The Appendix is Useless

Even in the scientific community, where it was believed to be a vestigial organ left over from millions of years of natural selection that had failed to excise it from the human body, the appendix has long been considered to be entirely worthless and is known for becoming inflamed or rupturing.

This is a fallacy about evolution. If so, what is the appendix useful for, though? The appendix, however, maintains healthy intestinal bacteria, according to Heather F. Smith, PhD, an associate professor at Midwestern University Arizona College of Osteopathic Medicine.

She discovered in her study, which was published in the journal Comptes Rendus Palevol, that the appendix had independently evolved in 30 various species of animals and had only rarely vanished following this evolution. Because it contains immune system tissue, the appendix has also been connected to the control of the immune system.
