Fingerprints: Records from the Womb

Have you ever wondered how our fingerprints develop and how everyone has a unique pattern?

During the third and fourth months of gestation, the fetus's skin begins to transform from thin and translucent to thicker and waxy. At this time, the middle layer of skin outgrows the inner layer and this contributes to the buckling and folding patterns we see on the fingertips.

Further, by touching the surrounding structures within the womb, and depending upon baby's position, activity level and density of the amniotic fluid this will determine how every individual ridge forms.

Our fingerprints are a record of our womb conditions during this developmental time and are said to even be linked to a higher predisposition for diabetes later in life (more ridge patterns).
