Answer 1

There is an ongoing debate about why our bodies have developed this ability to wrinkle the skin. Wrinkling funnels water away from the skin. The most recently proposed theory is that skin wrinkling gives you a better ability to grip objects with wet fingers.6 By creating "treads" similar to tire treads, wrinkled fingers can grasp wet objects better.

And researchers suggest that the rest of the body does not wrinkle when immersed in water since hands and feet are the only areas of your body that grip,

This is one recent theory, and it certainly has a lot of people thinking they've solved the mystery of wrinkled fingers and ties. But this isn't the first theory proposed to explain finger wrinkling—and it may not be the last.
