Not That Useless

Long considered to be a useless appendage, scientists are now discovering that the appendix has a purpose and is far more prevalent in nature than once thought.

Scientists have discovered that the appendix can be a source of good bacteria to repopulate the gut after a severe case of diarrhea. The appendix can also help make, direct and train white blood cells.

More astonishing is the fact that scientists now consider the appendix to have been around for ~80 million years. If true, this means that the view of the appendix being a vestigial organ (an organ rendered useless due to the ongoing phenomenon of evolution) would be incorrect. Moreover, scores of other animals also possess this appendage, oftentimes aiding in digestion.
