[MrB]

the vast majority of mutations are not beneficial

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.

Beneficial mutations happen all the time. If I subject a bacterial culture to heat stress, the bacteria has a mechanism whereby, under stress, its mutation rate increases. Mutations that enable the bacteria to survive heat are now “beneficial” and accumulate through natural selection.

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 ............... .................................................................... ................................................................ ...............
