I also noticed you avoided the relevant question.

You said that a bacteria increased its mutation rate in order to increase its chance of survival. That is absolutely correct!

So what is it about a high mutation rate that would confer a survival advantage to a bacteria under stress?

Nope. The relevant question was your misrepresentation of what I wrote. All other comments were inferior to that.

"So what is it about a high mutation rate that would confer a survival advantage to a bacteria under stress?"

It is obvious that it is searching a 'design-space' for potential alternatives, much like a Thompson Array; an intelligently-designed search method.
