Near complete lack of Steppe input in some South Italians?

[Sikeliot]

This is a chart from Sarno et al 2017

They measured four components in the population as I have explained on the forum many times:

Yellow = Caucasus/CHG (peaks in Georgia)
Green = EEF/Sardinian (peaks in Sardinia)
Red = Near Eastern (peaks in Palestine and Arabian Peninsula)
Blue = Steppe/European-like (peaks in North and East Europe)


If you look, there are some individuals on here for whom the red bar goes all the way to the x-axis, which means there are a few Sicilians in the Catania, Ragusa, and Palermo clusters who appear not to have any of the blue Steppe component.

For this to be the case it would have to imply very limited input from Normans, Lombards, or mainland Greeks (post-Slavic migration) and near isolation for the last 2000 years.

The average Steppe for Sicily as a whole is around 20% and the fact that you believe there are native individuals in modern day Southern Italy that have no steppe input all when this admix was introduced to the area over 3000 years ago is kinda mindblowing.
And these components, did she base them on modern people or are they actually ancient components?

Every European group has steppe input, it's practically impossible for a certain group such as Sicilians to not have any.

The blue component there, as you can see, is lacking in some of the individuals. So you could argue there is hidden Steppe elements in the Sardinian component, but the blue component which is lacking in some southern Italians altogether, seems to be based on modern NE Europeans.

Sardinians do not actually but they may be the only ones as a collective.

I'm pretty sure that genetics have shown that they have Steppe input just at very minimal levels. Sardinia also has some R1b which is U152 though I2a1a-M26 does dominate.

So it's not Steppe at all then. It's just a random ADMIXTURE run with modern components. Nothing new.

This chart is bad too, Southern French more steppe than Croatian and French? Tuscans with more steppe than Bergamo? Btw, Haak 2015 is one of the first studies on the subject.

Yh it isn't the best either, I mean Spanish on here have no WHG lol. I posted it just to show that Steppe input is present in Sardinians

It appears to me, to be modeling South Italians as a mixture of Sardinian, Caucasian, south Levantine, and North European. So what I should have said is some of them show no North European.

Sardinians have some level of steppe ancestry, except for Gairo.

No, Sicilians have around 20% steppe admixture.

Then Steppe cannot be NE European, because some of them have almost none.
