15 Parts of the Human Body That Will Disappear in the Future, Really?

4. Wisdom teeth

Early humans had to chew plants in order to get enough calories to survive, but these days only about 5% of the population has a set of these healthy yet useless teeth. We hope this one will be the first to disappear from the list — less dental bills!

5. Neck rib

A set of cervical ribs, possibly a leftover from the age of reptiles, still appears in less than 1% of the population. Some people have it only on their left or right side, while some have both. They often cause nerve and artery problems.
