Durable as well, even when fingerprints have been damaged or worn, they can usually replace themselves. Here’s how. • Fingerprint formation • Although scientists agree that fingerprints begin to develop around the 10th week and are complete by the end of the 4th month, no one is certain of the precise process that creates them. • One theory holds that a middle skin layer, called the basal layer, is scrunched between the inside layer (the dermis) and the outer skin layer (the epidermis). As the faster-growing basal layer strains against its neighbors, the pressure causes the skin to buckle, forming “folds of the epidermis into the dermis,” and resulting in the complex patterns we see on our fingers today. Nerves are said to play a part in this process as well, as they are hypothesized to be the origin of the “forces that pull in the epidermis.” • Interestingly, it is precisely because the pattern is “encoded at the interface between the dermis and epidermis,” that it becomes nearly permanent and “cannot be destroyed by superficial skin injuries.” • Background. music credit : • Happy Explainer by Michael Musco: / m. . • Attribution-NoDerivs 3.0 Unported (CC BY-ND 3.0) • https://creativecommons.org/licenses/... • Music provided by Free Vibes: https://goo.gl/NkGhTg
