15 Parts of the Human Body That Will Disappear in the Future

Posted on

In the first chapter of The Descent of Man, Charles Darwin identified roughly a dozen body parts that he gleefully described as “useless, or nearly useless.” Darwin’s catalog was far from complete — our bodies are littered with parts we don’t need. Let’s have a look at some of them.

1. Body hair

Our brows help keep sweat from our eyes, but male facial hair plays an equally important role in sexually attracting the opposite sex. Apparently, most hair left on the human body serves no function.

2. Paranasal sinuses

No one knows why we retain these troublesome mucus-lined cavities, except perhaps to make the head lighter.
