Unique Finger Wrinkling Patterns Could Aid Identification

When your fingers are in water, they wrinkle.

Scientists have discovered that these wrinkle patterns are unique to each person, just like fingerprints.

The wrinkles form because blood vessels in your fingertips shrink, causing the skin to contract.

Researchers found the patterns remain consistent over time.

This could help identify people, especially in situations where fingerprints are difficult to use, like after a disaster.

Further study of these patterns could potentially lead to new ways of identifying people.
