385 million years ago, a group of fish would undertake one of the most important journeys in the history of life and become the first vertebrates to live on dry ground. But first, they had to acquire the ability to breathe air.

Me: Wondering if my ancestors are proud of me
Tiktaalik: *flopping noises*
Eusthenopteron: *heavy breathing*
Just be more optimistic: one is trying to clap and the other can hardly gather its breath because it's so emotional about your success!
Ah yes fish go brrr brr
Flip it actually
The list I mean
Nvm is fine
FLIP IT
they're so proud of you for doing what they could not. Breathing air effeciently
this was oddly very moving
The first fish to breath was Like "dis some dry water"
xSurg it do not matter
So I told that girl I'mma slaughter this
xSurg Gordon Ramsay fish: BLAND!!! NEEDS SEASONING
Fish: (Smacks fishy lips) needs water
🤣🤣🤣
That first breath prolly hit different
Probably was the first biggest dopamine rush to push neuroplasticity enough to say change to the land resistance.
🤣
n that first fish was just built different 😤💯
Yeah the oxygen hit different back then
Probably grew faster when it got a whiff of that air
One small step for a fish, one giant step for animal kingdom
It’s been 1 year and no one replied to this masterpiece of a comment.
*that changes today*
Niel Armfish
😂😂😂
I wonder how they might have developed that organ on their skull to breathe oxygen while the whole body is underwater (which helped them do stuff with mouth underwater)
Man there is not a second in these videos where I get bored or distracted.. wow!
I get distracted by the tattoo, (in a good way) I want to see the full tattoo. it looks really nice
Agreed Legosaurus
For today standards is 10 minutes of focus sort of maximum capacity than XD
I get distracted by the tattoo in a bad way. Because it makes her seem less intelligent for me. Real nerds don't have time for time consuming tattoos XD
i was bored the whole vid
everyone take a moment to appreciate the fact that if this fish didn't take one for the team and walk onto land, you wouldn't even be here rn
Yeap that is good scifi theme
Just by one little stroll on the land TH-cam came into being
that first fish was prolly just took a walk to clear his head
Wait so was the fish male or female?
stupid fact not true fact, funny how educated even gotten as human lol
Fish: *breathe in*
Also fish : *is now the ancestor to a huge group of animals*
TETRAPODS

I am staring at my hands and fingers after having a realization that they are modified fins. Evolution is amazing.
Don Lasky 😂😂😂😂😂😂where’s the proof?! Where are the missing links? Have we seen star dust turn into humans or a monkey evolve into a human?
@@sebastianmireles6691 Most of the questions you asked are common and are answered on this channel so stick around. Have an open mind and you don't have to to believe everything.
Words lack the capability to explain how much i laughed at your level of brainwashed slaveness
@@sebastianmireles6691 more proof then gravity. There is no missing link the science community can trace human evolution quite far. Evolution =\= abiogenesis please learn those two words. And yes we have created RNA the precursor to DNA in a lab using nothing but mineral rich water and a zap. We haven't seen monkeys evolve into humans because we didn't evolve from modern monkey. We have a common ancestor that was a precursor of monkeys and apes. Its 2020 man there is no reason to be this uninformed.
@@sebastianmireles6691 Even if we found every animal that led to humans, you'd probably move the goalpost and ask for more missing links. The proof is in our own blood. Some humans have neanderthal in their genes and are living proof of what used to be.
Here to learn about breathy bois
Swimmy breathy bois, specifically
Broken Wave moist breathy bois

“ You darn young Millenial fish, trying to breathe air above water. What’s wrong with you?”
"Back in my days we didn't have some fancy lungs and stuff. When oxygen levels in water were low we just swimmed somewhere else!"
Okay, will you learn to walk if there’s plant up there?
“Maybe”
Said some bugs.... and fish
Bill wurtz reference?
@@Damnnthatscrazy yup :-)

I still want to live in the ocean
That's fine. The ocean is quite nice.

:)
Well look at whales and dolphins. Mammals decided land wasn't so great either.
Broken Wave
Haha exactly. If only I was them
Imagine going back in time (I know this isn't technically ever possible but just imagine) and you have no food, so you see some fish on the beach. You stab a fish with a makeshift spear then disappear completely. That fish was your ancestor. lol
If you have that type of luck I wouldn't go playing Russian Roulette anytime soon
But you need more than one fish to reproduce......
Actually going back in time is KINDA theoretically possible, but not coming back lol
I wish I wish I hadn’t killed that fish.....
Evolution happens over generations on entire populations
Legs are just bony land-fins
Got it in one!!!
😀
And teeth are just scales for cutting food
Fins are just boneless(kinda) legs
Not anymore
Why would you say something so controversial yet brave...
It’s crazy thinking that one of my grandads is a fish!
Cuz they werent
@@whiteswordwarrior9995 right. More like great great great^500 grandads. Still it is crazy to think that our ancestors were fish. But tiny changes overtime translate into big changes. Just hard for some people to conceptualize.

ownership of bronchi is theft
Yeahhh no.
SIEZE THE MEANS OF METALOBISM
Destroy the capitalist gills!
Well every animal breathes oxygen even fish
Please show about how arthropods change from live in ocean, become live on land and breath air. Also another video how sea snails become land snails.
Actually, it is now thought sea snails first became river snails before becoming land snails
Breathe, not breath.

@@petergray2712 wooosh
@@petergray2712 So why exactly did they proceed onto land if there wasn't even lawn to mow?
How about you give us an episode all about plants? They don't get nearly enough attention given how important they are
Yeah, they do. I mean before animals started living on land on a larger scale, plants could grow and live without any competition besides themselves. Partialy being a cause of the higher oxygen levels from the carboniforous.
And how could there be herbivores if there were no plants. I can go on for hours about your comment being right.
Jimmy Siwik
Omg yes..... I totally agree, people don’t appreciate plats like they should
@@petersalucci5444 *ah yes. Plats.*
plants were vibing till these damn animals had to come and ruin everything.
That's because, you could collect the evolution history of animals through fossil ( bone remainings, mummified in mud, volcanic ash ect...)
But in the case of plants they easily decompose within days. Then how would they survive for millions of years?
For anyone interested in more on this subject, there is a popular easy to grasp book, called "Your Inner Fish", by the leader of the team of researchers who discovered Tiktaalik, Neil Shubin.
It is well worth reading and does not require previous exposure to the material to understand. It is written for a general audience.
She’s my favorite narrator on this channel. You can see the enthusiasm she has for this topic.
I love how this channel gets me thinking about evolution in more creative ways. There’s certainly room for a story about a kind of unique almost fantasy world in which evolution followed a different path and we see unique creatures that could have existed.
May I introduce you to "speculative evolution"? It's a fascinating branch of science(fiction) I've recently discovered. Try searching for the channel Curious Archive, especially its 4-part series on Serina
This channel would have made my evolutionary biology class so much interesting. Thank you PBS Eons!
I remember that. I was there. I had no idea what they were doing.
Remember darymaur? Miss that fish. We were buddy's at school.
What a great presenter! I've been looking for tetrapodamorphs in Pennsylvania with my son for the last 10 years. We even have a post parietal shield (posterior and dorsal part of head) from a descendant of Eusthenopteron which does have the spiracle right where she said it was.
There is much evidence that the vertebrate lung originated from a progenitor structure which was present in bony fsh. However, critical basic elements for the evolution of breathing in tetrapods, such as the central rhythm generator sensitive to CO2/pH and the pulmonary surfactant, were present in the lungless primitive vertebrate. This suggests that the evolution of air breathing in all vertebrates may have evolved through exaptations. It appears that the capability for proliferation of alveolar type 1 (AT1) cells is the “critical factor” which rendered possible the most radical subsequent innovation-the possibility of air breathing. “Epithelial remodeling,” which consists in proliferation of alveolar cells-the structural basis for gas diffusion-observed in the alimentary tract of the gut-breathing fshes (GBF) has great potential for application in biomedical research. Such a process probably led to the gradual evolutionary development of lungs in terrestrial vertebrates. Research on the cellular and molecular mechanisms controlling proliferation of squamous epithelial cells in the GBF should contribute to explaining the regeneration-associated phenomena that occur in mammal lungs, and especially to the understanding of signal pathways which govern the process.
Yeah no one's reading that wall of text buddy
@@matttzzz2 Yes I agree with you. But, I have described what happened before the first breath. Best, Leszek
@@matttzzz2 I am
Yay! I've been waiting for this episode! I loved it!!
Fun paleo fact: Eusthenopteron is the earliest known vertebrate that we know for sure had bone marrow.

GEEK! 😃
"Fish couldn't move to dry land, not yet." Fish today- "Why we still living in the ocean?"
It is selectively advantageous to stay in the water, but we do have fish like blennies, mudskippers, and lungfish
BECAUSE THE SUN IS A DEADLY LASER!
In fact if today's fish tries to leave it will be killed in seconds by humans or birds, at that time there was no such thing, so they were able to leave, and then they ate other fish that tried Get out
@@Lucas-zx9dr In fact is funny when humans try to imagine many various scheme for that complex area Livingzone
They missin out m8
Someone must have told them they were now breathing manually
Thanks Tiktaalik for going out of water. Now I have to work on jobs to pay my taxes until I die.
Fish trying to evolve for life on land: "Swim bladders... Eureka!" j/k
Swim Bladders. I never would have thought lungs came from swim bladders. Amazing.
@@JohnSmith-xi2ew I was looking for a comment like yours.
You guys are an inspiration
PLEASE CAN YOU MAKE A VIDEO ON THE ORIGIN AND EVOLUTION OF INSECT FLIGHT!
Abdul Karim Ismail I agree it would be great, but I also would appreciate it if they went deeper nd explain the entire origins of the first insects,
Good pun! "Inspiration". Haha.
Abdul Karim Ismail They made this very video this week!
Dareoth I know it's great!
I always have trouble keeping up with the time periods mentioned in the channel. I think they should appear visually in the video.
Thanks to a fish I was given a life I never wanted.
Fatherless figure here!
Fish are so dumb, like just breath bro its not that hard
TheKingGuardian I do it all of the time
Joseph Sivits
Haha I know right...... I’m a natural when it comes to drowning 😂
I thought everyone had the ability to understand jokes this simple.
I was wrong.
So you're Aquaman??
TheKingGuardian r/wooosh
How old are all the other organs we have today? Is the lung our newest organ?
Paul Paulson doubt it I would assume the ones we need for land are the newest since lungs came as soon as our ancestors came from the water
I don't know if we share enough between our skin today and that of any ancestor but some say its the largest organ and you could also consider it the youngest one
The newest organs are probably the ones associated solely with mammals, like the placenta, breasts, or fur (hair). I'm not sure if fingernails count as an organ, but those are just a primate thing, and I think the first ones appeared about 50 million years ago.
Its kinda hard to say because an organ slowly changing functions like this video depicts is not the same as an organ randomly appearing out of nowhere. When I heard your question, the first thing I thought of was the dropped larynx in humans in order for us to produce speech.
The prefrontal cortex of our brain is only a few million years old.
Pretty cool to thin that the legs we walk on today originally came from modified fins that lobe finned fish used to walk through shallow water that was probably rife with plants and other debris. And the lungs that we breathe through originally came from modified swim bladders whose function shifted from regulating buoyancy to taking in oxygen directly from the air. Evolutionary biology is immensely fascinating.
i want to thank you pbs eons for teaching me many new things. you are the best
I think of it not as breathing air, just needing less water. The insides of your lungs are quite wet as they need to be for gas exchange to occur. Gases (such as oxygen) dissolve into the moisture of your lungs, continuing to transfer into the water in your blood, CO2 goes the opposite way. We air breathers keep a bit of water with us, coating the inside of our breathing organs.
380 mil years ago: water water everywhere, not a drop to breathe
Shivam Shukla air isn’t a drop. You can’t have a drop of air...
dude who likes dinosuars but water can be a drop. Fish really would not know gaseous air. Do they even need gaseous air, given that its actually Oxygen they need?
dude who likes dinosaurs - Topic if a little water falling is a drop, why can’t a little air rising be a drop?
@@annonimooseq1246 drops of air are called bubbles
Nice Rime of the Ancient Mariner referance
Evolution is beautiful!

May our scaled overlords rise up from the deeps again and claim what is theirs by right!
P K didn’t work out that well for Team Aqua, eh?
We are the ones who rose from the depths and claimed dry land, fish are the ones who stayed behind and were lame.
Insects got up here first, the land is theirs, we just stole it from them.

Watching these videos about times so so long ago helps me cope with the current state of the world. Thank you guys.
Beautiful Oddity Yeah, actually, I am. Something about children locked up in cages screaming, wailing, and vomiting disturbs me. If you think I’m pathetic for having sympathy for children, then absolutely, I’ll wear it like a badge of honor.
Nick C So you cope with it by watching videos about fish? Instead of maybe trying to help them?
Bryan Wheelock Stress relief is an important part of daily life and self-care. It avoids burnout
What could he do? What are you doing to help since you think we should?
Gives you perspective, right?
Also, the ability to breathe air gave an evolutionary advantage: being able to escape predators. In time, the ability to remain longer periods of time in land, became the standard, as fewer species returned to land, since there was more availability of food in land, filling the required niches in nature.
I would love to see an episode talking about reefs, and how their composition changed over time (i.e. bacterial mats, stromatolites, rugose, tabulate, and scleractinian corals)
I have never felt so grateful for my lungs before. It is indeed good to be able to breath air.
bruh this guy started to breath air and now i have to pay taxes
I love her. Such a great narrator. I am absolutly enthralled the whole time.

Great, now I can blame with more precision the fish whose actions derived in me having to work tomorrow
I really love the prehistoric life. Thanks Eon! 😊😊😊
2:47 *PUSH IT BACK IN!*
I can see Ned Flanders going back in time to stop this from happening.
Can u explain this joke please?
I like how she says that we should give this fish massive thanks, because it's the reason we are here today, while I have seen memes of people being *angry* at this fish (same image and all) because it's it's fault that we are all here now stuck in this situation and we have to endure all of this lol
I have been watching a lot of Eons-videos lately, and this is now my favorite channel on TH-cam.
As always I hope you make more videos about dinosaurs. Especially if you could talk about some of the latest discoveries that have been made: new species, feathers/colors and so on.
Or, you know, just a documentary about the Diplodocus or something :D
Your channel is one of the best! It is so great!
I agree
I surprised myself liking the video during the ad, even before it started.
Thank you!
strongly agree.. really high quality!
I agree as well
These videos will never get old. Fascinating!
Thank you fishy ancestors! You made us humans what we are today.
I'm going to celebrate by eating some sushi
I thought swim bladders derived from lungs no the other way around. Great video by the way
That's what most evidence I know hints at, yes.
You should do an episode about Miguasha! It's one of the best fossil bed in the world, maybe the most diverse from the Devonian, and is now a national park open to the public in summer, with a comprehensive museum adjacent to it. I went there and it was incredibly fun. I'm sure they would let you film an episode if you ask.
I love Eons, it's such an interesting and concise explanation of our fascinating history. Thanks for another great video!
0:22 a she said "was about to go its own way" I started to hear Fleetwood Mac singing to the fish, encouraging it...🎶🎶 "You can go your own waaaaaaaay" 🎶🎶🎶
Thank you talking about the window of fish breathing air and from a while length ago.
I’m so glad to fossil leads help explain a window of history from amphibious toward mammal level transistion(s) has a way to measure our path histories.

sorry for bad english :/
No need to apologize and your message was clear.
idk why I'm saying this but hello
I would like to see episode about THE FIRST ARACHNIDS ot when INSECTS CONQUERED LAND. We have so little info about invertebrates evolution! I'm curious what ancient spider looked like!
They have a video on the eurypterids already.
I love how that fish took a breath said, “Noooppppee.” And dove back in.
I absolutely adore this channel!! Makes me remember why I was so split between biomedicine and paleobio! Might end up going back to class in a few years to study paleobio again :D
So uh what happened 💀
Twenty three thumbs down from people who aren't getting enough oxygen....to their brains.
Lmao
You guys really put the “eon” in Patreon 😂😂 I’ll leave now
This gives “plenty of fish in the sea” a whole new meaning
I can't believe you guys got this one wrong, most people believe that the swim bladder actually evolved from the lung, not the other way around. If you look at embryonic development the swimbladder starts as a lung before it pinches off from the digestive tract. Young fish must rise to the surface of the water to fill their swim bladders with air before the pinch off. Moreover, in primitive fish the link between the swim bladder and the digestive tract is retained, and these fish can constantly refill their swimbladder with air from the surface. The least derived fish have lungs, or no swim bladder at all. The lung came first.
I bet he accidentally smelled a burning fungi turning it high
Could you please make make video on the history of blood and it’s modern traits. I have consistently gotten many hundreds of likes on previous videos so this is a very popular question
Popular doesn't mean it has the potential to be very interesting.
Napishtim psh, everything about biology and evolution is interesting
Napishtim With the Eons team with their boundless passion and expertise; I have no doubt that they can deliver great quality educational and enjoyable videos as always. I mean many of Scishows videos fit the above while having otherwise mundane questions and answers
"Have consistently gotten many hundreds of likes"

Comments on how a comment has less than fifty likes. I look up to see more than fifty likes. Joking aside though, the comment is only a day old as of now. Give it some time, it appears that the rate he is currently gaining likes, it won’t be too much longer before the comment proves true.
Imagine going back in time and saw a fish on the beach and for no reason you kicked it and changed the whole evolution and now youre immune to kicking
thank you fishes for leading us to land where we live now today :)
I just wanna say, i love your channel and videos, history fascinates me, and you guys always deliver! I hope to one day make a career off of studying the history of our beautiful earth, thank you so much, you all make me so happy:)
This is a fantastic channel. I've previously been more interested in physics than biology, but the subject's fascinating. Thanks :)
I have recorded fish that seem as interested in seeing people as people are to see them. They even turn their heads slightly to follow someone. I post them as I get them so people can see it.
We always hear about how vertebrates transitioned to land, but never about non-vertebrates. I'd love to hear about the sea-to-land evolution of arthropods, molluscs, annelids, etc.
Love every video you make. This will surely be no exception
Great book recommendation for fans of this video: Your Inner Fish by Neil Shubin
