Did you know that the lines and wrinkles in your fingers create a unique pattern? All humans have fingerprints, and each person’s fingerprint is unique. Even identical twins don’t have the same fingerprints.
A person’s fingerprints develop even before they were born. The prints don’t change for the rest of a person’s life. Thus, they have been used to identify people for a long time. Records show that even people who lived thousands of years ago, like the Babylonians and the Chinese, used fingerprints to catch bad guys.
But fingerprints do not only help us identify people. They also help us grip and hold things. Without these prints on our fingers, we won’t be able to hold a pen or pick up a ball.
