Then, how do rocks reproduce themselves? — Galuchat
They don't, clearly. There is no mechanism of heritability among populations of rocks. All I've argued is that evolution can be applicable to non-organic populations, not that all non-organic populations undergo evolution. — StreetlightX
These are all just small examples from disparate fields, but I hope they begin to fill out a picture of how to understand evolution as not just an organic process, but an inorganic one as well. — StreetlightX
Why do we need to do that? What's at stake in thinking the nonliving in evolutionary terms? — Πετροκότσυφας
Going by the orthodox qualifications of evolution which you’ve stipulated, evolution necessarily in part consist of self-replication. — javra
Evolution is an inorganic process insofar as it involves interactions between the organic and the inorganic. Nonetheless, arguably, the organic aspect is predominant.
Language, architecture and technology should be considered predominately organic, too, because they are activities associated only with organic beings. Of course they, just like organic beings and evolution itself, involve inorganic materials and aspects of the environment, but that does not mean that they are not predominately organic processes.
None of this is to say that there cannot be wholly inorganic evolution. The evolution of the pre-organic cosmos, for example. — Janus
If evolution is claimed to be substrate independent, it needs a general description which can be applied to all types of objects, otherwise the notion is category error.
And if the terms used in such a description (notably "reproduction") can only be (or are usually) understood with reference to the life sciences, they require redefinition (which is equivocation). To avoid equivocation, they need to be replaced or supplemented with other terms/concepts. — Galuchat
I simply mean to say that the fact of evolution is indifferent to the mechanics - it only requires that there be some/one; but once there is one, it's specificities will have, at it were, retroactive effects upon the actual workings of evolution. I hope that's clear). — StreetlightX
Can replication occur in the absence of agency? — javra
My hunch is that this is mostly because we're talking about simulation, if I'm not mistaken, which, in a way, gets rid of time and space, since they are simulated too. I mean, the architectural designs that got extinct by our algorithms, haven't existed the way extinct species existed in spacetime. It's a different milieu to use one of your expressions. So, I'm thinking that this evolutionary talk in design is mostly a metaphor for something that we were doing either way (selecting designs based on preferences), just not as efficiently or systematically as the new algorithms allow us to do? — Πετροκότσυφας
Evolution gave rise to life's precursors, the living emerged from the nonliving at some point. — fdrake
Hurricanes, sand dunes, and rivers, for example, are 'replicated' all the time given the right atmospheric/geological/hydrologic conditions [...] — StreetlightX
So at the very least what distinguishes life from other, natural, self-organizing systems is a mechanism of heritability and an ability to self-maintain - the two key components of autopoietic theory. Of these two components, I'm fairly convinced that the universality of DNA as a replication mechanism is, despite it's universality, a contingency due to shared ancestry, rather than an intrinsic component of life itself. — StreetlightX
So going back to the question of agency, the question is: where can we locate it? There are - on the outline above - three possible places (at minimum). (1) At the level of sheer reproduction (hurricanes, etc); (2) At the level of the mechanism of heritability (DNA expression, epigenetic processes of methylation, etc), and; (3) At the level of self-maintainence processes. — StreetlightX
Complications arise when it becomes clear that one can't cleanly and analytically separate (2) and (3): in order to heal a cut, they body draws upon DNA in order to grow new skin to do so. So the question is: it is analytically necessary that processes of self-repair draw upon mechanisms of heritability? What is the modality of the connection between (2) and (3)? — StreetlightX
A hurricane is always created anew; it is not 'path dependant' on the phylogenesis of other, previous hurricanes. — StreetlightX
Might be helpful to use a word like "development" for changes an individual undergoes during its lifespan, and reserve "evolution" for populations. — Srap Tasmaner
Might be helpful to use a word like "development" for changes an individual undergoes during its lifespan, and reserve "evolution" for populations. — Srap Tasmaner
That's the difference between biological and non-biological evolution; there is no self-organization involved in the formation of hurricanes, rivers and sand dunes.
An individual hurricane, river or sand dune evolves over its life just as organisms do. The idea of evolution you seemingly want to address, though, is the idea of the evolution of successive forms in the history of a population and not the evolution of individuals.
It is possible that there could be an evolution of successive forms of hurricanes, rivers or sand dunes; but this would be entirely due to 'external' environmental and climatic changes, not to 'internal' heritable changes in their constitution.
The question then becomes whether in the example of say, AI, programming could become a heritable self-organizing substitute for DNA. — Janus
Languages, like organic species, go extinct and die; — StreetlightX
self-organization is most definitely a property of non-living things. Hurricanes are textbook examples of self-organising systems driven by entropic gradients. — StreetlightX
I'm concerned here with evolution in its strict sense - heritable variation in populations - rather than development over a lifetime.
Finally, with respect to mechanisms of heritability, there is nothing about the principles of evolution that require those mechanisms to be 'internal' and not 'external', as it were. In fact, as I mentioned to Jarva, 'external' mechanisms are currently acknowledged to function in an evolutionary capacity independently of 'internal' mechnisms like DNA. That is, whether or not such a mechanism is 'internal' or 'external' to the subject population is a matter of indifference to the evolutionary process (cellphone blueprints and their factories are not contained in cellphones!).
