One similar phenomenon, known as a von Karman vortex, occurs when currents of air or liquid move in opposite directions. The process can create fantastically curled clouds. Insects borrow energy from von Karman vortices created by their own wings to improve speed and maneuverability.
The diverse patterns are not all created by the same mechanism, K? That similarity makes it very difficult to locate the physical mechanism behind each, especially with highly complex biological patterns. Although our model, as it is, does not have any direct implications for fingerprint identification it could help to provide a more solid foundation of the subject in the future.
Live Science. But the seasonal pattern was wiped out in people exposed to the famine, they found. This suggests that environmental factors must play a role. Maternal stress hormones? By Alison Motluk Fingerprints may provide important clues about life in the womb, and may even become useful as predictors of disease risk.

Curious Kids is a series for children of all ages. How do we get the fingerprints we have? Fingerprints are those little ridges on the tips of your fingers. Your fingerprints began to form before you were born. When a fetus starts to grow, the outside layer of its skin is smooth. The expanding lower layer ends up scrunched and bunched beneath the outside layer. These folds eventually cause the surface layers of the skin to fold too, and by the time a fetus is 17 weeks old — about halfway through a pregnancy — its fingerprints are set.
Although this folding process might sound random, the overall size and shape of fingerprints are influenced by the genes you get from your parents. So you probably share some fingerprint patterns with your family members.
