absolutely nothing. Well that is what we thought. A new theory published online in a scientific journal this week states scientist may have found the reason for the appendix. The appendix protects the good bacteria in our gut. When a virus wipes out all of the good bacteria in the gut it is the appendixs job to get the good bacteria going again.
We can live without the appendix now because we pick up the good bacteria we need from other people we come into contact with. Before we became industrialized and the population was more spread out it did its job by restarting the production of good bacteria thus keeping our guts healthy. Since our cities have become larger and we live in closer proximity to each other the appendix does not play a large roll in our survival.
