Speaking of that kind of thing: here's much ado about a thing that in some people's worlds does not happen. A web page on mutations, repair mechanisms, etc.

I like the part where one kind of recurring thing that doesn't happen damages a repair mechanism for that thing that doesn't happen and the organism which doesn't have that mechanism rapidly and reliably gets lots more of that thing that doesn't happen.

Intelligent Designers, if they were curious, might be interested in whether and why some parts of the genome mutate at different rates. It would make an interesting research project.
