Also, the worm-shaped organ outgrowth acts like a bacteria factory, cultivating the good germs, Parker said.
That use is not needed in a modern industrialized society, Parker said. If a person's gut flora dies, they can usually repopulate it easily with germs they pick up from other people, he said. But before dense populations in modern times and during epidemics of cholera that affected a whole region, it wasn't as easy to grow back that bacteria and the appendix came in handy.

Did they get that from some actual research, or make it up?
(I don't know enough to rule it out, since it sounds like something that could happen.)
