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.

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
🤣🤣🤣
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
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)
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.
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 RUclips 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*

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
“ 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!"

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.

Well every animal breathes oxygen even fish
the mudskipper :O :O :O like watching evolution happen
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
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
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?
"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
I always have trouble keeping up with the time periods mentioned in the channel. I think they should appear visually in the video.
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.
@@grantrobinson8179 no one cares about how this guy spell things
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.
Someone must have told them they were now breathing manually
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.
This channel would have made my evolutionary biology class so much interesting. Thank you PBS Eons!
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.
You know the ocean has hit a low point when fish got sick of it.

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.

Fun paleo fact: Eusthenopteron is the earliest known vertebrate that we know for sure had bone marrow.

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.

Thanks to a fish I was given a life I never wanted.
Fatherless figure here!
I want to know what footage that mudskipper crawling out of the water is, for memeing purposes! Perfectly describes how I feel when I get out of my house to go to work.
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.
@John Smith I was looking for a comment like yours.
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!
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)
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?

The sea was salty.
here, take my thumbs up
at least here on land salt is just right ✋😔👌
Some fish crawled out of the ocean and now I have to work and pay rent, lol
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.
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.
May Chthulu rise and his madness claim us all.

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
Love the camouflage on the different mudskippers. Very interesting how fish developed 4 limbs on land.
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.
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"
-Got less than fifty on this very comment
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.
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.
This channel is fantastic! Please keep them coming!
Lovely video. So informative, direct, and simple. Thank you as always.
Favorite science channel hands down. Thank you for what you do. This is so well done and fascinating
Love every video you make. This will surely be no exception
Thanks Tiktaalik for going out of water. Now I have to work on jobs to pay my taxes until I die.
I have been watching a lot of Eons-videos lately, and this is now my favorite channel on RUclips.
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
These videos will never get old. Fascinating!
My day has just been made
finally! I've been waiting for this one for so long
I love listening to stories about my ancient ancestors 😊🐟🐟
This is a fantastic channel. I've previously been more interested in physics than biology, but the subject's fascinating. Thanks :)
This channel is one of the few things that gives me hope for humanitys future, seeing how few people watch theses on the other makes me lose that hope again
You guys really put the “eon” in Patreon 😂😂 I’ll leave now
thaaank you for all of these amazing videos!!
Love this channel so much
Great video, as always. But you have the evolutionary order (character state polarity) of the lung and swim bladder backwards. Lungs are ancestral, and are widespread in primitive bony fish (like bichirs, bowfins, and dipnoans [so-called "lungfish"]). Tetrapodomorphs inherited the ancestral trait (itself evolved from an outpouching of the gut). The swim bladder is a modified lung, found in the vast majority of bony fish.
This isn’t the first thing they have misinformed people on. This is why RUclips is a bad source of learning. No one to check RUclipsrs when they are wrong and they ignore all these comments cuz of publicity
@@almightyZAW
Can you cite other examples of them being wrong?
Do you have sources for that? That is hard to believe
@@lithobreak3812 ???
You know the real reason people are questioning you and not eons? Because they made information accessible and wanted to share it. You just wanted to prove how smart you are. "So-called lungfish" pfft.
YES! new video :D
can't wait for another one, guys. loved this!
Beautiful presentation
this was amazing!
I really love the prehistoric life. Thanks Eon! 😊😊😊
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

So uh what happened 💀
I have never felt so grateful for my lungs before. It is indeed good to be able to breath air.

Wow, I’m impressed by the atmospheric counts from each age Durated-ratioed.
I love how you mentioned those things of such history grouppreciated.💌
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.
