Original Message Humans could one day evolve beaks, a biologist has suggested.

Dr Gareth Fraser, from Sheffield University, said the process could see teeth fuse together to form a bill over millions of years.

A beak would be “more robust and practical” than teeth, and less susceptible to wear and tear.

Dr Fraser told the Daily Mail: “It could be possible for humans to evolve to grow beaks, like pufferfish, which may be more robust and practical."

The biologist has also investigated why humans only get two sets of teeth a lifetime, while other animals - like sharks - get lots of new sets.
