14 parts of the human body that will disappear in the future

The human body is an interesting place and it is so complex and unique that it is almost impossible to understand. Over time, our environment has drastically changed and so have our bodies. Some parts of our bodies are quite useless and don't really serve a useful purpose. These are 14 body parts which will eventually disappear in the future: 

#14 Body hair

Body hair is the terminal hair that develops on the human body during and after puberty. Our eyebrows help to protect us from sweat and prevent sweat from entering the eyes and on some level, male facial hair can help in attracting the opposite gender but apart from that, hair on the human body doesn't really serve a purpose. 

#13 Extrinsic ear muscles

The extrinsic ear muscles are the three muscles surrounding the outer ear. Some animals such as rabbits and dogs can move their ears independently because of these muscles. Most humans still have these muscles which are why some can wiggle and move their ears. However, they have no other purpose for humans. 

#12 Male nipples

Both men and women have nipples because, in the early stages of fetal development, an unborn child is genderless. This is why both males and females tend to have nipples. Men really do not need nipples and they lack the levels of prolactin to stimulate lactation and are unable to produce milk. 

#11 Palmaris muscle

This long and narrow muscle goes from the elbow to the wrist and is now missing in at least 11% of humans though this number varies greatly in African, Asian, and Native American populations. This muscle was useful in the days when we had to hang or climb things. 

#10 Appendix

The actual function of the appendix is unknown and some experts believe that the appendix is a useless remnant from our evolutionary past. This narrow muscular tube is attached to the large intestine and served as a special region to help in the digestion of cellulose. This was when the human diet consisted more of plant matter than animal protein. 

#9 Thirteenth rib

A cervical rib in humans is an extra and unnecessary rib which stems from the seventh cervical vertebra. It can also be known as a neck rib and it is due to a congenital abnormality which is located above the normal first rib. Chimpanzees and gorillas have an extra set of ribs. Most humans now have 12 but 8 percent of adults have an extra one. 

#8 Toes

Scientists have discovered that humans used to walk and balance on the midline of their feet but recently we have started to balance more toward the side of our big toe. Studies have proved that our center of balance is gradually shifting inward. This means that humans used to rely on toes for balance but do not need to do so anymore. 

#7 Third eyelid

This is also known as the nictitating membrane and is a transparent or translucent third eyelid which is present in some animals. Ancestors of birds and mammals had this for protecting their eye and keeping out any foreign debris. Humans only retained a tiny fold in the inner corner of the eye. 

#6 Arrector pili muscles

These are small muscles which are attached to hair follicles in mammals. These muscles allow animals to puff up their fur as a means of protection in the cold as well as to intimidate any sort of dangers. In the case of humans, contraction of these muscles can cause the hairs at the end to stand and this condition is known as goosebumps. However, humans have lost out on most of the fur but goosebumps are a sign that we were the same as animals in terms of this muscle. 

#5 Darwin’s point

This is a congenital ear condition which is known as Darwin's point. It is a small folded piece of skin which is located on the top of each ear and is occasionally found in humans. It is a residue of a larger shape which was used to help focus on distant sounds. This feature is now present only amongst 10.4% of the population. 

#4 Coccyx

This is a triangular arrangement of the bone which makes up the bottom/lowest part of the spine. It represents a vestigial tail and is also called a tail-bone. It is super useless for humans as it is what is left of the tail that most mammals use for balance and communication. 

#3 Wisdom teeth

Wisdom teeth are known to be extremely painful when growing and can cause a lot of discomfort and pain. When humans were still primitive, we had to chew a lot of plants in order to get the calories and nutrition to survive. Nowadays, only 5% of the population has these teeth. Let us hope that soon enough, we will be done with wisdom teeth for good. 

#2 Paranasal sinuses

This a group of four paired air-filled spaces which are around the nasal cavity. They have multiple different functions such as lightening the weight of the head, humidifying and heating the inhaled air, increasing the resonance of speech. However, people are unclear as to why we have retained these mucus-lined cavities except for the reason of getting a head rush or lightheadedness. 

#1 Subclavius muscle

This is a small triangular shaped muscle which is placed between the clavicle and the first rib. It stretches under the shoulder from the first rib to the collarbone. This muscle would certainly be a lot more useful and of need if humans were still walking on all fours. Some people have one of these, some have two, and some have none.
