View Full Version : Some Sicilians and Calabrese have almost 0% Steppe/NE European

Blue bars are the "European-like" Steppe element from Sarno et al.

If you look closely you can see for "SSI_SIC_PA" (Palermo), "SSI_SIC_RG" (Ragusa), "SSI_SIC_CT" (Catania) and "SSI_CAL_RC" (Reggio Calabria) the red bar for Near Eastern drops all the way to the bottom, meaning that there is no blue Steppe component.

They can therefore be modeled simply as CHG (yellow) + EEF/Sardinian-like (green) + red (Levant/Arabian).

That is taken off of a Structure chart. Structure shows different results for different numbers of "K" (K, corresponding to the number of clusters specified). At a higher level of K, some Steppe admixture might show in them.

It's just really interesting because it implies that they have been exempt from Norman ancestry, anything recently Greek, and probably even much of the Italic admixture, but they are not as far back in time as Sardinians as far as isolation.

It doesn't imply anything without context at hand, really. You have to truly understand how Structure actually works before making claims like that, as they might be far fetched. For example, I can show you a structure analysis that portrays the French as very East Asian like until K= 10

the levels of admixture someone gets in structure all depends on the number and types of populations involved in the analysis, as well as the number of clusters (K = #) specified. More context is needed to asses whether you claim is the case.

Here is the study: https://www.nature.com/articles/s41598-017-01802-4

It looks like, of course, it is not on a population level I am seeing a lack of Steppe but there are select individuals who are not getting any.

Steppe is Rethelite monkey blood anyway. Who wants it? I probably have less than 5% of Steppe blood in my veins.

I have a lot of steppe in me :((((((

Why, though? You're AfG2han, not R1ethelite.

It is interesting to me there are still people in far southern Italy who don't seem to have absorbed any Steppe admixture.

They are the ultimate Neolithic wogs.
