Evolutionists just lost a major argument for evolution

The human appendix is no longer a vestigial organ. Or rather, it never was and scientists have now discovered that it isn't:

Apparently the growth is a sort of “safe house” used by good bacteria in the battlefield of our digestive tract. The good germs can hide in there while our bodies purge the bad germs in an ugly bowel-clearing process that happens when humans contract diseases such as cholera or dysentery, according to a study by Duke researchers in the Journal of Theoretical Biology.

Duke University Medical School professors said the wormish growth that measures between three-quarters of an inch to several inches long, is also a love nest for good bacteria where they breed and multiply.

As you can see from this article on a pro-evolution website, the now defunct argument about the appendix being vestigial was a major argument for evolutionists:

Conclusion: The vermiform appendix is vestigial

Currently, arguments against the vestigiality of the human vermiform appendix have been based upon misunderstandings of what constitutes a vestige and of how vestiges are identified.

From an evolutionary perspective, the human appendix is a derivative of the end of the phylogenetically primitive herbivorous caecum found in our primate ancestors (Goodman et al. 1998; Shoshani 1996). The human appendix has lost a major and previously essential function, namely cellulose digestion. Though during primate evolution it has decreased in size to a mere rudiment, the appendix retains a structure that was originally specifically adapted for housing bacteria and extending the time course of digestion. For these reasons the human vermiform appendix is vestigial, regardless of whether or not the human appendix functions in the development of the immune system.

From a nonevolutionary, typological perspective, the human appendix is homologous to the end of the physiologically important, large, cellulose-fermenting caeca of other mammals. Even though humans eat cellulose, the contribution to cellulose digestion by both the human caecum and its associated appendix is negligible. Regardless of whether one accepts evolutionary theory or not, the human appendix is a rudiment of the caecum that is useless as a normal mammalian, cellulose-digesting caecum. Thus, by all accounts the vermiform appendix remains a valid and classic example of a human vestige.
