The Appendix is Still Vestigial

I was reminded of a recently published paper that argues that the human appendix has a function--that it acts as a kind of storage area for commensal (helpful) bacteria. I have not read the paper, but apparently it really only contains a hypothesis (ie. no experiments or data collection), and anyway, even if this hypothesis is correct, it does not change the vestigial nature of the appendix.

Douglas Theobald explains at The Panda's Thumb and in his article at talk.origins--the two should be read together.
