Do Arabians have very minor Steppe ancestry?

[Zoro]

Before this, I thought native Peninsular Arabs including Saudis and Yemenis would be the one of the only West Asian-North African group besides Samaritans, Georgians (surprisingly despite their close geographical proximity to the Pontic Caspian Steppe), Trabzon Turks, Hemsheni Armenians and Egyptians to have negligible noise level to literally zero steppe.

Impossible. There’s a 0% chance that Armenians, Georgians, and Trabazon Turks have been totally isolated from their neighbors for the last 4000 years. You would need a ton of evidence to show that these populations haven’t mixed with their neighbors. G25 certainly doesn’t qualify as such.

Also remember that Saudis of today are not the Saudis of 3000 years ago. Oil has done wonders in attracting people from Central, South and West Asia into Arabia over the past 100 years. This has introduced all sorts of non native haplogroups and admixture into the Saudi gene pool.

R1a in West Asia is the highest among Bedouin in Kuwait more than 40% its higher than Iran.

https://en.wikipedia.org/wiki/Haplogroup_R1a#Asia

R1a1a has been found in various forms, in most parts of Western Asia, in widely varying concentrations, from almost no presence in areas such as Jordan, to much higher levels in parts of Kuwait and Iran. The Shimar (Shammar) Bedouin tribe in Kuwait show the highest frequency in the Middle East at 43%.

Wells 2001, noted that in the western part of the country, Iranians show low R1a1a levels, while males of eastern parts of Iran carried up to 35% R1a1a. Nasidze et al. 2004 found R1a1a in approximately 20% of Iranian males from the cities of Tehran and Isfahan. Regueiro 2006 in a study of Iran, noted much higher frequencies in the south than the north.

Kuwaitis have mixed with Arabs who have mixed with Bakoch and S. Asians not to mention Persians

Well some Yemeni Amran, Dhamar and Jew individuals were scoring in the 5-7% range which is pretty significant for the region. That's average Lebanese Christian level of steppe. You are right regarding the geographical proximity of Arabia to neighboring regions.

The problem seems to lie with the fact that you are using simulations. There are already legitimate samples for Natufians and ANA(Taforalt is Iberomaurisian which contains ANA). You don't need to make simulations for those. The problem with G25 simulations is that while they can help bring a better fit, they are usually imperfect and create weird shifts in certain directions. In thise case it's probably causing the Yemenites to take in steppe when they otherwise shouldn't(or only a noise level). Let me demonstrate with proper samples:

I thought the reason for these simulations is to estimate the amount of ANA admixture in Natufians and Taforalt by separating them from the two components? Btw I got these simulations from here. Many people have also been using them on Anthrogenica to measure the amount of ANA blood in these ancients.

Doesn't Levant_Natufian hide the African blood (ANA) in Yemenis and other Arabians? That's why I think using these simulations are better. I feel like Natufian is absorbing additional SSA ancestry in Yemenis and Saudis since Natufian is Iberomaurusian (which contains ANA which is African) + Anatolian_N from what I learnt in Anthrogenica. They tend to score SSA/Negroid in older calculators. If I don't use the simulators, this is what I get:

Anyway it looks Yemenites from Amran are the most Northern-shifted (Steppe) even if there IE blood is very tiny level. So I believe you are right. Other groups that literally noise to completely lack Steppe in the MENA region are Western Georgians, Samaritans, Hemsheni Armenians, Trabzon Turks and Egyptians?

Yes, that is a valid reason that someone might want to break Natufian and Iberomarusian up, that is to separate the west asian and SSA components within those two. However, there is always a drawback with the simulations. I don't believe steppe ancestry reached Arabia aside from the Khaleej(Gulf) where the people came into contact with Persians and South Asians, and even then it's probably quite minor.

Not entirely sure about Egyptians but most of those groups that you mentioned while lacking proper Indo-Iranian ancestry still have a lot of ANE so they're not comparable to say Yemenites and Samaritans who are very ANE depressed.

Seems like most Yemenis and other Peninsular Arabs do have Negroid (mainly Dinka) even if it is very minor. When using those simulated coordinates though, it looks like they also have a second layer of African blood that is ANA besides the Nilo-Saharan (or in some cases Bantu) admixture.

I see. I did some runs on Egyptians and they seem to have very minor IE, its less than Maghrebis and Levantines but more than most Arabs of the Peninsula. True those groups still have loads of ANE. Do you why Samaritans seem to have noise to literally lacking Steppe unlike most Levantines? Endogamy and refusal to intermarry with invading Greeks, Persians, Assyrians and other outsiders in the Levant?

I see. I did some runs on Egyptians and they seem to have very minor IE, its less than Maghrebis and Levantines but more than most Arabs of the Peninsula. True those groups still have loads of ANE. Do you why Samaritans seem to have noise to literally lacking Steppe unlike most Levantines? Endogamy and refusal to intermarry with invading Greeks, Persians, Assyrians and other outsiders in the Levant?

Yes. They are endogamous relic pop

I heard they are purest locals and closest to Bronze Age Levantines like Sidon_MBA. Ancient Israelites,Judeans and Canaanites must be genetically identical to Samaritans. I have seen many models where Samaritans can be model as whopping 90-95%+ Bronze Age Levantine such as Sidon_MBA, Hazor, Megiddo_MLBA! The genetic continuity is amazing and insane. Not even Lebanese and Palestinian Christians are that autochthonous.

I notice Yemenis from Amran have slightly more Steppe affinity than other Peninsular Arabs even if its at negligible levels. Run some models on them and it seems they have substantial Levantine-like admixture compared to other Arabian inhabitants.

And it looks like the SSA blood in Yemenis, Saudis and other Arabians come from Cushitic/Horner ancestry?
