Life is limited, time is infinite, and evolution has no so-called end. Human beings have always maintained a curiosity and constantly explored the past. Have you ever felt strange to your body? I also imagined what to do if I had a long tail?
Maybe there are many mysteries in the body, we can not get accurate answers in a short time, but the body does have "defects", those tissues and organs that exist but do not affect health, everyone has more or less felt it.
Wisdom teeth are the products of human evolution. In a very old age, humans chewed raw meat and eaten it in a rough way, which naturally caused great wear and tear on the teeth. The existence of wisdom teeth can supplement prematurely lost teeth. Until now, wisdom teeth are somewhat redundant, and when they become inflamed, they can also cause pain.
The second is the appendix, which is located at the end of the cecum of . Long ago, its main function was to digest plant fiber. Our eating habits have long since changed, and the appendix has become a "lonely existence", which has no special effect on the human body. If the inflammation is cut off, it will not have a greater impact.
How many people know palm long muscles? Place your arm up, exposing your wrist, and stretch your fingers out so that you can see the palmar longus muscle on your wrist. Don't underestimate this muscle. Ancient humans were able to climb tall trees, jump and other movements, all endowed by this muscle. For modern people, it is undoubtedly "chicken ribs" and is no longer needed. Therefore, some people have been born without palm long muscles.
The last one is hair. Compared with our ancient ancestors, there are fewer and fewer hairs on our bodies. The remaining hair parts are very helpful to us.
For example: nose hair can block dirt, eyelashes dust-proof to protect the eyes, eyebrows prevent sweat from dripping into the eyes, hair regulates the body temperature of the head and so on. I have to marvel at the remaining charm of "taking the essence and removing the dross" in the course of human evolution.
I would like to share with you a very interesting little knowledge. Many people now have diarrhea when drinking milk, which is: lactose intolerance .What you don't know is that this situation existed more than 10,000 years ago.
Over time, some people no longer have lactose intolerance, and some people still exist. According to data, with the advancement of milk diet in the future, this symptom will gradually disappear.
As medical professionals, in their duties and due diligence, we always firmly believe that the mysterious human body has countless possibilities. In the future, the cancers and diseases that humans are afraid of will be evolved by time. Break through one by one.
