The current paradigm assumes a uniform probability of mutation across all genes. But maybe there are mechanisms that say “keep this part of the genome under tighter control” and “make this other part of the genome more susceptible to mutation.”
In the short term (single digit generations) that’s probably true, but I don’t see how it could be on longer scales. If the random mutations decrease fitness, they won’t be passed on at some point, since there is less reproduction. If they increase fitness, they will be passed on to more individuals.
That evolution is purely randomness + fitness landscape rather than that DNA guides the process at least somewhat. Don’t burn me alive guys
I don’t understand your point but it seems interesting. Could you rephrase?

I would expect randomness to play a larger roll than fitness.
