I'm not sure calling me right in this instance is the best start to an authoritative refutation of my thesis.

I am not appealing to nature (please read the article you linked to) I'm appealing to evolution.

I have had my jabs, including malaria, small pox, MMR, and tetanus at least. My Dad has a pacer. The appendix is a funny one because recent research indicates that it might simply act as somewhere for bacteria to accumulate ie a sort of biome generator or refresher, rather than simply being a hangover from something else. Given the way evolution "works" it seems to me that there was an additional useful function that the vestigial appendix carries on doing that means we still have them.

Evolution does not use a drawing board and beautifully rendered isometric drawings and a series of briefings before getting marketing involved. If it works it stays, if it changes a bit and still works and the owner happens to procreate, it might stay. If they die too early it might not stay. Rinse/repeat. Genes (selfish or generous), structures and amalgams and who knows what else, changing and morphing, evolution is a process that should not have a name because it isn't really a process that starts from A and goes to B. It starts from A and might happen to hit L which is quite close to B, which is nice. The biggest problem is that us humans like to slap a tag or a name on things to contain them and then misuse those names rather badly. Hence we get "intelligent design". Evolution is far more fascinating and sophisticated than anything that "intelligent design" could possibly come up with, whilst being far less sophisticated than "ID" - yes I am aware that is a tautology but it seems appropriate. Funnily enough, intermediate steps in eye development have been sighted in the wild.

I'd have added cancer to your list for a proper challenge.
