Scientists discover purpose of appendix

Evolutionists used to upset creationists by calling it a "vestigial" organ but that was itself a leap of faith -- faith in the completeness of their own knowledge. Being myself a REAL atheist, I am pleased to see that the appendix may be functional after all.

Some scientists think they have figured out the real job of the troublesome and seemingly useless appendix: It produces and protects good germs for the gut. That is the theory from surgeons and immunologists at Duke University Medical School, published online in a scientific journal this week. For generations the appendix has been dismissed as superfluous. Doctors could find no function for it. Surgeons removed them routinely. People live fine without them.

And when infected the appendix can turn deadly. It becomes inflamed quickly, and some people die if it is not removed expeditiously. Two years ago, 321,000 Americans were hospitalised with appendicitis, according to the Centres for Disease Control and Prevention.

The function of the appendix seems related to the massive amount of bacteria that populates the human digestive system, according to the study in the Journal of Theoretical Biology. More bacteria inhabit the typical body than human cells. Most of the bacteria are good and help digest food. But sometimes the flora of bacteria in the intestines die or are purged. Diseases such as cholera or amoebic dysentery would clear the gut of useful bacteria. The appendix's job is to reboot the digestive system in that case. The appendix "acts as a good safe house for bacteria," said Duke surgery professor Bill Parker, a study co-author.

The location of the appendix, just below the normal one-way flow of food and germs in the large intestine in a sort of gut cul-de-sac, helps support the theory, he said. Also, the worm-shaped organ outgrowth acts as a bacteria factory to cultivate the good germs, Parker said. That use is not needed in a modern industrialised society, Parker said. If the gut flora dies, they usually can be repopulated easily with germs picked up from other people, he said.....
