Wrinkly bath fingers may be evolution's way of boosting grip

LOUNGING in the bath for too long has its benefits, according to scientists.

Parents tell children to avoid sitting in the bath too long, but researchers from Newcastle University suggest it could serve an evolutionary purpose.

Wrinkly fingertips help us to grab hold of wet objects much in the same way as the grip on car tyres, they said.

The study involved asking volunteers to pick up wet marbles before and after soaking their hands in warm water for 30 minutes.

Dr Tom Smulders, the author of the paper published in 'Biology Letters', said: "Going back in time, this wrinkling of our fingers in wet conditions could have helped with gathering food or vegetation from streams." (© Daily Telegraph, London)
