So they aren’t that ancient admixture
What do you mean?
Somalis intermarry a lot so it is unlikely that some would not have that admixture
Idk, maybe Northern Somalis have more of the Arabian?
Some Somalis lack it while other can reach high double digit Arabian ancestry.Some Somalis also have Mota ancestry from the Ethiopian Highlands while others don't

Is that Cushitic mean horn African nilotes and Cushitic mix?
Cushitic represents the ancestry that we derive from our proto-cushitic ancestors which is the vast majority of our ancestry
And in my case, all of my ancestry apparently
But it sees that 100% Cushitic
Yes because he is 100% Cushitic, are you good my guy?
Can be that way with some people outside the main dataset, in my experience. It will be overfitting but you can likely make it appear in you with the following run models:
- Go to the individual Somali samples and take "Somali15". Use this sample in the source page and list it as "Somali". Then throw in Jawf-Yemeni or Yemenis in general as well as Mota and Dinka. It will probably pop-up then.
- Or use the average for the Kenya Pastoral Neolithic samples as a base in source then throw in Mota, Dinka and Jawf-Yemeni alongside it.
Should appear at least 5-10% like the Somali average.
Just a region of Yemen Horners seem to have a particular affinity for. They do, if I recall, have some possible minor Horner admixture like most Yemenis. So that's worth keeping in mind. To be honest, I'm starting to think this admixture is not real in Somalis and what Somalis actually have is Bronze-Age Egyptian ancestry through a secondary expansion out of Sudan between 3000 BCE and 1500 BCE that would have brought things like farming and tools like the plow:
Your father's numbers would likely shoot up with the sorts of models I mentioned above. I'd hold off on being sure that there really is much variation among Somalis for this ancestry. It doesn't add up with how homogeneous Somalis are in terms of basal MENA ancestry:
Seriously, unless someone has recent foreign ancestry like some of those Kenyans, the range is like 2%. We form a very tight cluster. That should be impossible if we have widely varying levels of Mota and Iron-Age Yemeni or Bronze-Age Egyptian ancestry.

That dna probably belongs to a dead person 3000 years ago. There is no pure 100% Cushitic
I think its strange how when I use Yemen on G25 Horners score no Levantine at all (PPNB, Chalcolithic Israel), we just score Natufian + Taforalt + SSA. Taken literally, this would mean North Sudan in the Bronze age had no Levantine ancestry which is practically impossible, I think the Yemen is absorbing some of the Levantine ancestry that would have come via Egypt, it would explain why even some Pastoral Neolithic genomes prefer Yemeni over direct Levantine sources on G25(even the 4000 year old ones) and wont score much if any Levantine if a Yemeni source is included, when they definitely have no Yemeni ancestry, this phenomenon would apply to all Horners doe, not just Somalis, as it depletes the Levantine in pretty much all of us
And that makes that person indigenous for the last 3000 years without any recent Arabian,Bantu or Egyptian input.What's your point?
@Shimbiris I would agree with your hypothesis about Egyptian-like ancestry in Somalis but Egyptians are a Anatolian_Barcin heavy population and even basal runs you can find such ancestry in Nubians/Beja but not in Somalis or Horners.We clearly have ancestry from a population with low Barcin and high Neolithic Iranian ancestry which only fits the Arabians.
The Egyptians though share significant ancestry from our common Natufian-like ancestry which is specific to NE Africa with excess IBM plus their minor AEA ancestry so that might make G25 have difficulty choosing between the Yemenis and Egyptians

I think this is an issue particular to G25
Among modern populations, Sardinians showed the highest genetic affinity to both the
Toubou and Amhara.
(B) Ancient Eurasians also showed correlated affinity to both the Toubou and Amhara; the early Neolithic LBK (Linearbandkeramik, or Linear Pottery) population (~5,000 BCE) had the highest affinity.
We then looked at the correlation of the f3 statistic values between the two tests (Figure 4A). We found that the Eurasian source populations for the Amhara and Toubou were highly correlated (r ¼ 0.98; 95% CI ¼ 0.98–0.99; p value < 2.2 3 1016) and that the most significant result was for present-day Sardinian
We repeated the tests by using published ancient genomes (Table S6) and also found a high correlation of the Eurasian sources for the Amhara and Toubou (r = 0.98; 95% CI = 0.97–0.99; p value < 2.2 × 10−16); early Neolithic farmers were the most significant contributors, as reported previously5 (Figure 4B). When we substituted the Amhara with other Ethiopians (Wolayta and Oromo), we found similar results (data not shown).
Chad Genetic Diversity Reveals an African History Marked by Multiple Holocene Eurasian Migrations
Understanding human genetic diversity in Africa is important for interpreting the evolution of all humans, yet vast regions in Africa, such as Chad, r…
The NAF component alone, on the other hand, can be described as a mixture of Anatolia_N and CHG. Particularly, Amhara, Oromo and Wolayta NAF components can be modelled as ~85% Anatolian_N and ~15% CHG, while Ethiopian Somali NAF is better characterized as 92% of Anatolia_N and 8% of CHG. In sum, similarly to Minoan and Tunisian Jewish populations, the non African component of Ethiopians can be best modelled as a mixture of ~85% Anatolian_N and ~15% CHG composition of ancestries
I'm aware of the fact that masking African ancestry as was done in the 2nd paper would have also removed the African ancestry that would have come via our Eurasian sources, but either way we can be modelled well using EEF rich groups, taking G25 models literally would mean Bronze Age North Sudan and to a lesser extent Upper Egypt would have been nearly devoid of Anatolian ancestry.
I disagree completely the amount of Barcin ancestry necessary for us to be partly Egyptian-like is a lot.Horners West Eurasian side seems to basically be Natufian-like + IBM + minor Iran_N + very minor Barcin ancestry.
G25 works perfectly showing the Barcin ancestry in Tobu,Nubians and Sudanese Arabs.I am not saying we don't have Barcin ancestry, it is just too low for G25 to pick it up and the only reason it is low is because of our Cushitic + Arabian ancestry.
