Fingerprints begin to form in the tenth week of pregnancy. This process of fingerprint creation occurs in the basal layer of the womb. The basal layer is the layer in which new cells are produced for the fetus. To create the fingerprints, the basal layer crumples and folds in different directions. This is what creates the different shapes in everyone’s fingerprints. In addition, in this process, an outer layer of skin is formed to protect the fingerprints.

The Niles North Viking and the Glenbrook North Spartan each have a single finger with the arch ridge pattern. We found
