A priceless piece of art has been stolen from a museum and detectives are called in to in vestigate the crime. The thieves were very clever-they avoided the securith cameras,guards and laser beams and their getaway car was never found. Hoever, they left behind an important clue: a single perfect fingerprint. For a quick-witted detective, this is more than enough information to solve the crime.
Our fingerprints are very special. You might have the same eye colour as someone else and the same shaped nose. If you are an identical twin, you might even have a face that looks the same, but not single person on earth has fingerprints identical to yours.
Fingerprints are the patterns on the pads of your fingers made by tiny ridges in the in outer layer of your skin called the epidermis. These ridges haip you get a better grip on smoothe things. This is particularly importent when you are climbing trees and swinging from branches. All primates, all primates, including monkeys and apes have fingerprints.
