Fingerprints are like little patterns on our fingers that help us grab things. They're made of tiny bumps and lines, and they’re different for everyone! Scientists think these patterns might have helped humans hang on to trees when we were still climbing around a lot. It’s kind of like having little grips built into your hands.
Examples
- A baby learns to hold onto their mother’s finger as they begin to explore the world.
- A monkey uses its fingerprints to grip branches while swinging through the trees.
- Your thumb leaves an imprint on your phone screen, like a tiny fingerprint signature.
