If my ancestors figured out how to crawl onto land, I can crawl out of bed today

I would like to go back in time and see how everything came to be up to this point. Cause I’m sure life at the beginning will be a sight to see

"Many were increasingly of the opinion that they'd all made a big mistake coming down from the trees in the first place, and some said that even the trees had been a bad move, and that no-one should ever have left the oceans." -Douglas Adams, Hitchhiker's guide to the Galaxy.

There are fishes "learning" to live on land right now. Mudskippers, giant mudfishes... There are about 30 families of fishes able to survive on the surface. Some of them for a few hours, some for days or weeks.

I read in a book recently that the main reason life came onto land from water was the evolution of a new and dangerous predator known as the shark.

I heard the music from Outer Worlds. I thought I accidentally had that game running in the background. :p

This is fascinating for a relax Sunday

Saving this to my favorite for my son, grand child and great grand child.

I like how this guy has the outer worlds title theme playing I’m liking this guy already

This is the first time I viewed a Kosmo video. I must say that it a fine surprise. There a few good documentary channels on KZfaq. Kosmo seems to be one of them. I have subscribed and I look forward to discover the rest of the channel content. Thanks for all the work you have put in.

Thank you for adding the chart on the left side of the screen. Thank you presenting the theory as to the cause of the other mass extinctions: evidence of the other impact craters.

We will evolve into the aliens that we so long to encounter

Awesome video, as always! 👍👍👍

Yet the guys who kept knocking on my door keep insisting we came from dust and rib..

Not only do aquatic organisms evolve into land organisms, our Lifeform Material is designed so that plants evolve into simple animals, who gradually become more complex. That's because some planets don't have oceanic gas layers.

Another awesome video!

*Kosmo and The Exoplanets Channel are my favorite channels!!*

Superbly conceived and beautifully executed! Super thumbs up.... and my subscription.

You said out loud that up to 50% of species vanished in the Silurian extinction, and in the graphic on screen that up to 50% of living creatures died out. (9:16) That's very much not the same thing! Many, many individual living things die in a mass extinction even from species which go on to survive, because in order to survive as a species you don't need your whole population... only enough to successfully breed again. For example, in the K-PG extinction, about 75% of *species* went extinct, but about 99.9999% of *individual organisms* died. The species that survived did so with very few surviving members, who then managed to breed a new population again. (Because I know somebody will mention this: technically, of course, both your statements are correct because of the 'up to', in that if 15% of species went extinct and 49.9999% of living organisms died, both are "up to 50%." But that's not really the way the phrases are used, so it's at least hard to understand correctly, even if not officially inaccurate.)

Wait, this all happened 6,000 years ago? Just f*cking with everybody. Great video.

We went from arguing over food in caves to arguing over Jake Paul’s boxing ability with strangers on social media 🤦‍♂️

A crucial step in the evolution of life on land was seed producing plants. Before that terrestrial plants reproduced via using spores or by budding which required them to be near water. The first seed producing plants would’ve had a huge advantage over these other plants as seeds contained their own nutrient and water supply which means they no longer needed to be near bodies of water to grow efficiently. Also consider that at the time most of dry land was still a barren expanse of rock,sand and dirt. So in these conditions seed bearing plants would have gone pretty much unopposed as they spread to dryer habitats. This would also allow various other terrestrial organisms like the various terrestrial arthropods,primitive land mollusks,worms and such to also spread further in land.

😀 Hooray it's Kosmo day!

awesom vid definitely gonna subscribe👍👌

Great video as always

Excellent, well grounded documentary

Great and very interesting video. Thanks a lot for this video...

Great job kosmo

Fantastic work! Amazing🤙

Superb, thank you 👍🏻👍🏻

Very interesting content . Thank you

If y’all start making videos on ancient Egyptian, then I’ll know y’all are reading my mind.

such a great work

Great show

This is why I got to go to work tomorrow, why didn't they just stay in the water?

Wonderful work thank you

whenever do we say water we always think of the ocean, life could have begun on fresh water

Pure poppycock. Thinly sliced bologna between two pieces of fluffy white snow.

Great video. Congrats

Excelente canal. 🎷

I like how he used the outer worlds main theme

This is going to be another million views video, Great work.

The real question is : How did life come into the Sea?

That silurian basilosaurus was cool.

Very well put. Good writing. IMO the videos can me more relevant and cohesive. Or else it can take viewers attention away from the main narrative. ✌🏼👍🙌

How life left the water and came onto land is not an easy question to answer. I was very young when I did that and I just don’t remember. I know I was pre-school age but that’s all.

Life will always try to find any nook or cranny to try to exist in , it's like energy has found another way to change form . 2nd law of thermodynamics .

My husband gave me the link to this video. Not my usual cup of tea but this video was extremely interesting!!!

Wow what a documentary you have produced. Loved the information you shared with us but it should have been more elaborative ..... 3 to 4 parts of 1 hour each. On the subject EVOLUTION OF LIFE FROM SEA TO LAND. Looking forward for the same.

Amazing video

Literally: "It's Free Real Estate"

My ancestors would not like me, I’m a horrible swimmer. My great great whale fathers would be ashamed

You are the best !!!!

Elon Musk might be the reincarnation of that first fat fish with muscles, which stepped onto the land 🏝 🐟

Very nice vid, although I would like to know more about how sealife evolved into insects. The fish into reptile part I find logical, but I can't see yet how fish or even lower life forms would be able to transform into spiders and bugs. Maybe devote another vid to that?

Very enjoyable video mate, really interesting

Good job😊😊

Excellent

excelente!

Best video on evolution thus far in my opinion !

did enjoy Thanks for

Great stuff, and is that some Metro OST I hear?

Tungsenia in the thumbnail is from Life on earth evolution idle game

Religion: Naaaah. A boat, they were all on a boat.

Brilliant

check out Joni & Pete's video "how life evolved to land" for a much better & accurate explanation

The Hallucigenia depicted in the animation is upside down.

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.

2:42 It's the founding titan!

Excellent video, i love ur work. Can someone tell me what's the music around 13:00 plz ?

Thank you.

Here's my theory. We know that the moon is slowly moving away from the Earth. This means that millions of years ago, when the first land animals began evolving, it would have been much closer, and its effects on the Earth, specifically its effects on the tides, would have been much stronger. So animals unfortunate enough to be living in tidal zones could suddenly find themselves miles inland with little to no warning. From there, natural selection did what natural selection does. Animals that could survive for extended periods out of the water had a much better chance of survival. This probably gave rise to the very first mudskippers and semi-terestrial crustaceans who, in turn, gave rise to the very first amphibians and insects, respectively.

This music is from the game outter worlds

What if Life started on Land then went into water to evolved into what it is today. Maybe for safety from predators or for food ... Maybe life was on water & land. Some animal got out of water , some left land to go on water..

Wouldn't life itself be on the surface of the planet? You know plantation to bacteria, great video as always though! 😎

Ovo ce sigorno biti bravo

Evolution at its finest!

Life is Beautiful

Land: Go back to the water fish! Land: Build the wall, build the wall! Land: Who's gonna pay for it? The ocean!

To imagine the complexity of a human being originating from this is ridiculous to me

Wait the music is Dawn of Hope from metro exodus, I wasn't expecting to hear video game music lol

If my ancestors become avian dinosaurs i would never listen to my parents and teachers

If this theory is correct there should be new animals coming on land from the sea even if rarely or some animals in a transition phase between sea and land.

Bacteria somewhere in the late Proterozic, plants (and probably protists) in the early Silurian, arthoropods later in the Silurian and vertebrates in the middle Devonian.

2:27 I pronounce Ediacaren "ED-EYE-AH-SAR-AN" But I dunno if that's the proper way to say it.

Kris is studying for Harvard she can’t hang out tonight

What is the meaning of life?

That damn fish screwed us all

I, as a human, experienced being wet. It was gay.

Sealacanthe was in my text book as this creature but its also in the south sea today no changes in over 90 million years .lol

Aliens kicked us out of the sea.

Attack on titan was correct about how Ymir started she fell in the water and one of those long things crawling are the things that holds the spinal fluids 😨

That's Stargate SG-1 music

Is it possible, that there was no land above sea level, before land life emerged? Could it have taken life so long to move onto land, because there was none yet?

THIS is what our children need to be taught instead of the bullshit religious teachings that unfortunately still pervades...if all mankind fully understands that SCIENCE can explain where we come from and not some ridiculous dogma or book, then perhaps we can, someday, fully realize that there really is NO SPIRITUAL DEITY at all and that what we've been uselessly fighting about for thousands of years has been for naught and that we can and NEED to come together as a human race to realize that we are, in fact, all equal. I'm no major intellect but I've been perennially perplexed as to why otherwise smart people cannot see this???

See "Signature in the Cell."

9:57 what the f**k is Basilosaurus doing in Silurian period?!?!?!?

Mudskipper like fish evolved into amphibians.

Outer Worlds music. Cool.
