Which Italian regions or provinces have the most Italic ancestry?
Printable View
That Italic average by Brazorf is only 23.8% Yamnaya on the Davidski gold standard calculator. That's pretty low if you ask me. Some modern Southern Europeans would score more. Swarthy Italics :D
Honestly, it's hard to quantify because models are almost always overfitted and do not make sense historically. Of all the Italians, the most akin are those in the north, particularly those with more EEF like the Lombards, although North Italians looks more like the Croatian Iron Age samples since they score a bit more Steppe and CHG/Iran_N than the Italics. The most related are instead the Iberians, although they are not descended from the Italics.

It has high WHG, around duble than modern northern Italians. But lower steppe and modern north Italians have extra "east med". Yamnaya were swarthy pigmented btw.

Italics were more Anatolian farmer (*"proto southern Europeans"), and Anatolian farmers had loads of WHG in them as well. As you can see, Italics lacked Tepecik Ciftlik neolithic like ancestry, which is between anatolian farmers and levantine farmers, brought by imperial Romans from near east/anatolia during imperial times.
Croatian IA Illyrians also totally lacked east med Tepecik Ciftlik like ancestry.

Anatolian Farmers had 0%, the ones with WHG were Pinarbasi_HG (6%) and Boncuklu_N (5%). As a component EEF has little connection to the WHGs.
If I had to guess, I'd say the East Med stuff came in the first two centuries before Christ and not just in the Imperial Age. This period coincides with the highest wrecks in the Mediterranean.Code:Distance to: ITA_Grotta_Continenza_Meso:RMPR15

Also, Tepecik_Ciftlik_N is redundant, since as you also specified it is an almost perfect mix of different components.

Yes, I'm sure. Do you mean deep-ancestry or something like that? Global25 is not the best tool but I get this:

I watched and all points do make sense imo. The somewhat "Balkan" shift of County Glatz is unexpected to me, but it was also already visible in some results.
The fact that all averages do have a meaningful relation to each other on the PCA (showing a bio-geographic cline) confirms that also averages that are based on low sample sizes seem valid, if they are based on deeply rooted samples (like here). Of course nevertheless more samples are much appreciated.
