The Arabs who have E-V32 (like most Daroods and Somalis do) are;
1) An extreme minority
2) Have a recent African ancestor and a considerable amount of East African autosomal DNA.
The more ridiculous claim of being Hashemite is further discredited by;
* The Hashemites of Hijaz/Jordan are all Haplogroup J1 (which was obvious).
The consequences of an E-V32 Somali which accounts for over 80% of Darods from every subclan on 23andme and other agencies, being a Hashemite would mean that Oromos, Afars, Masai, Tanzanians, Ugandese and others who carry E-V32 are just as likely to be a Hashemite (which is ridiculous).
Having said that, an E-V32 Darood/Isaaq (claimants of Hashemite ancestry) in fact share a closer ancestor to a West African Igbo than the Prophet peace be upon him (Fact).
Besides I am not sure if being arab is even a DNA after looking into in-depth, I think it's more a mind-set or culture or thinking, it's not even a language because the arabs of north africa and levant area are not really arabs at all and have inherited their thinking and culture from the previous civilization they come from, they are basically arabs who were taught the language kinda similar to a somali who learned english but he ain't adopting the thinking or culture of the west is he?
Real arab culture is in yemen and we can see in yemen tribes are black as coal in tihama and whiter in sanaa and brown or indian heritage types in aden, they don't even have a common language like south arabian language isn't really arabic but completely different to arabic, the only thing they share is 'lineage tracing' tribal ethics and code of conduct and basically sitting under a tree or in a room chewing qat and debating on tribal pride, history, proverbs, history. Being an arab isn't the palestinian or lebanese for god sakes, they still have the old culture they are from in them. They only speak the language and that's about it but do not trace their lineage or ancestors because their not really arabs nor do they think the same.
Notice how they set up their people on religious sects such as sunni and shia because that's how they recognize each other in palestine, iraq,syria and so forth? that's the only way they can form their society since tribe isn't a passion or factor since their not really descended from arabs nor have that thinking. An arab is a tribal nutcase and it's about counting generations for a long time and then being a poet or abwaan and a lover of camel and nomadic culture, he is basically a wanderer and explorer and travels under the protection of his tribe or their grazing lands.
Settled arabs in yemen are still tribal noticed? but go to settled arabs in the gulf and their exactly the same still but once u venture further into territories that adopted arab language because i don't say they adopted the culture or else they would be tribal so they adopted the language and you will see their not really arab at all and just speak the language.
Can we say this is any different to Somalia? we are arabs whether we like it or not, we think exactly like them but I mean the REAL arabs or why else you think they added us into the arab league for shits n giggles? being an arab is far from racial ground which is quite new thinking that developed in the 18th century, previous societies never really cared for your race but more so your lineage and if it was honorable and noble, that's why the romans viewed the world as barbarians and the rest as romans and civilized, they could care less what color, language you spoke as long as you had the same culture as them, people want people who are similar in thinking to them, haven't you noticed? that's why even if your from the same race and you don't think the same as the guy who is in the same race, you will see conflict.
Look at Africa for example, same race or color but constantly at war it's due to our thinking and culture being vastly different and the europeans who came to the continent with an 18th century system of race didn't care for our differences and just looked at our color, poor visions of creating a colonial system. You can also see this among arabs who never unite among themselves and constantly at war, it's cause the culture is different and priorities aren't the same, they don't think the same and only speak a common language.
Can people unite on an identity of language? I don't think so personally because a language doesn't shape your culture or thinking or else all the arab world would be similar to yemen culture today which is the closest thing to the prophet culture but I say Somalia is even closer to be quite honest.
