The *reason* why most new mutations are neutral or deleterious is

has changed from the conditions of the organism's ancestors.

It would be better to be concrete than engage in explanations on the
nature of gene mutations, which hardly anyone here in TO needs.

IOW don't confuse me with the facts i've made up my mind.
