Summary

The likelihood of two people sharing identical fingerprints by chance is estimated to be less than one in64 billion. Even identical twins – who have the same DNA sequence and tend to share a very similar appearance – have slightly different fingerprints. That’s because fingerprints are influenced by both genetic and environmental factors during development in the womb.

A new study shows that humans and animals have similar fingerprints. The study was published in the journal Evolution and Human Behavior. The findings were published by the journal Science.

It's almost like how we generate random was for computers, where ambient noise and signals affect what gets output!
