Scientists Are Cracking the Primordial Soup Mystery

Soulskill posted about a year and a half ago | from the life-here-began-out-there dept.

Science 278

derekmead writes "Scientists have had a basic understanding of how life first popped up on Earth for a while. The so-called 'primordial soup' was sitting around, stagnant but containing the basic building blocks of life. Then something happened and we ended up with life. It's that 'something' that has been the sticking point for scientists, but new research from a team of scientists at the University of Leeds has started to shed light on the mystery, explaining just how objects from space might have kindled the reaction that sparked life on Earth. It's generally accepted that space rocks played an important role in life's genesis on Earth. Meteorites bombarding the planet early in its history delivered some of the necessary materials for life but none brought life as we know it. How inanimate rocks transformed into the building blocks of life has been a mystery. But this latest research suggests an answer. If meteorites containing phosphorus landed in the hot, acidic pools that surrounded young volcanoes on the early Earth, there could have been a reaction that produced a chemical similar one that's found in all living cells and is vital in producing the energy that makes something alive."

There is no scientist in the world who would ever describe it this way. For fuck's sake.

Au contraire, mon frere. I've had story submissions accepted (IANAWriter) and the editors here always fleshed it out and fixed it, making it palatable for the front page. (Thanks to Soulskill for fixing my latest)

Typos happen in all media, even The New York Times. I assume that the eds are busy ''behind the scenes", like setting up upcoming stories, formatting comments (who knows?) and 'shit happens' sometimes, the 'shit' gets fixed. It's a great tech info site, and I've learned a lot reading here over the years. The editors here care about the site, and don't always get the applause they deserve, that's part of the job, I guess.

We'd be searching for game-breaking glitches and backdoors all year if that happened. We wouldn't really know if it was a real one or a fake one if we found one, but the intellectual exercise itself and the world of possibilities that is opened would be amazing.

We're doing that already - we call the processes science and mysticism, and every backdoor we discover opens the path to the creation of new kinds of mods. Really the only big difference would be the search for cheat codes, and a lot of religious people are already convinced they've found some of those as well, they just won't know for sure until they reach the game-over screen.

Eh I guess.

Because, based on the human race's history, that knowledge is going to be abused in ways that I haven't even imagined as of yet. I honestly don't think we can ever know the exact mechanism of how we came to be because we do not know the conditions under which life began. And have no way of ever knowing it. I'll be the first to admit that I could be wrong about the impact this knowledge will have on humanity if it is ever definitively proven, but from my perspective at this moment, I just don't see it.

Immerman (2627577) | about a year and a half ago | (#43442941)

Actually we're already at the threshold of creating life in any form we wish - I believe it was a year or so ago that someone successfully implanted a fully synthetic genome into a bacteria and had it develop and reproduce as a new organism. There are (presumably) limits as to how far you can reshape a given cell using the technique, but given the vast spectra of life on this planet we will probably soon be able to create almost anything we can imagine, though some of it may take several generations of successive modifications if we wish to drastically overhaul the internal cellular processes.

Knowing how life (may have) first arisen is largely an intellectual curiosity, much like anthropology, paleontology, or any other historical study. Knowing how we got here may give us some degree of insight into the forces that drive us, but our interpretation will be limited by our current understanding of the processes involved, and that understanding will have already opened the door to any new technologies.

It changes a lot. Just as the tip of the iceberg, it changes a lot in regards to various Religions. It will help prove (or refute) our current theories of things such as Evolution.
And it will be a massive score for biological research Sciences. Which might very well result in you not having to die.

Well, if /. wasn't here, I would probably be back in the electrical department testing electronics. But since it does exist, I'm not. Do all of you honestly believe that once we find out the exact mechanism that creates life that it will suddenly change everything? I will still have to eat, drink, poop, etc. I live near a rather large metropolitan area. Social things pass me by all the time. It isn't going to change the fact that I have to have a job, or that I need to put gas in my car, or need to sleep this evening. If a whole bunch of believers are affected by this knowledge, that is their issue. Not mine. Fads come and go. And yet, everything remains the same. There will still be illiteracy, poor people, homeless people, hungry people, people @ war, crime, whatever. This knowledge will not change the face and the actions of humanity as a whole.

Re:Here we go again...... (1)

Immerman (2627577) | about a year and a half ago | (#43443069)

Evolution is already proven as an ongoing process, and if someone doesn't believe in the fairly well established historical evolution of Man from apes, much less small shrew-like creatures that shared the Earth with dinosaurs tens of millions of years ago, I seriously doubt they'll be convinced by theories of how life first arose hundreds of millions of years before the beginning of the geologic record (Earth's crust gets slowly recycled, a process which has mostly erased roughly the first billion years of geologic history).

So long as people accept faith as something to be held in spite of solid evidence to the contrary, there will be no hope of disrupting their perception of the universe. And for religions whose creation myths are embraced *as* myths, well there's already no conflict - the story of how the elephant got it's nose isn't actually about elephants and alligators, those are simply characters used to communicate a superficially unrelated lesson.

Re:Here we go again...... (-1, Troll)

n3tm0nk (2725243) | about a year and a half ago | (#43443111)

I agree that evolution is a fact of life. However, there is no concrete evidence showing that man evolved from apes or a shrew like creature. anyone who believes that humans are direct descendants of apes are using faith as a tool as much as one who believes in religion X.

Re:Souless zombies (1)

Philosophers refer to it as magic meat (as in if you assembled a completely identical clone of yourself--a meatbag--and you didn't consider it to have a soul, then your soul would only be granted by the fact that you are made of magic meat and the meatbag over there is just regular meat). Christians refer to this as "life begins at conception". Those who reject the magic meat hypothesis consider life to have begun billions of years ago, of which any human is only a small part and process. Rejecting magic meat essentially means that you rejected the idea of having a soul.

Stop acting as if like was an on/off switch! (3, Interesting)

Anonymous Coward | about a year and a half ago | (#43442433)

There is no "alive" vs "not alive"! It’s a gradient! And there exists, and existed, every step in-between!
Why is this such a unknown thing in Leeds? Here in Germany, it's already accepted common knowledge.

It's as if they were completely blind to prions, viruses, and other things that are in-between what they like to call "alive" and what they call "dead". Or, and this is what I think, they are deliberately and obsessively trying to force a hard distinction because their rigid (and in this case willfully ignorant) world view is built on it.

You get proteins (not DNA) of bigger and bigger size forming from the same basic building blocks. Like Prions and the normal proteins of our bodies. Now get one that is by accident capable of self-reproducing (probably with the environment and other simpler proteins already doing most of job), and voila, you have something alive enough to fit your arbitrary (and varying with the mood of the day) lower limit.

This is ridiculous and embarrassing for people who call themselves scientists.

I go even further. I think some of the machines we build are drifting into the intermediate zone.

If you think about a 737. It does a few things that are interesting. First of which is has a thermodynamic engine. All hard living things power themselves via thermodynamic engines. It's has a primitive homeostatic control. It can fly its self. Could with a little work take off, fly and land by itself. It's fairly obvious now that all of this could be improved. And actually in some cases like high altitude flight at high speeds, the plane has to fly itself, a human just can't do it.

It doesn't reproduce by itself, requiring humans to make new copies. On the other hand a lot of flowering plants need another species in order to reproduce.

Why? Because, as any programmer can tell you, the beneficial code combinations are dwarfed by the destructive combinations by many, many orders of magnitude. Things can never get to the self-replicating stage because they are guaranteed to be destroyed before anything vaguely interesting can happen.

There are two realms. In one, the physical realm, you find things that can be created and destroyed. In the other, you find things that can neither be created nor destroyed; they just are. The blue and red colors that you consciously sense and the flavors that you taste from food do not exist in the physical world, even if you think they do.

I understand the point you're trying to make... but to play devil's advocate: the blue and red colors you sense and the flavors you taste exist in the physical world... just measure the chemical and electrical activity in the brain as the photosensors and chemical sensors react to the incoming stimuli. It can all be measured, and is similar for all people. That's all in the physical world.

If we understood the brain well enough, we might also be able to isolate the concepts themselves -- but as those would be stored uniquely in each brain, we're still a long ways away from figuring that part out. Doesn't mean it doesn't exist though -- just as easy to say that the Higgs boson doesn't exist in the physical world (which, in a way, it doesn't).

... and exactly how many multi-million-year simulations have you run that prove the negative you assert, that never, once, ever, a 'beneficial code combination' escaped destruction by the 'destructive combinations' long enough to make a few copies of itself? Or that it never can?

I notice you specifically said ".. complex life". Well of course, no one asserts the primordial soup went from a few simple molecules to "complex life" in one magical step. The crux is that systems can grow in complexity in small, incremental steps.

Genetic algorithms have already shown that natural selection can operate on pre-life patterns. It works like a ratchet, each step can build on the next up the "complexity" ladder.

Never say 'never'. Never say 'guaranteed' either. Especially when it comes to nature, given geologic time. It if doesn't out-and-out violate the laws of physics, who are you or anyone else to say it couldn't happen, given the right conditions and enough time?

Even though you are being modded up by the usual suspects and I am being modded down, everything you said above is pseudoscientific crap. Sorry. Genetic algorithms have already shown that natural selection can operate on pre-life patterns? This is pure unmitigated BS on the face of it.

The idea that a chaotic system can give rise to complex life is in the not even wrong category. I am not saying that the probabilities are small. I am saying that the probability is exactly zero.

Did you miss Darwin's Theory of Evolution? It's kind of obscure, you might not have heard of it yet. Anyway, it demonstrates one mechanism that simpler life can become more adapted to its environment and become more complex. So the idea that chaotic systems can't give rise to more organized systems already has a big widely-accepted contradiction.

Scientists Are Cracking the Primordial Soup Myster (2, Interesting)

danielpauldavis (1142767) | about a year and a half ago | (#43442591)

This only works when someone explains the non-existent mechanism by which ONLY laevo-rotary DNA molecules were selected . . . because any random assembly not only has the molecule as quickly disassembled but also randomly assembles an equal number of laevo-rotary and dextra-rotary DNA molecules. The latter are not only useless but dangerous to life. Thus, these notions about space rocks are only distractions.

Isaac Asimov wrote an essay about this, "The Left-Handed Universe". The book, of the same title, in which it was published is a collection of non-fiction science essays; "Why does ice float?", "Why is the night sky black?", etc.. I don't know if Asimov's ideas in "The Left-Handed Universe" are correct, but Asimov is always fun to read anyway.

The latter are not only useless but dangerous to life.

The probability for a DNA molecule to appear without having used a pre-existing DNA molecule as template is tiny. Maybe it has only happened once in the entire lifetime of the Earth. In that case the orientation is completely random. It would be 50/50 for one orientation or the other. In that case if we ever find DNA based life elsewhere, the orientation of DNA molecules can give hints as to whether life has evolved independently or spread from a common origin.

It may be the probability is higher, and DNA created from scratch has happened more than once in the lifetime of the Earth. But if hundreds of years passed between the first two times it happens, it could be that life had already spread across the entire planet in the meantime. In that case the second DNA molecule could have caused some havoc in the area where it appeared, but eventually life around it adopted enough to wipe out the DNA molecule, that did not fit in.

Maybe both variants existed for some time, but during the evolution of life, one variant got extinct.

It isn't random, it's chemistry [talkorigins.org] . You were informed of this the last time you posted on the subject.

Hydrothermal vents (1)

DigiShaman (671371) | about a year and a half ago | (#43442635)

I've always understood life to have arisen from or near hydrothermal vents. These cells thrived via a process known as chemosynthesis.

I'm sorry, but the idea of valcanos, soup ponds, meteorite, and lightning bolts sound too wacky. Such an environment is also too unstable for delicate life forms to survive IMHO.

Most scientists don't know shit about the origin of life. It's educated guess work.

Re:betta fix that first sentence (3, Insightful)

You could argue that all of science is "educated guess work": taking what you already know, and making a hypothesis about something you don't. Make a guess and test it, rinse and repeat.

No matter how it happened, it happened fast... (4, Insightful)

staalmannen (1705340) | about a year and a half ago | (#43442799)

One thing that has always stunned me is how fast after the Earths crust had cooled down that life appeared. * http://en.wikipedia.org/wiki/Timeline_of_evolutionary_history_of_life [wikipedia.org] This if anything indicates that the determinig events leading to a self-replicating unit (perhaps RNA) must have happened pretty fast and thus been very probable. Take this perspective to the stars and all the potentially habitable planets out there and the universe is teeming with life! .... pretty cool if you think about it.

Re:No matter how it happened, it happened fast... (0)

If it's so probable, then why isn't there evidence of more than one independent kind of life here?
Is there only one way it can work?

Theories without proof is just religion (-1, Redundant)

genocism (2577895) | about a year and a half ago | (#43443059)

I understand the challenges of putting evolution against the scientific method... but something like this seems like a no-brainer. I want atheism to be based on fact. Theories without proof is just religion. These guys are scientist right? Let see them do some actual science. Create an environment that proves this theory to be correct. If it doesn't work modify the theory and try again.

So everyone knows plate tectonics explain the formation of the planet, or do they? The expanding earth hypothesis is ridiculed, yet we have been and still are bombarded with megatons of meteors for billions of years. How on earth has the planet not been expanding?
