New African Admixture in Iberia

[Damião de Góis]

I never said you had 15%, I said portuguese in average have around 10-15% NA ancestry which is confirmed by the studies about your people that you don't read. I run your coordinates and compared to the average portuguese you have less NA admixture (around 8%) but unlike the average portuguese you do have ssa ancestry (2%) and it doesn't seem to be related to NAs nor is it "noise" (this same ssa admixture among portuguese is also confirmed by the study mopi posted I invite you to read it)

So we're back where we started?



All this spectacle and doubting my results for nothing?

what you posted just confirmed what I said...

So explain your math at least. Given the run and table i posted where are you getting the remaining percentages to get from 5% to 10-15%?

simple look at my results :

Target: Hamilcar_scaled
Distance: 2.9501% / 0.02950090
46.0 Anatolia_Barcin_N
27.4 MAR_Iberomaurusian
12.0 Yamnaya_RUS_Samara
6.6 Yoruba
5.0 Levant_Natufian
1.6 IRN_Ganj_Dareh_N
1.4 WHG


I'm only 27.4% IBM and portuguese have in average 5%....I let you do the math.

don't these results just prove that North African's component is not as dependent on iberomaursians as thought? So why is it so significant, if you as a native NA, barely get any of it yourself? It's interesting to me... saying that this component is what largely overlaps in ancient sources with Iberia already with inevitable portions. So in reality you gotta include the Levant, samara, Yoruba, IRN components into the iberomaurasian to make it a true NA percentage. It is more complex than it seems people think, and we obviously do not have enough research to conclude the correct % to the decimal.

Fully 100% North Africans (Morocco, Algeria) get consistently between 30 to 40% IBM (depending on the region), so what Hamilar is trying to say is the following:



Though I'm not sure if its oke to make this calculation as there may be some other factors coming into the play when it comes to the spread of autosomalic DNA.

Oh I see. Yeah I get what you’re saying.

well you can question this calculation but I don't think it's a coincidence if the studies show similar results. Here an example :

Within the Iberian Peninsula, the admixture proportion of North African ancestry in southern Portugal samples was 11.17 ± 1.87%, similar to the values observed in Galicia (10.30 ± 1.64%) and western Andalusia (present study, 9.28 ± 1.79%). The Canary Islands (not selected here) exhibit extreme values of the inferred Maghrebi cluster (26%) (Guillen-Guio et al. 2018). Asni Berbers carry the highest proportion of the native Maghrebi ancestral cluster (82.74 ± 8.36%) with respect to the other Moroccan samples.

The problem that I see is that 25% is a completely Algerian or Moroccan grandfather, that is to say that a person with 8.75% IBM necessarily has a direct grandfather native to North Africa, and there are Iberian people exceeding 7% IBM according to some models with what is 20% NA, this is much more than a great-grandfather.

I would get 18.8% (along with the SSA).

no it doesn't necessarily means you have a north african grandfather lol Are you going to say ethiopians have a yemenite parent because of them being around half natufian ?
