Fingerprints are not common in nature. They are generally only available to humans and primates such as chimpanzees and gorillas that are close to humans.
But there is a non-primate that not only has fingerprints, but its fingerprints are almost identical to human fingerprints, and even difficult to distinguish with high-resolution microscopes. This kind of animal is a koala, commonly known as koala.
The fingerprints of future crimes are not necessarily human, but may also be koala. Hahahahaha
