Question

【题目】 Everyone knows the strange feeling of your fingers wrinkling up (起皱) when they’re wet. Sometimes when in water, it seems as if your hands have aged 30 years in a second. But is this an accident? Or is it something that nature has built into our bodies?

Scientists at the University of Newcastle in the UK recently did a test. They asked people to pick up things (some wet and some dry). And take them from one place to another. Some people did this with dry hands, while others had to leave their hands in water for 30 minutes first so that their skin was wrinkled. The study found the second group with wet hands had an advantage when carrying things that were also wet.

The scientist Tom Smulders said that “this wrinkling of our fingers in wet conditions could have helped with gathering food from wet vegetation or streams. Wrinkling happens when blood vessels contract (血管收缩) and pull the skin back.

A long time ago, humans lived a very difficult life in a brutal world, where the smallest advantage could make a huge difference. Having wrinkled skin might have helped people catch fish. This would help them get through the winter. These humans would then have had an advantage. Their genes would be accepted by natural selection.
