- Folktale transmission in the arctic provides evidence for high bandwidth social learning among hunter–gatherer groupsRoss, Robert M. - Evolution and Human Behavior, 2016 - 4 Hypotheses
The myths, legends, and folktales of nearby groups tend to more alike than those of more distant groups. Three competing models attempt to explain this distribution of cultural traits: (1) vertical transmission, (2) horizontal transmission, and (3) independent innovation. The authors examine 18 Arctic hunter-gatherer groups to quantify the extent to which geographic distance, cultural ancestry, and effective population size predict overlap in folktale inventories.
