Genética de españoles e hispanoamericanos

If I am not mistaken I usually get two digits WHG (my family as well). It is being pulled in favor of LBK.

It seems that the more Western Iberian ancestry one has, the more LBK shows.

Also Natufian emerge randomly, at least I have never seen natufian in my parents or in my results.

However, English or Norwegian show quite a high ammount of Iberia_EEF, and I don´t see what is the logic of it.

Iberian EEF has more WHG in it than LBK does, that's why I left the WHG reference there to account for those who need more of it due to high LBK.

Yes you're right, and catalan-speakers should have it as well, with Central and North Spanish strongly preferring the Iberian one. Maybe it's the consequence of a higher rate of non-Iberian European origin, maybe associated with Germanic-like and East Med ancestry? Outside Iberia Iberia_EEF is apparently higher along the Atlantic, odds are these areas retained the highest amount of Western EEF in Europe, which is otherwise dominated by much higher amounts of Eastern EEF.

I wouldn't take this figures at face value, but the trend in different EEF references preference is there. I don't think unscaled coordinates will help, such ancient samples tend to have less reliance on higher dimensions which is what unscaled does by overwhelmingly preferring the first two or three - what's why I usually make these ancient models with scaled data. That said the MAR_EN figures are occasionally silly.


Edit: I just noticed your distances, it's incredible how much better Iberian_EEF are for us

The Iberian EEF must originally be the one that contributed to the current Iberians, LBK sometimes causes weird artifacts in calculators and "replaces" it sometimes, at least that's what I think.

Pre-Roman samples

Spoiler!

Roman and post-Roman samples

Spoiler!

Western EEF dominates in pre-Roman samples, although some individuals also benefit slightly from LBK. The second group is the complete opposite, only a few of them strongly prefer the native EEF references, that includes the Visigothic samples and those with high East Med+North African. Naturally the Reconquista changed the scenario. Since north/central Spanish (Leonese and Castillians) derive more of their ancestry from pre-Roman Iberia, they will prefer Western EEF more strongly than Galician-Portuguese or Catalan speakers do. I think.

This should imply that the Portuguese derive less of their ancestry from indigenous peoples of Iberia (with some exceptions, such as yours truly), not that this is surprising, but there it is.


Edit: Simulated Roman Portuguese samples. I don't trust these coordinates, but for the sake of completeness here they are

Galicia continues to prefer the Iberian Neolithic samples over those of LBK.

What I did notice is that samples strongly influenced by the Mediterranean or Italics tend to prefer LBK over EEF Iberia, the case of the Canary Islands is clear (proportionally to their total European ancestry) and the Balearic Islands (the Baleares, Mallorca and Menorca are among the Iberian regions with higher LBK).

The Catalans are also influenced by this "italic" current, which doesn't surprise me because of their geography.
