I have come to consider this isomorphism between Bayesian inference and natural selection or Darwinian processes in general as a deep insight into the workings of nature.

You might like this. ("In fact, I realized, Bayes's rule just is the discrete-time replicator equation, with different hypotheses being so many different replicators, and the fitness function being the conditional likelihood. ")

Yes, thanks, and the standard mathematical description of the change in frequency of alleles over generations is given in the form of a Bayesian update where the likelihood is the ratio of reproductive fitness of the particular allele to the average reproductive fitness of all competing alleles at that locus.
