We May Have Just Unlocked a Secret to How Life Started on Earth
On August 20, 2019 by Raul Dinwiddie
This one’s real easy, you guys–super low
key, not really a big deal, it’s just this silly question that nobody’s really interested
in, it’s just like….how did life begin? Ok, obviously I’m joking. This is one of the biggest unanswered questions
in science today, and is the backbone of our burning questions about who we are, where
we come from, and if we’re alone out here. New research has now given us clues into how
exactly the fundamental molecular building blocks of life came together in the first
place. Because that’s the central question: in
the big puddly soup of pre-biotic earth–as in, earth before living organisms–how did
the perfect ingredients for life form, much less fuse together into something that stores
information and can replicate independently. A primer on how our living cell’s work:
A cell’s most important components are DNA, RNA and a ribosome. DNA codes for all of the essential information
about what the organism is and how it works, but it’s kept all safe and huddled away
in the nucleus. To take that information and make it into
actual stuff, like proteins, an enzyme called RNA polymerase copies sections of the DNA
and makes strands of RNA, which are a like one-sided version of DNA. These messenger RNA strands get sent to the
cell’s ribosome, where they’re converted into the proteins our cells need for survival. When scientists were first discovering all
this complex stuff, it became an even bigger question of how all this could have spontaneously
come together as a result of organic chemistry. To tackle this problem, some scientists suggested
that perhaps life as we know it now didn’t all spontaneously form at once exactly as
it is, it was probably a little simpler…maybe it was only RNA-based! This hypothetical situation is what we refer
to as the RNA world. But this track of thinking is based on the
idea that the self-replicating aspect of life is what formed first. And not everyone agrees. Some people think that metabolization, or
the ability to extract energy from your environment, must have come first, while a third camp thinks
that compartmentalisation must have come first, a primitive version of the different internal
pieces of a cell. These divisions in the scientific community
still survive, but as we’ve come to learn more about RNA and how it can behave, it’s
become clearer that it’s an essential part of the beginning of life, if not the first
thing that formed. This is because RNA can do a really exciting
thing. Not only can it contain information that it
can then replicate…but it can also fold itself up into shapes in which it can act
as an catalyst, influencing chemical reactions! When this was discovered, we realized it was
much more likely that RNA-based life could indeed have survived and replicated all on
its own…without the all the fancy add-ons we have today. So then we come down to the question again–how
did RNA form in the first place? Scientists have been on a quest to demonstrate
how all of RNA’s component parts could have spontaneously assembled, and new research
may just bring it all together. RNA is made up of the nucleic acids cytosine,
uracil, adenine, and guanine. A research team had shown a few years ago
that a set of five simple compounds could have given rise to cytosine and uracil with
nothing more than the addition of UV light, which there was plenty of on a primitive earth. A different team then showed a similarly easy
and plausible process for the formation of adenine and guanine from simple building block
elements. But no one had demonstrated that these two
separate reactions, producing all four RNA nucleic acids, could have occurred in the
same place at the same time…until now. A paper that came out in 2018 showed that
a simple set of molecules–oxygen, nitrogen, methane, ammonia, water, and hydrogen cyanide,
all of which would have been present on an early version of earth–could react to form
what we recognize as the uracil, adenine, guanine and cytosine. This work is the first experimental evidence
showing that the chemistry fits–these building blocks could have feasibly all come together
at the same time, in the same place, we saw it happen before our very eyes. There are still a couple of missing pieces
that we haven’t been able to recreate in the lab. For instance, how did each of the building
blocks come together to link them into the long chains that take them from nucleic acids
to actual RNA? And, keep in mind, while the RNA world is
the leading theory, there is some contention among scientists about the first inklings
of life on earth. Hopefully work like this will add to that
discussion, PLUS it does represent an unprecedented step forward in answering the most fundamental
of questions: how life began. For more on DNA and the craziness of life,

Hi everyone! You may have noticed this episode looks familiar and that’s because it is, indeed, a re-upload. With the help of your smart eyes, we were able to fix a minor error we had in the previous version when illustrating the transcription process, but don’t fret, it’s all good now. If you’re interested in knowing more about how RNA is made, and then synthesized into proteins, check out this link below! https://www.nature.com/scitable/topicpage/ribosomes-transcription-and-translation-14120660
Life started when the Old Ones dropped the God Emperor on Earth
I believe God made the earth and I stick with that
tell me why she look like miranda cosgrove
Started as apes, genetically modified by extraterrestrial beings + eating Psilocybin mushrooms and that’s how our cancerous species was born ??
I love Maren, she's the nice smart Jewish girl my Mom is always telling me to find lololol Mom never said she had to notice me back!
Someone explain where all water for the oceans came from?
New world unlocked!
Enter, religious nutjobs….
SEVERAL CHRISTIANS ARE TYPING.
Here's a censored summary that's safe for religious ears:
scientists believe life was started by a chemical called riboGOOOOOOOOOOOOOOODid
the big cloud man did it
You are musical i like that the mix of music and science https://www.youtube.com/watch?v=h70wnnmMBT4&fbclid=IwAR3Qmic8bAGXtKcKhsdc6qrqDMbc45ToD9rfrSQmkHjh4qOo7Iyn4X-Bqw4
You wanna know where we came from? Well here you go God. Congratulations you now know more that most scientists. Hurray
Y'all need some Jesus rip to your ass
Stfu version: You came from animal that ate another animal that took alot of shit, shit mingled with crap on the ground and POOF= LIFE
Duh the magic man in the sky made life.
Science is to be ignored when it contradicts my view of the world.
Please read my "Sheep herders guide to the universe"
Disillusioned Christians are going to be super pissed.
The egg came 1st ?
12 seconds of cringe.
How did life get here? God put it here. Simple as that.
I'm here to see all the scientific experts in this comment section.
So another theory that people will claim is fact?
The earth is a flat petri dish on a dinosaur riding on a giant galactic space station
If only 4 elements required, then it's quite possible that with vast possiblity of earth like planets present on goldi boi zone… Life may be thriving there…
But there no aliens coming around cuz still no one is advance enough to break the time law of physics travelling great distance
It's like just a limiting barrier for us, we can't just make shift a teleporter
408 creationists didn't like this video
Any scientifically thinking person that ever admired someone for a theory or invention, then look at the complexity and genius of life and still think there is just materialism and causality behind it, is a hypocrite.
We find out how, then what? Whats next? What do we do? Is that it? Bc if it is then who cares
Quantum entanglement magic!!!
Cool!
But Let's say we descover that life started in a big messy molecule pool… what do we do with that info?
Does it address our real world issues? Does it make us a better people? It won't even get rid of religion since religion isn't fact based
Close.. possible even… instead of the likelihood of this happening being a grim 1 in 10 to the power of 100 it's a much improved 1 in 10 to the power of 99.
What about the 2nd law of thermodynamics? If you don't know what that is it's evrey thing is winding down. So how could rna turn into dna if evreything is winding down?
Not interesting.
Come back when someone has an idea of how the backbone would have fused naturally which is required for actual RNA replication. That's the biggest contention of the idea that RNA is the beginning of life since without it, there is no self replication.
Stupid fucks dont know how pyramids were built. Yet claim to know such much more. Lmao
Your to cringy please stop and go back to the kitchen
religious people: Autistic screeching
Here for the triggered comments lol
could , might , may ..are not scientific words .Science is evidence not a theory that could not be tested and reproduced .so u re busted ??
Fire this lady her personality doesn’t promote learning. ?
Blind atheists smh
Or we may NOT
It’s very simple people God
I bet they had big oof moments. Lokey
Clickbait
All is guided by consciousness.
Let's get this figured out so the Creationists will shut up.
Why does every YouTube personality have to sound like an uppity, cheesy paid actor
You sound sick girl ??
Evolution is bullshit, heliocentrism is bullshit, the big bang is bullshit. And you're a fucking idiot
Somebody just basacly made a new world duh
Nothing like the realization that someone said to themselves, “make sure that those hands holding signs at 2:05 into the video are multi-cultured;” we don’t need people on the internet shitting all over the fact we made all the sign holders white!
Life is inevitable. Patterns that replicate will continue to persist, and more successful replicating patterns will proliferate. Life is the preservation of information via transmission through replication.
This experiment ran decades ago though….
The whole video is just beating around the bush. No scientist has then answer to this question.
A 4th believes that there's a creator..
creationists [*]
Allah is the one who created the earth and created Adam an Hawa that’s how life started
Only if your a Muslim you will understand
Another desperate salad of bullsh¡t! Any phenomena related to spontaneous life must be repeatible and consistent with known physics.
Hi Nerd Girl…what’s ur name…
It's obviously God. Right?
Someone help her find her way back to the kitchen.
First I like to say that I actually appreciate that the Verge is taking the time to show these Videos so everyone else can either look into this more and open up everyone's mind and thoughts to learn and research more on their own.Thanks so much for sharing Deb ??✌
How does this relate to the Miller/Urey experiment?
…….God.
one definite answer: ALLAH created everything!
Adam and Eve came first
Keyword: May
Does that mean the short answer is causality?
The images of the proteins on an atomic scale are awesome. There’s also the “flip it” program for eye candy.
Even if the RNA acids were to assemble, that's still a VERY far cry to developing into even the most basic organism.
I do not know your name, but I like all of your posts or reports on Seeker. I appreciate the science news, and the facts. It is easy for me to listen to on my breaks.
This video gives no answer, just the knowledge of 50 years back. Stupid Clickbaiting.
So what actually god did?
Please note: the Dev newman structure; (revised version of the vannewman structure in computing)
Life is a reciprocal function of death
Life is inversely proportional to your situation
Your situation is directly proportional to death
Death is directly proportional to life
A situation is the result of a set of protocols
Protocols that were applied by humans
A Protocol is a set of instructions.
An Instruction is a set of commands.
A Command is an action.
Actions that were taken by humans involved in your situation.
decrypt your situation to get information.
Set your information as the protocol.
Apply data already known for this protocol ( data aka knowledge)
Then send the commands into your situation via your medium or interface. ( aka "speak" or txt). Repeat.
It's for you to applied the math, world, i was always bad at it, but at least give me the credit if ever you use my code.?
The clickbait title does not get unlocked in this video.
The Miller-Urey experiment was completed and published in the 1950s, dude.
YOU NEED JESUS IN YOUR LIFE!
Lost at DNA
Bullshit this one , you show I love this "theory" is not near a good probable answer.
When these Christian niggas say everything is responsible of god but realise all the diseases and shit going around in Asian and African countries and then have to blame it on lucifer.
Irritating background muzak

3:07 missed the chance to spell GUAC but okay
So life on other planets with those elements in a flux state, energetic enough to form RNA strands is highly possible?…
Hate this smug bitch
All the elements needed for life aligned and our adaptation to the enviroment (substinence) shaped mutation thus evolution.They ask what came first the chicken or the egg? Neither,the yolk came first.We are much diffrent from our roots.
Here's a Paradox: How was Time Itself Created?
If you read the Qur'an you'll find the answer your looking for go and read you don't know anything but Allah does because Allah created us and knows everything ❤
We were made by God there is no possible way we were made from a big bang or a chemical mix
I see where your going but there no need in lying and making it longer just accept him accept christ who loves all
Prometheus told me how….
Some day a sentient "Computer" will argue where his/her/it's building blocks came from.
Sure there is metabolism with Chemistry before life it a question of trial and error of nature the first scientist is the nature, that is why math fits so well with science, math was also invented by nature humans just rediscover it.
Until all the planets were aligned as in the Eclipse that you narrated of Einstein, and there life arose. https://www.cam.ac.uk/research/news/metabolism-may-have-started-in-our-early-oceans-before-the-origin-of-life
I think that from a percentage or perspective everything is alive, it is that there are simply different metabolic processes and at certain times you can say that there is life, happiness and heart metabolism are intertwined and require interdependence, but metabolism alone does not make you human, the positive of the human being, his spirit his heart, that part is still a mystery to me, I think there must be a god, an angel
I think that since this ABBA theme is an angel like you, metabolism has a lot to do with genetics, but also intuitively and because of its content there is something artistic that comes from inside the soul, having children is the answer of having real happiness to be able to survive the heart that one carries inside with posterity https://www.youtube.com/watch?v=zxgQGw8v59E
