Why would a bacteria under stress express error prone DNA polymerase instead of the usual high fidelity DNA polymerase if genetic change is “mostly of an entropic nature” that “doesn’t move the genome towards higher or better functioning”?
Apparently the mathematics of bacterial population dynamics ‘thinks’ that by introducing mutations during stress it can adapt and overcome the stress and better survive - i.e. better functioning.
Why would a bacteria have error prone DNA polymerase in the first place if most genetic changes were “entropic”? And why would it be expressed at times of high stress?

Simple. Because error itself is entropic.
