you could say its something more but thats a question of belief. most of these cultures will tell you eventually they have learnt it either from ancestors or from spirits / god. that being nothing which can be proven by the scientific method, for science, it's nothing more, and if thats what you believe, cultural knowledge and trial and error is all that remains as a possibility.

lots of cultures carry knowledge which is 'strange' for them to have or carry. how they came about it is often a mystery at best.
