www.ted.com Before life existed on Earth, there was just matter, inorganic dead "stuff." How improbable is it that life arose? And -- could it use a different type of chemistry? Using an elegant definition of life (anything that can evolve), chemist Lee Cronin is exploring this question by attempting to create a fully inorganic cell using a "Lego kit" of inorganic molecules -- no carbon -- that can assemble, replicate and compete.

in 2011 the distinguished scientist predicted that in about two years they will have it all figured out... well, it's 2022, roughly 11 years later... 9 years after the self-predicted deadline... there yet? In russian language his talk qualifies as "yerunda" (baloney in some English-speaking countries). It reminds of a song by the italian singer Mina: Parole, parole, parole.

He was a man of good health that could read German, Hebrew, and some other historical languages. He explained the real reasons behind the "rules". Don't eat pork because you'll get worms. Don't covet what your neighbor has because the only way to get those items before mass manufacturing was to take it from him. Lying leads to mistrust.

​@@antonivanov1351If creationism produces no results, it is not a practical theory, and should be disregarded. Here's a tiny sample of results we have: Geochemically produced nucleotides. Geochemically produced sugars. Geochemically produced amino acids. Geochemically produced lipids. Geochmically produced ATP and ATP analogues. Various kinds of protocells with lifelike behavior, including protocells that can move up a maze towards resources. Oh, and uhh... evolvable matter. Depending on your definition, that matter might even be alive. We made self replicating RNA molecules that then proceeded to evolve, when left alone, into some 7, interdependent strains, forming an entire ecosystem. Meanwhile, creationists can't even solve the heat problem. Or even find oil! _Evolutionary_ theory, which abiogenesis depends on, can find oil and is used for just that all the time, meaning _it_ puts food on your plate.

@rkyeun The probabilities I was referring to when it comes to quantum operations is not knowing the outcome of the system. There are many possible end-scenarios for a set of particles interacting, but there is no way to know the outcome in advance, we can only surmise the probability of it coming out in a certain state. On a plank's length- There are still conceptual ideas that have dimensions smaller than a plank's length, such as the de Broglie wavelength of a macroscopic object.

The interesting question to me is "How does the universe possess such qualities?" This research is finding out what happens when you mix this and that, but I'd like to know how this happens, how these qualities exist in our universe. Where is the energy that is required for this to happen coming from? How is consciousness possible in this universe? How is thinking possible? If better thinking has evolved over time, when was the point when thinking began?

@MarkoKraguljac agreed, the use of the word "want" in reference to molecules is unfortunate. There was a talk some time ago about genes, memes, and temes that had a much better description of life: Self replecating information. (imperfect replication of information then leads to evolution). The speaker had organized it into tiers where genes (biologic entities) were the first replicator, memes (ideas) were the second, and temes (technologies) were the third. First tier could be other "hardware".

You do not need a container for something to compete, you need instability. The most stable RNA molecule would be the more fittest information carrier for example. Then when the strain of the ultimate stable RNA molecule would have been created one can then imagine that the competition amongst these strains to adapt even further stability by adding proteins, lipids and whatnot to available as a sort of skeleton to prevent the molecule from deteriorating before it could be replicated.

​@@reasonandsciencecatsboardcom All systems contain information. Let's say you have a flood break out because a natural reservoir up in a mountain eroded its way into a new valley, producing a new river flow. Let's say the flood waters are rushing towards a juncture. Down one channel, the water is destined to meet a sinkhole deep in the earth that leads to the ocean via underground pathways. Down the other is a dead-end, a valley that is surrounded on every other side by hills the water won't be able to climb over. In this scenario, there's no way for the "water circuit" to know from the get go which way down the juncture the water should keep flowing. This information can't reach it from the destinations faster than light speed according to general relativity, and in fact, we can guess it won't reach any faster than the speed of waves in the water. And as a matter of fact, the destination must first _recieve_ information, in the form of the arrival of water, in order for a signal to be sent from there back to the juncture! So what happens is, when the water collides with the walls at the end of the second channel, it builds up momentarily, (because water is still being pushed in by the juncture,) and this produces a backup, (literally water seems to go "back up" the channel. Now, no individual molecule necessarily goes far, but there is a sort of reverse wave that goes up the channel.) That backup eventually reaches the juncture, and soon after, the "circuit" of water stabilizes --- the water in the second channel ceases flowing, and the juncture largely supplies water only to the first channel. Now, should we say that some kind of river God must have broken the reservoir to create this river, simply because the entire system calculates a stable flow rate for both channels, solving a mathemagical formula in the process? No, that'd be silly, right? The fact is, information is entropy. The amount of information necessary to describe the universe is constantly growing. That's because the universe is expanding, partly, but also because individual parts of it are growing more complex. This is a derivation of basic facts of statistics and the laws of large numbers. If every possible "microstate" (a state where nothing is unknown or unspecified, aka a state that is not vaguely described, but as specific as possible,) of the universe is almost equally likely, (and while I have no idea if they are, it's safe to say that any individual state should, not knowing anything of the universe beforehand, be roughly so,) then the most likely "macrostates" will be _large._ This means more metrics would be necessary to fill out the macrostate and give us a microstate. Those metrics are information. _Information is entropy!_ For more, I suggest reading up on Shannon Information Theory.

There is a reason people doubt that black holes are well described by our current theories, its because mathematically, singularities destroy information, and that seems like it should be impossible.

Physics is an amazing field of study, but the question that drives me to belief isn't "how", but "Why?". Why do all of these constants line up to form the universe that operates and led to us?

What about viruses? Wouldn't they be the smallest evolvable unit? They don't fall within the definition of "life" because they don't have cell membranes and require the use of living cells to replicate. They are made of DNA or RNA housed inside a protein coat and they compete with other viruses and other lifeforms. Maybe you should try to spontaneously generate new viruses, though you'd need to be careful about containment to avoid an outbreak.

Although I accept it was not designed for that task.

To take a few examples from the organisms in existens, there are many self-replicating molecules but the most famous of them are DNA. However other kinds of molecules like RNA and protein can also make copies of itself and I am sure there are other molecules.

Unfortunately, the way in which this talk is presented can easily lead to fundamental misunderstanding. I presume this is the fault of those who produced the talk rather than of the speaker himself. Analysing carefully, all that Lee Cronin seems claiming is not that any other element than carbon is capable of allowing the very extensive and complex manifestations of biology that we observe, but rather that much simpler systems using other elements may prove to be evolvable.

Oh come one... When would people get a joke? :) Besides, I'm not saying that Dawkins is at a fault here. I just wanted to point out that inorganic abiogenesis is not THAT novel an idea. Regardless, the results shown in the talk are phenomenal to the advancement of the subject...

We've made autocatalytic RNA that formed an entire ecosystem of interdependent strains in its own. It's debatable whether that constitutes life, sure, but it's definitely evolvable matter lol.

@osemudiame123 you obviously didnt get the point of my comment. If i wanted to get specific i would've said that he thinks matter can replicate without nucleic acids. the point is that he thinks non organic molecules can carry replicable information and succeed in life in a stable way, which isn't true. proteins can't be made without carbon.

@jackooboy1 That is true, but life had to have originated somewhere and there is evidence it has been here on Earth for most of its existence. Life may have not originated here on Earth but wherever it did had to have allowed nucleic acids, amino acids, and lipids to come together in an aqueous solution.

We made self replicating RNA molecules that do evolve, and in fact, evolved into an entire ecosystem. What is that but "evolvable matter"?

Yet another case of Philosophy preceding Science in it's discoveries. Though this development is still very exciting because it moves the revelations of the illusion of life and of evolution (process of elimination) dictating all of existence from the realm of metaphysics and conjecture into the light of empirical fact.

Yeah we can look for "change over time," which is evolution in matter. But how do we know the difference between change that is evolution and change that isnt evolution? ALSO consider this. Evolution has no "goal." Evolution includes the survival of some properties while the elimination and change of others. So let me ask you this. How much of one thing is to survive and how much of one thing is to change for it to be considered evolution? What ratio? Evolution is just a colloquial term.

@bindlessMoredom well scientist explained that state of materials are governed by fields in the universe. So what we could touch and feel is like tip of the iceberg of existence. Water, air, rocks took their state by following laws, that's my conclusion.

@xjaskix It needs good will to understand what I am saying. It is just my opinion that science should not be a PR project. Instead of saying that molecules "want" anything they should admit (their language must reflect the fact) that they simply dont know enough about molecule interactions to authoritatively talk about it (and simplify). If they knew, protein folding for example would be solved by now. I am just asking that language (expression) should reflect facts in all scientific fields. c>
