myHeritage is very bad, don't take it too seriously.

[Brás Garcia de Mascarenhas]

He mentioned in the comments section that he has a Polish grandparent. He is half-Angolan\half-Congolese, his European ancestry is likely from his Angolan side of family. Angola became independent during the Cold War and was aligned with the Soviet Union as a self-proclaimed Socialist Republic. For that reason a few prominent Angolan figures that fought along the Communist guerrilla rebels against the Portuguese state would study in former Soviet Republics or other Communist states and sometimes relationships were born through that exchange. The former president of Angola, José Eduardo dos Santos, was married to a Russian female as an example. I am extrapolating a theory but it seems plausible and could explain why it gave him some Baltic and Scandinavian.

Ancestry x MyHeritage
Is MYHeritage a garbage test ?

It's widely accepted All Africans have some ancient Eurasian, at least 2-3%, maybe a few isolated groups dont, it's up to 40-50% in Horners mostly from a migration of basal Eurasian groups. It also explains some of the frequency of R1 found in Africa.

Ancient Admixture into Africa from the ancestors of non-Africans

We find evidence for substantial migration from the ancestors of present-day Eurasians into African groups between 40 and 70 thousand years ago, predating
the divergence of Eastern and Western Eurasian lineages.

However commercial tests can only give them some modern groups and can't quite figure what kind of Eurasian it might be. Those commercial models are not much more than a vahaduo mix mode, which is not quite the same material in terms of admixture informations, it's the processed good already trying to figure out a fit. The value is in the raw dna sequencing.

But is that actual Caucasoid admixture? I think in Ethiopia the Eurasian ancestry is from some Arab-like groups. Ethio-Semitics.

Several backflow events, for Horners specifically, some of it is recent, some of it is ENA or Paleo. Difficult to give it a modern similarity within all that, but there s been several backflows at different times for sure in east Africa as entry point. Even North African's 70 to 90% Eurasian didn't fall off the sky either.

San cold adapted phenotype and pseudo Mongoloid always bugged me, that could be explained with some ENA and be from a more east eurasian related source within the Eurasian groups of the time (around 50Ky).
Now despite all that, they are still incredibly far from Eurasians, and we still have yet to find some ghost population that will eventually be found but already predicted.

Now these particular subjects are treading on thin ice, as far as OoA and multi regionalism are concerned, because it increasingly looks like a lot of things went into Africa, and not much went out of it other than putative stuff we don't have the beginning of a bone. Even in this study they don't find bidirectionnal flow, which is still weird.
