Which unnecessary body parts are those? The appendix is there to repopulate the intestines with beneficial bacteria when they get wiped out. Extra kidneys, lungs, etc., are there because that's what naturally happens with bilateral symmetry, and provide useful redundancy. I'm having trouble thinking of other "unnecessary" ones.

The thing, I'm having trouble too. My anatomy knowledge is kind of bad and I might just have repeated something without making sure it's right first.
