Did The Appendix Ever Have A Purpose

Although it is widely viewed as a vestigial organ with little known function, recent research suggests that the appendix may serve an important purpose. In particular, it may serve as a reservoir for beneficial gut bacteria.

The lowly appendix, long-regarded as a useless evolutionary artifact, won newfound respect two years ago when researchers at Duke University Medical Center proposed that it actually serves a critical function.

Only in 2007 did researchers finally offer a compelling case for the function of the appendix: the tiny organ appears to play a role in both the digestive and immune systems by acting as a storehouse for valuable bacteria, which are enlisted when the gastrointestinal tract loses its beneficial gut flora.

“We also figure that the appendix has been around for at least 80 million years, much longer than we would estimate if Darwin’s ideas about the appendix were correct.”

What was the appendix originally used for?

Some studies suggest that as ancient humans were predominantly herbivorous, they used their appendixes for digestion. However, as humans evolved, they started to include more easily digestible food in their diet and the appendix eventually lost it function.

Was the appendix ever useful?

Why do humans have appendix?

What happens to your body when you don’t have an appendix?

If you do not have your appendix anymore, you may be at an increased risk of recurrence and even death when confronted with a pathogen like C. diff., cholera or any of a wild kingdom of other pathogens.

When did we stop needing our appendix?

Does having your appendix removed shorten your lifespan?

What are the long term effects of not having an appendix?

Some studies have shown, however, that people without an appendix may have slightly higher rates of infection than those with a functioning organ. “It may also take them slightly longer to recover from illness, especially those in which the beneficial gut bacteria has been flushed out of the body,” Smith added.

Why can a person live a normal life without an appendix?

If the appendix disappeared in a modern society after the Industrial Revolution, people would have antibiotics to help them survive, Parker said. However, without an appendix, people would not have the appendix’s reservoir of helpful bacteria to help them recover from harmful infections.

Does having no appendix affect your immune system?

It doesn’t have a specialized role in your immune system that would be lost if it weren’t there. What’s more, the appendix doesn’t function in human digestion.
