Yes, your quote Is essentialy correct. I'm investigating this "Subsequent immigrations of other Mediterranean peoples have affected the racial composition of these islands but little."Originally Posted by Piquerobi
As i wrote in another thread Marcus, Fernandes and Moots believe that there was 100% continuity in Sardinia between the Neolithic and the Bronze Age while according to Villalba Mouco:
"However, applying the same qpAdm model (text S7, fig. S3, and table S2.5), we detect a previously unreported amount of Iran_N-like ancestry in central Mediterranean groups from Sardinia, ranging from 2.8 ± 1.2% in Sardinia_Chalcolithic to 5.8 ± 1% in Sardinia_Nuragic_BA. Adding Iran_N as a source to model Sicily_EBA improves the model fit but without reaching P values ≥0.05, making gene flow from the Italian Peninsula to Sardinia more likely (Italy_CA also shows Iran_N-like ancestry) than from Sicily (Sicily_EBA)"
And Patterson:
"In Sardinia, a majority of the BA samples
474 do not have Steppe pastoralist-related ancestry. In a few individuals, we found evidence for steppe
475 ancestry, though in most cases, the Steppe pastoralist-related ancestry proportion overlapped 0,
476 and the dates were very noisy (Table SH). Using Iron Age samples from Sardinia, we inferred the
477 gene flow occurred ~2,600 BCE, though there is large uncertainty associated with this estimate
478 (2,614 +/- 560 BCE). "
