To understand how fingerprints are unique, you must first understand how fingerprints are created.

Although scientist are not exactly sure how fingerprints are formed, there is a popular theory among scientist about their origins.


In the womb, a mother has a layer of skin called the basal layer that is crutched up. The child in the womb gets skin creases because of this basal layer. This creates a unique fingerprint because the child will be in different positions in the womb and will therefore develop different creases on the skin. (Brit, Lasting Impression…)
