Fingerprints, also known as handprints, are lines protruding from the epidermis. Because people's fingerprints are inherited, interact with the environment and are closely related to human health, everyone has fingerprints, but they are different. Because the fingerprint repetition rate is very small, about 654.38+0.5 billion, it is called "human ID card". Fingerprint is a line formed by the concave and convex skin of human fingertips. Fingerprint can increase the friction when the hand touches the object, so it is easier to exert force and grasp the object. It is naturally formed in the process of human evolution. Reaching out and observing carefully, we can find that there are three types of small handprints: concentric circles or spirals, which look like eddies in water and are called barrel lines; Some lines are open at one side, that is, like dustpan, called dustpan-shaped lines; Some lines are like bows, called bow lines. Everyone's fingerprints are different in shape, and the number and length of lines are also different. It is said that two people with identical fingerprints have not been found yet. Fingerprints begin to appear in the third or fourth month of the fetus and form around six months. When the baby grows up, the fingerprint just gets bigger and thicker, and its pattern remains unchanged.
