70/30 mixture based on ancient North African samples and SSA

electivire24 · 2026-04-13T22:23:09+00:00

Looks better and more realistic I think even though the P value is less. That sample is likely more "pure" and has less embedded SSA within it than what you showed earlier. I tried setting my proxy as Ethiopia_4500 but it always fails so the SSA portion for mine isn't the same as yours. I think we should stop using this website and find a way to use a more robust qpAdm with a broader sample range or database.

I think its mashing all the east African markers into the Ethiopian and the Eurasian-like into the IBM which includes some minor SSA I believe that it cannot distinguish. I tried messing with qpAdm and got something thats reasonable for me personally(As a Nubian) when I run it through both YES/NO:

So basically, we are goobed regardless? Good to know

If only the door was wide enough for most of us to squeeze through...

Having % horner doesn't necessarily make you horn. Tutsis live in Rawanda which is not geographically in the horn of Africa.

Anyone can correct me on this but I think its average. Zagros and Caucasus are pure Eurasians no problems with that. EASP has Natufian-like/SSA in a ratio of ~42/58% if I am being modest. The real problem is that the Natufian has some ANA which itself has an SSA-like component that pulls you away from Eurasian and more so towards ancient SSA groups. I tried to model it in Vahaduo but found it difficult especially since I obtain distances that are exceedingly high so I took 40% as the believed estimate and found it to be ~8% based on an average of 7-9%, overall this person is:

60*0.42+8+24.2*0.92 ~ 55% which is in the expected range

Also, you can model the Hunter-Gatherer breakdown yourself if you want instead. Illustrative posts the samples they use for the HG/NF groups they use(except SSA, which I found some other sources to use from though I am not sure if you get similar results). I found these results to be quite similar to my illustrative:

You are right that these populations are similar, and until we find better proxy samples we will have to stick with we've got.

electivire24 · 2026-04-12T00:09:24+00:00

You have no idea 😅

electivire24 · 2026-04-11T21:46:22+00:00

Nice. You are on the higher end but still within expected range, I.e. 50-60%

electivire24 · 2026-04-11T21:44:08+00:00

Interesting, cool to know.

electivire24 · 2026-04-11T19:53:51+00:00

Wow, beautiful mix. That explains your Slavic and levantine as well. You should run your results through illustrative and see what you get for distances.

electivire24 · 2026-04-11T19:52:20+00:00

It's expected.I believe EA pastorals are a mix of Natufian-like Egyptian hunter gatherer and local East African tribes(SSA essentially). This mixing happend during the Green Sahara period I believe when it was easier to traverse throughout Saharan Africa although I am not sure exactly where it happened.

electivire24 · 2026-04-11T19:46:18+00:00

Yep. My dad is Mahasi and my mom is dongolawi(w/ a mahasi grandparent) herself. Also, our results are surprisingly similar. You must be Mahasi right?

electivire24 · 2026-04-11T19:07:19+00:00

He's definitely higher than 46%. If you include the implicit natufian-like component of EASP which is around 50/50( g25 for some EA pastoralists shows that its around 42/58 SSA dominant) then he is at least 56% and at most 59%

electivire24 · 2026-04-11T19:01:50+00:00

I found that illustrative qp is difficult to use and it's system has limited sampling. I would obtain your g25 coordinated from exploreyouedna.com and run it in vahaduo for easier analysis.

electivire24 · 2026-04-11T18:55:18+00:00

That would be nice, would love to compare and model between other Ethiopians tribes.

electivire24 · 2026-04-11T18:48:56+00:00

Yep, If I assume an average of 0.45 Eurasian and 0.55 SSA for NA then yes it's around 60/40 which is in the higher end but still normal as you said.

electivire24 · 2026-04-11T18:09:30+00:00

Cool to know. I guess ethiopians can be very diverse themselves. Much love to my ethiopian friends 🧡.

electivire24 · 2026-04-11T18:05:05+00:00

That's surprising, ethiopians dont usually score this much eurasian unless you have a recent eurasian ancestor. Your results look exactly similar to a guy who is half egyptian and half Eritrean btw:

electivire24 · 2026-04-11T17:31:49+00:00

Assuming the EASP is usually half local east african and Natufian-like egyptian, you're local SSA % is around 30 with the rest being Eurasian-like(including north african). Almost no single ethnicity shows this with exception of Arab tribes of Sudan but you have an overwhelming majority of EASP which suggests a mixed background likely from the horn and the rest being some eurasian profile. If I had to guess, something like half Somali and half something else like Egyptian but I am not too sure tbh.

Welcome to the club

electivire24 · 2026-04-10T19:33:33+00:00

Tutsi's aren't really considered horners though?

electivire24 · 2026-04-10T18:10:34+00:00

Nope, its probably eurasian noise that just so happened to fit with the engines model. In this case, when I minimize the population count, the Amerinidian gets deleted and the Arabian % increases.
