One of the marvelous things about evolutionists is their ability to spout mutually contradictory statements next to each other without realizing how ridiculous they are talking. The only way selection insures some will proliferate and others will not is by killing them. Else both the mutants and non-mutants would proliferate and there would be no selection. Selection is a totally negative force, it only kills, it does not produce anything. To call such a "force" the agent of new traits, new abilities, new genes is totally ridiculous.
