15 Body Parts That Will Disappear One Day
15 Useless Body Parts That We Don't Really Need. We can surprisingly live without these 15 body parts.
If you ever thought that all people are built the same, think again. If you thought that all our body parts are vitally important, you were not right again.
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 the parts we don't need.

SUMMARY
- Apparently, most hair on the human body serves no function, so it is very likely to get extinct in the future! Besides brows perhaps, they keep sweat from our eyes.
- And we have a lot: frontal, ethmoidal, sphenoidal, maxillary sinuses. In fact, no one knows why we still have these troublesome mucus-lined cavities!
- Some animals, rabbits, and dogs, for example, can move their ears independently. How does it happen? Thanks to these exotic-sounding muscles. But you know what? People also have them!
- As human jaws have become smaller in the process of evolution, the rest of people simply don’t have space in their mouths for these teeth! Back in the days when toothpaste didn’t exist, they were kind of backup grinders.
- Have you never heard about neck ribs? It is a set of cervical ribs, possibly a leftover from the age of reptiles. They still appear in less than 1 percent of the population.
- There is a long narrow muscle running from the elbow to the wrist. It is already missing in 11 percent of humans today, so it is a safe bet that with time it will disappear completely.
- Nipples are present in both males and females. Men generally lack the necessary levels of prolactin to stimulate lactation and typically cannot produce milk.
- Goosebumps are the indicator of them at work. We get them when we are frightened, amazed or cold. Apparently, we have lost most of the fur and acquired warm clothes. We don’t need any additional protection from freezing temperatures or the source to intimidate our rivals anymore.
- Some research shows that an appendix can be, in fact, useful! It might store special bacteria good for those who suffer from diarrhea.
- Our closest cousins, chimpanzees, and gorillas have an extra set of ribs. What about humans? Most of us have 12, except for 8% of adults - they have an extra one!
- It's all that is left of the tail that most mammals still use for balance and communication. What is more, there have been 100 documented cases of babies who were born with a tail. What is the purpose of a tail-bone? There is none.
- A third eyelid, you will ask, do we have it? Yes, we, humans, retain a tiny fold in the inner corner of the eye. It is what is left from membrane birds, and mammals have had for protecting the eye and sweeping out debris, at the same time providing visibility.
- Darwin's point is a small folded point of skin toward the top of each ear that is occasionally found in modern humans. It may be a remnant of a larger shape that helped to focus distant sounds. Nowadays only 10% of people have this “greeting from the past.”
- Subclavius muscle is a small muscle which stretches under the shoulder from the first rib to the collarbone. It would be beneficial if humans were still walking on all fours.
- Scientists have found out that humans used to walk and balance more in the middle of their feet, but now we have gradually transferred to balancing more toward the side of our big toe.
