Are J1 and J2 originally from CHG?

[luc2112]

Ottoman Empire originated in Northwest Anatolia, not Arabian peninsula

Caucasus Hunter Gatherers migrated to Arabian peninsula and carried J haplogroup there

North Africa is predominantly Natufian by male lineage

Is likely, but the Arab empire began in the Arabian peninsula

Arab Caliphate is not Ottoman Empire

Ottoman Empire originated in Northwest Anatolia, not Arabian peninsula

Caucasus Hunter Gatherer admixture is not minor among Arabians and J1 might have come there via CHG males

North Africa is predominantly Natufian (ghost population which is heavily related with Semites and Arabs) by male lineage (Y-DNA)

Its still not clear where J2 originated but ancient J2a samples found in Siberia and Altai region doesnt have any autosomal link with near-east. J2 is a bit complicated stuff. Many ancient samples found in Central and south-asia and also in parts of Europe that belongs to J2. Another crazy thing is the fact that many Uyghurs in Xinjiang belongs to haplogroup J2a. Around 30% of x people tested.

As far i know J1 = arab.

CHG is most probably responsible for J presence in the rest of Western Asia. CHG used to be very widespread in East Med area that even Egyptians have 3/10 CHG admixture

J1 might not originally Arabian because admixture patterns of both J1 and J2 look so much like CHG admixture pattern. Therefore, both might be from CHG in my opinion

yes it is correct, its origins are not known, but what is considered Indo-European are linguistic roots. Slavs are Indo-European, but not necessarily Caucasian.

all middle-eastern arabs are CHG admixed.. Maybe proto-afroasiatic speakers were a more northafrican or even eastafrican like population.
But yes i would consider J1 and J2 caucasian.

J is unrealated with Eurasian R and Q and close relative of haplogroup I, both originated in Iranian highlands based on clade diversity and TMRCA. But J2 presence among early Turkics is pretty much sure, they probably were assimilated during their ethnogensis hence modern and ancient presence all over Eurasia. Nevertheless, it's deepest origin is CHG.

J1 is not simply Arab, that is very superficial pow based on facts it is dominant among them today. Based on clade diversity and relatively low TMRCA of main semific clades it looks to be Caucasian lineage that spread south into Levant and Mesopotamia, later to Arabian peninsula. So yes, J1 took part in creation of early Arabs similary like J2 did in creation of early Turks, but none of these markers are their most original ones. Autosomal CHG admixture in Semites comes from these J1 men (and J2 in minor part)..

Yes but by who? As far as I know, there have been no groups or cultures that have influenced the Turks. Who were the carriers of J2a to the Turks? As i remember Karluks and Karakhanids were largely J2a. Perhaps thats why the present Uyghurs has such high frequencies of J2a. But the main question still remains. Who carried J2a to them.
