> 4. While the cake is in the oven draw some language trees. These indicate how populations have historically come into contact over time (population dispersal and the diversification of linguistic lineages). Seems superfluous; there are cases where we know good and well that a story was transmitted without much in the way of cultural contact. For example, Cinderella comes from China: https://en.wikipedia.org/wiki/Ye_Xian https://en.wikipedia.org/wiki/Ye_Xian We don't know anything about the path of transmission or the intermediate stories that must have existed in locations between China and Italy, but it is plain that the stories are the same.
