did Duckbilled dinosaurs and many many species of extinct dinos
well look at that dinosaurs/birds are the most beautiful animals alive today
Wow
The audio is not working, am I right or is it just me?
No problem for me with the audio, 2 years after your post.
As you can tell from the other comments, it was just you.
Man seeing a thumbnail: "I alwayse wished one would tell m... Oh! Bird birds..."
Birds ❤
