Why Do We Have Appendix?

Researchers deduce that the appendix is designed to protect good bacteria in the gut. That way, when the gut is affected by a bout of diarrhea or other illness that cleans out the intestines, the good bacteria in the appendix can repopulate the digestive system and keep you healthy.

What was the appendix originally 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.

Do we need our appendix?

Why do we have an appendix? The entire digestive tract helps with our immune system, but some scientists and doctors think the appendix may be a place for our body to store certain healthy types of gut bacteria that otherwise could be altered or changed during an intestinal illness or with overuse of antibiotics.
