Is the SSA admixture in Arabians underestimated by G25?

[Zanzibar]

Asking because I'm surprised by how low the SSA the various Arabian populations are. In the older calculators like Eurogenes K8 or Eurasia K6 and PuntDNAL Global K13, Arabians like Yemenis, Saudis (BedouinA is Levantine Bedouin and seem genetically different from the former) score a lot more African ancestry according to the spreadsheets. In G25 from what I have observed, the Yemenis are only 1-5% African (mainly Dinka) at most, while Saudi and BedouinB barely have any SSA.

So I am wondering if the Natufian component is absorbing a lot of the African ancestry in Arabians or not? Also from what I learn, Natufian is Iberomaurusian (which contains ANA ancestry) + Anatolia_N, would most of additional African ancestry in Arabians be ANA/ANA-like?

However what's funny is if you remove the Natufian, the SSA increases lol even if the distance fit worsens a bit.

Btw here are the individual runs with Natufian included into the model:

BedouinB (BedouinA is Levantine and are genetically different so I didn't include them) and Saudis

Yemenites from Al Bayda, Al Jawf, Amran and Dhamar.

https://i.imgur.com/swG9pkP.png

Yemenite Jews, Yemenites from Ma'rib and ethnic Mahras

https://i.imgur.com/PSoHiD9.png

The most African admixed Yemeni individuals in G25 are these two Yemeni Dhamar and Yemeni Amran individuals. They are only 7% and 6.4% SSA! :crazy: I'm shocked that's really low and would be the amount of Negroid that Saudis get on average in Gedmatch calculators.

From what I remember from older calculators, they score a lot more SSA than now. For example, the Saudis in K8 score around 7.07% while Yemeni Jews are 7.42%: https://docs.google.com/spreadsheets/d/1JVGdg2UsN3jYWgaoxAZu-QsAmuCaq3kT7FvqSXwUsAA/pubhtml

Or in some Gedmatch calculators such as 1) Eurasia K6, Saudis were 6.6% African according to the spreadsheet while in 2) PuntDNAL Global K13, Saudi are 5.5% East African, 1.5% West African and 0.5% South African and Yemeni are 7% East African, 3.5% West African and 0.5% South African according to the spreadsheets there. I want to post the spreadsheets here but I will have to take screenshots.

[Petalpusher]

It's scattered in all 4 components actually to various degrees. The best way to determine real SSA, is to have a West African reference + some ancestral components like in K8. This might create a bit of noise but you ll get some good integer values, if any, for each populations.

Same effect for Oceanian or Papuan/Onge estimate, you can't have some semi ancient components like ANI/ASI or it's gonna capture some. Here "SEA" is probably doing it already.

[Zanzibar]

Arabians clearly descend to a large degree from some very drifted source population and need an additional component to bring their fits to a reasonable level and represent all their ancestral streams better, or else some sub-optimal component like Natufian will eat up all their SSA. G25 is definitely deflating their SSA ancestry to some extent. I can accept that Bedouins might have fairly low to nil SSA and the same may apply to a few Yemeni groups that are located in very remote areas because of their lack of involvement in the cosmopolitan slave trade, but the rest? Hard to believe.

Once we get proper samples, we should be able to get a more precise account of their actual SSA percentage. Although, there’s probably scientific papers out there which have already come to a conclusion on this topic. We’d need to do some looking.

Here is what happened when the Arabians are modelled using the simulated coordinates by Korotyr btw. It seem most of their negroid admix is now ANA followed by minor East African/Dinka-related stuff.

[Borealis]

I just tested out those samples you sent me. I used only moderns as references because ancients is too troublesome for these many samples. I also left out the Levantines because they can't be modeled with the same modern groups that peninsular Arabs and Iraqis can(they need something more ANF). Couple things I've noted:

1. The Iraqis here are just like the Iraqis on the regular spreadsheet.
2. There does seem to be some Arabian individuals with far higher SSA than the samples currently on the sheet.
3. One of the Yemeni samples is over 40% South Asian, clear outlier.
4. EmiratiB is heavily Persian admixed with some South Asian ancestry too. EmiratiA is also admixed with those groups but to a much lesser extent. 2 Saudi samples and some Omani samples also have fairly high Iranian ancestry.
5. The highest SSA is found among an Omani individual(OMAN3).

Answer is simple, those heavy SSA admixed invdividuals were removed from the sheet.

When I tested original datasets some have 20% SSA or more:) But they are not included.

In G25 always some samples are removed from datasets.

In old Gedmatc calcs they use all samples for refs.

In G25 always some samples are removed from datasets.

In old Gedmatc calcs they use all samples for refs.

Why did they remove the individuals with a lot of SSA blood from the samples? They are very dishonest if they do that. Are they afraid of Yemenis being seen as heavily Negroid admixed?

Can you add those heavily negroid admixed Yemenis and other Peninsular Arabs to the G25 spreadsheet?

Few Yemeni did mix with afro Yemeni it could be the reason for having high SSA blood even tho the majority of Arabians they hardly mix its a tribal thing.

Most Arabians even tribal ones still score a lot of ANA/Ancient North African admixture which is a Paleolithic indigenous African ancestry much closer to SSAs than to Eurasians though. Arabians got this ANA blood from their heavy Natufian ancestry. Many Yemenis would receive Dinka/East African blood from Cushitic admixture as a result of close geographical location to Horn of Africa like Somalia.

I just tested out those samples you sent me. I used only moderns as references because ancients is too troublesome for these many samples. I also left out the Levantines because they can't be modeled with the same modern groups that peninsular Arabs and Iraqis can(they need something more ANF). Couple things I've noted:

1. The Iraqis here are just like the Iraqis on the regular spreadsheet.
2. There does seem to be some Arabian individuals with far higher SSA than the samples currently on the sheet.
3. One of the Yemeni samples is over 40% South Asian, clear outlier.
4. EmiratiB is heavily Persian admixed with some South Asian ancestry too. EmiratiA is also admixed with those groups but to a much lesser extent. 2 Saudi samples and some Omani samples also have fairly high Iranian ancestry.
5. The highest SSA is found among an Omani individual(OMAN3).

Thanks for your feedback! BedouinA has around 6-7% SSA though so using them could depress the SSA blood in these new samples quite a bit:

Even BedouinB seems to have minor African which could depress the SSA score a bit:

In my opinion, its better to use Yemenite_Mahra (they have the lowest amount of African) and Samaritans (yes they are Levantines, but a lot of Arabians also seem to have Levantine affinity) to gauge the SSA blood in the new Arabian samples in this case. ETH_4500BP is Mota, an ancient East African closest to modern day Hadza, hunter gatherers from Tanzania.

It seems that the SSA admixture in Arabians overall now increase when using Yemenite Mahra and Samaritans to model them.

I concurred with the rest of your observations made.

Btw another thing that I notice is that for many Yemenis and some Saudis that score a lot of Dinka or ETH_4500BP (Mota), it seems they have a lot of Horner ancestry which gives them high East African/Nilotic-related admixture.

I will post only Arabians with significant Horner admix (>5%). I use KEN_Pastoral_N, a Neolithic Pastoral sample from Kenya who are early Cushites and closest to modern Somalians, to represent this Horn African ancestry.
