G25 Sardinian DNA with G25 calculator

[nick6899]

I found out on vahaduo the ancient ancestry of the sardinian modern sample has more genetic affinity to the ROMAN/ITALIC mixture than to the EEF one, I wonder why..

Because modern Sardinians, unlike Tur Barcin, have WHG and Yamnaya,

Does that mean romans/italics have affected much the sardinian dna

There wasn't just one influence and these influences being not evenly distributed. Like some interiour Sardinian areas are way less admixed than some specific coastal areas, like around Cagliari.

You see in the YFull tree that the Sardinians from Cagliari in particular have a lot of more recent (since Bronze Age) haplotypes. The exact entry date is unsure, but for example I follow very closely the E-V13 carriers, and they are well-represented in the Cagliari Sardinian sample, and they seem to have entered the island for the most part between the Late Bronze Age and Late Antiquity. Exact dates are up to now unknown.
J-L283 as another rather continental influence being already confirmed by ancient DNA for example.

So there was a constant low level admixture, especially in some coastal areas, coming from various people, mostly via the region of Liguria/Genua. So I'd say whatever dominated North Western Italy left a mark on the island, sometimes more, sometimes less and more so in specific coastal regions like around Cagliari.

The WHG element increased already due to the invasion of Middle-Late Neolithic and Copper Age groups which were richer in WHG and I2 than the original Early farmer population - they expanded there like into other regions of Europe too (like with Globular Amphora culture). Therefore already before the steppe expansion there were invasions and replacement events.

 

[capisan]

Yeah i agree with you i notice many ancient DNA it's close ( not very close ) to samples modern from sardinia

 

[Cato]

According to G25 there is much more "Roman Imperial" than "IA Rome" DNA in Sardinia, although Sardinians are closer to IA Italics or BA/IA Sicilians than Rome Imperials [emoji848]

Medieval colonists may have brought additional Roman/Italic-like DNA (the so called "Northern Mediterranean" ancestry of Marcus et al. 2020)

There are many Pisano/Pisanu (meaning from Pisa), Massa (from Massa, probably they came with William of Massa, judge/king of Cagliari), Cossu (Corsican) in Sardinia.

Also Cadelano, Cadelanu (Catalan)

 

[Ivorix]

wow this is very cool, btw i want to ask why iberiansin g25 have high sardinian? if i get high sardinian in a calculator i should think that is my iberian?

Interesting, I guess the Massa have the best correlation with the E-V13 presence. They are close to the Ligurian/Genuese hotspot of E-V13 and the Cagliari E-V13 samples look like they came from Northern Italy, rather.

[/URL]Would be interesting whether Masse from around Sardinia were tested for the typical E-V13 subclades we got from the Cagliari samples, but I guess other than that sample there is little to work with.

Just a brief comment. My wife is Sardinian, so for some time I've been reading about Sardinian History and genealogy. Regarding some surnames such as Pisano or Pisanu (my mother's in law surname), not all of them came from Pisa, probably many of their ancestors were part of the pisan part of the island on the middle ages, that's why they took that surname. This is proven sometimes genetically, for example there is Gian Tommaso Pisano, born in Sardinia by the end of the XIXth century that belong to the ''tipical'' Sardinian HG I2a1(M26). Unfortunately it's been extremely difficult to convince one of my wife's relative to take a genetic test

Roman Imperial is levantine shifted right?

 

[Riverman]

Roman Imperial is levantine shifted right?

Yes, Anatolian-Levantine shifted.

Thank you for creating a topic and sharing the samples on Europedia!

These are samples I collected via gedmatch and shared on Apricity (FlashBall) and Anthrogenica (Olymp)

Very informative comment Juan. I can confirm what you write, I have seen the results of a Sardinian with surname Pisano/Pisanu and also his Y-DNA is the typical Sardinian I2a1 (M26).

In Italy there are many surnames such as Pisano, Fiorentino, Toscano, Lombardo, Mantovani, Mantovano, Veneziano, Napoletano, Pugliese, Siciliano, Greco, Tedesco, Tedeschi, Francese, Albanese.... and many others of this kind. You are absolutely right that these surnames do not always indicate a true ethnic origin of the progenitor, but they were nicknames also given to local people simply because they had to deal, for work or other reasons, with communities of "Pisani," "Fiorentini," "Lombardi," "Mantovani," and so on. There are other reasons as well, and this type of surname in any case is not always guarantee of an ethnic origin as the surname seems to indicate instead.

True, for instance in the 12th century AD a Sardinian curatore, a sort of tax collector, was called Petru de Serra, a surname associated with the ruling families of the island since the 11th century, but he was also called Petru de Serra "De Ierusale" in some Sardinian documents, because he went on pilgrimage to the Holy Land, but he certainly wasn't born in Jerusalem. Likewise, not all Pisans with the surname "Sardi" or "Sardo" were necessarily descendants of Sardinians, it might've been the case in some instances, for example we know of a Gomita Sardo, son of Guantino, who rented a piece of land near Montieri in a document from 1237, both the name of the son and that the father are very typical of Medieval Sardinia, and not known elsewhere, so he was almost certainly a Sardinian in this case, but in many others instances it could just be a nickname, and a guy could've just been known as "Sardo" because he traded with the island.
A Pisan in 1104 was known as Leo de Babilonia, not because he was from Babylon, which by the way in the Late Middle Ages was used to refer to Egypt and not to Babylon in Iraq, but because he went there, probably on a trade expedition.
