Many Native American folk tales there are suggest a similar form of exogamy, where daughters leave the tribe to find a partner and new community to be a part of. What effect would this kind of exogamy have? It might lead to a fair standardisation of the domestic arts, since women "from everywhere" came together in each tribe and could compare and adopt methods. Whereas, the arts of the hunt and the art of war might remain fairly distinct in each tribe.
