We’ve had the idea that life began in the oceans since the 1920s, when it was first put forward. This was cemented in our minds in the 1950s by the classic Miller-Urey experiment from which scientists hypothesized that the ocean-atmospheric cycle of early earth could have been the perfect conditions to instigate life ... but there were many unanswered questions.
Since then, biogenesis researchers-those are the folks who study how life began-have been kind of obsessed with finding that key catalyst that would have brought chemical components together for the first time. And research from the past several years has shown that in some situations, that special sauce could have been UV radiation. And while some teams HAVE been able to recreate the building blocks of life with UV light, no one has yet been able to successfully perform these transformations in experiments that replicate seawater. Meaning that our whole ‘life crawls onto land from the oceans’ idea….could be wrong?
And here’s another problem: while water is a definite requirement for life on earth ...the chemical properties of straight up H2O actually break down proteins. Including things that are made of protein-nucleic acids like DNA and RNA, the genetic material that hold the blueprint for all living things. These days, living cells tightly control their water balance to protect their insides from water degradation, but...how are proteins supposed to have formed IN a substance that actively attacks and degrades them? Scientists now call this ‘the water paradox’.

We’ve been wrong about the origins of life for 90 years
qz.com/761430/weve-been-wrong...
A study published last month in Nature Microbiology suggests the last common ancestor of all living cells fed on hydrogen gas in a hot iron-rich environment, much like that within the vents. Advocates of the conventional theory have been skeptical that these findings should change our view of the origins of life. But the hydrothermal vent hypothesis, which is often described as exotic and controversial, explains how living cells evolved the ability to obtain energy, in a way that just wouldn’t have been possible in a primordial soup.

I remember in High School the teacher describing water as a solvent. Later water was described as a building block of life. I asked for clarification, I got back a blank stare and the subject was changed. Just thinking out loud...
Life was only made possible once a fatty membrane was formed in water. This part is already pretty well established.
a tip: you can watch series on flixzone. Me and my gf have been using it for watching loads of movies recently.
These people talking about flixzone all have accounts created one month ago. I’m reporting them
It can be both, no problem. Solvent in this instance just means a liquid where other substrates can act and do stuff

As a stem cell biologist, I think it's so amazing that we still can learn so much about the origins of life. To think how such a beautiful structure like DNA is so stable but can also be slightly modify over time to allow evolution was created is just mind-boggling. Then we also have enzymes which catalyze concentrated reactions in our cells and allow us to create ordered structures in the unordered universe (I made a video about this). Just last week I had an online seminar given by a professor who's trying to create life forms from scratch and that research is so fascinating!
Unordered universe? Depends on your viewing angle, friend.
yeah it does make me laugh. I can see why people think the universe looks un-ordered but its crazily ordered.
when you say scratch? are you saying taking the basic building blocks & putting it together? Are not the blocks something already provided? Would not the true sense from scratch be to create those building blocks in the first place?
All micro states are equally probable*
I mean given all our knowledge & technology now vs the supposed primordial soup open to the chaotic changing environment surely we would of been able to ignite life by now?
Ohh that puddle must be the one featured in Hitchhiker's guide to the Galaxy😂
If hitting a puddle with starlight is all it takes to jumpstart life then life must be in abundance in the cosmos.

I was under the assumption that rockpools were already the general consensus, not the open ocean. That's what I was taught at university twenty years ago at least...
One of the newer ideas is that life started in hydrothermal vents.
@@KRYMauL Yeah... that was also a recognised possibility twenty years ago, but I guess that still counts as new on the scale of the evolution of life. Also volcanic lakes, and comets.
@@greenisnotacreativecolour Actually I meant the most recent version of it that was given in cosmos possible worlds. The one I kept hearing in AP bio was that the chemicals just formed by hydrothermal vents, but they recently added that you need porous volcanic rock.
Although, the Geyser hot springs makes far more sense than tadpools.
@Claire H Hydrogen it helps to know the answer, but more likely than not life was not an isolated event it was a series of events that converged. Also, panspermia is another origin that is possible even if it just kicks the can forward.
@Claire H Hydrogen
I agree. Origin of life research is showing we need a mixture of Hot, ambient and very cold conditions along with dry, wet, and evaporating conditions as well as ingenious methods of refinement, filtration and vacuums to achieve some of the building blocks thought to be required for life.
And these all have to be very close to each other for the chemicals to interact before they break down.
I don't think they have any idea yet how the early earth made sugars thought to be essential for life.
The early earth must have been very very clever.
Hasn't the "primordial soup" always been depicted in pools and shallow water? In movies it's always shown as some kind of bubbling pit not in the ocean...

I don't know if mud and clay are the same but, yeah, pretty much (sort of) - montmorillonite clay specifically.
This “water paradox” doesn’t exist. Yes it’s true water degraded proteins. But remember, the first “cell” (just RNA and phospholipids) had a phospholipid bilayer (precursor to the cell walls and cell membrane). This membrane of phosphates and lipids had a hydrophobic exterior that prevented water from entering and degrading the RNA and proteins.
Thats not true at all... First, we dont know If there was an initial phosfolipid bilayer. Life probably origined as something even more "simple" than a virus, so the initial coat could have been proteinic or even mineral or a combination of both... (Maybe phosphates as its seem they were pretty important)
In the first chapter of the Bible you can find the story of the creation. Just think about it a bit.
@@Hansulf you should really work with me.
@@brandonsballing826 what do you mean? Btw, nice Playlist you got there.
Phospholipids would have come after a pure lipid bilayer vesicle "membrane" in the first protocell. Before that, naked strands of RNA might have replicated without protein or fatty acid coatings. RNA viruses are nucleic acid strands with protein coats (some also have phospholipid capsules derived from their victim cells' membranes).
Life probably went through a membraneless phase.
1:40
What? Nucleic acids aren't made of proteins.
Histones are proteins though
@@gynaecographer
Histones aren't part of nucleic acids though. They're just associated proteins.
But remember, the oldest "enzymes" are in great part "ribozymes" made of RNA. This is the case for very conserved organuls like ribosomes (which sintetize proteins from RNA). So RNA replicating RNA was probably the original thing.
Correct but nucleic acids are made by proteins. Maybe she said 'of' instead of 'by' by mistake.
Love her enthusiasm when she is talking about all of this exciting stuff!
Curiously, in the final episode of Star Trek The Next Generation there was a multiple time travel arriving to the beginning of life on Earth... in a puddle.
Also, a puddle makes sense. Quiet water, not strong currents and waves, make for a friendlier environment for tiny molecules to combine and work together as a living entity.
great video. I'm a high school biology teacher and will definitely add this to my Miller-Urey experiment lesson. Thanks for the clear explanation.
".. not everyone is in agreement on this."
Understatement of a lifetime.
LOL. Now this gives a new twist to Douglas Adams' "Sentient Puddle" fable.
At 1:40 you mention H2O breaking down molecules like proteins (hydrolysis), which is correct. However at 1:43 you mention that DNA nucleic acids (nucleotides) are also made of proteins... I hope you meant that proteins (enzymes like DNA polymerase) help form the DNA and RNA into specific sequences, rather than being made from them.
An experiment I want them to make a video on is “Biparental mtDNA inheritance”.
Ooh does the mitochondria from the sperm cell get inherited or something?
@@monkstink1913 Technically, the mitochondria from the sperm actually goes into the zygote. It’s just that the mitochondria in the egg outnumbers the mitochondria in the sperm to a insane level so that the mitochondria from the sperm doesn’t really affect anything differently.
Like how your mom is also your dad's sister?
@@ricksanchez7250 HALF SISTER
Are you talking about Cytoplasmic Inheritance. I learnt that it's only from maternal side(uniparental) i.e. only the Cytoplasmic genes (genes outside nucleus, as in mitochondria or chloroplast) from female gamete gets inherited as they are the max contributor of cytoplasm for zygote
There’s nothing more refreshing than drinking cool water. I often look at it, perfectly clear and harmless looking, and wonder if it would be like drinking gasoline for an extraterrestrial.
By FAR the most convincing scenario for abiogenesis I’ve heard involves alkaline hydrothermal vents on the ocean floor, as laid out by people like Nick Lane, Mike Russel, and others. Through a process called serpentinization, ocean water is drawn into the mantle, heats up, reacts with the rock, and billows back up as hydrogen ions (protons) along with tons of dissolved minerals, which precipitate out to form the lattice-work, honeycombed vent structures.
The mineral rich, ion rich brew flow through the millions of tiny chambers (which are about the size of single cells), a very interesting set of conditions are generated, namely a series of gradients between the inside of the vent and the ocean environment outside: a temperature gradient, a PH gradient, and a proton gradient. And it turns out the most fundamental thing about metabolism and energy use in all living organisms on earth - no exceptions - involves the use of a proton gradient across a membrane. The internal chambers also provide the ability for all kinds of molecules to accumulate in high concentrations. The vents provide an energy source and plausible explanations for many of the strange quirks of biology. It fits. A warm little mud puddle or tide pool or hot spring provides none of that.
A bit vague, don't you think?
interesting theory, kudos
Listen to Dr James Tour you will the get the real answer
Nobody really know how life started
“...now with nucleotides and protein and fat precursors we’ve got all the moving parts to get life going...”
Not true, just having nucleotides, proteins and fats does not mean that they are automatically in any mechanical configuration. Having steel and rubber does not equate to a wheel and tyre.
The bear minimum needed for life to get going is actually staggering complex and coordinated. You need an engine to produce the energy needed to overcome entropy (with all its many molecular machines to keep it running), a repair system (with all its many molecular machines to facilitate the reversal of wear and damage), and an information system to coordinate it all (with all its many molecular machines to read, write, copy, correct and process the highly specific information). That’s far from just nucleotides, proteins and lipids!
Yes I agree, but with billions of these chemical reactions happening, again and again. There is plenty of scope for those configurations to be drawn together naturally. Also it is happening repeatedly for billions of years.
I mean we know it has happened, we are just working out the exact how, of it.
My cousin definitely came from a puddle. You need to see this dude to really understand.
So is there a possibility that life has started on beaches? What a medaphor when you think about looking at the sea from the beach has such a calming effect.
hmmm, make sense

Wet dry cycling sounds probable to me. Way back when, it was was hotter, and lighting struck often. Think of it like tropical conditions but everywhere and more extreme. Giving the soil at the time exposure to pretty much every element. Volcano eruptions would have been common place too

Mid latter part of the video about "bubblin' up brew" made me think about the theme song the "Beverly Hillbillies" tv show.
Since the 80s I have never heard that life started in the ocean and crawled on land. It was always speculated to be a puddle.
A puddle would be entirely too small.
Maybe a secluded inlet with a stretch of alternating shady and sunlight areas.
Maybe a lake.
Puddle doesn't stick around long enough...but I can see where your mechanism of gradual unalterable approaching arid condition might eventually force basic-most living things to survive by way of the earlier dead used as shell protecting and or somehow going into recesses in the soil.
@@lancethrustworthy I think a lake would still be too much water. Guess again.

Hey Seeker! I have a weird Question I need you to try and answer.
We often hear in wildlife documentaries that different species have different mating seasons and different time it takes for the offspring to reach adulthood.
I would like to know if humans ever followed such cycles and what impact it could have had on Evolution?
So the possible origin of life might have been around wetland-like areas and coasts, possibly even volcanic ones - which might have provided some of these essential building block. Always cool to see some kind of progress being made. Makes me feel like we aren't that far way from joining up those earliest missing links, from non-living matter to simple self replicating life. When do you think it'll happen?
Outside of Scripture, no one knows how life can arise from lifeless chemicals and such. No ideas are being seriously looked at.
Her voice makes me feel safe
I think it takes a lot of time for a living phenomenon (self-replicating) to develop. But not only does it take time for a living phenomenon to develop, but also for the environment to be relatively stable during a given time of development.
The gravity of Mars (by its mass) is too small to prevent the escape of the atmosphere and water. Therefore, there could not be a stable environment for the development of the living phenomenon for so long.

I'll bet the script say "... things that are making proteins, DNA and RNA." And she read it as "... things that are made of proteins, DNA and RNA." And nobody caught it.
I vote hot spring! Many other organic molecules could've started near some. 😅
That sounds like going back to what I remember reading in the 70s - as a teenager interested in science so it was both what books I could find in the library and what science articles there were in the newspapers and magazines I had access to, but for me at that time always popularized science - when the idea was, as far as I remember, that most likely origin for life was shallow pools. Some what I read talked about tide pools, some others just pools.
The dry-wet cycle seems new, though. I have no recollection of that being mentioned back then.
Awesome video.
The biggest question I still have is: "where did the instructions come from?"
A couple of years after the famour Millar-Urey experiment made amino acid rich goo, Watson and Crick discovered DNA and found that not only do we need the "building blocks of life" but there are thousands of pages of instructions in each cell telling it how to construct a copy of itself!
It's very interesting to hear how chemicals form and bond - but it still doesn't explain life.
If a radio message reached us from Alpha Centauri with thousands of pages of instructions on how to make a machine beyond anything humans have ever built - I would not be satisfied with an expalination on how radio waves work and where Alpha Centauri is. - My question would still be: "Who sent us this information?"
The earliest life didn't even use DNA. And proto life certainly didn't and these things were WAY more primitive and simplistic than even the most basic single cellular life today. DNA (that huge instruction book we have today) evolved over a very long period of time as life became ever more complex.
@@EmeraldView How do you know that? What is the scientific evidence? Has it been demonstrated or observed?
@@drewrommel Life didn't simply appear with DNA ready to go. Unless you are suggesting panspermia which would have seeded life on earth from elsewhere. Though that DNA based life would have had to have evolved from something more simple. Or unless you're suggesting that some all powerful complex thinking doing entity just magically always existed outside of space and time, just.... because, and then magically poofed DNA-based life into existence.
We don't know exactly how life on earth came about which is why it's an area of continual study that is getting ever closer to the answers. We're hypothesizing and even finding more ways to demonstrate how the building blocks of life can arise spontaneously though natural physical and chemical forces and then assemble themselves into ever more complex and presumably eventually self-replicating molecules though a process of 'natural-selection' not all that unlike the natural selection that allows life to change and become ever better at doing what it does over vast periods of time.
@@EmeraldView I think the complex thinking entity. It fits the evidence and requires less faith.
Complex machines require intelligence. All our experience and experiments tells us this. it is scientific. (And we are talking about a machine more complex than anything humans have ever designed.)
To imagine that it formed by - (as you seem to have faith in) a yet unknown accident that doesn't include a designer is ignoring the evidence. I follow the evidence. I don't have your faith.
Ha. The series finally of Star Trek: The Next Generation nailed it. Small puddles of goo!
when have you ever observed any puddle of goo that had any potential of itself? you cannot even drop DNA already formed in there, the DNA would be degraded into goo itself
I was thinking about that glad someone also did to
thank you Maren and all the team for this fascinating video. Do any of you guys have some suggestions on books regarding this topic?

what about Wachtershauser's theory that life began in oceanic hydrothermal vents on the ocean floor at extremely high pressures. Also, the vents are lined with pyrite, which has unique chemical properties.
Also you have to consider that the original organisms may have used elemental sulfur instead of oxygen
the latest hypothesis that I recall that made life on earth possible, was the Theia Impact. When a smaller planetoid smashed in to earth which was responsible for the formation of our moon, which led to the tidal mechanics we experience forming. Or is this about way later than that ?!

Also she misspelled "abiogenesis" a bit earlier; glad other people got these mistakes...
I have been saying this for years. Everyone researching the origins of life seemed to forget that water dilutes chemicals, and breaks them down. Hot springs and thermal vents are too thermally active, violently mixing everything in a boiling solution that rapidly disperses chemicals. This sort of environment would not to allow the formation of complex compounds. My theory is that the primordial materials probably formed in a thermal region, much like Mammoth Springs at Yellowstone. You have slow-moving warm water loaded with chemicals moving through a series of terraced pools. The travertine deposits would also provide large surface areas and nooks and crannies for nascent life to develop while avoiding stagnation and the build-up of toxic/adversely reacting substances.
Leave it to science to just throw their hands up and go, “well... you know it could’ve been this, but also could’ve been this, so we just really have no clue”

“It didn’t come from a pool of water, it came from a puddle.”
the main problem in Miller-Urey experiment is aminoacids doesn't form polypeptide chains in water or other solutions. The living cell to produce that kind of reactions spending a lot of energy and have a lot of other mechanisms to assist that process. So the question about position Miller-Urey experiment doesn't mean that it answers the question "how the life begins?". I'm sorry for mistakes if i made, i'm not write or speak english that much it's need to be.
The big question is why even those chemicals started acting like living and moving ,did they get to the some kind of Mysterious configuration of their atoms which activated some unknown energy caused origin of life or they triggered some new type of unknown particles under certain conditions ?.
Thats so smart!

Just want to give kudos to the work of Bruce Damer and David Deamer who have been developing we-dry cycle driven life emerging theory for a number of years. Bruce was a guest on the Joe Rogan’s show couple years ago.
At 1:44 you say DNA / RNA are made of proteins, not sure if you meant to say they are made BY proteins. But even so, according to the RNA world hypothesis life started as RNA and RNA only, and only later different cell functions were taken up by more stable DNA and more versatile proteins. As far as I know the RNA world hypothesis is relatively widely accepted.
RNA is very unstable. It needs to be stored in freezing conditions to last around 80 days.
At room temperature it lasts around 2 days.
RNA also has a mass transfer problem for self replication.
The best we have seen in the lab under carefully controlled conditions which were unavailable on the early earth is around 7%.
Nowhere near enough to be self replicating.
Since there was no land above water when life began on earth I would say this one is pretty conclusively settled. Life started in water, as demonstrated by every piece of archeological and biological evidence without exception. This paper does absolutely nothing to make its case
We may have been wrong about a LOT of things
You could say that
Why have I always known it was small ponds? Or puddles?
Great episode.
life probably developed in inland freshwater lakes/swamps, or hot springs along the land boundary. then gradually moved onto land and oceans.
Maren the love of my CZcams.
Why doesn't it still happen.. earth can support life still so why dont we see new organisms coming out the oceans .. 🧐
Because you should have a life span of 200 million years to see it. I think you're a bit younger than that, aren't you?
Once life appears and takes over it consumes mostly anything that could be a precursor. Life is a pretty aggressive phenomenon

i doubt the abiogenesis experiments using seawater replicated closely enough the chemical composition of primordial oceans, specifically the CO2 to oxygen ratio.
interesting to think that archaea may be the progenitors of prokaryotes and eukaryotes, they contain extremophiles which would accommodate ideas about extreme conditions. So, perhaps prokaryotes and eukaryotes evolved from them?
