Rat or frog? TikTok theory claims everyone looks like one or the other - and now scientists say there may be some truth to it

Do you have more rat-like features, or do you resemble a frog? According to a theory circling on TikTok, everyone looks more like one animal or the other.'Everyone either look likes a frog or a rat, no one can ever change my mind,' one user explained. Another joked: 'When you realise the rat and frog theory is too real and categorise every person that walks past as a rat or a frog.'So, is there any science to back up the theory? According to Dr Julian De Silva, a facial cosmetic surgeon based on London's Harley Street, the answer is yes. Speaking to the Daily Mail, he explained: 'There is more science in it than people think. 'The trend is really a simple way of describing facial proportion, and is exactly what facial plastic surgeons evaluate. I divide faces into seven shapes, and they fall neatly into two camps.' Do you have more rat-like features, or do you resemble a frog? According to a theory circling on TikTok, everyone looks more like one animal or the other 'Rats' cover people with diamond, heart, and oblong faces. 'Frogs' cover those with round, square and pear shaped faces. One exception to the rule is Rihanna, who sits in the middle, Dr De Silva saysAccording to Dr De Silva, 'rats' have long, narrow faces that come to a point, with high cheekbones, a slim jaw and chin, and features that project forwards. 'That covers the diamond (Megan Fox), the heart (Scarlett Johansson and Reese Witherspoon) and the long, oblong face (Gisele Bündchen and Victoria Beckham),' he said. In contrast, 'frogs' have wide faces, with their eyes further apart, a broader mouth, and a strong jaw. The surgeon said: 'That covers the round face (Kate Moss), the square face (Angelina Jolie, Keira Knightley and David Beckham) and the pear shape, where the jaw is wider than the forehead.'One exception to the rule is Rihanna, who sits in the middle, Dr De Silva says. He added: 'Rihanna's oval face sits right in the middle, and that balance is one reason it photographs so well.' On TikTok, several users have suggested that couples tend to consist of one rat and one frogIn his clinic, Dr De Silva says that rat faces are more sought-after amongst women. Meanwhile, men tend to seek out more froggy features. He said: 'The diamond face is the shape women most often ask me for: high cheekbones, a slim face and a narrow jaw and chin. 'The heart shape is close behind, and men most often want the strong square jaw of a frog like David Beckham.'However, if you're a woman with a frog face or a man with a rat face, don't panic. Dr De Silva reassures that there is 'no single template for beauty'. 'Wide frog faces often age beautifully, because strong cheekbones and a broad jaw give the soft tissue more to rest on,' he said. Dr De Silva says the Beckhams are a classic example of a couple consisting of a frog (David) and a rat (Victoria)'And Gisele, with a long face the old textbooks called a flaw, became the highest paid model in the world.'On TikTok, several users have suggested that couples tend to consist of one rat and one frog. As an example of this, Dr De Silva highlights the Beckhams. 'David has a classic square frog face and Victoria a long, narrow rat face,' he said.'Opposites balance each other in a photograph, and I suspect that is part of why they have looked so good together for nearly thirty years.'However, the surgeon points out that several studies also suggest that many people are drawn to faces like their own. He added: 'Plenty of rats marry rats.'
