My illustrative (North West Somali)

[Garaad Awal]

"These were the Akichu, the largest and the most powerful of this division. A section of the Akichu, that spearheaded the eastern migration eventually reached the sea coast in northern Somalia. ^ Another section of the Akichu migrated to the north through Bawaro, Bat agar and Amhara. Together with the Karrayu, Marawa and Arsi, the Akichu were the scourge of the Christian kingdom as well as the Muslim state of Harar. The second division at Mormor was Ittu, and the third Iiumbana. These three groups migrated to the Charchar-Harar region. "

"Thirdly, from the time of the Birmaje gada (l£78-l£86), a large wave of Oromo migration was directed towards the lowlands inhabited by Somali nomads. This wave became visible during the Mulata gada (l£8 6-139^4) > when large bands of Akichu, Gallan, Warra Daya, Warra Ittu, Jarso, and a number of other groups poured on to the Somali held territory crossing via the valleys of Brer, the river Dakta, and the plains of Babile. The Oromo migrants of the Mulata and Dulo gadas (15>9U~1602), and probably several subsequent ones, carried the raids deeply into Somali territory, sometimes penetrating as far as the sea. Three separate sources claim the arrival of the Oromo on the sea coast, probably by the closing years of the sixteenth century or the beginning of the next. When Antoine d'Abbadie was in Massawa in 181+0, he met an Arabic-speaking Somali merchant from Berbera, who told him that "some centuries earlier the 1 Galla arrived on the coast and destroyed a number of things near Berbera." "


"Secondly, the Afran Qallo (the four sons of Qallo), which was in turn divided into four major clans, namely, Alla (with more than twelve subdivisions), Nole (with six sub-divisions), Jarso-Babile (with ten sub1. I.M. Lewis, "The Galla in Northern Somaliland'1, RSE, pp. 21^-2$. 218 divisions) and Oborra (with four sub-divisions). These four major clans spread over the central highlands of Harar, which include the present awrajas (sub-provinces) of Harar, Gursum, Dire Dawa, Oborra and parts of Gara Multa."


Oromos never claim the Gurgure or the Garre in their clan geneologies. It is clear both these groups are non-Oromos. One being Af-Maxaa Somali Dir and the other being Somaloid Af-Garre speakers

Your fit is terrible for some reason.

Target: Fez Distance: 3.0610% / 0.03061047
93.4	Cushitic
6.6	Syria_TellQarassa_Umayyad

My fit in comparison:

Target: Garaad Distance: 1.9594% / 0.01959432
92.6	Cushitic
7.4	Syria_TellQarassa_Umayyad

It’s either caused by an overcompensation of something or something is just missing. Nonetheless bad fits are a common theme for me as @Rayaale runs have shown.

To be honest, I think people are wasting their time trying to use G25 for modeling individuals. The PCA gets exceedingly wonky for many samples in this setting probably because its dimensions are now too affected by the sheer number of samples affecting the formation of the principal components.

Hence why you'll get nonsensical stuff like Somali samples whose overall MENA ancestry is negligible in range across the ethnic group (2%) then nonsensical results like one sample magically being 10% Arabian and the other 15%. It makes no sense until you understand how PCAs can work and what can affect their output; namely the number of PCs you limit the output to, the SNP count of the samples, and of course the samples used themselves. Not to mention how easy it is, like with ADMIX for things to be skewed by drift even within individuals samples.

When you consider those points it starts to make sense how an ethnic group that clusters so tightly, forms its own ADMIX component, has the same mtDNA lineages across a wide area and is dominated by mainly two greater Y-HGs is showing variation in G25 that makes zero sense. If we seriously had diverse Mota and Arabian scores we should cluster as heterogeneously as Oromos but we don't so it's clearly the methodology that's shooting out incorrect results. Not to mention that you can actually make almost any of these Somali samples show these ancestries they're supposedly missing if you just structure modeling a certain way. Folks need to exercise some critical thinking...

I really would advise people to just stick to the averages when studying ethnic groups via G25 and hope someone creates something like a really fine-scale ADMIX run or something similar for modeling individuals. This guy probably doesn't have any really different amounts of Mota or Arabian than anyone else given his typical overall admixture levels...
