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)
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!
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.
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!
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.
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.
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
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.
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.
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.
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.
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.
3:34 Can anyone tell me is there a name for this particular Archaeopteryx fossil? It looks so beautiful, I kind of want to see if I can find a poster of it or maybe even a replica.
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!
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!
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).
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."
Very interesting. I hope you and BioInteractive will adopt a standard whereby ALL your video descriptions contain direct links to open documents, resources, groups, projects related to the topics presented. I left a voice mail. If you add $Thanks, then visitors and viewers can support and encourage presenters, and the organizations who support them. There is currently no way to support individuals separately. If authors, editors, producers, researchers, curators, anyone involved were listed at part of a visible and open "Team" then they can be encouraged as well. I can only suggest. But it would transform Internet education, if everyone who posts materials always gave links to open, complete and traceable background materials. If you wrote a paper for a peer-reviewed journal where you might get a few ten thousand readers, the editor would not allow you to publish without clear and usable references. On the Internet the links are the references that hold things together. If you send people to broken links that is bad. If you send people to "pay-per-view" that can eliminate most of the 5 billion people in the world who use the Internet is some form and most of the 2 billion kids from 4 to 24 I call "first time learners". So "open" and really accessible (not in name only) materials in formats that can immediately be used. I cannot write it all here. I just hope you all will set a good example for others, encourage groups to spend time to document what you are trying to share. If you give no links, the exploration stops dead. If you give links to generic pages unrelated to the topic, that slows down the process of discovery and self education. Today's Internet is more about learning, and global collaboration, than showing off how much someone has memorized. Help people learn how to learn on their own. Sorry to preach. This is the 25th year of the Internet Foundation. I did not plan on getting so old so fast. I can only hope the few groups I can contact learn that 8 billion people using the Internet for most aspects of life means NOT putting barriers or inadequate signs and directions. You know where things are. Today I see 387,853 views on this video page. And every one of them might well want to know more. But the path you laid is full of delays and stumbling blocks. Same for all these videos. Thank you and cudos for sharing, shame on you for not thinking it through how many people might want to know more, and you did not do a good job of that at all. Think of 387,853 each having to spend 5 minutes to search for you and what you have written. Or spending an hour to search for this general topic. You can shorten that tremendously. The cost to society of delays on the Internet is larger than the total global GDP. In lost opportunities, it might well be many times larger. Because people see something that might be important, but cannot find what to do next. When the author and site sponsors know those things, I can only say it is a shame. A horrible waste. You can use $32 per hours (US GDP per capita as a very rough proxy of the cost. For "only" ten thousand of your viewers wanting to know more each probably having to spend several hours to recreate what you know from the words alone - faced with horrendous duplication and badly documented sites on the Internet - they might spend several hours each (say 5) so that becomes $1.6 Million lost time. You can do the numbers. Once you and this group realize that every viewer's time is valuable. And every second wasted is a loss. Do you really want to charge your viewers all the time it took to find, learn, organize and try to use what you have learned? If you need money, ask for it. But do not save yourself a few minutes at the expense of hundreds of thousand, millions or billions. Thank you. If you do not want this here, do not preemptively delete it. Simply reply and ask me, and I will remove it. Asking is collaboration, deletion is a form of censorship. TH-cam can allow discussion, collaboration, community, communications, sharing of things other than a few video formats. It could be wonderful global educational sharing and learning place. But it is clumsy, has no recommended best practices, no groups working openly to improve things. No volunteers to help new groups. There is much that can be done with care, kindness, a fair degree of flexibility. You are teaching the whole world. 8 Billion people ("everyone" if a few people get their act together) . I would not write if I did not think you are doing a good job. You have the potential to help many, with just a tiny shift in your time and priorities. It takes little for you to point the way - explicit and tested pathways. Not just to sponsors and friends. But to the whole of the topics openly shared and collaborated.

A common argument against biological evolution is that the theory contradicts the second law of thermodynamics. The second law says that disorder, or entropy, always increases or stays the same over time. How then can evolution produce more complex life forms over time? The answer is that the second law is only valid in closed systems with no external sources of energy. Since the Earth receives continual energy from the Sun, the second law does not apply.
Petern Sheen you are correct I was wrong about entropy and evolution...thank God for science...I was simply trying to say that lifeforms as they become more advanced they seem to be evolving to a more compact form becoming increasingly efficient in use of energy in the system an inevitable consequence of evolution...I would think this would have happened with or without the rock...all we have to go on is paleontology...biology....microbiology...geology and yes geophysics...I'm sure that the totality of scientific evidence empirical or otherwise will eventually reveal this mystery...
Bingo. People just don't get what thermodynamics means. It basically means the universe is running out of heat over time, but until the sun dies, the earth is constantly given new energy for thermodynamics processes (aka heat). It has nothing to do with order/disorder, it's about useful energy for heat processes. Creationists can't comprehend that, so they pretend like it's literal disorder. Too funny.
Noodly. It means the universe is going to freeze to death( a la ending of "The Shining")? Creationists may comprehend stuff, but their vested interest in "faith" blocks their reason.
small pterosaurs, late cretaceous there were still many large pterosaurs, some of the bigger ones filled niches which birds have never filled [nothing had yet]. Pterosaurs are extinct but they are still thus far the most successful flying vertebrates in history. They also had the most efficient flight that we know of in vertebrates.
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.
18:14 That bird looks so shocked to find out he's a dinosaur.

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)

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.

yes just how bats are mammals birds are dinosaurs
Fantastic and remarkable explanation. One trillion thanks for your videos and efforts.
You're very welcome!
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

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.
Wow there is stunning diversity of Birds and there is more than 10,400 birds species
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.
Many thanks for a clear, concise and visual explanation on the evolution of birds from dinosaurs.
Literally this video is so educational and interesting. Made me love my master's subject .
I commend the graphics. It's amazing.
Beautifully constructed, easy to listen to and watch video. Thank you :)
Does anyone else watch these for fun? I've seen these videos countless times
16:29 I initially saw this as *a duck as large as a shrimp boat!*
Uggghhh my ornithophobia was killing me while watching, but this was so damn interesting.

Your face is really well made also
@@tommysuhlami6241 SIMP
“Several different groups have wings” it’s three, only three extant groups have wings that can be use for powered flight.

Everyone should own a macaw, blue & gold, scarlet or blue and you'll learn first hand the evolution of the birds.

Well on an evolutionary point of view they are
And reptiles are modified amphibians who themself are modified fish

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.

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
Which museums are the fossils at???
what kind of bird is that during the end credits?
i believe its a falcon
Great, just great video!

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.
