15 Human Body Parts That Will Disappear In The Future

The world has evolved, and so has the human body, which has many parts that are no longer useful.

1. Body hair

1. Body hair

While the facial hair has a role, like for example the brows keep sweat from our eyes, most of the hair on our bodies serves no function.

2. Paranasal sinuses

2. Paranasal sinuses

Nobody really knows why we retain these troublesome mucus-lined cavities. One explanation may be that they make the head lighter.

3. Extrinsic ear muscle

3. Extrinsic ear muscle

While they are useful for some animals such as rabbits or dogs, they serve no purpose when it comes to humans.

4. Wisdom teeth

 4. Wisdom teeth

In early times, humans needed these to chew on plants and roots, but now only 5% of people have a set of healthy wisdom teeth.

5. Neck Rib

5. Neck Rib

1% of people still have a set of cervical ribs, possibly a leftover from the age of reptiles.

6. Palmaris muscle

 6. Palmaris muscle

11% of humans don't have this long narrow muscle which runs from the elbow to the wrist, once important for hanging and climbing.

7. Male nipples

7. Male nipples

The reason both men and women have nipples is that in the early stages of fetal development, the fetus is sexless.

8. Arrector pili muscles

8. Arrector pili muscles

The tiny muscles allow animals to puff up their fur in order to intimidate. Humans don't really have the fur anymore, so they are pretty useless.

9. Appendix

9. Appendix

The narrow muscular tube attached to the intestine used to help the digestion of cellulose, back when humans ate mostly plants.

10. Thirteenth rib

10. Thirteenth rib

8% of humans have an extra set of ribs, specific to chimpanzees and gorillas.

11. Toes

11. Toes

Scientists discovered that humans used to walk and balance in the middle of their feet, but now we have gradually transferred to balancing more toward the side of our big toe. According to researchers, our center of balance is still shifting inward, so don't rely on our toes as much. If the trend keeps up, at some point we won't need our toes any longer.

12. Coccyx

12. Coccyx

Also called a tail-bone, the coccyx is all that's left of the tail that most mammals use for balance and communication.

13. Third eyelid

13. Third eyelid

A common ancestor of birds and mammals may have had a membrane for protecting the eye and sweeping out debris. Humans retain only a tiny fold in the inner corner of the eye.

14. Darwin's Point

14. Darwin's Point

Some humans have a small folded point of skin toward the top of each ear. It may be a remnant of a larger shape that helped focus distant sounds.

15. Subclavius muscle

15. Subclavius muscle

This small muscle, stretching under the shoulder from the first rib to the collarbone, would be useful if humans were still walking on all fours. Some people have one, some have none, others have two.
