I think the lesson to be taken here is that religious and cultural traditions are not necessarily the most reliable sources from which to trace the ancestry of various tribes of people. For example, Jewish tradition taught that Ham, the son of Noah, whom Noah cursed for "seeing his father's nakedness", was the ancestor of the Canaanites, and the Jews used that belief as justification for the enslavement of the Canaanites by the Israelites. Later and for many centuries, Jewish, Christian and Muslim theologians identified Ham's descendants as the Black race, and - again - justified and explained that race's enslavement by citing the supposed connection.
