Embryos develop fingerprints at 3 months, and are unique based on movement, location in the womb and composition of the mother’s amniotic fluid. Fingerprints are made of several layers of twisted skin that formed prior to birth. These ridges of skin make three main patterns - loops, whorls, and arches. The raised skin patterns on our fingertips and palms allow us to grip and hold onto things. Without them, things would slide right out of your hands!
Even if your fingerprints are damaged, they will grow back in the same unique pattern. No one has the exact same fingerprint!
Adermatoglyphia is a disease where people are born without fingerprints. It is exceedingly rare, affecting only four known extended families worldwide.
Fingerprints can now be evidence of drug use. A handheld device uses a gold nanoparticle solution which sticks to the breakdown products of drugs as they sweat out through the pores in the fingertips. The particles are stained with a fluorescent dye which leaves a pattern.
Identical twins are indistinguishable via DNA testing, but fingerprints can still tell them apart.
As people get older, the one thing that does not change is their fingerprint pattern. Your fingerprints stay the same for your whole life.
