Life crawled out of the oceans onto land, right? New research suggests that this popular theory could be wrong.

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.

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!

@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.

This “water paradox” doesn’t exist. Yes it’s true water degraded proteins.

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.

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.

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?"

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.

I'm still waiting for the day scientists have the A-Z product, or go through the ABC and show the world how they made their first living thing. I _hope_ it will be within my lifetime. Creationists will go nuts, but I guess they then will somewhat cool down, and say something like _"well it's not exactly a human",_ or something along those stupid lines. Abiogenesis is more or less religion's last stance. It would be fun to get rid of at least most of it.

@@adrianstoian2484 I don't have to. Already at Verse 3 is where the bible shows its _first_ spark_ of great ignorance. From there and onward, the bible truly _shines_ in this confident _unenlightened_ guesswork many believes to be revelation, but no. The bible does not have a clue about what light is, how it works or behaves or anything.

Maybe I come from an alternate universe or something, but hasn't this been the implication of the Miller-Urey experiment all along?

what about Wachtershauser's theory that life began in oceanic hydrothermal vents on the ocean floor at extremely high pressures.

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.
