I'm not saying this proves evolution, I just found this to be interesting.
As we all know, the human appendix is a vestigial structure, meaning that it serves no known purpose (some argue that it is made out of lymphatic material and is part of the immune system).
A handful of people have been found to be born without an appendix. Since the appendix supposedly has no purpose, is it evolution at work that few are born without these vesitigal organs, or is it simply a genetic defect?
Afterall, no one has been known to be born without a coccyx (tailbone, also vestigial) or without a gall bladder (serves a purpose in digestion, but most people can easily live without it).
