Fingerprints

Everyone in the world has different fingerprints, yes including identical twins.
Fingerprints can indentify people in a crime. But not many people know that everyones ears are also different except indentical twins!
Alot of people think fingerprints are only used for crime identification, but if we didnt have the ridges or loops on our fingers we wouldnt be able to grip things as there would be no friction.

There are nine patterens of fingerprints recgonised by the FBI:-

Right Pocket Loop
Left Pocket Loop
Arch
Whorl
Mixed Figure
Left Loop
Right Loop
Double Loop
Tentarch



But remember everyones fingerprints are different!
