Mutations change information. Any breakdown in the code that results in non viability is immediately removed. Any breakdown in the code that results in reduced reproductive success is eventually removed. What is left behind is an increase in useful variations.
I asked previously “where did these variations come from?”. If immediately after the Flood there was a maximum of four alleles at any genetic loci - and now there are many species supposedly derived from each “kind” of animal - and much more genetic diversity in each species than just four different types of alleles - WHERE DID THESE VARIATIONS COME FROM?
Why do you suppose bacteria would have an error prone DNA polymerase that would be expressed during stress that would introduce mutations into the genome; if such modifications of its code would lead to detrimental outcomes?
Did you, in your pomposity, miss this critical fact and its obvious ramifications?
Very simply the ‘junk’ DNA as you prefer to call it.
All changes that allow for adaptation and survival had to be pre-programmed into the code by a higher intelligence.
Mutations simply do not increase the amount of information.
