- Can life be created spontaneously? Well, a year and a half ago, our master of microscopes, James, was inspired by the idea of spontaneous generation and set up his own little experiment.

I know this channel is all about mostly microbes, but could we get an episode about fungi and their microscopic structures?
Yes, more fungi and their networks, please!
More fungi content would be appreciated. They're so cool!
Ah a larger life lover. Nay none of those here. Too big. Lol I'm joking. It would be great to see such things here.
I would love to see fungal spores growing
PLEASE
Hank is the most thoughtful dude, casually making sure the patrons aren't boiled in a flask... Man's watching out for all of 'em.
"These are our patrons on Patrion. If you put them in a flask and boiled it, I would be very mad at you." 😂😂😂
As a cub scout working on a merit badge (LONG ago) I did an earlier version of the experiment involving the spontaneous generation of maggots in rotting meat. I was able to prove that even cheesecloth can be made to smell really bad.
Huzzah for science!
I had a friend who left a sealed container of worms in the back of his car after a fishing trip, for over a week. All the worms transformed into maggots, and the worst smell I have ever encountered.
@@moosemaimer Well in that case it’s alchemy. You’ve just converted one kind of worm to another.
@@moosemaimer Fly eggs are tiny, newly hatched maggots are even smaller, they can fit through the most impossible cracks.
Your comment revived my memory of the incredibly stinking maggot jar I created, while trying to observe them turn into flies... had to abandon the experiment.
This episode reminded me a lot of mycology being that you have to pasteurize and sanitize everything to prevent microbial growth, but not the deprive it of air for the mycelium to grow
You know I have to wonder if life started multiple times. Like civilization. How do we know it’s one common ancestor instead of multiple that just transferred a lot of genes?
These are so chill and informative. Best videos to wind down with
I found something in a moss sample a few weeks ago I couldn't identify, and then from watching this video realized that it was a spore!! I am so glad this channel exists.
Could have been a moss spore since moss are seedless non vascular plants! :)
This is sooo soothing. The music, Hank’s narration. Wonderful.
And interesting, too!
could do a video replicating pasteur's fermentation studies (it's weird to think of a time before our modern understanding of yeast)
this video only explains the "where do maggots come from?!" part, but does not even remotely touch on the main idea in abiogensis being the specific inorganic recipe preceeding life needed for that thing to become life.
idk if intentionally misleading or not, leaving out things such as the Miller-Urey experiment?
while the conclusions of creating amino acids and the possibility of creating life from amino acids is uncertain and inconclusive, it seems very worth mentioning.
especially since at the end of the video, Hank talks about how we in fact "concluded" that life can't come from "nothing.", when literally all they look at in this video is already-existing microbes, not even remotely helping in the case of searching for the origin of microbes.
I know it's dumb, but every time I remember this channel is gonna end I want to cry. These videos are truly special.
since i learnt about the oxygenation event it fascinated me that anaerobic bacteria have survived all these years with such inhospitable conditions, they literally survive under the soil and inside us just waiting for us to die so they get their turn to thrive, weird how a planet can be so inhospitable and yet so full of life. We are the invaders, our ancestors benefited from that event and we have thrived ever since, what could the world be like if that oxygenation event never happened, how advanced could anaerobic life get if it was given as long to evolve with favourable conditions as our ancestors had, if they are the dominant form of life in the universe then it could be anywhere and everywhere across the universe
Somehow I thought this was going to be about the formation of life on the early Earth, about how it might have gotten started, and asking if that same thing, life just starting from amino acids and the like, can still happen today. My guess would be that it is still technically possible, just extremely unlikely since it is a lot easier for life to come from other life, and offspring of already existing organisms would have a huge head start over anything that might generate from the right conditions.
But who knows, there might be microbes on our very planet that aren't at all related to us, perhaps even right under our noses. Imagine how huge that would be to discover.
Sounds like a decent B-horror movie premise
@@Badficwriter Come to think of it, yeah. Or an X-files episode.
Something cannot from nothing. Its a contradiction
@@qureshib61 Nobody is saying that, though.
@@qureshib61specifically by "something" they mean life, and by "nothing" they mean non-life.
this video makes a conclusion i strongly disagree with and i even suspect deceptive intentions with what very important information they decided to leave out!
(specifically a religious bias since fundamental theists are very afraid of the idea of abiogensis since it contradicts the theistic creation story.)
The Fungal spores at 5:26 really remind me of the genus Alternaria. Im incredibly certain that it is at the very least a Dothideomycete from the order Pleosporales.
That is where my limited knowledge ends.
Ill just presume it is an Alternaria species for now.
I have an unusual request, I Want to know what kind of microbes exist in like a lathe machine's oil and surface, how about machines that are sterilized? I'm just curious what sort of microbes exist in the surfaces of non living things, how about gasoline or engine oil? Hydraulic water?
I often wonder what microbes can survive on things like scrap metal and old rubber, and yes, in old oil and fuel and such. I'm just genuinely curious, being around that stuff all day. Would a microbiome like that be considered "artificial"? Have we triggered the evolution of entirely new species by leaving so many metals and petrochemicals exposed to open air?
One of the best channels. It’s like every being is a planet of microbes.
How do the "correct" microbes discoverd and get to their corresponding food source, like how do the bacteria arrive at a carcass or why does mold appear even in a cloes box? You could call it; The dynamics of microbs...
Ok but how did the bugs get in his bottle tho
"These folks here are our Patreon Patrons. If you put them in a flask and boil it, I would be So. Mad At You." XDDDD
Could you make an episode on Frits Zernike who received a Nobel prize seventy years ago for inventing the phase-contrast microscope?
Like vacuum energy and virtual particles? Spinoza is doing the twist in his grave!
"These folks here are our patrons. If you put them in a flack and boil it I would be so mad at you."
😄
I'd be interested to see Viktor Grebennikov's beach sand experiment repeated... His work seemed to support abiogenisis but it's possible there was a source of contamination.
please include whether the footage is brightfield/phase or dic
Hank Green, you sir, are a legend of our lifetime! thank you soo much for your delivery of concepts and science covering an amazing spectrum of subjects. thank you from the heart. my kids have grown up loving science and being curious, largely in part to your youtube videos.
Are there bot only 2 options? Either life/microbes/organismis always existed, or they can spontanously form (as the first one did)
Beautifully told. Thank you.
Can we hear of the updated experiment
This makes me think of a related topic:
If the earth's first microbes were spawned from naturally-occurring chemical mixtures in earth's early history, then why don't we see that happening anymore?
Because there’s already developed microbes that will eat those organic chemicals, so new life is out competed by the life that already exists which use those developing complex molecules to sustain themselves. I find it interesting because when you think about it, it makes sense that the molecules that make up developing life (or similar chemical systems) would be nutritious to already existing life, and so those complex chemicals never have enough time to evolve into more complex systems, which would likely require millions of years unimpeded, which won’t happen anymore with our current environment.
I'll add that this is why they call The progenitor chemicals "primordial soup". It's literally just soup. Sugars, amino acids, oils... you could eat it. Dunno if it would be tasty.
It's entirely possible that there is an entirely unique microscopic biosphere on Earth that generated separately from the one we evolved from. Perhaps multiple. The problem with discovering it is that the world is huge and microbes are extremely small, and would generally be outcompeted for resources by the predominant biosphere (ours). So if it does exist, it's likely carved out a very tiny ecological niche.
@@dolebiscuitEarth probably has only the one tree of life but there may have been more in the early days. We know that from the deepest rocks to the highest mountains to the hottest hydrothermal vents to the hull of the ISS, all life is genetically related and there's pretty much nowhere that life can't be found on our planet. We know some of our bacteria can thrive even on Mars. If there was another lineage or a thousand of them they would have to contend with the competition and several mass extinctions. The great oxygenation event alone would probably have destroyed all of them.
@@dolebiscuitplus, how would we know if we discovered it? Any observation would probably be accidental, extremely remote and immediately contaminated by the more developepd junk we're carrying around with us.
So Pasteur proved that the "spontaneous generation" of organisms is just an old-fashioned wrong idea.
Donde están las tiendas de Microcosmos?
Well done, very informative.
Would be great if you were showing some kind of a schematic or animation of how the experiment setup looked like at 9:00 timestamp - the experiment with S shape tube. I was listening to this but don't fully fully get it yet without googling more. But overall an amazing video, thanks! Please make more videos about history of science, how they managed to build the experimental setups with the knowledge they had at the time, and so on. If you're reading this comment - can you please reply with a list of books you recommend on the history of science, biology, chemistry, physics? Love! 🫡💚✨
I mean, it's easy to turn grain into mice, provided you also have 2 mice 😛
Another idea of things coming into existence is by dusty complex plasma particles as described in the "A new science of heaven" by Robert Temple. An awesome book.
Vive la spontaneous generation!
You need to make an audio book and just talk into depth about this for eight hours.
Hank green voice is so iconic
Abiogenesis is another term for modern origin of life research, which seeks to explain how prebiotic chemistry became biological life.
which they weirdly don't talk about at all in this video
Can you talk about Abiogenesis next?
They'd have to talk about panspermia if they did, because that's the only other explanation that fits the worldview.
@@spamin8r "they'd have to talk about panspermia"
Uh, no they don't.
Also: "worldview"? That's a little weird, to call it a worldview. You're sus.
Dam. Just discovered mine is a ko. I knew it just felt a bit "off" wasn't until i went and looked up how much they were going for on Ebay and saw a suspicious number being sold from China. 😢
I love microbe history videos as well
Thx for the best
Thanks Hank
Cell theory states that all cells come from other cells
had to happen at least once
I'll find it easy to believe that an iPhone can be generated spontaneously but not the simplest cell.
What? That makes no sense.
Spontaneous generation may be disproven, but abiogenesis certainly isn’t.
Makes you wonder how future generations will look back at our current science
I knew this wasn’t going anywhere before I clicked. I took the bait. But I knew it would either say what is know that abiogenesis is impossible (for many reasons not mentioned here) or this video would lead the hopeful listener on.
Abiogenesis isn't impossible, because it very clearly happened.
😂😂😂 unfortunately, mainstream scientist don’t agree with you.
That doesn't look like a very conclusive experiment
They appear when you break wind lol
it was so brave of louis pasteur to stand in front of a crowd in a dress in the 1800's
History quickly forgotten... Antoine Bechamp rolls in his grave.
Even if microbes came from outer space, still they appeared from nowhere somewhere in the universe.
Spontaneous generation
Is Hank the American Simon?
The origins of life theory... Is exactly the same of the spontaneous generation theory 😮
greek philosopher type question
yup everything came from nothing how do you think the universe started?
If spontaneous generation isn't real and can't happen where did the first life on Earth come from?
I would point out that this only disproves EXISTING microorganisms from appearing from nothing, but does nothing to disprove whether microbes could eventually form from non-living substances. Otherwise how do you ever get life in the first place? If what you're saying were true, then life would need a creator, but that's clearly not true. Organic compounds form and then become the building blocks of certain chemicals, which eventually form into living organisms after millions or billions of years.
Your assumption is that spontaneous generation is the product of short-term processes that causes it to occur immediately, rather than long-term processes that take vastly longer periods of time.
Yep. And even if there is a creator that just pushes back the question: did THAT thing just spontaneously emerge? A creator would be more complex and have much lower entropy than a simple life form, so where did thay come from?
@@gregoryfenn1462you can't really expect logic from people pushing creationism ideas
@@gregoryfenn1462 That's a point that for the sake of argument I just chose to ignore, but you're right that it would need to be answered.
@@pablovirusthe universe was absolutely created. The Big Bang theory states everything in our universe came from nothing
Wow! 💚
Betteridge strikes again!
there is a video on YT using a vac chamber and mixtures of gas trying to make life
Small things.
What are you guys talking about from Now Where? The living becomes Life it's that SIMPLE!
Lets think about this put vegetables bugs and bacteria in jar and then boil it until nothing left alive. Take to the sun light and wait forever. The jar has enough organic matter so it makes evolution faster. Based on evolution we might see some organism comes random molecular activity. I think the answer is you wont observe living things in it.
Always so fascinating & well presented🔬🦠💚
The thing is we know spontaneous generation CAN happen otherwise where did life come from? The flaw in these experiments, even Pasteur's is inadequate scale. The odds are certainly infinitesimally small, but non-zero.
Spontaneous generation, as proposed in the 19th century, is false and no one in the field of evolutionary biology today would argue it can happen. Abiogenesis as we understand it is not about a single, odd-defying random ocurrence but the completely logical, probable, and progressive organization of organic compounds to form the first complexes with life-like characteristics (e.g. Stability, replication, etc.).
It does need certain conditions and a very long time-span though. So for all intents and purposes, abiogenesis is irrelevant for us (in terms of medical applications for example)
Let's not conflate Spontaneous Generation and Abiogenesis now, OP.
2:35 Can you please provide more details on the experimental setup? Is the plastic bottle completely sealed off from the outside so that there is no leak/exchange of air inside and outside the bottle? Has the air inside the bottle been sterilized and check by the instrument before putting in the field?
I love old times experiments, so fascinating to see how knowledge evolves alongside science.
Next time someone called established science “just a theory”, ask if they reject germ theory too, and if so, why they ever wash their hands
In the beginning was the Code (DNA) and the Code became flesh!
I'm surprised that you can so reliably attract mice.
The secret is the dirty shirt ;)
All the snake hobbyists will never have to pay for feeders again!
O they arive from the total set of conditions for theme to be able to arive in to the behavieures in existanceas microbes❤
It's one of the glaring ironies that today the religious zealously espouse that life can't just spontaneously come about - Yet not all that long ago it was doctrine. It was a widespread article of faith that God(s) actively brought about the miracle of life on an ongoing basis. And Dogma Inc. adapted to rely on the flocks forgetting such little inconvenient facts. At one point Geese were even believed to be a type of fish. And at other times that fish are a type of fruit.
Yes microbes can appear out of almost nowhere. That is how the first microbes came into existence.
they leave this out in the video even though it's the main point of abiogenesis which they even mentioned.
rejection of abiogenesis is common in fundamental theists since it disagrees with their man written stories, and while i don't want to sound too cynical here, i know that Hank is a Christian, and it would tooootally make sense for him to leave out the main point of abiogensis.
I mean that’s how life started isn’t it
Doubt. We just lack the capability to figure out what's going on.
Howdy
Hey guys- i know its not what you are talking about but it sounds like you are saying the origin of life must have been God because abiogenesis is impossible..
It woulda been better if you'd been clear you were NOT talking about that type of abiogenesis.
They weren't talking about _the_ Abiogenesis, not "that type of Abiogenesis".
No they grow from super tiny particles just like everything else
Exactly. There is always something smaller. And always something bigger.
There is no logical reason to have a limit in sized. Only a limit of what we can observe
What an incredibly misleading video. Implying that there's been no advancement in abiogenesis studies for the last 150 years.
If someone were interested in more recent developments (not implying that abiogenesis has been confirmed - we're a ways from that yet), they might want to look up Nick Lane's lecture at Gresham College. It's available on RUclips titled, "Energy and Matter at the Origin of Life."
I agree with half of the title " energy and matter at the origin of life."
IMO, matter IS energy.
No. Nothing just appears out of nothing. Period.
For life to just appear, you would also have to have all of the genetic information just appear out of nowhere. Which is the equivalent of expecting a book to just appear from nothing.
Lol. I take it you haven't done a shred of research on the topic?
@@nobody.of.importance Actually I've done tons, lol. I love science.
I take it you have gleefully opened wide and swallowed whatever you've been fed by the fundamentally materialist establishment, like a good little non-thinker.
Does it taste good?
@@OYME13 Yeah sure. And you have a million dollar business and your wife's a supermodel. Sure dude. You can't be a lover of science and deny it so openly, so nobody believes you.
The Earths moon was a molten piece of the planet that is now the asteroid belt. The moon hit the earth when it was water covered (earth is at the right distance from sun to collect comet water), and the impact made a huge volcano that cooled into the super continent Nuna which came together and apart to form Rodinia ,which came apart and together to make Pannotia which came apart and together to make Pangea. The impact stirred up our core making our magnetic field stronger, put massive amounts of water vapor in the atmosphere and caused super massive thunderstorms that may have sparked life if we weren't seeded already. The side of the moon that faces us is shaped like a slightly deflated ball and has alloy metals from earth on it.
There were supercontinents before Pangaea, such as Rodinia and Pannotia. It's just the most recent. The collision that created the moon happened over 4 billion years ago. Pangaea formed about 336 million years ago.
@@JCO2002 After looking into it i guess the moon impact volcano must have cooled into the super continent Nuna which came apart and together as Rodinia which came apart and together to Pannotia which finally made Pangea. ...probably a few others in there too. Scientists say they come apart and together about every 600 million years on average but i think the early ones moved faster due to the thinner crust layer. Thanks for your info i don't know it all but i will try to till i expire.
@@JCO2002 im goin to edit my original post
@@eternalspring1034 Cool. Glad to have helped.
Evolution of life.. Nothing comes from nothing. Life didn't always' exist.
There is more to it. Everytime I bring jackfruit to my house, out of nowhere a small type of flies appear in no time. I don't see those flies otherwise. It seems that they appear instantly at that very moment. There is deeper mechanism going behind.
of course life came from non-life
Ehal
Imagine , a self replicating system... I can't actually imagine it happening , but I heard the electron gradient created by deep sea vents became the first life itself , instead of being a self replicating molecule coming together by chance
As long as the scientists' have true passion for their research (that isn't based on personal monetary or career advancement) you're correct. That's how science works best, and should always work. However... as you stated, we're dealing with humans. Greed will always try to find a way. Getting more difficult to find real passion, which makes it more difficult to trust the results they present. I wish it weren't so, but there's rampant corruption afoot in many scientific fields. Shame that the honor system seems to be less effective as time marches on.
It‘s not only monetary gain though. The academic system is currently struggling a lot, since everyone expects high impact publications with ground breaking discoveries every few months. Which is quite impossible.
Unbiased science is also interested in negative results, but they‘re very hard to publish
I feel like it's more a problem with journalism and science reporting than with the science itself.
@@LimeyLassen it really is
@@LimeyLassen
No, unfortunately, it's scientists as well.
What is the definition of LIFE ?
" Non- linear observable movement/action" ?
I think its time to modify the definition of LIFE..
Problem with "James'" bottle experiment out of the gate. Was this a sterilized bottle? Did he handle the bottle with sterile gloves in a sterile field? Anything and everything could have contaminated that bottle and the "experiment" with microbes, fungus, etc. AND if the seal wasn't airtight, all matter of things could get inside the bottle, especially when left outside as in the case of this "experiment." If you're serious about testing the "spontaneous" generation of life you need to be MUCH more meticulous.
Kind of wrecked the rest of the video for me because of such a cavalier manner of testing the theory.
Mendel
How about the arrival by Asteroids?
So does that mean that life on earth did not spontanesly generate through bajillions of possible combination in the primordial ocean but rather thru travel drom a foreign meteor or comet?
If you made just the right mixture, exposed it to just the right amount of heat and light and electricity, and gave it several billion years, then it is assumed life WOULD eventually come to be.
I mean, even if it did come from a meteor or comet or something, that just moves the question from our planet to another one. How did that life start?
It's wild to think that we haven't actually answered the question of abiogenesis. We just... moved it back billions of years and changed out "spontaneous" with "needs the exact right circumstances that make it even just a teeny bit possible and enough time to turn a one-in-a-billion chance into a 'it'll happen eventually' probability."
Theres an Rna cloud in space. Maybe we live inside a giant. Hope we're in the memory part of the brain.
to make the comparison of oysters coming from sand is by far the worst explaination of abiogenesis i have ever heard in my entire life. i apologize for harsh words but come on.. 😭
