Harrot Posted October 7 Share Posted October 7 In the past, I was like everyone else, trying to figure out how to define things like life, intelligence, freedom and so on. Today, I know the answer with certainty. The principle is as follows: If there's a word whose meaning everyone knows, but there's no definition other than: I define it this way because at least we need a common definition, but there's no real reason to admit it, then... there's a high probability that the word belongs to the category of words related to feeling. We feel life, so we have a word for that kind of feeling: alive. So “alive” is nothing other than that....a feeling. “And what about the concept of 'truly' alive? “I reply: “The what? It would be a very big coincidence if, for a word that comes from a feeling we have using our naked eyes (because yes, the word life is an old word), thus an erroneous conception of the living things around us, there was also a real concept behind what would exist in the world. Other misconceptions include “animals”, a kind of animate living beings, but of course this isn't always the case. After classifying living beings (yes, we can! Arbitrary classification works well in some cases and for some reasons), some scientists thought they could distinguish those that are “animate”, i.e. “in motion”, from the others. But we now know that there are species that contradict this rule. Some animals don't move, and some non-animals do. The reasoning above can be applied to many other notions. I particularly like it when it comes to defining the term “random”, leading to the conclusion that random is very likely a feary tale. Now that we know (or at least it's very likely) that “life” is just a feeling, we can of course try to find out why we feel that way. After all, the thing we have in front of us “looks” like life, and yes, the way nature created it is not the same as the way we would use if we wanted to manufacture it in a factory. Therefore, “what looks alive” and “what is created by nature” have something in common, of course, at least because the “mechanics” have the same origin for all the “living” things nature has created. Are viruses alive? No more or less than a cell, but because they come from cells (yes, cells create them), they can be considered to have the same origin as life: created by nature and related to things we consider living because that's how we feel about them. They are related to life forms and we can even speculate (I had a teacher who believed this) that they are a kind of “spore”. Are mushroom spores alive? Yes, no, but they obviously come from living cells... that's just my feeling on the subject. Link to comment Share on other sites More sharing options...

There is mounting evidence that the conditions required to make it happen were exceptional. And not wanting to upset Zapatos again, but we still have not figured out how to do it. I think the trend is more in the other direction. As time goes by, it becomes more and more likely that life could be a very common phenomenon, but of course nothing is proven. The discovery of probiotic molecules already formed in space, for example, is a point that has changed our opinion on the probability of the appearance of life. Quote In the past decade, it has become clear that the interstellar medium (ISM) is an extraordinary chemical factory. About 250 molecules, including ringed-molecules (see e.g., Cernicharo et al., 2021; McGuire et al., 2021), have so far been reported in the ISM. In addition, the pace at which new molecules are detected not only seems steady but accelerating (McGuire, 2021). In particular, the so-called complex organic molecules (or COMs)1 have attracted great interest in recent years since a subset of them could have been involved in the first biochemical reactions leading to the origin of life. This sub-set of COMs are typically called prebiotic. Some examples of prebiotic COMs include urea and hydroxylamine (Belloche et al., 2019; Jiménez-Serra et al., 2020; Rivilla et al., 2020) since they are possible precursors of ribonucleotides (see e.g., Becker et al., 2019; Menor Salvan et al., 2020); ethanolamine and n-propanol because they could have triggered the formation of phospholipids (Jiménez-Serra et al., 2022; Rivilla et al., 2021); or amino acetonitrile, vynil amine and ethyl amine since they are considered precursors of amino acids (Belloche et al., 2008; Zeng et al., 2021). One of the most extended theories about the origin of life is the primordial RNA world. In this scenario, early forms of life relied solely on RNA to store genetic information and to catalyze chemical reactions. The basic units of RNA are ribonucleotides, which are composed of a phosphate group, a nitrogenous base, and a ribose sugar (a C5 sugar with five carbon atoms). Interestingly, only small precursors of sugars such as glycolonitrile (HOCH2CN; see Patel et al., 2015) or the simplest C2 sugar molecule, glycolaldehyde (CH2OHCHO), have been reported in the ISM (Hollis et al., 2000; Beltrán et al., 2009; Jørgensen et al., 2012; Zeng et al., 2019). Indeed, searches of C3 sugars such as glyceraldehyde (CHOCHOHCH2OH) or dihydroxyacetone (DHA, with the chemical formula CH2OHCOCH2OH), have not yielded any robust detection (Hollis et al., 2004; Widicus Weaver and Blake, 2005; Apponi et al., 2006; Jiménez-Serra et al., 2020). In contrast, larger sugar-like species such as C3 sugars and ribose have been found in meteorites (de Marcellus et al., 2015; Furukawa et al., 2019), which opens the possibility that these species form in interstellar space. https://www.frontiersin.org/journals/astronomy-and-space-sciences/articles/10.3389/fspas.2022.843766/full Of course, not all environmental conditions apply, but some scientists now believe that we may have over-restricted the requirements for life to appear and that the Earth model may be just one of the possibilities, arguing that if extremophilic species exist, life could be more diverse than we think. Quote Providing Clues About Possible Life in Space Since hyperextremophiles inhabit conditions that are inhospitable to most life, they have been considered as models for extraterrestrial life. Researchers have been investigating the microbial life of sites like the Yellowstone National Park, Antarctica and the Dead Sea to isolate them. For example, a strain of the archaeon Methanopyrus, isolated from a “black smoker” hydrothermal vent grows at temperatures of 120℃, while another microbe Picrophilus can be present in conditions where the pH is as low as 0.06, such as solfataric lakes in Japan from where it was isolated. Such microbes could hold clues to understanding how life might potentially survive in other planets. Very recently, researchers discovered traces of life in geological samples in the Atacama Desert in Chile. These samples, known as the “Red Stone,” contained hematite and were geologically analogous to Martian soil. Interestingly, none of the life forms discovered could be properly classified phylogenetically. Researchers conclude that looking at extremophiles on Earth could give a better clue for addressing whether similar life existed some time ago on Mars and other planets. https://asm.org/articles/2023/march/how-extremophiles-push-the-limits-of-life Some even think that life could be the standard fate of molecules when placed in a particular type of environment: As with life forms, there could be a Darwinian process using trial and selection of the arrangement of molecules. Quote England is suggesting that biology arises because, in certain environments – like on planets – where the energy balance is so out of whack, physics guarantees that atoms rearrange themselves to be able to deal with the chaotic flow of energy. These atomic structures just happen to resemble what we refer to as “life”. As England famously said back in 2014: “You start with a random clump of atoms, and if you shine light on it for long enough, it should not be so surprising that you get a plant.” Using cutting-edge computer simulations, England and his colleagues dumped basic chemical compounds into an early-Earth like environment and watched what happened. The first paper, in the Proceedings of the National Academy of Sciences, shows that life-like structural arrangements of atoms spontaneously arise. Importantly, biological inputs and variables – the behavior of cells, the formation of DNA, and so on – weren’t preprogrammed into the simulations. The second, published in Physics Review Letters, shows that when driven by an external energy source – the Sun, in this case – these atoms rearrange themselves in order to absorb and emit the energy more efficiently. Perhaps most remarkably, these life-like structures started to copy themselves in order to better handle this energy flow. https://www.iflscience.com/life-inevitable-consequence-physics-43007 Link to comment Share on other sites More sharing options...

So far as I am aware all life, with the exception of an amoeba dies. An amoeba can be killed, but that is a different matter. Dying has no meaning for an organism that reproduces by splitting as it does. In one of your threads, someone responded that Life is not a thing or a property but a process. And processes need a suitable host system. I think it is worthwhile examining the subject of life (and death) in terms of this idea as it not only allows for living and non living parts of the same system, does not imbue things like water molecules with life in their own right; it takes us beyond the current biological restrictions I posted earlier and I think are too narrow. In doing all this it offers somwhere to place this mysterious 'spark' you claim is non religious (so do I) as well as offering a platform to examine what happens as the process degrades and even fails. Yes indeed there is much to be learned. Link to comment Share on other sites More sharing options...
