What is life? Are viruses alive?

December 16, 2019


So I wanted to redo this one. The original
didn’t make any sense. I’ll keep it one as “unlisted” and can be accessed from here,
link in description. But it should have been like a side notes thing. So this is that,
a more coherent form… of that entirely unqualified conjecture.
Viruses, the things that can give you a cold or herpes, are basically just some DNA or
RNA with a little something to protect them and … that’s… it. They don’t really do
anything and most of them don’t have any moving parts. They work by: if they bump into a cell
and the DNA enters, the components of the cell will produce proteins from that viral
DNA. Then those proteins will go on to form more DNA in capsules, more viruses. There’s
tons of diversity with viruses, they infect different cells in different ways and there
can be proteins and other stuff in there too in there too. But essentially viruses are
just some DNA with a little delivery mechanism. So if that’s all they are… are they alive?
What does it even mean to be alive, to be an organism? I mean, I have this idea that
I am me, I am…one thing. Even though I’m a butt load of cells.
And all organisms on the planet, us, plants, fungi, bacteria, protists, are all cells.
1 cell or lots of cells together. Except for viruses. the virus. Which is why they’re often considered
to be not really alive. If you just removed the DNA from a cell, it’s
wouldn’t be considered alive, right? But then again, none of the individual components
of the cell would really be considered alive. They can be in a shape that is unique and
assembled by living systems. But enzymes, cell membranes, ribosomes, nutrients, water.
None of the stuff that’s in there is alive either.
Life might not be a bunch of objects that you can hold like that. Maybe it’s what they
do together that makes life life? But if we look at the way each component interacts,
we wouldn’t see any phenomena that you wouldn’t be able to explain… studying physics or
chemistry. What I mean is everything going on happens predictably and just follows the
fundamental physical properties of the atoms like attraction and repulsion and different
ways of bonding. But the interesting thing taking place is,
well it’s kind of like a rube Goldberg machine. Each aspect is inanimate, but each product
of one interaction goes off and interacts with another, and another and etcetera. In
such a way that the system looks animated. But this machine isn’t alive. Where’s the
“life” happening? A rube Goldberg machine behaves with potential energy, one bit setting
off another bit. And when it’s done… it’s done, until someone puts that energy back
into it by resetting the bits. In a cell, the machine is branching and elaborate
in ways I couldn’t begin to break down…. here represented by these lines with arrows.
But some of the components are able to get energy from light or chemicals and gather
other molecules as nutrients. and in that way they supply themselves with the tools
to reset or remake the pieces and it continues the motion on its own.
Also another thing the cell machine can do is assemble other machines that are structured
very similar to the original. This is what allows us not to just see the machine. But
to continue to see the machine? Organisms breaking down or getting eaten is pretty inevitable,
if organisms didn’t assemble new organisms then all life would eventually end.
Those seem to be the differences. It’s like a multi-branched, reproducing rube Goldberg
machine that doesn’t stop. What do viruses fit in?
Viruses can kind of show us how central DNA is to the whole process. DNA isn’t just another
domino or cog in one stretch of the machine. It stores the information for the structure
of all the proteins of the cell. Since proteins basically do or control or build everything
in the cell, DNA controls what each component looks like, so it sort of designs the whole
machine and the processes it does. Different DNA means different components and
different processes. That’s why you can have a different set of
instructions come in and code for different proteins that do different things. In this
case, just make more DNA in capsules. Could you have that DNA come in and instruct
the cell to do something else? Like let’s say the a virus came in and told a cell to
make a bunch of enzymes or something. That’s fine I guess, that could theoretically exist.
But then after, you would never see that virus again. Just like with all DNA, viral DNA has
to code for something that helps that DNA reproduce or you won’t see it anymore.
It just so happens that there’s plenty of cells around for this viral DNA to interact
with without ever needing to code for or keep its own cell.
And it works well as a “strategy” that DNA can take. Viruses are one of, if not, the
most numerous organism on the planet. If they are an organism….
Are viruses alive? Maybe virus itself is an object that doesn’t
live any more than any other cell component. But a virus inside a cell is performing life
just like the other components of that cell. Are they an individual? I guess that depends.
Is the code the individual? Such that any set of DNA travelling and reproducing together
is 1 organism. Is the code with the cell the individual? since the cell is the smallest
unit that performs life. Or is it about how things are attached and that’s why we can
consider ourselves to be one organism. Same with those trees that can be an entire forest
large and thousands of years old since they’ve all stemmed from the same cloning root system.
I think “how things are attached” is the generally accepted definition of the organism.
But then where do viruses fit in? Is this one organism and this another organism? How
about now, is this an entirely new organism or is this more analogous to a parasite infecting
a host? Or is this just some special case since viruses aren’t alive at all so we don’t
even call them an organism. Maybe trying to point out which of these sets
of objects is alive as an individual life form distracts from the processes that demonstrates
what life is? Maybe life is the cycling interactions and
it doesn’t matter how it’s attached? Viruses have a discrete set of DNA with genes
that reproduce on their own incentives so it’s convenient to just call it an organism?
Anyways, I don’t know. I’m just talking outta me butt. Let me know what your butts have
to say in the comments. ….those blueprins aren’t evolving.
Keep in mind, it’s not the DNA itself changing. It’s just the information: the order of nucleotides,
that’s being copied and changed. New DNA is assembled with each new cell, and the old
DNA eventually falls apart. The thing that passes from one individual
to the next, is the information, for the order of the nucleotides. Overtime, the incidental
and random changes in the sequence, and whatever works long to reproduce again, results in
all the different genomes and organisms we see.

    I would argue that no, viri are not alive. They're inconvenient little shits of molecules that behave sorta like they're alive, but being sorta alive isn't being alive. Someone who sits a test and falls one point short of passing has not passed, how ever close they might have come. That's the dividing line.
    I sense that this problem is more one with language than with science. We know that viri are different from living things and that they are different from dead or inanimate things, the same way that we know that all living things are different from one another. Life is a very exciting property for stuff to have and that's why the debate as to whether or not viri should be considered living is so animated, but 'alive' is an individual property of an object just as much as 'yellow' is.

    Actualy what i can think of if that viruses are just an information, imagine you have program on your pc, then someone else is trying to change this program so he sends an "command" to it. And that what they bassicly are, the information/command for cell, evrything else is just effect of that information. And for ones that will say something like "but if its not alive, how it can take possesion over cell and change it", first of all, you dont need to posses something to change it, secondary… put a hand on hot stove…. seriously… stove its definytly not an organism but when is very hot it will change how your cells will work and deform them.

  • Reply deep hazarika December 15, 2017 at 5:39 pm

    oh! all this rambling. can you try to approach the problem from the most fundamental? can't you see that a virus is actually NEVER active? i mean a virus by default can't do anything, but more importantly even when they hijack a bacteria/cell it's always the cell's machinery which is used. on the other hand the cell/bacteria will ALWAYS have to be active. this may or may not define life but it's a un-ambiguous distinguishing factor between a cell/bacteria and a virus.
    also things become a lot clearer if you consider living things as complex adaptive systems

  • Reply AwkwardNoah February 5, 2018 at 2:21 am

    AFAIK A virus can't reproduce on its own, so it can't be alive?

    It's like a factory that makes bits of factories that come together to make a factory that can do the exact same thing. But a virus is like a piece? of a factory or a product of said factories. Because then it would be like saying a Hammer is a factory because it came from a factory and can be apart of factories. But the idea of a factory is larger than that of a hammer so a hammer isn't a factory but both a product and a piece of said factory. So I guess it isn't alive

    Everything in the known and I'll assume unknown universe can be catorized into one of three catorgories. Those are Animal, Vegatable and Mineral. Only the first two consits of what we've deemed as biological life, minerals do not. Separation ourselves from the Vegatable is not always accepted by human to an exact form. Animal and Vegatable have extremely close simularities in far to many numerious ways. Which leads to the undeducated having concerns and doubtls that casue for more of a separation then educated individuals will admit too; Though both agree on minerals!

    Humans are the only animal species that has the ability to consider ourselves above what WE deem as the lower forms. Ironically, we are also the only spiceies capable of exterminating our selves along with some of the other supposed lower forms. And though WE are aware of it, WE refuse to do anything about it unless there's a profit involved. Until such time as destroying any and everything conducive to mans existence is no longer profitable, it will continue. At which point the whole human existence will start again from scrach as it's done numerious times previously. The Egytians didn't build the Pyramids, nor did the Myans build theirs. They simple converted existing structors they came accross that managed to weather time long enougth. into structors for their own particular agendas. Hence all the various separate reasons individuals will state as to why they exist today.

    Tis ironic how some religions will state that man's existence is only 6 to 12 thousands year old. But were able to find the use of technology that we can't copy today. There's no known technoly or tools known today, even if one had sufficent funds that would allow modern man to build such a Pyramid such as the one's in Egypt or Sourth America. There fore it would stand to reason, they were built prior to the era or conception of what we refer to as Mankind. Assumably by a form of mankind that like ourselves will eventually do, and completly disapear from the surface of Earth leaving only extremly well built stuctors still in place.

    Dna is a map. Alive is something that uses the map. Viruses are like a box with a map in it floating through the sea. If a ship(something that already has a map) sees that box, they're probably gonna grab it and use it. Hence, changing course, changing maps. To me, yes, that's similar to a parasitic relationship in that often, the virus leads the ship off course. But not a parasite in that it doesn't always seem intentional malign. Imagine a virus that helps your body. Gives you superhuman strength. No longer a parasite, but still a forceful restructuring, and still benefiting itself. In a way, I guess you could consider most viruses parasites, and others, a lucky map.

What differentiates a virus from a river, a cell from a cat, a rock from a leaf? Everything is remarkably similar, especially considering vast time scales and less rigid definitions and/or theories. Think about a river, imagine every water molecule and from where they come who gives that to the streamlet who then gives to the river and the ocean in similar ways our blood and complexes deliver water and electricity (and rivers channel electricity too) up and through our system.

    The true wisdom of the ancients wasn't in recognizing that all things are alive, as New Age posits, but recognizing that there is no inherent difference between "living" things and inanimate things like rocks. That "living" things are just another type of thing. Even rocks respond to their environment, even fires die, even water has a life cycle. I don't think the conjecture around what defines life is capable of being meaningfully satisfied, because it's a division that obscures truth rather than reveals it. The truth is that life really isn't inherently different from a Rube-Goldberg machine, it just has more moving parts.
