I never knew about such kind of lakes or the fact that oxygen was once a 'poisonous gas' that caused so much extinction. It's all so fascinating. The lake seems like a time capsule that we can look intoto know about ancient origins and evolution of life on earth.

@@simranmalhotra7364 Do you think humans are some alien species from another planet? We're also a part of Nature. As far as we know, we're the only part of Nature that has self-awareness and can consciously effect change in the environment. The only real issue is how we use our intelligence. My point is that if we were ONLY a part of Nature, then we wouldn't even give thought to the harm we do. We would just eat and grow to the maximum extent possible, like all OTHER living creatures. The bear doesn't worry that moose are endangered if it has a moose in its sights. Mass extinctions happened long before humans ever came along.
I've been researching this for some time!! As a follow up to this you should do a video on the horrors of limnic eruptions (can only occur in meromictic lakes). I can't believe I'm just learning about them. They could be the irrational fear replacement for the next generation and overthrow quicksand and sharks!
Just wait until you hear about the carbon cycle in the oceans. TLDR, CO2 enters the water towards the north, travels all across the world and is eventually released again, a few thousand years later. Now if we think about what has been happening since industrialisation.....
@Jdog1681 I went looking and it's not Ted, it was SciShow. Sorry. If you still want to watch it, it's called "Limnic Eruptions: When Lakes Explode". Again, sorry, my bad
Look up "Green Lakes State Park" in New York, near Rochester. It's just outside Rochester. It's also a meromictic lake. The water is crystal bluish green
"All life comes from a single moment of creation. Some 3.8 billion years ago in some bubbling mud pot or deep ocean thermal vent. Some little bag of chemicals twitched and became animate and than miraculously reproduced itself. Everything that lives now on earth, or ever has lived, descends from that moment. We are all built from a single original blueprint. I don't believe there is a more important or remarkable fact in the natural world, indeed in any world, then that one." ~Bill Bryson
Creatures with any mass whatsoever are forced to see time as a linear progression. There's a past, present and future, with no crossover between the three, because we are constrained by the speed of light and must remain inside our light cone on the time line.

Great video, thanks for that. And it is kind of mindblowing, that all accesable iron on this planet, is a result of the great oxidasion event. Iron used to be suspended in seawater, but when oxygen apeared, it turned to rust, and sank to the bottom, where it became part of the rockbuilding proces. So now we can dig it up, and use it to our hearts content.
Those oceanic vents are probably the best clue for the beginnings of life on Earth. But it's very hard to study and extremely hard to replicate those Archean conditions, because the whole planet was sulfur-based, as was all life.
What if in other worlds, the great oxidation period did not happen and these anaerobic organism flourished. It's fascinating to know living organisms not needing oxygen.
3:53, shouldn't that be carbon dioxide as opposed to oxygen? always love these vids, informative, interesting, and somethign about the way they're set / spoke is just relaxing!
Well, no. Plants and Algae (an artificial group) rely on oxygen to realize the oxidative phosphorylation, just as in us oxygen is the final-acceptor of electrons of the electron transport chain, responsible for generating the major part of the ATP molecules used as energy source in our organisms. But plants perform phytosynthesis as well, fixing carbon dioxide to produce complex molecules and oxygen.
All I could think of was, fishing Lake Cadagno: bucket list. Switzerland or bust. I mean, when I hear Swiss, I think, chocolate, cheese, opening a formidable account, the concept of armed citizenry with super low firearm deaths-injuries, nifty flag, natural beauty, natural beauties, good everything, averages on high ends... But, great fishing, and tasty, organically healthy all the way catches? I suppose, naturally. Of course. Just never equated Switzerland to indelible memories of sport fishing love, before this video.

353 Should correctly say that the purple sulfur bacteria rely on H2S like most plants rely on H2O. S2 and O2 are waste productucts of the respective photosynthetic processes.
I think I disagree with the premise. The lake is only thousands, not millions of years old. This means the creatures that live w/o oxygen have developed in response to this unique environment. It has nothing to do with conditions existing over a billion years ago - except as a testament to the resiliency of life.
A new book published by Austin Macauley Publishers titled From Chemistry to Life on Earth outlines abiogenesis in great detail with a solution to the evolution of the genetic code and the ribosome as well as the cell in general using 290 references, 50 illustrations and several information tables with a proposed molecular natural selection formula with a worked example for ATP. It proposes that the Earth was subject to many minor oxygenation events involving manganates splitting water or hydrogen peroxide as well as the breakdown of titanium oxide with UV light catalyst.

Crawford Lake Ontario Canada is also a meromictic lake. Somewhere on the bottom, my Dad's sunglasses lay preserved forever.
That sunglasses would be broken down by bacteria by now😂
@kentas1087 If there's no oxygen and they were made of metal then they won't rust. Why would bacteria break down a pair of sunnies?
It's like a natural time capsule!

@@IMasterSkeptic That's a very condescending attitude.
It's not oxidation as it means like rusting of a metal due to oxidized iron. Its correct term is "oxygenation".

I never understood why we assume that alien organisms would breathe air and need water.
Exactly my thoughts.
They might breathe water and need air.
Theoretically speaking, all living things need water in order to survive!
They might be also carbon life forms
They may not, but our best first step is to look for planets enough like our own to support life as we know it

Good old sp2 orbitals on the carbon if I remember.
Wait, so what gas was before oxygen?
Nitrogen, CO2 etc
@@BeninArmyLeader ah thank you 😊
@@paigewhitfield3624 Nitrogen still takes up most of the air but the amount CO2 had been greatly reduced because of all the photosynthesis..

Fantastic information in a brief, understandable video
So amazing, thank you.
Top notch animation quality with great explanation
Thanks.. it was magical to watch
I too, am obsessed with this lake
What a delicately preserved environment!! I wonder if humans ever will have such an area if something bad happens.
Life is amazing, in all it's forms.
1:45 Damn, imagine being a freediver not knowing about the sulfur layer until it's too late!
Doesn't really matter if you breath water or some sulfuric solution.

I love the animations in this video.
I have seen stromatolites at the bottom end of Shark Bay WA AU. Still producing oxygen millions of years later.
Very fascinating food chain starting from the depth
Excellent video. Would like to see a photo of the purple bacterial layer.

The lakes in the Vestfold hills (Antarctica) have a similar ecology.
Congratulations Ted! Your gonna reach 20M subs 🎉🎉
04:40 whoever thought it was a good idea to have the diver show up to the lab with the sample still in full diving gear is a comic genius 😆
this only raises the question of what’s the chemical formula for that water with no oxygen? is it still H2O? just H2?
It is H20 oxygen talked about here is oxygen dissolved in water like in atmosphere
Question: how did the fish get there. Like caldrons here in America, where fish seem to thrive, even though, there is no water system feeding it.
Fish eggs have evolved to stick birds or survive their digestive system.

@@I_have_no_username *but also requires oxygen. They just produce more than they need

I'm very interested in creating an artificial model. Wouldn't it be beneficial to do this to more lakes to improve ecosystems?
Lake Baikal in Russia is huge, deep, and old. I wonder if it's meromictic, a term I've never heard before.

With so many large fish, how does the bottom not fill up with mulm?
Why doesn't the salt diffuse into the top layer?
Salty water is heavier than freshwater. Kinda like how brine pools remain intact coz they're saltier than the surrounding seawater.
This would also explain why the brimy river in Subnautica is even poisonous to the players if they try to swim thru it.
Totally unrelated but you guys should do a video on the Mau Mau Revolution (in Kenya, fighting for independence & more)
Why??
To think oxygen was once deadly
It seems as if without oxygen an organism can never become too complex. Is that true?
