He then overcame a series of obstacles and faced off against a monster that had terrorised his community.

Its enduring appeal has puzzled researchers for nearly as long. However, in recent years, the study of storytelling has been revitalised, as linguists, psychologists and experts in cultural evolution have begun probing the subject using large databases of myths and folktales, powerful algorithms and an evolutionary mindset. We are finally starting to get answers to key questions, including what makes a good story, why some are more enduring than others and exactly how far back we can trace the roots of the most popular ones as well as how stories have traversed time and space.It is an epic quest, but there has never been a better time to undertake it.

Social media is almost a natural experiment in storytelling that, through its very platform, does the collection, says folklorist and ethnographer Timothy Tangherlini at the University of California, Berkeley.
