- Hydrothermal vents are some of the most extreme environments on the planet. But in 2000, scientists discovered a vent unlike any other, one that spews white smoke and is 10 times older. And some think it may help us understand how all life began.

Again I want to thank the entire SciShow team for being here for us all in trying times.
Melodee Aaron ah yes, I also needed a Subaru ad disguised as a video
It's a nice touch of normalcy; thanks, guys!!
Excellent delivery. Great voice and actually conveying info rather than reading. Great stuff.
We got plenty of olivine here in Hawaii. One of our beaches is “green” from all the olivine in the lava rocks. ImuaTMT
Man, this one wins the "Most Complex SciShow Episode" award, I had to watch this four times to wrap my mind around it.
"Dang it, Jim! I'm a doctor, not a geo-bio-astro-chemist!"
Did you find out why they published this video now? The science they present is from 10-20 years ago, or did I miss something?
Thanks ... I get to a point where Michael goes (again) but that's not the most interesting part .. and I think - wait, what?
@@eljanrimsa5843 I didn't read it 20 years ago, so I'm very happy they published it now. Truth be told, this is a 'history' primer, so everything I read about it from now on will have a good grounding. *facepalm*
@@eljanrimsa5843: This isn't a news channel. This series is even called "Weird Places".
I love watching Michael Aranda. I miss his blonde streak. The science was awesome too.
I've noticed he's doing less of these videos! Come back man, you're a great presenter!!
I agree 100%!
Indiana Jones: The Lost City and the Origin of Life
White smokers, sounds like my school
A school of; Crack commando's?
Four twenty!
I'm reading Nick Lane's "The Vital Question" and this helped me to visualize and recap some of the processes he talks about. Thanks so much!
Sci Show does always an exceptional work!!!!!Feedback:When you explain chemical reactions i,i think it would be better to show graphs,and pictures.It's much easier for the brain.!THANK YOU.And please upload more interesting stuff about the origin of life,Astrobiology,Extremophyes and stuff like that
I'm do happy that i am alive sci show is the best
This went way over my head, but still cool and interesting
Well, of course, it IS at the bottom of the sea. Over everyone's head, that.
Methane is also a fuel that releases much less carbon dioxide than other hydrocarbons. This is because it has the lowest Carbon:Hydrogen ratio possible without being completely hydrogen.
lol blow it out ur ass!!!!
🐿💨💨💨👈🐿😂
Just watched the cosmos episode on this topic! really neat!
Seems like it would be relatively easy to find possible life on Io, the place is like one gigantic Yellowstone Park. It's got hot places, cold places, warm places, all sorts of organic chemistry in liquid.
Agreed! I think it's amazing what Sci-show is doing. They have inspired me to start my own channel on sci-fi topics, including why asteroid mining may enrich humanity!
@SuperStarWhale Why is that?
And he means it. Point. Blank. Peridot.
I'll see my way out.
Keep your day job, if you still have it. :)
I like learning. Great video, Keep up the good work. God bless.
Happy Good Friday.
Yay Michael Aranda is back!!
Great ep!
That's quite interesting. Olivine is also found in many meteorites, the most well known of which is Pallasite (absolutely beautiful when sliced and polished btw). This is even more remarkable because of two facts:
1) Water arrived on earth FROM meteorites (not comets btw).
2) Hydrocarbons are commonly found in meteorites as well
While some meteorites come from smaller bodies, many are known to have come from larger, more developed planetesimals that eventually broke up/collided with another body and were destroyed. Now that we've actually observed this process, it doesn't seem like a stretch to say that the Hydrocarbons found in those meteorites could have come from similar reactions on other bodies, just at a much smaller scale.
And no I'm not suggesting life arrive on earth from another planetary body. Merely that the same process of abiogenesis that occurred here on Earth, can apparently also occur elsewhere in our solar system.
If it can here why should it not elsewhere
CORRECTION: The mantle is not molten. It convexes but remains in a solid state as the (solid) olovine behaves much like a liquid over large time frames and with the vibrations of eons of seismic activity. We see similar behavior in ices on Pluto and Europa -- those "cracks" are largely believed to be zones where the colder material is subsiding.
EDIT: I think it's possible that much deeper portions of the mantle can become molten, but not anywhere near the crust.
Thank you! I have been trying to tell people that there is one case where water does go above 100C without turning to steam.
This is an incredibly exciting area of research right now (Lost City), and it may give scientists clues for what exactly to look when searching for life on other planets. A wonderful book on the cutting edge of this research is, "The Vital Question - Energy, Evolution, and the Origins of Complex Life", by Dr. Nick Lane, a biochemist who leads the University College London Origins of Life Program. Dr. Lane is an eloquent, passionate, and brilliant writer. I highly recommend his book, (he has written several other fantastic books as well). His closing words: "Rock, water, and carbon dioxide - the shopping list for life", and, "May the proton-motive force be with you". (ISBN: 978-0-393-08881-6)
Thanks, I'll definitely check it out!
Holy crap, it pours out hydrocarbons?
We could everything from that, that would be an excellent place fire life to evolve.
Delicious electron gradients!
"delicious electron gradients"
I tried them 1/10 would not recommend.
wow. lots to process. i'm gonna have to watch this again to get a grip on all of that science that just got dumped :)
Finally! Vespine gas vents!
Thank You this vid was so helpful!!! Save me for my oceanography class lol!!
Serpentisation, olivine. Did you get the idea of this episode from cosmos possible worlds?
Great now I can't help but imagine being able to faintly hear "CLODS!" being yelled in a nassaly voice around those vents.
Haha, agreed! Anyway, I think it's amazing what Sci-show is doing. They have inspired me to start my own channel on sci-fi topics, including why asteroid mining may enrich humanity!
Where's Lapis?
@@KellyClowers fused away into Serpentinite, d'uh
I’m like Michael’s voice. He’s my favorite SciShow host.
Inspirational! Microscopic things start growing in the water, get energy mostly from the starlight and disintegrate through a chain of complex biochemical interactions to become a part of the new life cycle. (Correct me, if I'm wrong.)
Agreed! I think it's amazing what Sci-show is doing. They have inspired me to start my own channel on sci-fi topics, including why asteroid mining may enrich humanity!
@Dixie Ten Broeck That's a bit crazy, I know. My sincere intention is to formulate a simple view of the inevitabile appearance of life and point on the beauty of our nature, especially of those delicate structures underwater.
Great content! Would be great to see a follow up video on geologist Mike Russel's work on predicting the existence of white smokers before their discovery
*white smokers*
Well of course I know him, it's me!!
Black smokers you say? well, that would be me and my Newports!
*insert clever Left4Dead reference here*
@@WintrBorn Ok Boomer
Nyan Kitty witch, please.
This is a bit different from what I learned prior that white smokers are black smokers which have moved too far from the tectonic boundary to get compounds from the mantle. Thanks for sharing, SciShow.
Wowzers!
This was so cool. I love how things like the story of Atlantis keep influencing things in science. It shows how connected disciples can be.
The way he says peridot.
Thats my birth stone and just don't sound right there's a DOT at the end 😂😂
Interesting new pronunciation
Walk into a jewelry store. Point at something with a lime yellow greenish stone and ask what it is called. 95% of the time the jeweler will say "Pear ee doh"
Go to Phoenix, drive an hour east to the town and ancient volcano that has a lot of it and ask "What's the name of this town again?" and the locals will say "Pear ih dot".
Great video. Although there are a couple images in the video, he should replace some of the clips of him talking or the clips of words on a screen with visual representations of what he is talking about, like illustrational video clips or otherwise. I'm having a hard time conceptualizing what the chemical reactions are doing using just his words and no visual. Irregardless, he explained everything so plainly that it was still very easy to understand! I just had to keep pausing and re-watching haha. Thank you for posting this. It is helping me a lot with a science report I'm doing on the Lost City.
Cool science shows have always been my jam brah
Cool science/hot vents
I learned about black smokers from SeaQuest DSV beck when I was a teen. Loved that show.
The thumbnail asks, "What is a white smoker?" My immediate thought, 'the beginning of a bad joke."
Schmidt Ocean Institute has a research vessel there now, exploring the area. They live stream some of the ROV missions.
Awesome as ever and thanks for always being there! ❤️
Atlantis? Lost City? Man this could almost have been an April Fools video! 🤪🤣☮️❤️🌈
Michael, where did you find your Birds Aren't Real shirt? I really like that one.
birdsarentreal.com and Amazon have them!
Couldn't focus ... That majestic goatee .
Did they explain why it's called "Lost City" and I missed it? The science is fascinating but I kept wondering about the name.
Yes. This thing is in the Atlantis massif, which is in the Atlantic Ocean. That made somebody think of The Lost City of Atlantis. There you have it.
The process built tall underwater towers out of bicarbonate and so on.
@@jmchez "That made somebody think of The Lost City of Atlantis."
I wonder how many people upon hearing what the scientists call the feature use it as evidence of ancient civilizations. I'm guessing it's not zero.
Just a nitpick, but at 5:18 Europa and Enceladus are actually mislabeled; the picture on the right shows Enceladus, which is much more heavily cratered, while the picture on the bottom shows Europa, which has almost no cratering and a much more 'dirty' appearance due to the presence of salts.
I love the ocean so much, i can't wait to explore it *when this DAMN pandemic is over!*
I remember to have wathed one of the recent episodes of Cosmos in which they mention that olivine is one element necesary for the origin of life, this video confirms this affirmation.
Lost City? Just equip a Dramen Staff, and enter the shack in the swamp. Duuh.
Zenyl the hard part is getting the staff.
I think the most promising theory for where life arose on this planet currently is the nuclear geyser theory, this ticks more boxes than the others including deep sea vents. Would love a video from you guys at sci show giving us your thoughts on it
Ngl, some parts of this made me want to burst out a vessel over hoe complicated it sounds. Its still a lot fun tho lol.
Cool
did he just pronounce peridot "peridoh"
If it is a French word that is the correct pronunciation.
Jewelers say pear ee doh. The Arizona town from which they were first mined is pronounced pear ih dot. Your choice.
When life first appeared on earth ultramafic rocks rich in olivine were much more common than today, which corroborates the hypothesis
The way he pronounced "olivine" and "peridot" is certainly something I have never heard before.
Agreed! Anyway, I think it's amazing what Sci-show is doing. They have inspired me to start my own channel on sci-fi topics, including why asteroid mining may enrich humanity!
As far as I know that was the correct pronounciation of Olivine, and Peridot can be pronounced either like he did or more like it's written. Either'd be correct.
I've always heard them pronounced olive-eye-n and pear-ih-dot
Life is Strange indeed
I knew about these because of a project in a programming class I made in eighth grade (2010)
Lost City of Atlantis Massif. Yes, a totally random name, haha.
How do people just find stuff?? And like not be doing the macarena for the whole month..?
Cause I do that when I find a $5 note in my jeans.
And that's not even something new..
LOL So true.
Who says they don't? ;)
**reads the title**
sounds like my dad
I cant stop looking at the hand movements.
There are lot of theories for Origin of life but ultimately they come down to combination of Hydrocarbons. We are not very sure about exact set of past events.
Anyone good with YT settings? I used to see videos on right side but they dont show anymore, anyone know what i do to see them again?
Wow really
This was on Cosmos the other day
Yep, I watched that too ^_^
hydrothermal vents: I can be your angle... or yuor devil
Lol this is so funny- just got done talking about deep sea life and hydrothermal vents in marine biology. Just got done talking about the origin of life at white smokers in evolution.
So you mean Atlantis isn't real??
Not only is Atlantis not real, it's been known to be fictional since the beginning. The place was invented by Plato for use in a set of allegorical stories, of which _Timaeus_ and the unfinished _Critias_ still survive. The idea that Atlantis was ever real is something that crept into existence because the credulous would rather believe an interesting lie than a boring truth.
@@Just_A_Dude In fact, in the three Platonic Texts, he EXPLICITLY mentions Atlantis is just a thought exercise. But then some weirdo on the History Channel was like "But what if he only said that because the Athenian government made him?"
it's kind of real, just not how we imagined
Black smoker! I know one of those.
q. what is a white smoker?
a. my older brother
Bah white smokers... I've always preferred to smoke green.
I'm surprised we haven't recreated life in a lab yet.
They've tried, but every time they fail, namely the Miller-Urey Experiment, and others like it. Still an immensely interesting experiment.
If you mean creating life from simple chemicals then a team of scientists did this a few years back.
@@wesleyson21 I didn't know this, where could I find more information?
Vaga 42 scientists have made “living” robots recently.
I haven’t found any research indicating they have. Any source would be great. This is interesting news.
All of the rare conditions needed to create early life makes me think that 1 planetary body per galaxy birthing life is overly optimistic by a few factors of 10.
Which makes me more scared of death and at the same time more appreciative of what time I have.
The fact that he proposed three moons as places where life could exist, when multiple star systems have been proven to contain planets in habitable regions, but those moons are outside the "habitable" zone, tells me our definition of "habitable" needs some serious consideration.
This video tells me life may be more common than you think.
@@WaterspoutsOfTheDeep your first sentence indicates you did not watch this video.
@@WaterspoutsOfTheDeep you made a public comment. asserting that nature didn't give rise to life. i'm going to refute that. whats more, our right to speak also gives us the right to disagree. i see more evidence that life arose naturally than evidence that life arose supernaturally. this video offers more proof of a naturalistic origin to life.
@@WaterspoutsOfTheDeep there is no difference between macro and micro evolution. they are the same thing. we have OBSERVED speciation events. look up e.coli citrate evolution.
www.evo-ed.com/Pages/Ecoli/index.html
"The nutrient broth .... contains a large amount of citrate, which is included to help the bacteria take up the iron they need to grow. This citrate could be a second food source for the bacteria, but one of the defining characteristics of E. coli as a species is its inability to grow on citrate when oxygen is present. However, after ~31,000 bacterial generations, one of the populations evolved the capacity to do just that. The evolution of this trait, called Cit+, is exceptionally rare. Indeed, spontaneous evolution of a Cit+ E. coli was reported only once in the entire 20th century!"
this is evolution. this is proof that it happens.
but this video is more focused on abiogenesis, an entirely different field of study from evolution. as different from evolution as cosmology is from evolution.
but if you are a science denying young earth creationist, you will have recieved the brainwashing misinformation that everything you dont accept is just a different "kind" of evolution. and that by attacking only evolution, you can somehow disprove ALL science.
but you STILL wont have proven god.
Did anyone else think of Peridot from Steven Universe?
The book "Life Ascending" by Nick Lane, 2009, has a truly excellent chapter on how life probably first appeared on white smokers.
From what I remember from my bio-chemistry class in college many years ago, each step of the process seems reasonable and almost inevitable. Personally I'm convinced that life on Earth was a product of these chemical reactions in cavities on the walls of white smokers. The only thing I would add is that these white smokers didn't have to be in the deep ocean. Four billion years ago the whole earth was volcanic, the Earth's crust was probably thinner than today so that the Earth's mantle was probably closer to the surface. As a result white smokers were probably more common then. There might have been white smokers in shallow lakes or ponds on embryonic continents or on volcanic islands. And there could have been white smokers in shallow oceanic bays or inlets.
It would have been easier to concentrate organic molecules in a shallow lake or pond than in the ocean. I suspect life began in one of these shallow lakes or ponds or oceanic inlets in a white smoker on the surface.
so wait, are these structures made out of a mixture of serpentinite (-/+ magnezite) or just calcium carbonate?
Atlantis? Well SpongeBob discovered that city before humanity
What do you think about a self-reliant personalised system?
Yaaaayyyyyy
I always thought a White Smoker was just an unhealthy ice zombie from north of the wall.
great video ! a little feedback though : maybe ease out on sentences ( visually ) while describing complex chemical reactions - narration in the back ground and wordy sentences on screen at the same time makes it a tad difficult to follow the science
Did you realize you posted this comment at least three times?
@@LuinTathren I did not .. some glitch with my network . Thanks though
How many times has life been created? Is it still being created? Or, was it a lucky one time event?
I learnt at uni that these vents create chemicals that are like cell walls
White Smokers?..Sounds like ALL my old cars.
So... can life emerge again from these vents? Like from chemical compounds to simple like cell things?
That’s interesting. If it can happen before, what would stop it from occurring now.
Not likely; the water is already full of current life, feeding off the materials they produce. Current life is better evolved, more robust and more numerous. Anything approaching a second genesis will likely be consumed in short order.
Pale Guy Smoking a Spliff? Xxx
Nick Lane just entered the chat.
I came to the comments for one reason...
I was not disappointed 😂
"what is a white smoker?" my dad
It really frustrates me that i probably wont be around when all of these mysteries are solved
Agreed- it's a real shame! Anyway, I think it's amazing what Sci-show is doing. They have inspired me to start my own channel on sci-fi topics, including why asteroid mining may enrich humanity!
Just try to appreciate the mysteries that have been solved before and will be solved during your life :)
Annnddd thats a plus that i aint even in my teens yet
W.D Gaster you’re not supposed to be on adult youtube. This is why we can’t have nice things.
@@OrangeFluffyCat my genius is growing everyday bruh
The detailed chemical mechanism is only confusing and distracting (and arguably incorrect or incomplete). It would suffice to say that water + carbon dioxide gets turned into (bi)cabonate + methane + hydrogen, and the (bi)carbonate makes the water alkaline.
Maybe we'll find a plastic bag there soon like in the Mariana Trench
Michael almost turned into vsauce at the end there
Whoa wait, life might NOT have started in the sea? What theory is THAT?
I had an uncle kinda albino lookin’. He was known in the neighborhood as the white smoker.
not enough !! but good :)
- sees thumbnail
- doesnt see people i know
- confusion
Who else was somewhat disappointed that this episode wasn't about some new exciting proof that Atlantis might have been real?
Atlantis was made up out of whole cloth by plato, it's not real, get over it
I wonder if there is any of these events on Titan ?????
Fundamentally life is just chemistry.
@@WaterspoutsOfTheDeep RNA, proteins, amino acids. None of these are "alive." They are all chemistry. DNA is only 4 amino acids in two pairings, small strings of which code for proteins.
