To me, the question should be inverted: what could Darwinian processes be an expression 𝘰𝘧? That would lead one to a transversal question about the general economy of nature. But maybe that is beyond biology, physics, or any methodologically manageable procedure.

Can natural selection be physicalized? Even if we can give an empirically consistent form of quantum Darwinism, I doubt we'll be able to render it completely continuous with its biological version.

Darwinian logic has been often recognized as a ubiquitous process happening in many natural strata. Dennett refers to natural selection as an 'algorithm', and Everett already talked in his long thesis about a branching process.https://twitter.com/_infinitography/status/1179144711984095233?s=20 …

The arborescent structure of worlds is a simple emergent structure from the interactions between the quantum system and its environment. The environment 'selects' the relative weights that the components will have in the following generation.https://twitter.com/_infinitography/status/1176225304156737536?s=20 …

In the (contemporary) MWI, the gap between the quantum and the classical is merely a quantitative one: certain components have higher weight (they're more "robust"), which allows them to be more frequently measured by the environment.

This analogy, by itself, can be applied irrespective of any interpretation of QM, given decoherence. But I think that where it's most useful is in the Many-Worlds Interpretation.

The key analogy resides in a functional identification of the mean fitness of a certain genotype (w) and the relative Born weights of the components of ψ. This implies that a higher probability of classically persisting in the environment is equivalent to being better adapted.

where ψ represents a wave function, α and β its different components and 2αβ the coherence effects between them; 𝑤 represents their respective fitness values
