One of these days, science tells us, people won’t need teeth, they’ll grow pufferfish-like beaks instead. At least that’s what a biologist at Sheffield University believes. According to Dr Gareth Fraser, humans might just evolve to grow beaks — not unlike the ones sported by pufferfish — which are ‘far more robust and practical.’ How long will we take to get there? He conceded that it might ‘take a while’ though. Science fiction belongs in the far future.
