In the main section of The Descent of Man, Charles Darwin recognized around twelve body parts that he merrily depicted as “futile, or about pointless.” Darwin’s inventory was a long way from finish — our bodies are covered with parts we needn’t bother with. How about we examine some of them.

2. Paranasal sinuses
Nobody knows why we hold these troublesome bodily fluid lined pits, aside from maybe to make the head lighter.
