Fairy tales are old

When it comes to the origin of Western fairy tales, the 19th century Brothers Grimm get a lot of the credit. But a new study, which treats these fables like an evolving species, found that some may have originated as long as 6000 years ago. https://t.co/ogcv5i5IGB

From the article:

Here’s how it worked: Fairy tales are transmitted through language, and the shoots and branches of the Indo-European language tree are well-defined, so the scientists could trace a tale’s history back up the tree—and thus back in time. If both Slavic languages and Celtic languages had a version of Jack and the Beanstalk (and the analysis revealed they might), for example, chances are the story can be traced back to the “last common ancestor.” That would be the Proto-Western-Indo-Europeans from whom both lineages split at least 6800 years ago. The approach mirrors how an evolutionary biologist might conclude that two species came from a common ancestor if their genes both contain the same mutation not found in other modern animals.

But it’s not quite so simple. Unlike genes, which are almost exclusively transmitted “vertically”—from parent to offspring—fairy tales can also spread horizontally when one culture intermingles with another. Accordingly, much of the authors’ study focuses on recognizing and removing tales that seem to have spread horizontally. When the pruning was done, the team was left with a total of 76 fairy tales.

This approach allowed the researchers to trace certain tales, such as The Smith and the Devil, which tells the story of a blacksmith who makes a deal with the devil in exchange for unmatched smithing prowess, back thousands of years—all the way to the Proto-Indo-European people. If the analysis is correct, it would mean the oldest fairy tales still in circulation today are between 2500 and 6000 years old. Other stories seem to be much younger, appearing for the first time in more modern branches of the language tree.
