The Miller-Urey experiment was the first attempt to scientifically explore ideas about the origin of life. Stanley Miller simulated conditions thought be common on the ancient Earth. The purpose was to test the idea that the complex molecules of life (in this case, amino acids) could have arisen on our young planet through simple, natural chemical reactions.
The experiment was a success in that amino acids, the building blocks of life, were produced during the simulation. The finding was so significant that it kick started an entirely new field of study: Prebiotic Chemistry.
Scientists now have reason to believe that the gases used in the Miller-Urey simulation were not actually the same as those of the ancient atmosphere. Because of this, many experiments have since been done, testing a wide variety of atmospheres and different environmental conditions. The results are overwhelming: the molecules of life can form under a wide variety of ancient Earth-like conditions.
Many questions about the origin of life remain to be answered but these findings give strong support to the idea that the first living cells on Earth may have emerged from natural chemical reactions.

Here are some notes I made on this video if any of y'all need • The idea of rats and maggots suddenly appearing to eat rotten food was called spontaneous generation. This idea stated a new scientific fact: “life must come from life”. • Darwin wrote that it could be possible to create life from non-living materials, these non-living materials are light, heat, electricity, etc. inside a chemical soup. • Alexander Oparin elaborated on this idea further by creating a step-by-step process of how it could happen (Simple Molecules to Molecules of Life (Biomonomers) to Macromolecules to Polymer Complexes to Metabolic Networks to Living Cells). He imagined all of these chemical reactions would happen inside a primordial soup. • These ideas were just speculation and needed scientific proof to be considered true science. Stanley Miller had an idea to prove these theories correct, he thought he could simulate the early Earth stages and observe what happened in the water to see the outcome. Harold Urley worked with Miller to complete this experiment. • They modeled tubes of water to fit the conditions of the ancient ocean and boiled it to mimic evaporation. They also added water vapor & other gasses like Methane, Hydrogen, & Ammonia, to simulate the Earth’s atmosphere. Also, they added a condenser to cool down the atmosphere, simulating rainfall. Then, they added sparks to simulate lightning in the atmosphere. This test was used to see if Oparin’s first steps in his step-by-step hypothesis was true. • After a week of the experiment being observed, the water turned black, and it was filled with complex molecules created by chemical reactions. This proved his first step in his theory correct. • This experiment was such a breakthrough that a new field of science research was created called ‘Prebiotic Chemistry’. This science was researching other methods of how complex molecules could’ve been created.

I think you posted in the wrong place. This is a video about chemistry, not logical fallacies. The entire point is that chemistry alone can create the building blocks of life without needing a designer or necessary being. Life is plastic to its environment, so of course things are going to fit hand in glove. Soda is not manufactured in 12 ounce cylinders then wrapped in aluminum - an amorphous fluid fills whatever its placed in.

[@EternalSilverDragon]

Cool video - great job explaining the Miller-Urey experiment. The only constructive criticism I would make is around Darwin's contributions stated early in the video. His theory wasn't called "The Theory of Evolution" - that's a misnomer making it sound like he came up with the idea of evolution - the idea that relatively simple life forms can give rise to more complex life forms. He did not. Evolution was observed and established as fact in the scientific community long before Darwin's involvement. But we didn't understand _how_ evolution happened. Darwin's theory was actually called "The Theory of Evolution by Natural Selection" and it sought to explain that evolution happens via a process he called "natural selection". It was one of multiple theories trying to explain the _how_ and his is the theory that stood the test of time and was best supported by the evidence found since.

[@oilcan3585]

farmers took advantage of selective breeding since ancient times and so darwin gained idea of selective breeding to come up with natural selection

[@daniellclary]

But did they ever continue that experiment to see if something actually forms from it? Just because you get a few molecules, does not mean they actually form DNA. It is a complex code needing a translator and power supply. nether of the three can exist without the other. If it was really that much a breakthrough, I would imagine they would have continued it till they created a single celled organism. Or at the very least a start of a DNA construction.

[@Zerepzerreitug]

Found this article about how the experiment fares out nowadays: goo.gl/0PG2fK The issue, it seems, is that while the Miller-Urey experiment is a good proof of concept for the creation of organic molecules out of simpler ones, the _specifics_ are not very good. That's because we now know more about the way the early Earth's atmosphere was like than in Miller's time, and those conditions are not ideal for this experiment to produce good molecules as it is designed. So it's seen today as a dead-end. So instead, scientists are focusing on other plausible methods for obtaining complex molecules and basically starting from zero as Miller did back in his day. Recreating scenarios such as deep ocean vents, comets, etc, and seeing which one is a better candidate.

[@daniellclary]

So why they not teach that then I wonder?

[@Zerepzerreitug]

daniellclary My guess is that it's a similar reason to why we learn about Pavlov's dogs or the Michelson-Morley experiment (which disproved the luminiferous aether). Even when the experiment is not too useful today, it was a big breakthrough back then, and became the foundation for a whole new branch in science.

[@redeamed19]

As it says in a video this was only mean to demonstrate the feasibility of getting organic molecules from non-organic molecules. It is unlikely that even at the time they thought they could just let this keep running and ever get an actual cell. This being because there are far more variables to be able to progress. Indeed as Arturo points out this particular method is not a plausible candidate for how it happened on earth but it remains a functional and relatively simple demonstration of the principal. A few competing hypothesis exist for the way it would have happened on earth, many of which have similar ability to producing organic molecules from non-organic molecules I recently listened to the audible book Life Ascending by Nick Lance. In which they he addresses experiments his team has been working on with laboratory representations of alkali vents from the deep seas . In these experiments, If I'm not mistaken, they see all the way through the generation of random strings of useless RNA. This is however only one of the proposed method for how life actually arose and much work needs to be done still in verifying the results of these experiments. This is why the Miller-Urey experiment is a better candidate for demonstrating the principal of organic molecules from non-organic molecules: something that at the time was viewed as not possible. This experiment is done, has been verified via repeat experiments, and answers only a specific question.. The Miller Urey experiment is perfectly valid for what it claims to demonstrate. It only falls short if you try to extrapolate more from it than it claims to offer.

[@andykimin649]

+aroseland1 this is wrong.. the experiment had excluded oxygen.. no oxygen no life...keep that in mind

[@aroseland1]

+andy kimin Can you explain that more? water has oxygen in it (H2O) so if they evaporated water in the apparatus then that would clearly put oxygen into the equation. Please let me know what you mean thanks!

[@andykimin649]

aroseland1 no dear.. Although there's oxygen in water, in equilibrium almost none of it is present as O2. That's very familiar from the behavior of water nowadays. Even when heated to boiling, water doesn't decompose and give off O2. but by electrolysis or Photochemical dissociation it can produce O2. but the experimet didn't promote these. therefore O2 was almost completely excluded in this experiment. :) It is easy to get confused because this experiment is misleading..

[@aroseland1]

+andy kimin Okay, maybe that is true. But the experiment is just to show how the building blocks of live could form, if it shows they could form in less ideal conditions (with out oxygen) then that further validates the idea that they can naturally form in unlikely conditions. And the experiment doesn't show complex living organisms starting, it just shows how you can get a simple chemical division under those conditions. So I don't see how the lack of oxygen would de-validate the implications of the experiment?

[@andykimin649]

aroseland1 OMG.. Let me tell you a secret. Miller knew there was O2 in the atmosphere. But if he included O2 in the experiment, O2 will oxidize most of the substance in the experiment and this won't produce amino acid :) so, he purposely exclude O2 to get the desired result. I won't call this experiment science...It was a fraud and a disgrace for science

So back when I was still a creationist I was dismissive of the expiriment's indication that organic material could be created from inorganic material with such ease, but I had another take-away from this experiment. When exploring outer space or terraforming lifeless worlds(I.e some worlds will likely have the ability support life but not happen to have it yet.) processes like the one in this could be used to create servicable quantities of basic biomatter out of completely inorganic matter, by processing the basic materials, then feeding the end product to microbes. So I was the annoying Bible-thumper getting into arguments with the atheist kids over the plausibility of colonizing outer space, only it was the atheist kids saying "There's no soil up there, so how the fuck we going to farm anything?" And I'm the one chiming in, "Hello! If the Miller-Urey experiment tells us ANYTHING, it's that we can literally make it out of materials that are EVERYWHERE!"

The part about soil... The funny thing is if there is an atmosphere with wind, there will be dust. If there is water, there will be erosion. To get soil out of that, all one needs to do is add the appropriate biomatter and microbes, and you have soil.

[@mickelodiansurname9578]

Well I'm not really sure about your idea there. Basic chemisty doesn't need very much energy and its rather small scale monomers that are produced. For larger scale things above the size of amino acids you'd need more energy. That means a closer sun or maybe a geothermal vent or something that heats things up faster. Then you have the problem of the waste product's. You have to get rid of the biproducts of all this chemistry or it micht in fact end up destroying the system. On earth there was no oxygen for example which isn't a requirement for life but it is for living thing with more than a few cellss. Multicelled creatures need lots of energy and oxygen is the only element we know of that can supply that energy in tge shortest pathway. Thankfully on earth the biproduct of early life was oxygen... It poisonous though. Despite your fondness of the stuff it will eventually kill you! Lol. So now you need yet more energy and pathways to stop the oxygen from destroying the system... So for a faraway planet to suppot life then it would need to have existing life! Its the life on earth that built the life support system for life on earth.

[@mystuff8602]

TonyTime elaborate?

[@nunyabisnass1141]

mystuff the only thing I can think of is a claim that the *original experiment only created toxic, left hand amino acids. That is only mostly true, because when the samples were retested with note sophisitaced technique, right hand amino acids were also found, albeit in small quantities. Even still, no one knows what the first life actually was, and if could have been produced from either left or right handed amino acids, or if it could use a combination of both. But aside from that, the experiment was only ever supposed to be a proof of concept, not a proof of theory.

So,basically, this experiment in fact did NOT create any life itself but just the necessary physical organic building blocks for material that may contain it if that was possible. Alright then.

[@birdmoney]

Good summary. We haven't reached a stage where we can create life, but this is just another piece of the puzzle. How long until scientist are able to simulate the next step of life?

[@dubola5777]

That doesn't disprove creation! Because you can combine things in a lab and make something out of them doesn't mean that's how life started in the beginning.

[@yeahkeen2905]

dubo la they didn’t combine things in a lab, they simulated earth and amino acids formed *naturally.*

[@lilyoyo77]

@@yeahkeen2905 But the Miller-Urey results were later questioned: It turns out that the gases he used (a reactive mixture of methane and ammonia) did not exist in large amounts on early Earth. Scientists now believe the primeval atmosphere contained an inert mix of carbon dioxide and nitrogen-a change that made a world of difference.

[@rexkraft_]

@@lilyoyo77 It was questioned with a better understanding of the enviroment of earth's ancient past, wich gave rise to better simulations of that enviroment, wich in turn resulted on improved experiments that produced new and and far more complex structures that could form the basis of early life on earth, wich further supported the hypopthesis of life coming from non life. I might be wrong, but you seem to be suggesting that this theory is inplausible because the original 70 year old experiment used as proof of concept was not accurate with our current understanding of the enviroment when life first appeared. But not without reason, abiogenesis is accepted as the most likely explanation for the origin of life. and if you do think all of this is wrong, you can present your reasoning and evidence to the scientific community and get a nobel prize

Why did you withhold the total failure of the experiment to produce Only left-handed amino acids? This video although enjoyable to watch, leaves much to be desired in the way of Truth.

[@athulkathul7112]

Life is mostly made up of left handed amino acids, right?

[@ChristIsKing0919]

@@athulkathul7112peace be with you ~ all living organism are made of entirely left handed aminos. Just one right handed amino will render the sequence lifeless. Yet this experiment always produced an outcome of 50% right and 50% left. Not producing the promising outcome hinted at in this video.

[@athulkathul7112]

@@ChristIsKing0919 No, we are made mostly out of left handed amino acids. But many biological processes use right handed amino acids. I think bacterial cell walls use right handed amino acids. It's that, left handed molecules were mainly selected over right handed molecules through chemical evolution. Funnily enough, almost all amino acids in our body are left handed, while sugars are right handed, so we have right handed DNA.

[@ChristIsKing0919]

@@athulkathul7112 the following can be looked up. It is a quote taking from the Smithsonian Magazine: "On Earth, the amino acids characteristic of life are all “left-handed” in shape, and cannot be exchanged for their right-handed doppelgänger. Meanwhile, all sugars characteristic of life on Earth are “right-handed.” The opposite hands for both amino acids and sugars exist in the universe, but they just aren’t utilized by any known biological life form. (Some bacteria can actually convert right-handed amino acids into the left-handed version, but they can’t use the right-handed ones as is.) In other words, both sugars and amino acids on Earth are homochiral: one-handed." Those bacteria your referring to must "convert" the right to left.

[@athulkathul7112]

@@ChristIsKing0919 I'm talking about molecules such as non-ribosomal peptides. Proteins synthesized by the ribosomal RNA are primarily left handed, and we're trying to figure out why but it's been pretty evident that it's likely to do with the structure of the ribosome rather than the molecule itself. However, there are peptides called non-ribosomal peptides in some, especially primative, biological systems which do in fact use some right handed amino acids.
