How much steppe admixture is there in Corsica/Sardinia/Malta/Ibiza?

[Voskos]

If any.

If any.Malta it's around 20%

Sardinia 0 surely. They have a good amount of WHG however.

Still around 5-7% imo.

Do we have sample from barbagia and ogliastra?

No idea from which region the samples are from, they're all the Sardinian samples in the G25 database. I think there are more but not added to Davidski's G25.

It's funny how I've looked to see from which region within a small island some samples are but there are barely any Romanian samples. Life is tough

Sad. Big hug.

@weirdlookimgfellow,

Thanks for posting runs. 30% for corsica seems too high imo, this tool is not always that accurate.

It might be stealing some WHG admix if we consider the lack of WHG in Maltese.

@Weordlookingfellow,

Could you try this model:

Iran Neo
Anatolia Neo
Natufian
WHG
MA1

[Samnium]

Still around 5-7% imo.

Malta hasn't 30%/35 Steppe, these numbers are for Spaniards/Portuguese/N.Italians.

They are around 20%

@Weordlookingfellow,

Iran Neo
Anatolia Neo
Natufian
WHG
MA1

Which Iran N, Tepe_Abdul_Husein or Ganj_Dareh? Also which MA1?

[Voskos]

Ganj dareh would do. As for ma1 , any option would be ok as long as it's the MA1 ANE genome.

Haak et al. (2015) conducted a genome wide study of 94 ancient skeletons from Europe and Russia. The study argues that Bronze Age steppe pastoralists from the Yamna culture spread Indo-European languages in Europe. Autosomic tests indicate that the Yamnaya-people were the result of admixture between two different hunter-gatherer populations: Eastern Hunter-Gatherers from the Russian Steppe and either Caucasus Hunter-Gatherers or Chalcolithic Iranians (who are very similar). Wolfgang Haak estimated a 27% ancestral contribution of the Yamnaya in the DNA of modern Tuscans, a 25% ancestral contribution of the Yamnaya in the DNA of modern Northern Italians from Bergamo, excluding Sardinians (7%), and to a lesser extent Sicilians (12%).

Leto, you got any corsican gedmatches?

[Leto]

Leto, you got any corsican gedmatches?
No, none. I don't really look for Italian or Southern Euro numbers, my main focus is Eastern Europe and ancient Aryan ancestry. Sorry.

When modelling east med like populations it's better to include the usual 3 ancient near east references, CHG, Iran_N and Natufian. Needless to say Malta in particular also needs something north African-like.

Sardinian;HGDP1078 should be from Barbagia, the most isolated region of Sardinia. Do we have his gedmatch kit?

Thanks my dude, mon poto.

[SharpFork]

Why do Maltese samples appear to have this much Yamnaya? It seems weirdly more than Sicily.
