I'm not sure what you are responding to, but it isn't anything I said.
You just didn't understand that saying, "The point is that evolution included both beneficial and neutral changes. There are lots of mutations and chromosome changes that are synonyms or which have no immediate noticable effect.
Brings the whole reason as to *why* there are so many 'neutral' changes. That is a function of the fault-tolerant *design* of the triplet-codon, diploid, information-coding system.
