1) mutations arise faster than selection can eliminate them;

2) mutations are overwhelmingly too subtle to be “selectable”;

3) “biological noise” and “survival of the luckiest” overwhelm selection;

4) bad mutations are physically linked to good mutations, so that they cannot be separated in inheritance (to get rid of the bad and keep the good).

I don't think that person knows about polyploidy or any of the other mutations that involve duplication of genetic code.

I think that person doesn't understand a lot about genetics.
