How to create life
October 17, 2008 7:28 PM Subscribe
In 1953 a student named Stanley Miller did an experiment showing that the simple chemicals present on the early Earth could give rise to the basic building blocks of life. Miller filled a flask with water, methane, hydrogen and ammonia—the main ingredients in the primordial soup. Then he zapped the brew with electricity to simulate lightning, and, voila, he created amino acids, crucial for life. Now, scientists have reanalyzed this classic experiment, and found that the results were even more remarkable than Miller had realized.
Actually, I think we now believe that the 'primordial soup' had a different composition, and that Miller's experiment wouldn't actually work with what we now think the early earth was like.

As a graduate of Unseen University in Ankh-Morpork, I must protest your exclusion of the first experimenter actually to give rise to life (with an egg-and-cress sandwich), Rincewind.

Indeed. It's sort of the crux of the article.
Which is, for the record, pretty cool.

For me, the Miller experiments permanently solidified my love of Science. Nothing made me more of an believer in learning than the knowledge that through experimentation we learned that we all emerged from a ocean of goo made by volcanoes.
I feel so frustrated when Ultra Religious people find themselves threatened these kind of findings. My frustration comes them seeing the delightful complexity/simplicity of the universe as a challenge to their faith in an almighty God. Life emerging at the foot of an ancient volcano sounds like the garden of eden to me.
I sit firmly in "you don't know, and neither do we camp." That doesn't stop me from being ecstatic at the discovery of pieces of The Puzzle in old musty abandoned boxes.

Has there been further research in this area? Have people tried this experiment using what we currently know about the composition of the early Earth's oceans/atmosphere? The article makes it sound like Miller did his experiments, everyone got excited, then it gradually became apparent that the details about the composition were wrong, and then everyone just dropped it until they discovered these samples. It seems bizarre that there isn't a long line of these kinds of experiments constantly tweaked as we learn more about the early Earth.

So we danced with amino acids and got self-replicating acids and then got proto-bacterium who danced with other proto-forms and got cells and danced with other cells and did the wastusi with intercelluar forms and then got photosynthesis (so CLEVER) and got then boogied with some mitocondria and some slutty Virii and then grooved some wonderful, random transformation and errors until we get the Brandenburg concertos?

Miller, working in his laboratory at the University of Chicago, demonstrated that when exposed to an energy source such as ultraviolet radiation, these compounds and water can react to produce amino acids essential for the formation of living matter.

Professor's Urey's early researches concerned the entropy of diatomic gases and problems of atomic structure, absorption spectra and the structure of molecules.
I have no idea what that all means but I'll be damned if I don't think Urey was a badass in his field.

Sangermaine,
Other factors in why the Miller-Urey experiment hasn't been followed up much in recent years:
(1) Amino acids occur in some meteorites, so they might have been delivered to Earth rather than made on Earth.
(2) As speug implied, amino acids are much simpler than proteins, and scientists have been focusing on how proteins, RNA, etc. originated.
(3) We still don't know that much about the physical and chemical conditions on the Earth at the time life began. For that matter, when life began is uncertain.

The most impactful discoveries in science aren't "eureka!" moments, but rather, things that inspire an "hmm, now that's odd..."
The amino acids-in-a-flask from electricity is cool; it the interpretation that's important (from the viewpoint of SCIENCE!) - if it can be achieved easily; then in the almost infinite universe it must almost positively have occurred many many many times.
Given that it occurs many times (and has been borne out from spectroscopic evidence that extra-solar amino acids exist), then that increases the odds that complex peptides may arise from amino acids. In an almost infinite universe, a number of complex peptides may arrange in self-replicating forms, &c&c.
Showing that each step (amino acids -> peptides or nucleotides -> RNA/DNA or lipids -> micelles, &c) can occur withoutthe invisible hand of the market the intervention of an omnipotent incorporeal being is more evidence that the nature of our observable universe can bring about the wonder that is life.
I wonder if most people really understand or even have a general feel for just how big the observable universe is. We're here because... we're here. We wonder at how life (heh, how does one define life?) came to be because we happened to be one of those odds that ended up creating life.

Micelle formation amazes people (even people with PhD's in biochemistry) but they're not exactly difficult to form. Soap + water = micelles. (I found myself thinking about this during a presentation a while back where the guy kept using phrases like, "these will spontaneously form micelles" with a tone in his voice that would have gone better with, "Now I shall saw this woman in half and, yet, she will be completely unharmed!)

Mm, interesting, I wrote about this over a month ago on a private list, well you never know how stuff spreads on the 'net. This is what I wrote.
Many of us have wondered altho' happy with the theory of evolution, how on earth life could have started in the first place.
A biologist adventurer called Lyle Watson who died recently, gave me a working hypothesis in his book Supernature.
Based on the discovery by Miller and Urey in 1953 of the spontaneous creation of amino acids.
http://en.wikipedia.org/wiki/Miller_experiment
Watson calculated that the odds for the amino acids just lining up in the right fashion, to create a self recreating molecule to be around ten billion to one. To get ones mind around how colossally high these odds are, just start tossing a coin in the air and realise you require ten billion heads in a row and you realise how impossibly long, these odds seem.
Back in the late nineties I used to be on an email list called the egoist list, on this list was a catholic philosophy professor called Dennis Hudecki. Dennis came out with the brilliant metaphor, that it was like blasting a scrap metal yard, high in the air and it coming down assembled as a 747 lol. This had us all stymied for a while.
Then I thought of a way to explain colossally long odds.
In the UK we have a lottery where you have to choose six numbers from 49, the odds that you would get all 6 numbers is, 13983815 to one, that is just a tad under 14 million to one.
Say just for arguments sake, you choose as your numbers 1, 2, 3, 4, 5 and 6 using these numbers gives you just as much chance as using any other six numbers.
What are the odds that your numbers would arrive in ascending order, ie first comes ball number one then ball number two then ball number three etc etc.
The answer is 13983815 * 6 * 5 * 4 * 3 * 2 * 1 which comes out at 10068346800 which is just over ten billion to one.
If this is how life got started on earth, it could make it very rare in the universe, if not unique.

@dollyknot: extending your metaphor, it doesn't matter if it's a ten billion to one shot if you play the game trillions of times or more. Just on earth, you've got a surface area of over five quadtrillion square feet and a time span measured in tens of thousands to millions of years.

There are other factors though, it has to be the right kind of sun, with a nice friendly Jupiter to keep the Shoemaker Levy's of this universe at bay, it is not just that the amino acids have to line up right and of course we need the right kind of moon. The environment has to be right, so that the amino acids can happily go forth and multiply.

There are at least 1021 stars out there.
And tens of trillions of planets.
It's been about 14 billion years since the big bang.
Earth is about 4.5 billion years old.
First life is at least 3 billion years old.
Complex life only a billion years ago.
Odds are pretty good that there is life out there.

Most animals are adapted to their environment, giraffes have a long neck for a reason yer know. We do it barse ackwards, we take the environment and adapt it to our needs, the enormous shame is in doing so, we reduce natures almost miraculous diversity.
So unless we can accept that we have evolved our skill not to steal an environment, but to create one, we are destined to spend the rest of our lives mired in guilt and shame angst.
So ok we head upstairs and start creating a new garden of eden, can we not start putting things back the way we found them here.
Nearly all the ingredients for life exist on the moon already, there appears to be a lot of oxygen on the moon and some hydrogen, put them together you have water + energy.
Taking the idea that humanity is evolving towards planting life in space aka moon, think a million years into the future close to here, life would be all over the place - think about it - the only evidence that there is life out there, is that there is life here.
It is an assumption that because there is life here, there *must* be life out there. The problem is there is very little evidence that life is up there, part from prejudice.
Basically we need to go and look.
So as to find out how common or rare life is in the universe.
