Your workmanship is marvelous—how well I know it.
Psalm 139:14 NLT
"A mutation is simply an inheritable error that occurs when DNA is copied. A long-standing assumption of biological evolution was that mutations are completely random. This is what most evolutionists
believed, and this is what most students have been taught. This randomness is important for evolution theory because it allows for any and all possible mutational changes to happen. A series of discoveries have proven that assumption to be false.
A recent study found something previously unknown in the plant Arabidopsis thaliana. Also known as thale cress, A. thaliana is one of the ‘workhorses’ of modern molecular genetics.
Associated with the DNA in chromosomes is a group of proteins known as histones. Their usual role is to provide structural support to the coiled DNA that makes up the chromosome. By wrapping around and around histone proteins, DNA is also able to attain an incredibly compact conformation. The researchers discovered that certain portions of the plant’s genome are surrounded by specialized histones that have chemical markers which detect mutations and release chemical signals to bring in DNA repair proteins.
Copying errors (‘typos’ in the DNA, as it were) take place regularly in the complex process of DNA replication. But they will often be repaired by the cell’s machinery.

As a result, the error is not passed on to succeeding generations as an inherited mutation.
This study indicates that certain parts of the genome, particularly in areas essential to the organism’s functioning, are more likely to be repaired, and thus less likely to suffer mutational change, than other parts.

Monroe said he was shocked to find this indication of non-randomness in the process of mutation, as he had been taught the opposite as far back as high school.
The article, however, was quick to perform damage control for evolution with this throw-away line: “The new finding does not disprove or discredit the theory of evolution, and the researchers said randomness still plays a big role in mutations.”
However, there was no attempt to explain why this was not a problem for evolution, just a fact-free assurance that boils down to nothing more than: ‘Don’t worry, don’t doubt’.
And the genes that control this process, the very ones that would have needed to be changed by mutation in the evolutionary scenario, are exactly the kind that these special histones would prevent from mutating.
The genome appears to be designed to resist the major evolutionary changes that are needed to create the extreme diversity seen among living things. These specialized histones are another example of this design."

Those processes would need to have morphed from one strategy to another over time, but the mutations required would affect reproduction, and successful reproduction is required for the supposed evolutionary process.
