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.
