Random mutation is so attractive to chance worshippers because it is easy to demonstrate that unpredictable mutations do happen and that, in principle, any possible outcome can be produced. This is to say that, for instance, a shower of cosmic rays can hit a group of people and change the DNA in their germ cells in any manner whatsoever. It’s just a matter of how probable any given change might be. No change is impossible. Set incredulity aside and the comic book characters “The Fantastic Four” become real possibilities. Hence random mutation can explain ANYTHING and the only argument against it is the argument from incredulity. That’s why it just won’t die. It’s too good at its explanatory ability. Nothing in biology is impossible in light of all powerful random mutation. Even better, because random mutations are by definition unpredictable, there’s nothing to get in the way of it being disproven – no predictions made means no predictions failed. It isn’t science. It’s “Accident of the Gaps” or as I like to call it “Darwin of the Gaps”. Incredible! Literally, incredible.
