Mutation is random, it is not accidental. The process of replicating DNA itself causes mutation. The mutation can occur at any random codon. It is not an "accident" because it is not unexpected, nor is not undesirable for a species to have mutations (although the specific mutation is probably neutral or harmful).


ran·dom
Of or relating to a type of circumstance or event that is described by a probability distribution.
Of or relating to an event in which all outcomes are equally likely

ac·ci·dent An unexpected and undesirable event, especially one resulting in damage or harm. An unforeseen incident. Lack of intention; chance.

The only part of the definition of "accident" that applies to my argument is the last: "Lack of intention; chance."

I would also point out that, WRT mutation, it is difficult to demonstrate that "all outcomes are equally likely." Further, mutations are only described by a probability distribution if their occurence is governed by chance.
