What does the appendix (then one in the intestine serve for)?

iirc it serves as a reservoir for gut microbes

not a biologist though

So as to be able to repopulate the gut if there is some kind of antibiotic event. Fill up all the space with safe microbes before something invasive comes along and establishes itself.

This apparently. It also helps in mucosal immune responses.

The theory is that it is a remnant of a cellulose digesting cecum like it is found in cows and other herbivores. Evolution didn't get rid of it completely in humans because of the aforementioned incidental usefulness.
