What are the four major evolutionary defects of human body discovered by scientists?

As we all know, human beings are higher creatures on the earth, but they are not perfect in the history of human development and have experienced some bumps. According to the statistics of scientists, what are the four major evolutionary defects of the human body discovered by scientists? They are the spine, pelvis, wisdom teeth and retina. Next, I will take you to analyze it!

First of all, because of the spine problem caused by walking in a straight line, when humans learn to walk in a straight line, but their bodies don't seem to make corresponding adjustments, the spine will almost become a straight line with both ends bent. This will cause great pressure on people's waist, which is also the reason why young people will have different degrees of backache after working for a long time. The second is the difficult accident caused by the size of pelvis. Whether in ancient or modern times, dystocia is still a problem we are afraid of, and the risk of reproduction is great. The reason for this is that the pelvis is too small, and perhaps in the future, with more adequate nutrition, humans may not be able to give birth naturally.

The third is wisdom teeth, which are very common in our daily life. I feel that wisdom teeth are really a lot of redundant teeth for us, because in adulthood, we will always experience an unbearable pain because of wisdom teeth. In fact, wisdom teeth used to be the third tooth we used to chew food, but with the passage of time, our bodies are constantly changing, and it is time to pull them out when the bones are shaped. Finally, we usually see the retina of the world. Our retina is actually a degenerative process. Although our visual sense is very strong, it is really terrible compared with the compound eyes of animals, even the eyes with 360 degrees and no dead angle!

In life, we humans are not perfect. What is perfection? Therefore, each of us should be good at exerting our strengths to learn from each other's strong points, so as to grow up and strive to become excellent!
