But what youre not realizing is the only reason crystals don’t ‘evolve’ is because youre looking at the wrong timescale. Atoms truly are the entire universe, and have tried everything they can - such as making bacteria
Right, except atoms are not self-replicating, thus while they try out many possibilities (or you could go deeper, quarks or maybe strings, or whatever), they have no “memory” of past states, thus cannot be said to truly “evolve”. An atom that was in a molecule and then leaves it, if queried even a femtosecond later has no idea that it was ever not in its current state. Therefore it has no genetic identity that can be acted upon to change, thus an atom cannot be considered an actor, only a thing that is acted upon. Truly I did think about simulations using atoms, it is just that those studies, while not useless, are not studies involving evolution.
Population studies at minimum require a kind of genetic identity that can be altered in response to circumstances - e.g. a classic example is birds that are darker in color becoming more predominant in a UK town after an industrial plant belched smoke into the environment (I think that might have been discredited, but for our hypothetical purposes it works as a handy illustration:-).
And actually, crystals meet that minimum criteria, bc their leading edge of growth can be acted upon to go one way or another, not just bc it has atoms but bc it has an arrangement of those that does. Although crystals looking one way or looking another way, on Earth at least, given weather effects and such, does not tend to go beyond very simple patterns. Now on Pluto, if the same crystal can itself last millions of years, then yes it’s possible that it could do more. It’s hard to go beyond the hypothetical there though, bc it’s so far away, and also there are places on earth (bottom of the ocean mainly, but also deep beneath the crust) that are even harder to get to with current technology, so if we would bother to care about exploration then maybe we’ll find out? But unless a trillionaire decides that they are interested, I doubt it in the short term.
Whereas bacteria we know that for CERTAIN, and we’ve even made use of that in our biotech for like 60+ years - e.g. using bacteria to make human insulin - or with less precision tools possibly thousands of years e.g. stories of sages like Arthurian’s Merlin using “healing powers” (possibly fungus containing the very same antibiotics that we now artificially manufacture?).
Ah but simple hydrogen atoms you might be right, what about helium and higher?? You can recognize their identity, and they were not initially there - a time dependent (and repeatable) process made them.
But I suppose I disagree evolution requires a genetic identity, as that is by definition biological, and so yeah atoms ain’t gonna make that criteria
(but atoms did make the cells that rearrange the atoms, sure a hell of a lot more randomness, but they took the time to get there - evolution without direction esque)
You seem to be thinking of something else where the word “evolution” does not readily apply. That word generally means a gradual change, in particular in response to environmental triggers, mostly in biology yeah but not exclusively - like political thinking “evolves” over time. Atoms gaining/losing electrons or even protons/neutrons is rather sudden, and while I suppose you could model the total number of subatomic particles in a system and use the atomic configurations they are in as the “identity” state that “changes” over time, or in response to variations in a star let’s say, or even more loosely the amount of time that they bother to form atoms at all in such a plasma state, but I have never heard it used that way.
Maybe an example is how a computer is not only made up of 0s and 1s, but a system that makes use of those 0s and 1s to accomplish tasks, so that it is not merely flipping bits for their own sake, but instead, changing the bits alters the actual “information” content present in that system. It is the information itself then that evolves, not merely the bits, nor the electrons that make them up. In contrast, if an animal grabs ahold of a computer’s hard drive, it may nibble on it, bat it around, try to mate with it, use it for nesting material, etc., but absent the computer itself, the patterns of 0s and 1s and electrons and such is no longer relevant. Hence even if it changes e.g. gets erased, or constantly gets modified by irradiation or whatever, I think we would no longer call that “evolution”, even though it is still “change”. Ideas likewise can evolve bc we humans will adapt our actions based off of those thoughts, so the patterns are still part of an “information” system.
But subatomic particles being in an atom or not… I don’t see how that stores any “information” really, at that same level of organization. I mean it obviously does, bc everything is relevant, but what is interesting about it? Rather, atoms form the substrate building blocks upon which other forms of computation can take place, and like while biological DNA cannot store information without its component atomic structure, at the end of the day it is the “information” present in the DNA that it said to evolve, independently of its origin. Proof of that comes from us now being able to synthesize completely artificial DNA from scratch, using whatever code we input into it - so despite having no physical connection whatsoever to the original, a genetic message can be replicated, with or without modification. “Descent with modification” can now happen to messages that once were purely biological (as far as we knew, absent any aliens that originally made it or our computations all being a simulation in The Matrix or some such:-) but now can go through a virtual phase.
In contrast, while atomic structure certainly “changes”, I am not aware of any information processing systems that really make use of that fact, beyond the obvious “atom A is over here and like this, while atom B is over there and looks like that”. Then again, who knows really!? Anything is possible!! As the quote from Chrono Trigger says:
Am I a butterfly dreaming I’m a man… Or a bowling ball dreaming I’m a plate of sashimi? Never assume that what you see and feel is real!
Bc physics basically, particularly the principle of conservation of mass, but more to the point I suppose, if that ever does happen, then I simply am unaware of it!:-P
What makes crystals self-replicating is not that they spontaneously appear from thin air (although it could appear that way sometimes?) but that as they grow outward in one direction, new atoms attach onto the preexisting pattern, so the overall mass remains constant, and overall entropy still increases (though not locally), but the “pattern” is what gets replicated.
With that in mind, molecular prions such as mad cow disease/scrappy can self-replicate in a limited sense where when the disease-causing form comes into contact with the natural form, the former converts the latter into becoming like it. Here too mass is conserved, but the pattern has been changed, acting as a propagation of a signal (“be like me”, I guess?:-P but like, literally the situation would change from one molecule of each type to two molecules of a particular form, so the information content of the system has changed).
Perhaps a similar process can happen to atoms, although nothing really comes to mind in the sense of a population. Like water isn’t H2O so much as a collection of H3O+ & HO-, and I can envision them converting forms constantly shifting the electron around, but (1) the overall population of the body of water would not be changed then, and (2) I think I’ve heard that even that much may not be quite true, probably depending on how pure the water is?
But really it’s hard to see how any of the above can be called “evolution”, except in like a low-level technical sense that offers far less of interest to study and think about… at least, as clarified above, on earth and on human timescales.
And I mentioned that viruses self-replicate as well. Those at least are more interesting bc of the genetic component, even if they may not be free living and thus fully “alive” depending on how you define that.
There is little that is ever “fully true” in biology, only a massive collection of rules, almost every single one of which has exceptions it would seem (like I could imagine saying “all known life is found exclusively on earth”, and then wouldn’t you know it, someone will eventually discover that bacterial spores can be found in space as far away as Pluto, just waiting to become rehydrated and come alive again:-D). So when I say that bacteria are basically the smallest unit of evolution, I already know that’s not “fully” true, just that it is one of the most “interesting” forms. Crystals, molecules, and atoms don’t sprout a tail and swim towards the light at least, or there too if they ever have, then I did not know about it!:-D
