Why would cells be programmed to elicit an increase in mutations during stress if mutations are not amenable to deriving selective advantage to overcoming that stress?

A cell “knows” when it is undergoing stress because it has evolved molecular signaling mechanisms that elicit a stress response. One of these responses is to deliberately increase its mutation rate.

A cell “knows” it has derived a selective advantage due to genetic variation when its offspring out-compete those without that genetic variant such that the population becomes overwhelmingly the descendent's of the cell that derived the genetic variation that best overcame the stressful conditions.

I am afraid that only “Darwinists” (i.e. evolutionary biologists) are conducting ANY research in this or any other field of Biology. The I.D. movement is bereft of any research and neither do they plan on ever doing any. And I know why.

You’re assuming that the mutations themselve are completely random. But what if each mutational move has a goal?

==A cell “knows” when it is undergoing stress because it has evolved molecular signaling mechanisms that elicit a stress response. One of these responses is to deliberately increase its mutation rate.

Fine. First, how does the cell “know” it’s under stress? If the cell deliberately increases its mutation rate, then at a very minimum the mutation rate IS NOT RANDOM.

==A cell “knows” it has derived a selective advantage due to genetic variation when its offspring out-compete those without that genetic variant

But wouldn’t the cell’s offspring out-compete those without said advantage under either scenario? Wouldn’t you have to set up controlled experiments to determine whether the cell is self-selecting, or is being naturally selected, or both???

Could this be because Darwinism is a state sanctioned religion that has taken over our science institutions, brooks zero dissent, and that we are forced to pay for with our tax dollars whether we agree with the religion or not?

Not true. Creation and ID scientists don’t have the luxury of labs and research grants paid for by the US taxpayer, but they do nevertheless carry on research. Look at the ID research the Templeton Foundation is funding, or read the Journal of Creation. Both camps are cranking out new research in support of Creation/ID all the time.
