kinda neat how arabians originally probably came in large part from natufians. so the palestinians and hashemite jordanians can say that even if (at least some of) their ancestors were in arabia for thousands of years, they began in the Levant (after Africa obvi). however this was practically prehistoric. honestly if you go far back enough pretty much every claim to roots in a place winds up leading to some other place. this is especially true for the near east, fertile crescent, and mediterrainian. I think what matters more than anything is whether your culture is indigenous and unique to a place and not found other places, whether you first became the group you consider yourself to be there, and whether you regard the land as very important to your being. while it could be said that indigenous Hawaiians were somewhat recently Polynesians, they have a unique culture to Hawaii, became Hawaiians in Hawaii, and revere their land, so it doesnt matter. existence precedes essence here and everywhere, a group can use genetic studies all they want but if they dont have a significant common experience of standing out at least somewhat from other groups due to their particularities and also of remembering shared treasured stories of their people and land, what's the point?
