Why are our fingers different in length? Some people might think that this is natural. We have been like this when we were in our mother’s stomach. Some people think that this is not the case during the fetal period. Later, it may be due to the different nutrients absorbed by each finger during the development process. So, what are the facts?
Let us uncover the truth of the matter. Let me talk about the first point of view. In fact, this idea that we are born with fingers like this is not correct. When we were a newly formed embryo, the length of each finger was almost exactly the same, only about one millimeter long. But as we continue to grow up, each finger slowly becomes different in length.
So, is this because each finger absorbs different nutrients during development? No, because our fingers are made up of cartilage cells that have been planned for growth. Each finger has its own unique genetic gene. We can understand that the different length of our fingers has been doomed since this time, and it has nothing to do with the amount of nutrition absorbed.
Expert research has found that every cell of the human body is affected by genetic genes, and the development of fingers uses a special “signal transmission molecule” to allow individuals to grow independently. Each finger receives its own signal to grow. The difference in signal determines their individual differences. This is why the five fingers are different in length. Why is there such a unique genetic gene? In terms of evolution, the five fingers have different lengths to meet different needs in life. The phalanx of the five fingers is radial, which can hold larger things to the maximum. When you need to grip something, bend your thumb to show the greatest strength; bend the remaining four fingers so that you can grasp the greatest strength. The five fingers are bent together, and the palm of the hand can be made into a nest to hold up small solids or liquids.
