SCIENTISTS believe that humans may eventually evolve to have beaks rather than teeth.

The bizarre theory has been put forward as part of a study looking into how fish grow teeth throughout their lives to help humans do the same.

Researchers at Sheffield University came to this hypothesis after looking at the jaws of pufferfish, which over millions of years have formed into beaks.

They were able to isolate the cells responsible for enabling fish to create an endless supply of teeth.

This should help create dentistry techniques that allow humans to do the same – although it is estimated the technique is at least 50 years away from fruition.
