The Appendixby Desert Surgical Associates on 04/01/18
Scientists say the appendix might have been a place for good bacteria to localize in, like a little cul-de-sac away from everything else.
The theory is the appendix serves as a nature reserve for beneficial bacteria in our guts. When we get a severe gut infection such as cholera (which happened often during much of our history and happens often in many regions even today), the beneficial bacteria in our gut are depleted. The appendix allows them to be restored. In essence, Parker sees the appendix as a sanctuary for our tiny mutualist friends, a place where there is always room at the inn. The appendix nurtures beneficial bacteria even as our conscious brains and cultures tell us to kill, kill, kill them with wipes and pills.
