Hardware and Software analogy,
or perhaps operating system and application analogy.
So, even if DNA “mutates” (software/application changes),
the operating system and hardware still need to function,
and the whole system obviously isn’t the product of mutation and selection over billions of years.
It's amazing how often the 'intelligent design' analogy comes up wrt biology.
Yet naturalists deny to their last breath that life is intelligently-designed.
