A quantitative study, published by folklorist Sara Graça da Silva and anthropologist Jamshid J. Tehrani in 2016, tried to evaluate the time of emergence for the "Tales of Magic" (ATU 300–ATU 749), based on a phylogenetic model] They found four of them to belong to the Proto-Indo-European (PIE) stratum of magic tales, namely:
ATU 328 The Boy Steals Ogre's Treasure,
ATU 330 The Smith and the Devil (= KHM 81a),
ATU 402 The Animal Bride (= KHM 63 and 106), and
ATU 554 The Grateful Animals (= The White Snake, KHM 17, and The Queen Bee, KHM 62).
