Ideas are useless, but the appendix seems to play a very important role

The appendix turns out not to be excessive, but plays a rather important biological role in the body.

Our bodies have many parts that really have to be called . useless. Wisdom teeth are a good example, and certainly no missing appendix.

In fact, appendicitis is a part with no role, it is easy to be infected, like a bomb exploding slowly waiting to explode. Many people even try to cut off these extra parts even when they are not.

However, recently, according to a study from the Midwestern University, it seems that the appendix plays some important biological role, because humans are not ready to give it up.

Why not remove the appendix?

Specifically, the expert team decided to monitor many generations of over 533 animals. Do they observe if the appendix is ​​ever lost or will appear in future generations?

As a result, the appendix re-exported at least 29 times, even up to 41 times during their entire evolutionary journey. Only 12 times completely disappeared.

"This data is a solid proof that the rate of appendicitis is greater in terms of a selection of evolutionary rules, " the team said. "We can thus eliminate the appendix hypothesis as a remnant of evolution."

For years, scientists have always sought a specific effect of the appendix. So far, the most compelling evidence is that the appendix is ​​like a good place to store bacteria , which can prevent some harmful bacteria from entering.

And now, experts have approached in a different direction and have been effective. According to experts: "The intestine almost never disappears in the evolutionary chain once it has appeared." Although "useless" , but the body never denied it, even if the price was too expensive.

Records from the research group show that the organisms with appendicitis often have a high concentration of lymphoid cells (lymphocytes) - also antibodies - in the cecum . That proves that the appendix has a very important role in the organism's immune system.

The appendix has a very important role in the immune system of the organism.

"In fact, the relationship between appendicitis and lymph nodes in the cecum has been debated, but this is the first time it has been confirmed by specific figures" - the group responded.

Research still has a lot to do before officially making conclusions. From then until then, just let our pitifully leftover parts stand still.

The study is published on Comptes Rendus Palevol page.
