The Human Appendix

The other day, Lauren mentioned to me that her anatomy professor was teaching the class that the appendix is a functionless organ.  This view, that it is a vestigal organ, a remnant of evolution, is certainly a common one.  There is, however, no real reason to believe it.  What follows is a collection of articles I have found, either directly via google search, or indirectly via the references in other articles (some of which are here).
