Why Finger Wrinkles When Wet?
Fingers become wrinkled when wet can be a form of adaptation so that we can hold more strongly in wet conditions. The hypothesis was stated Mark Changizi, an expert in evolutionary neurobiology 2AI Labs, in Boise, Idaho, United States.
The study results Changizi and colleagues published in the journal Brain, Behavior, and Evolution is contrary to general belief that the fingers become wrinkled as it absorbs water.
According Changizi, wrinkles on a wet finger function like grooves on a tire. Wrinkles form as a place to channel the flow of water when we press a fingertip on a wet surface. This is what causes the fingers grip on wet surfaces become more powerful.
Changizi and his team studied 28 photos fingers wrinkled due to water. The team found a common pattern in the observations of unconnected long canal which is a ramification of the above point the finger.
When we emphasize the finger, place the pressure from the fingertips to the back. In contrast to the side of the finger where the water can flow easily, the flat part of the finger-like plateau which is where water can stagnate.
Wrinkles are formed on the plains is because, "That's where the channel is formed to drain the water," said Changizi. He will test the hypothesis to see whether the person whose fingers were wrinkled may hold better in wet conditions.
