‘Teeth no longer fit, Humans may grow beaks’

Jul 06, 2013 |

The big beak theory! Humans may eventually evolve to have beaks because our teeth are “no longer fit for purpose”, a biologist has suggested.

Scientists have argued that with our modern diets and growing elderly population, a limited amount of teeth is hampering us as a species and the current structure of human teeth cannot suffice. Researchers at the University of Sheffield have been exploring theories as to how evolution might resolve this problem. One way human beings might be able to avoid the dentist is to develop beaks, TheInformationDaily.Com reported.
Scientists have been examining the jaws of the pufferfish, which has evolved over millions of years to form a beak. Pufferfish use these to break open the shells of molluscs and crabs.
Beaks are more “robust and practical”, according to Dr Gareth Fraser, lead researcher.
