Why is it EBA Jordan sample has significant Anatolian but the Semitic speakers of both Arabia and Northern Ethiopia/Eritrea either completely lack it or carry it under 10%?

Because they are different people.

They are sure different populations sparsed by space and time that's why. From a common Levant BA source, they've diverged.

That Levantine source is like 20% Anatolian while some groups in Arabia either have it in very low percentage or don't carry it all like the Mahra.What has caused the Arabs to lose their Anatolian admixture? Is it possible there was indigenous Natufian rich populations that lived in Arabia or is it possible the ancestors of these Arabians prior to migrating into the Peninsula never carried Anatolian ancestry?

I modeled Bedouins in Global25 as 70% Natufian, 10% Anatolian farmer and 20% Iranian farmer. The Anatolian farmer percentage is still much lower than that of Levantine Arabs but higher than in your model. I believe that Arabia was settled early by Levantines and received much less Anatolian, Iranian and Caucasian influence.

Perhaps the Arabian Peninsula was inhabited by pure Natufian-like people.

hello,

what is the difference between Arabian and middle eastern?

Arabic are Semitic.

Arabians descend from some sort of early population of Levantines which existed prior to the intrusion of ANF and Iran_N ancestry into the Levant.

Well genetically, Peninsular Arabs and Levantines are different even if they speak a common language. And even then they're different dialects.

The Levantines themselves became Anatolian enriched in the first instance at least by the PPNB period. There isn't any published Levantine PPNA DNA that I know of, so IDK if they arrived in the PPNA. But it looks like the Anatolian ancestry, or at least the first iteration of it arrived between the Natufian and PPNB period. This wave probably didn't make it to Arabia itself, and the Anatolian ancestry might have been dispersed into Arabia later on indirectly. There isn't a long ancient DNA record from Arabia, so again, it is hard to tell when and how the small amount of Anatolian ancestry in Gulf Arabs arrived, but it definitely is a lot lower than the amount found in the Levant.
One interesting observation is the higher frequency of lactose tolerance in Arabian-proper populations than in Levantine populations. This could be indicative of a difference in selection pressures due to the different neolithic subsistence strategies. Maybe a group managed to successfully set up its own alternative to the PPNB cultures of the Levant involving a heavier focus on pastoralism, or maybe instead the Arabian groups inherited aspects of the PPNB tradition (along with minor admixture) which they shaped into a more pastoralist heavy tradition.

PS: A more stark contrast between Levantines and Arabians emerges if you use Barcin neolithic instead of copper age, since iirc, the copper age has more Iranian admixture.

Oddly enough groups like Yemenite Amran,Yemenite Jews and on average most of those Yemeni samples except the Mahra are a lot more Barcin admixed than the Saudi & BedouinB samples.The Amran samples are clearly the most Levantine shifted Arabians on G25

Arabs first appeared in the Levant as mercenaries for the Egyptians, first recorded as being captured by the Assyrians ...............it would appear, as you say , there is a stark contrast between Levant people and Arabs

How do you think that came to be? I don't know about the history and prehistory of Yemen specifically so I don't know. So I did what someone else who knew more about Yemen probably wouldn't do and ran Yemenites as a mix of Saudis and Fars Iranians. Amran is indeed the most Iranian-shifted, but IDK if there is any actual Iranian ancestry in them or if this is simply an indication of Amran having more of the Anatolian-enriched ancestry than others, for which Fars is simply a stand-in/proxy (at least a closer one than the Saudi input).

Whatever the case is, you are right about Mahra being the most similar Yeminites to Saudis and Amran being the most different.

Anatolian N groups were attracted to agricultural regions it seems. West/North Yemen has the most agricultural lands in Arabia. Mahra region is quite dry and far from these farming areas.

The spread of Anatolian genes was largely due to farming. The fertile crescent is fertile after all. The people of the Arabian peninsula were pastoralists and traders.

It's likely, according to many, that Natufian-like peoples inhabited Arabia since the paleolithic, and that Levant_BA (from the southern Levant that is, to explain their lesser Anatolian ancestry) admixture was introduced by Levantine nomads like the Amorites and Arabs during the middle and late Bronze Age respectively.

On the contrary it’s actually interesting to me how much ANF and Iran_N there is in Arabia as those two ancestries are associated with farming and Arabia being a desert.

Nah it seems only the Yemenis excluding the Mahra samples are the only heavily ANF Arabian samples.The Saudis,Mahra and majority of the BedouinB have very low levels of it.The Amran samples interest me as they are the Arabian samples with the most Barcin ancestry,don't know why tho.It also seems the Ethio-Semitic ancestors of the Habesha generally probably had low to non-existent Barcin ancestry

I stand corrected. They score a fairly decent amount of Iran_N though so its still shocking.
