Evolutionary "Glitch" Claim of "Random Mutations"

I have seen the foolish taking root:

Job 5:3

Evolutionary Claim: “Random mutations are usually neutral or harmful but occasionally they confer a benefit to an organism. Natural Selection filters out the harmful mutations, causing species to evolve.”

"This is the central dogma of neo-Darwinism and is allegedly accepted by “virtually all scientists.” You will find it in literally 1,000 textbooks and 10,000 websites.

But I’m an EE. 

--I know that the information in DNA is a signal. 

--By definition, random mutations are noise. 

Telling a communications engineer that adding noise to a signal

sometimes create new, useful data structures is like telling a nurse you can occasionally cure a common cold by swallowing rat poison.
You’ll be hard pressed to find any communications engineer who, upon examining this claim, would agree with it.

Q: Have you ever had a data glitch on your computer that improved your files? Ever? 

--There is not a one single principle or practice in engineering that would ever suggest that this is actually true."
