The more we study the human microbiome, the more it appears to be a moving target. Recently, a story in Scientific American suggests that that target may be even more elusive then we think. It speaks of a scientist named Bill Parker who has defied the common notion that the appendix is a useless organ, left over from our prehistoric days. Instead, he has been searching for the answer of just how it functions as part of our bodies, and he has come up with a pretty interesting hypothesis: that the appendix may act as a reservoir of bacteria for the gut microbiota. The article, written by Rob Dunn, is available here and definitely worth a read, as is one of the papers mentioned in the article.
