Where Did Life Come From? (feat. PBS Space Time and Eons!)

[@besmart]

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.

Precision medicine, Spacetravel, Artificial Intelligence, Nanobots or just good old curing cancer and aging. A well-paid job is guaranteed.

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.

[@evrimagaci]

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.

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.

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?

[@DanielWilianto]

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?

[@suelane3628]

@@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!

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.

[@k_schreibz]

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.

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: kzbin.info/www/bejne/mqbOnIJtmJeYi6c.

[@therealpa3ng]

2 issues I have with RNA world #1 - The building blocks that make up RNA are difficult to synthesize and are easy to destroy. RNA is composed of 4 nucleotide bases (adenine, cytosine, guanine, and uracil), phosphate molecules, and ribose (a sugar). However, it is difficult to form and maintain these components simultaneously. Not only are nucleotide bases inherently difficult to synthesize, but they are also unstable at temperatures similar to those of the early stages of the earth when life began to develop. For example, at 100 degrees Celsius, cytosine only has a half-life of 19 days; this is far too short a time period for the first functional RNA molecules to have developed through chance alone. Another issue is that scientists speculate that ribose first formed due to the “formose reaction,” which involves the formation of sugars (including ribose) from formaldehyde. However, this process is inhibited in the presence of nitrogenous molecules... which include both amino acids and nucleotide bases. Both nucleotide bases and ribose are required for the formation of RNA, and yet, it appears as though the chemical conditions that make the formation of nucleotides more likely are "sharply incompatible" with those conditions proposed for the formation of ribose. #2 - It does not explain the origin of genetic information The information capacity necessary to randomly synthesize even one protein of modest length is already astronomical... to speak nothing of the full range of proteins necessary for life. Neither can we appeal to self-organization, because as with DNA, there are no bond affinities that can account for the specific sequence of the nucleotide bases within RNA. Though RNA theoretically has all the properties required of a molecule that could catalyze its own synthesis, self-replicating systems of RNA molecules have not actually been found in nature. Scientists have engineered partial replicators, but in order for these to have formed by chance in a primordial soup (and later evolved into DNA and proteins), one would need a specific sequence of around 200 nucleotide bases. The odds of an RNA molecule randomly forming into functional RNA that could self-replicate are astronomical... In fact, if one considers all of the seconds that have passed since the beginning of the universe, there still would not have been sufficient enough time to have formed even a single, functionally self-replicating RNA molecule.

Thank you very much. Heard Dr. Tour say much the same things. Cool little youtube videos are counting on people not knowing any of this so they can all be amazed at how scientists have it all figured out--except for the fact that they don't.

[@Quell__]

@Brix Anchor its easier to believe in something that doesn't exist than to face our (subjectively random) harsh and brutal world. How else can we justify all the bad things happening around us? Religion gives us hope and a reason as to why we exist and why we experience traumatizing events. From an evolutionary stand point, religion is a genius way to make us feel life worth like living through. I bet the earliest species of humans killed themselves a lot back then. No hope is truly the worst for an intelligent consciousness. Have you noticed the trend of people becoming less religious every year and the trend of people dealing with less traumatizing events in their life time? We have No need to hunt, kill, fight and run for our lives anymore. What a coincidence that less people get religious every year... It's almost as if our environment is not brutal enough to get an explanation or hope. Maybe one day religious fanatics rule the world again and make the world a worse place to live in. That would skyrocket religion adaption rates.
