Starting in the 8th century BCE, coastal Campania in Southern Italy became a melting pot of various cultures and peoples when Etruscan and Greek colonizers joined local Italic tribes. By establishing cities and trade posts, the contact networks of Campania were further expanded across the Mediterranean and inland.We generated ancient genomes from Campania, spanning the 8th to 3rd century BCE,i.e. the Orientalizing, Archaic and Hellenistic-Roman period in this region. While most individuals can be attributed to a genetic ancestry that arose on the Italian mainland, we also discover descendants of migrants from the Aegean and Eastern Mediterranean.Most notably, an individual dated to the 8th century at the first Greek settlement,Pithekoussai, a site that also yielded the earliest example of writing in the Euboean alphabet, was genetically of Aegean origin, and we find that this type of ancestry persisted at the site for several centuries. We compare the genetic composition of these descendants of Greek settlers to the local Campanians represented by individuals fromthe site San Marzano and Etruscan immigrants from Pontecagnano.We integrate a thorough analysis of the associated material culture and, where available,strontium isotopes to establish temporal and cultural patterns of mobility, ancestry andadmixture that shaped the genetic landscape of Campanian Magna Graecia.
Keywordsmobility, Magna Graecia, ancient DNA, migration, bioarchaeology

i understand from anthrogenica that this study was presented today by alissa mitnik
maybe we would have some leak ....:)


p.s
if e-v13 would be found among those with greek autosomal profile that would be great

Thanks, I'm sure it would be useful for J2 L70's as well!!

i am sure j2 generally speaking would show up i would be in shock if not:unsure:
about j-L70 i hope for you :wink:

Many Thanks. I'm quite sure J2 L70 is part of the greek signature in Magna Graecia, as it is on central-southern Italy today.
 
No matter how you look at it... the Danubian lime paper methodology is trash, what I said by taking one look at it. And I believe Pax also had some similar feelings without further specifying what at the time.

The distances in the Italian model you posted are bad. And that's on g25 which isn't a formal tool, so obviously this model would fail with qpAdm. I can't post links at the moment in this forum, but if you try modelling South Balkanites with BGR_IA + Slav on g25 you will see that the distances are much better compared to the Italians you posted. Obviously, this isn't a hyper-accurate historical model either but it's undeniable that South Balkanites need a southern source to model them accurately, in addition to early Iron Age Balkan and Slavic. Models using only HRV_IA + Slavic fail miserably for Bulgarians, Greeks, Macedonians, Albanians and aren't great even for Serbs. Adding Rome_Imperial gives much better distances which should give you a hint about happened in the Hellenistic and Roman periods.
 
Perhaps there is a way to explain the results supposedly showing "Slavic" in Italy (35% in Bergamo) so that everyone understands.

The people in Europe with the highest "steppe" percentage (which is not Yamnaya, btw, but includes a lot of additional EHG) are the people in the Baltics (according to Eurogenes, anyway, which is what his calculator, unsurprisingly, shows, while most people say the Scandinavians).

So, a "Baltic" percentage can stand in for steppe in general, Germanic, and, indeed, Baltic, which is why Eurogenes designed it that way: Poles wind up being very "steppe" and "Baltic" like.

It's completely imprecise and unscientific because it's based on modern populations, and not the dna of the actual invading or "migrating" peoples, if you prefer.

So, for people in the more northern areas of the Balkans, it MIGHT include some proportion of Celtic and Germanic, although given the history and archaeology and the yDna, in the Balkans they would be minor components.

In Italy, given the history and archaeology and yDna, it is original steppe invasion, plus Celtic, plus a bit of Germanic, and it's on a cline from north to south, with the north having more of it.

For the record, as I indicated above, that "Baltic" component in Eurogenes is inflated for everyone, because he made it to show inflated percentages in people like Poles.

It's a bit offtopic but, it seems that the rumor on AG about the Egyptians from Old, Middle and New Kingdom being less SSA admixed than modern ones, could be true. I got this from ES forum where a user quoted another one saying this:
I am in contact with an academic in the know regarding some new aDNA papers on the way and I'm sorry to inform some of you that we have Old, Middle and New Kingdom samples on the way and, so far, they mostly don't look anymore proto-Nilotic than Copts, some even less so:

There is some upcoming data from Old and Middle Kingdom Egypt that I've seen, some of it has been discussed already on the forum. Basically the Old Kingdom samples look North African with a small amount of Seh_Gabi_C-type ancestry, and very little SSA, then during the Middle Kingdom there's a shift towards a SW Asian/Near Eastern profile which resembles that of the few ancient Egyptians we have and present-day Copts, this corresponds with the large influx of "Asiatics" starting from the 1st intermediate period. SSA ancestry also increases in time. Haplogroups so far are E-M35 and J1-P58 (wish there were more resolution, looks like we'll have to sift through the BAM files again).

The old kingdom people are probably the so far closest we're gonna get to Horners' non-Yemeni MENA ancestors. Some sort of intermediate in Egypt between Iberomaurusians and Natufians with a little bit of proto-Nilotic. Though I wager our ancestors lacked that Iran-Chalcolithic (Seh_Gabi) stuff. Now, I would never rule out that some ancient Masris on the border with Nubia like in Luxor were more proto-Nilotic for sure but the majority probably were mostly MENA with the only really significant "SSA" in them being "Ancestral North-African" that has mostly survived haplogroup wise in the form of their dominant Y-DNA E-M35.

Maybe the higher than usual y T percentages in Stilfs (S. Tyrol) is due to genetics ,
… surely they cope well against Acute Mountain Sickness.
… I would probably thrive there too :)

We agree. (y)

Couple of future papers should give us better source populations.
 
I am not even sure there is any slavic in this paper either

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3658181/


Genetic characterization of northeastern Italian population isolates in the context of broader European genetic diversity



Maybe the original people became slav due to learning slav linguistically..........

My wife line come from Motta di Livenza ( Treviso province ) , San Stino di Livenza ( Venice province ) and Gaiarine ( Treviso province )...............the Livenza river separates Veneto and Friuli

Her family line ( paternal ) circa 1700 came via the Carnian Alps , which is north-west Fruili , same area roughly as the paper above...............but she has no slavic admixture

Angela: I think this is the final published version of the abstract version of the paper that Kingjohn linked in the OP. Perhaps this paper now should have a new Thread since it has been through editorial and peer review process and is now published. The Y and mtdna Haplogroups are in Supplement 2 for those interested.
