You're being kind, there. It would be a hard thing to do to come up with an example of a "beneficial" mutation. Besides, mutations get "repaired", ie, nullified, in most cases.
Now explain to me why, under your ideas of what is and isn't a beneficial mutation, why a bacteria would have a mechanism to INCREASE its mutation rate during stress?
Why would a bacterial population WITH this mechanism to increase its mutation rate during stress survive better than a bacterial population WITHOUT this mechanism?
By all means, impress me with the explanatory and predictive power of creationism ............... .................................................................... ................................................................ ...............
