Using techniques normally employed by biologists, academics studied links between stories from around the world and found some had prehistoric roots.
They found some tales were older than the earliest literary records, with one dating back to the Bronze Age.
The stories had been thought to date back to the 16th and 17th Centuries.
Durham University anthropologist Dr Jamie Tehrani, said Jack and the Beanstalk was rooted in a group of stories classified as The Boy Who Stole Ogre's Treasure, and could be traced back to when Eastern and Western Indo-European languages split more than 5,000 years ago.
Analysis showed Beauty And The Beast and Rumpelstiltskin to be about 4,000 years old.
And a folk tale called The Smith And The Devil, about a blacksmith selling his soul in a pact with the Devil in order to gain supernatural abilities, was estimated to go back 6,000 years to the Bronze Age.Science News also covers the paper, saying in part:
Tehrani and Sara Graça da Silva of the New University of Lisbon in Portugal studied 275 magic-based stories from a database of more than 2,000 types of folktales. Magic stories include beings or objects with supernatural powers and are the largest folktale group. Statistical analyses of the relationship between the folktales and language, as well as between the folktales and how they may have been shared by neighboring peoples, left the team with 76 stories that they thought were strong candidates for accurately estimating folktale age. Family trees, or phylogenies, of Indo-European languages throughout Asia and Europe helped the researchers investigate how the region’s language history related to these folktales.
