How is a fable part of an oral tradition

Fables originally were part of oral tradition because they were originally told in tribes that did not have a formal writing system 

The native americans, spanish, french and americans all name places in our state. the word “arkansas” came from the quapaw indians, by way of early french explorers. at the time of the early french exploration, a tribe of indians, the quapaws, lived west of the mississippi and north of the arkansas river.
