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!

[@danbojtor]

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.

[@g.m.2427]

@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 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.

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 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

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.

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.

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."

[@michaelrichardson9458]

Brilliant :)

[@mykofreder1682]

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.

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

[@davidfenton3910]

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

[@svalkonen]

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.

In simplest terms I personally define life as "a looping chemical reaction". Biology is really a sub branch of chemistry.

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!

[@SavedFromJesus]

@@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.

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.

Even if science could create the perfect physical human body they still can't give it consciousness as we know it!

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.

I'd be curious to see an in-depth video about viruses and how they are related to these earlier stages of life. They are not defined as alive but have some of the same criteria talked about in this video. Even though they wouldn't be LUCA they still would be related and would have formed in the same environment. Wouldn't they be good specimens to look at for those basic building blocks?

[@spatrk6634]

it seems that current understanding is that virus evolved alongside early life forms. but diverged very early on to have more parasitic "life" style, so they need actual living cell to reproduce. viruses had a big part in evolution of life. because of endogenous retroviruses. they can change the DNA of the organism and that change can be inheritable.
