- Some human body parts have become useless over the past few million years.
- Useless body parts include the appendix, the tail bone, and the muscle fibers that produce goose bumps.
Some human body parts serve no purpose despite once having a specific function among our ancestors.
The appendix, for example, is not an essential body part (though $4 it may act as storage for good bacteria). In some cases, the appendix gets inflamed or ruptures, which requires surgical removal of the organ.
Several other body parts used to be important for humans' survival, but they have since become useless. Some of them can be removed, and their absence does not lower people's quality of life.
Take a look at nine of the most useless body parts.
