9 body parts we no longer need

In light of the news about the editing of the human genome, ideas about cosmetic or even functional body transformation no longer seem like fantasy. The other day, Boston College compiled a list of 9 rudiments of the human body, some of which can be removed without harm to the body.


Millions of years ago, this intestinal process helped digest fiber-rich plant foods. Since then, both the human diet and his digestive system have changed, the need for a complexly arranged intestine has disappeared. The appendix is ​​not beneficial, but the harm from it is known.

Palmar muscle

About 3.2 million ago, humans became upright, the ability to climb trees ceased to be vital. The long palmar muscle, palmaris longus, is only needed for this - today it simply takes place in the body.

Heavy Duty Jaws

Today we eat cooked food that doesn't always have to be chewed. There is no longer a need for powerful jaws capable of tearing off pieces of flesh, crushing nuts and bones. It is not necessary to remove the jaw, but making it smaller and more accurate is a worthy task.


The muscles that cause the surface of the skin to tighten and bulge hairs are called Arrector pili. They are useful for creatures with abundant fur - cats rearing fur for the sake of a frightening look, porcupine preparing needles for a fight. Practically hairless people do not benefit from them.


For bipedal creatures, the tail is of no benefit, even a little interfering. Therefore, there is also little good from its rudiment, the coccygeal bone. Once humanity parted with its tail, now it is time to bring this process to the end.

Ear muscles

We still have muscles that move our ears, but control over them has long been lost. Yes, and there is no need - a person has a flexible neck and turns his head in the direction of danger, not limiting himself to ears alone. Some people still have the ability to move their ears, but it gives nothing but a comic effect.

Pyramidal muscle

Already 20% of people do not have such muscles, the rest have two or less. They are located in the lower abdomen and do not help in any way with body movements, although they can indirectly affect the appearance.

Men's nipples

Human embryos develop as female - only at a certain stage of the process, under the influence of testosterone, they turn into male. However, by that time, the embryo already has time to form nipples, which do not have any functional load in the male body.

Third eyelid

A fold of fabric, similar to a membrane in the eyes of amphibians or birds, which with its help cover them from debris. The primates from which man originated, in their mass, have lost it, and if the third eyelid grows, man cannot control and use it for its intended purpose.
