Did you know that every human being in this world has a unique fingerprint?
Even in the case of identical twins, their features might be identical in many things but they would never have matching fingerprints
Fingerprint patterns of a baby are considered to be set between 13 or 19 weeks of the development of the fetus
The inner layer of the skin starts developing rapidly while the outer layer of the skin develops slower than the inner layer
Due to this reason, the inner layer of the skin starts developing folds. Each human has different folds depending on how fast the inner and outer layer of their skin grows
It is at this time that the unique fingerprint of the baby has been set for life. Even if you get bruises on your fingers
You will notice that your skin will have the same fingerprints after your skin heals from the bruises. This is because when new skin grows in your body
It will follow the same patterns and folds set during your development as a fetus. This is why the fingerprints of people never change throughout their lifetime
