The genomic history of the Aegean palatial civilizations

[Token]

Abstract: The Cycladic, the Minoan, and the Helladic (Mycenaean) cultures define the Bronze Age (BA) of Greece. Urbanism, complex social structures, craft and agricultural specialization, and the earliest forms of writing, characterize this iconic period. We sequenced six early to middle BA whole genomes, along with 11 mtDNA genomes, sampled from the three BA cultures of the Aegean Sea. The Early BA (EBA) genomes are homogeneous and derive most of their ancestry from Neolithic Aegeans, contrary to earlier hypotheses that the Neolithic-EBA cultural transition was due to massive population turn-over. EBA Aegeans were shaped by relatively small-scale migration from East of the Aegean, as evidenced by the Caucasus-related ancestry also detected in Anatolians. In contrast, Middle BA (MBA) individuals of northern Greece differ from EBA populations in showing ~50% Pontic-Caspian Steppe-related ancestry, dated at ca. 2,600-2,000 BCE. Such gene flow events during the MBA contributed towards shaping present-day Greek genomes.

Greeks from Steppe_MLBA confirmed

Is it though? I'll read the paper later but would like to know forsure, but at most Greeks from Steppe confirmed.

The quote doesn't specify whether they modelled them with Yamnaya or Steppe_MLBA. Typically MLBA refers to CW, Sintashta, Andronovo, Srubnaya, Fatyanovo, etc, who actually clustered with modern Europeans while Yamnaya were basically just Caucasoid Tatars.

Greek, Albanian and Armenian are pretty different from other IE languages, so it would be interesting to see if they came from the same CW source or Yamnaya. It is a big difference.

Either way, the Greek language, Religion and Y-DNA is from a northern source, but all evidence points to the civilizational process still coming from the east/south with CHG and Levant_N related ancestry(including in Italy), not IE(nor locally born out of EEFs either), before anyone wants to suggest so.

50% Steppe? Awesome. Wonder where they plotted genetically.

So MBA Greeks plot with central Italians? Well, that's not 50% steppe, right? Except other samples are different.

50% Steppe_MLBA/CWC-like.

I remind that many Albanians get central Italian results on both G25 or Gedmatch....

I'm checking other samples too. Soon more.

Wouldn't they plot more north in such case? I'm not sure, just asking. Maybe we should wait for Lucas to run other samples.
