Hello, gezginbekir.

DNA has a very complex structure, and random effects can only damage it.
You must not have read the entire thread. Pink Sasquatch gave an
example of a mutation that turns out to be beneficial.

They say that the partial immunity to malaria by those with the illness is a "gift" of evolution.
There is another mutation, one that produces
Hemoglobin C, whose adverse symptoms range from very mild to non-existent, which also confers protection against malaria -- this sounds like another beneficial mutation.

So for that reason, as Grass puts it, "No matter how numerous they may be, mutations do not produce any kind of evolution."
It appears that this is beyond the scope of this thread, which is concerned with beneficial mutations, but I want to say that this quote is correct. Mutations do not produce any kind of evolution. Natural selection produces evolution.
