Human fingers shrivel during prolonged contact with water

Human fingers shrivel with prolonged contact with water for a reason: this mechanism is developed in the course of evolution to better keep wet and slippery predmety.

A team led by evolutionary biologist Tom Smaldersa (Tom Smulders) showed that people with wrinkled fingers better controlled soaked items, while working with the dry objects, this effect is not vliyaet.

Many people believe that the appearance of wrinkles on the finger pads after prolonged contact with water is called "slaking" of the upper layers of the skin, which swell, soaked with water. However, scientists have known that this effect does not appear when certain nerve damage in the fingers of man. It is caused by constriction of blood vessels and nervous system is controlled. In 2011, it was suggested that the active mechanism was developed during evolyutsii.

Group Smaldersa demonstrated one of the possible reasons for the formation of this mechanism. It is known that shrinkage of the fingers in contact with water appears in humans and chimpanzees. But it is possible that we - not only species, to develop this ability in the course of evolution.
