(The Independent) 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.”
