Imagine your skin is like a piece of clay that gets squished and stretched when you’re growing up. Every time it moves, little ridges form on your fingers, these are what make fingerprints unique. Just like no two clay sculptures are the same, no two people have exactly the same fingerprint pattern.
Examples
- A baby’s fingerprints might look a little wobbly at first, but they get clearer as they grow up.
- Your brother and you have similar fingerprints because you share some of the same genes.
- Even your left hand has slightly different fingerprints than your right one.
