The origin of life is one of the most important mysteries in all of science. When did life begin? How did life first evolve from chemistry? Where did life get started? In some primordial soup or somewhere else? Let’s journey back to the origin of life, as best as we know it, from the RNA world do the last universal common ancestor of everything alive today.

The origin of life… it's a big question. Maybe the biggest.
Head to PBS Space Time and Eons and watch the rest of this collab!
Okay, there is something I never understood about this theory: Why did it only happened once? There are hydrothermal vents in the oceans today and they have been around eversince the begining, yet we don't see random living molecules pop into existence. Is it because: A. Life was a one time accident. B. Life did not start there. C. The vents didn't know enough about the Dark Side to create more life. D. I don't know what I'm talking about.
@Daniel Bojtor: How about, it may have happend any number of times but only one of those ultimately resulted in all the life that we know, since the moment that 'Life' has a foothold it will consume such molecules that could have made new and different life and by that time 'Life' has a big headstart on any upstarts coming later.
I have an idea for another video. What would happen when two black holes come within range of eachother?
In the description: "from the RNA world do the last universal common ancestor"
Pretty sure you meant to write "to" instead of "do".

I was not only surprised, but deeply gratified with the content of this video. As a long-time watcher of science and science news, and an academic who followed the fortunes and misfortunes of the philosophy of science, I found myself deeply engaged in a play by play story of the beginning of life far more plausible than those preceding it. The cooperation with Eons and Space Time was well done. This trio of PBS channels has outdone themselves recently with well-done documentary and explanatory work. I know this show is a bit older, but it encapsulates a wide variety of issues at the forefront of scientific discovery. Kudos to these producers.

I always LOVED the struggle against entropy definition of life. Not just for living things, but for MY life in general, and seemingly, most other peoples' lives as well. It feels like we're always struggling against that entropy to put more order into our lives, to build them up from the ground (usually?) and to make them into something considered useful or successful, depending on your goal. Of course these are generalizations. Your mileage may vary. =P
It's so cool that such a notion applies to different levels of analysis!
Entropy should be seen as motion.
@@waldwassermann Why?
@@waldwassermann : Everything is in motion. Entropy is increasing disorder.
the effects of civilization to evolution is a very interesting subject
This video was pretty good but in multiple places it is said that life is a "closed system". In fact, the opposite is true: Living things are definitely open systems (thermodynamically speaking) and they would not be able to stay alive if they were not. I think what you meant to say is "enclosed systems" or some sort of "enveloped systems", i.e. they have a boundary between the interior and the exterior of the cell. We like to call them "organization", since it is this very feature gives the general shape of the organisms.
And it makes a clear distinction too: Viruses aren't alive because they have organization ("enveloped system") outside the host cell but they do not have the machinery, or "activity" to sustain their order. The moment they find a host cell, they somewhat gain this activity by stealing the machinery of the cells they infect - but this time they lost all of their "organization". So life requires "activity" (to sustain order, i.e. "metabolism") and "organization" together to create life.
Watch the companion pbs space time video, life from a thermodynamic perspective in discussed in detail over there.

As a student of bioinformatics I must say:
Probably one of the best videos on this topic. There is way to much old or misinformation on the internet, it's actually quite infuriating.
Thanks for this vid guys!
Chribit I’m thinking of taking bioinformatics as my major, is it worth it?
Lord Murphy
100%. you probably hear this about any course, but bioinformatics is one of if not the best choice regarding the future. With a degree in bioinformatics you get the tools to advance into any other scientific branch.
you'll be the link between biology and computers... and that is useful for basically anything anticipated in the next decades. Precision medicine, Spacetravel, Artificial Intelligence, Nanobots or just good old curing cancer and aging. A well-paid job is guaranteed.
So yes. 100% worth it. do it. help change the world to the better.
Too*
Lord Murphy he's a student. He can't answer that yet. ;)
I can though ^^ just because I haven't finished learning, doesn't mean I don't know what opportunities i'll have. If you read enough non-fictional books concerned with our future, you'll notice that most of them contain some form of area bioinformatics will be insanely useful for. So yes, bioinformatics is / will be (for me) worth it.
I haven't met anyone who has said otherwise, btw. I'm not just talking about actual bioinformatics-professors. Most of the professors in the fields of biology, chemistry and informatics know the value of this rather new degree course too.

I think the reason why the question of where life came from is so complex is because we're foolishly looking for one solution when there are probably multiple solutions that all helped get us where we are.
No. Only one according to infinite regress or reverse reasoning.
@@waldwassermann Which is why we will never find the answer, there isn't just one correct answer.

"Life isn't a thing that things have, life is what living things do." @DrJoeHanson, may you be quoted for that phrase, or was it borrowed from another source?
That's all me! (as far as I know)
The closest thing that I have in mind is Carl Roger, but it concerns psychology. "Life is a process, not a state of being". In all honesty, that's about 'good life' rather than life in general, but this distinction between process and state has been floating around for some time.

“Must work to avoid decay” so people who gave up are already dead.... depressing...
Use it or lose it
Actually, it is the germ line which survives. Every single living thing alive can directly trace it's germ line to our Last Universal Common Ancestor. That is what I call 'One finger up to Entropy.'
As something that is so elegant and understandable as this, why do so many people refuse to understand it?
Because many of us were taught that life begets life and that's not likely to change until it can be clearly demonstrated how non-living material will self-assemble into a biological organism.
If you believe all of this, then can you please explain it to me how a computer came to be a computer? Even if i say given as much as time as the age of the earth. Would you ever gonna have a comouter who has a cpu that knows how to compute own its own from the start, a cpu fan to keep it cool so that it doesnt over heat, a gpu that output anf compute graphics to help display its enviroment, a motherboard for the setup and everything, some rams to help and compensate its computation, and even has a case for protection when it doesnt know whats coming such the existence of weather like rain and etc? Not to mentiona comouter own its doesnt even know what to do from the start, it cant even do 1x1 until someone created it and programmed it to do so or even anything that its capable of today, so you can find all of these material like the metal or copper that was used to build the sam comouter, but does it mean the comouter came to be what it is by chance, F NO!!!! NEVER!!!! NO for all externity, NO for sure if you brains.
Henry Bones with all the intermediate advanced grammar you’re using it seems you’re giving of the im smart vibe so if ur that smarty answer ur own question
Understanding is not something one can refuse, it is grown from facts, and thinking to become knowledge and integrated into other knowledge to become an understanding or in the Latin a standing in the midst of (facts and knowledge.) If people don't understand something it's because there isn't a group of facts and knowledge to stand in the midst of or it hasn't been portrayed with skill and effectiveness. Making a glamor to give the impression of life from non life doesn't provide the substance of life from non life. If you simply asked for evidence of real life from non life before accepting it as fact you would be with those who think for themselves and hold to the facts. Cheers. Sincerely David
If it is so easy and simple, can you tell us why so far zero scientists have managed to make life from non-life and I'll bet you that will not chance any time soon. If you think the video explained how life automatically comes to exist from non-life I think you didn't understand the video that well.
This was awesome. Thank you to everyone at It's OK to Be Smart!
Quick suggestion: please make sure your presenters are not speaking at a comprehensible speed. The second gentleman spoke very quickly, so I missed a lot of what he said. I will go back to rewatch and turn the playback speed to 0.80 though just because this episode was so good.
This was awesome! Thanks!
Thanks!!! As a biology teacher, this is one of the best videos about the origin of life I've seen!
I'm posting it to my students right now!
Luis Peña As a biology teacher, are you going to let the students know that they don’t actually answer the question? Instead of tackling the problem of how DNA needs proteins and proteins need DNA he decides to just say “maybe RNA did it” without talking about the impossibility of RNA just popping into existence spontaneously.
This is what’s wrong with the “science education” community. Just throwing out an unverified unprovable theory and acting as though it’s fact. I seem to remember that the scientific process involved being able to reproduce results and prove things by experiments.
Why? So they will learn that PBS doesn't know how life began either? How is this video educational it answers no questions and when it comes to hard fundamental problems he just skips them.
Luis Peña Hello. I was just watching this video. I saw a lecture by Dr James Tour at Waterloo University. It is on UA-cam. I think you will find it very interesting. It is 1 hour 23 minutes long. If you have time, I'd watch it. Si
@@russianbot8423 why? because maybe, some youngsters not influenced by idiotic religions, can answer those questions in the future. not all is known. instead of going the dead end way of explaining unanswered questions with something stupidly simple like "reliogion" I rather have unanswered questions. because: SCIENCE

Your belief in science hinges on fantasy and requires complete blind faith in a CHAOTIC UNIVERSE in order to explain an ORGANIZED UNIVERSE. God is just to easy an answer for you Soo you choose to 'Believe' in indefinite irrational contrarian conjecture and proclaim your tomes of defeated and naive notions and unborn theories to be your own God. You are a stuborn fool blinded by emotion and anger. I hope nothing happens when you die.

It’s called deaf school dummy
In other words, once molecule(s) could copy-paste itself, life began.
@May Ling isnt that copy-paste?
You're right, the fact that some molecules self-replicate is the reason life is inevitable. May Ling is talking about cellular life. You are talking about life more generally, and you are correct.
@@crowmollymedia6480
Glad someone get it.
I think its more kinda like, copy -> edit -> paste
@@niko-ni6ps the editing happen when sexual reproduction happen. Back then, its only about making copies.
the effort to make it so interesting is appreciable!
It’s easy to make it look interesting when you’re basically writing your own science. Remember that none of these smart guys were there when a man took his first step. The evidence in the fossil record shows that all life came into being about the same time, with no signs of pre-evolutionary forms.
The scientific method requires observation before something becomes a fact! Otherwise we are just interpreting the evidence to fit our best guess. It’s called controlling the narrative.
At the end of this, you ask why life started, and suggest that it isn't a question for scientists. But Matt O'Dowd offered an answer within this video that perhaps you didn't catch -- life is inevitable because although individual life forms preserve order within themselves, they can only do so by being even better at increasing the entropy around them.
Close but no cigar.
Ight so my oldest ancestor was made in a hot lake? Cool
chilling with hot hydrogen bubbles. Even it got more action than me
Wait.... Are you cat giorno?!
We have no idea how life exactly came about.
The building blocks of life as we know it are chemicals called amino acids. We know that they can form naturally, in lightning strikes and other energetic phenomena. But how did we get from amino acids to RNA, the fundamental unit of advanced life, is a complete mystery. How many times did that happen independently? Once? A zillion times? We don't know because we have no idea what the mechanism is.
Some people argue that it happened so rapidly on Earth, that the probability must be high. Therefore, there must be abundant life near other stars. But we really don't know. It is conceivable that the probability is so tiny, that if you plug it into Drake's equation you find that we expect life to have formed only once in the entire universe.
My own guess (and this is not a scientific theory) is that there was a precursor form of living molecule that was capable of carrying limited genetic information, much less than RNA, and still capable of reproducing. When RNA developed, the more primitive form of life could not compete, and was literally eaten up.
There is a science fiction story that illustrates this. A group of advanced computers rules the world. One little baby computer asks, "How did computers come to being?"
The mommy computer answers, "We don't really know. We can trace our beginnings back to a microprocessor that was first created in what we call year zero" [in human years, this corresponds to the late 1900s, but mommy computer doesn't know that], "but we can't conceive how that first microprocessor was created. It's too complex to have come about by chance. Maybe there was a primitive life form that preceded it, and which is now completely wiped out. Carbon is on the same part of the periodic table as Silicon, so some people think it might have been a carbon-based life form. But carbon doesn't make very good electronic circuits, so I think this idea is foolish."
Brilliant :)
The amazing thing is 4 of those amino acids link up in many ways to create the real life, that is all. I saw an article where they tried to insert additional amino acids into the chain and found one other but it had to engineered to work, so 4 is all there is out of 22 amino acids. There could have been 0 or 2 amino acids that were compatible, both which might not be enough for complex programming of life. The periodic table and how thinks link up is another amazing thing that is needed for what we see around us, that probably could be different and break everything. The quantum parameters could be slightly different, which again would mess things up. If you are looking for evidence of some outside force manipulating things, science and how minor variations and just the right balance of things would be a logical starting point instead of fiction written by people with little understanding of how things work.
@@mykofreder1682 what fiction and people that don't know stuff are you referring to? In fact synthetic dna has been created in the lab successfully, it has an extra two amino acids, they named them x and y, so instead of the usual atgc this new one has atgcxy. They needed to use bits of an already existing cell to create the viable synthetic cell.
@@mykofreder1682 they successfully added two making a synthetic form of life with 6 letters of dna code
If the building blocks of life were around and time shuffled them over & over for basically an eternity with trillions of planets; odds say random chance will eventually come up 7 or 11!

Not a bad beginning but like you said there are a lot gaps to fill. But this is the most sensible and honest discussion I have heard anywhere. It only seems unlikely with the age of the universe and the even shorter age of earth that there is only a small window when life might have had the right conditions to start.

Holy crap... the more I hear about Darwin, the more I appreciate his genius. It amazes me how he had such a clear understanding of life that many of his insights have been proven in one way or the other 200 years later. Truly someone I admire greatly!

He wasn’t the 1st or only person, many other biologists came to the same conclusion around his time.
Charles Darwin did not invent the concept of evolution.
Life is less of an object but an event, a process.
Indeed all in our Universe is events, patterns in the greater Space-Time 4D object that *is* reality. We can only see these patterns in 3D as we are result of these 4D patterns ourselves we see cross-sections of reality, but not the whole thing. That is the illusion of "Time".
Bonus: We don't even see the whole of our cross-sections unfortunately, considering it takes "time" for our brains to process what we see there are tons of things much faster than us that we miss, like lightning, watch it in slow mo, it's amazing: ua-cam.com/video/dukkO7c2eUE/v-deo.html. And on the other end of the spectrum we are too fast for things like the evolution of giant space objects like our Earth and it's continents.
Cool, thank you!
"Life is just a thing that happens," may be the best explanation for life I've ever heard.
"life is meaningless"

The most important step (from organic molecules to self-replicating RNA) still seems to be completely in the dark. It might have happened near that underwater vents, sure, but how you get from Micelles and energy to RNA hasn't been touched on at all in this video.
I mean, it's a great video and explains a lot, so I don't want to criticize the video per se but it makes it seem as if we basically know the main steps, which doesn't seem true at all.
Also why isn't Abiogenesis happening right now? Or is it?
Well he said that basic amino acid can stick together when bumped into each other. So they can result in a string. But there's still important question? Why would this string replicate itself?
Hi, I would highly recommend Nick Lane's book 'The Vital Question.' If you haven't time to read that, I would recommend the first chapter of his book 'Life Ascending.'

@@DanielWilianto Hi, I will give you a reply. The answer is that the 'string' of amino acids doesn't replicate. However a 50 base long 'string' of RNA does. In fact, so much so, that in the laboratory these are known as Spiegelman Monsters. The fact that RNA replicates, edits itself, carries the genetic code and can act as an enzyme; led to the RNA World Hypothesis. Different combinations of RNA bases also have a natural affinity with specific amino acids. I hope this helps!
@@suelane3628 I look it up and.. it's fascinating. Does this mean an RNA string is the most basic living being?
Thank you so much for uploading this video. It is helping me get through the pandemic!
I love this video! So informative and easy to understand.
The ingredients are Sugar,spice and everything nice.

Nah, that's just the ingredients for little girls. 😄 What about about rest of existence? 😄
One of the interesting theories is that life arose from entrophic tendencies, the need to disperse energy by building organized structures that could transfer energy throughout a closed system much faster.
Yeah I've always wondered that to. People point to humans massive use of energy as unnatural, and I won't deny that it is damaging, but I do wonder if what we are doing is inevitable. The more complex we become the more efficient we become at using larger and larger sources of energy and speeding up entropy. Maybe what we do is natural, and was always going to be the outcome of life's increasing complexity.
God I love the graphics in this video! Top notch work.
This is legendary
In simplest terms I personally define life as "a looping chemical reaction". Biology is really a sub branch of chemistry.
@Shreya Yadav
Actually, chemistry is not only physics, it's 100% quantum mechanics. Since that's what governs chemical reactions.
@@lordgarion514 which we can’t figure out. We can figure out what happens FROM quantum mechanics, but we really don’t know what’s going on on a sub-elementary level
I have an even simpler definition. God created life. That's much easier to believe than life sprang up from nothing! Did DNA evolve too? I find it remarkable how people will deny the obvious just so they won't have to believe in a divine being!
@@saturn722 LOL, So saying that your God that is infinitely more complex and advanced than any living being in existence sprang up from noting is more rational? I'm sure your going to say, "but but God always existed" as you also claim something far less complex couldn't have always exist.
And yes, as any educated person who studied life at all would tell you, DNA did evolve too, from RNA.
What I find remarkable is how people with no education on a topic deny all basic facts about that topic just so they can believe in a magic man in the sky.
@@SniperScope99 quantum mechanics is just the “tip”. 😂
I’ve watched this video several times. Love it. The perfect compliment to a biology course I’m listening to from great courses. Keep up the great work!
