Why fairy tales are really scary tales

Some people think that fairy tales are just stories to amuse children, but their universal and enduring appeal may be due to more serious reasons

People of every culture tell each other fairy tales but the same story often takes a variety of forms in different parts of the world. In the story of Little Red Riding Hood that European children are familiar with, a young girl on the way to see her grandmother meets a wolf and tells him where she is going. The wolf runs on ahead and disposes of the grandmother, then gets into bed dressed in the grandmother’s clothes to wait for Little Red Riding Hood. You may think you know the story – but which version? In some versions, the wolf swallows up the grandmother, while in others it locks her in a cupboard. In some stories Red Riding Hood gets the better of the wolf on her own, while in others a hunter or a woodcutter hears her cries and comes to her rescue.

The universal appeal of these tales is frequently attributed to the idea that they contain cautionary messages: in the case of Little Red Riding Hood, to listen to your mother, and avoid talking to strangers. ‘It might be what we find interesting about this story is that it’s got this survival-relevant information in it,’ says anthropologist Jamie Tehrani at Durham University in the UK. But his research suggests otherwise. ‘We have this huge gap in our knowledge about the history and prehistory of storytelling, despite the fact that we know this genre is an incredibly ancient one,’ he says. That hasn’t stopped anthropologists, folklorists* and other academics devising theories to explain the importance of fairy tales in human society. Now Tehrani has found a way to test these ideas, borrowing a technique from evolutionary biologists.

To work out the evolutionary history, development and relationships among groups of organisms, biologists compare the characteristics of living species in a process called ‘phylogenetic analysis’. Tehrani has used the same approach to compare related versions of fairy tales to discover how they have evolved and which elements have survived longest.

Tehrani’s analysis focused on Little Red Riding Hood in its many forms, which include another Western fairy tale known as The Wolf and the Kids. Checking for variants of these two tales and similar stories from Africa, East Asia and other regions, he ended up with 58 stories recorded from oral traditions. Once his phylogenetic analysis had established that they were indeed related, he used the same methods to explore how they have developed and altered over time.
