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.

Yana is the oldest ANE lineage we have, but the ANE ancestry seen in Amerinds and Siberians is apparently more closely related to Malta and Afontova Gora. Yana doesn't seem to have left much in the way of descendants. In other words, the Proto-Americans didn't mix with early Yana-like ANE but with later ANE from the west. The only reason I brought it up at all is because Eastern Siberia was taken over by Proto-American East Asians moving in from the south at some point after Yana lived, so it's not surprising to see a lot of Proto-American ancestry on the Lena near Lake Baikal 17,000 years ago. That's exactly when I'd expect it to be there. And Khaiyrgas has more ANE ancestry than its relatives to the east, in line with geography and its proximity to AG3.

Yes but if Khaiyrgas-1 is contemporary with AfontovaGora3, it mades much more sense that it's more closely related to malta and afontova gora than yana. let just say That Yana was a close cousin of the population leading to Malta and AG3.

Can anyone find any more information on this paper? Even a supp file?

Not sure if those MBA samples are from Greek contexts, but if they are, it's not surprising. Northern Greece would not have been part of the Aegean palatial civilizations of the Minoans and Mycenaeans anyway.

The only thing I managed to find was the same submitted data, only on the ENA.

There isn't a Center Name in the project description, so no idea who even published this study...

It is also interesting to note that the same Siberian population that gave rise to modern Siberians, Native Americans and mainstream East Asians carried mtDNA haplogroups A, B, C'Z and D and developed EDAR, probably in order to adapt to the environment.

Three UP mtDNA haplotypes that have been detected came extinct in Siberia, i.e. Salkhit N*, Yana U2’3’4’7’8 and Malta1 U*. Tianyuan B* seems to have been more successful even if this exact haplotype is not exactly ancestral to modern B.

Moreover, I would like to mention that those mainstream East Asian haplogroups that are not shared with Native Americans seem to have a connection either with Jomon or Tibetans or Onge-related paleo populations of the south:
N9a -> N9b has been detected in Hokkaido, Tohoku and Kanto Jomon, N9a6 in modern Orang Asli of Malesia
M12’G -> G1b has been detected in Hokkaido Jomon and M12 is currently found in Australia and Sri Lanka
M7 -> M7a has been detected in Hokkaido Jomon, M7b'c in Kanto Jomon
M10 -> M10 has been detected in Kanto Jomon
M9’E --> M9 is one of the oldest haplogroups in Tibetan highlanders
Moreover, 19 kya old Minagotawa man from Japan is also mtDNA M.

R9’F is not present in Native Americans, but it is present in modern and ancient Siberians, e.g. in Ust'-Belaya II Angara river I7759 Mos82 7160-6910 calBP F1d and Early Neolithic SW Yakutia Matta-1 N2a 4895-4725 calBCE F1d.

I wonder if Logkas is from Corfu.

This is an extremely interesting find, I was not expecting J-Z36834 to be one of the markers of the Cycladic Culture, but it is not a complete and total surprise either since the Mycenaean we have is under J-Z6057 and likely the same branch (quality of the Mycenaean sample was not great), so here begs the question, since J-Y13128 its father branch has already been found in Neolithic Croatia and Hungary, was this sample a local Neolithic survival branch or did some of J-Y13128 stay in Anatolia and moved into Greece via Cycladic Culture, also at least it seems the Mycenaean J-Z6057's origin is solved, he was the descendant of the local Cycladic Culture.

Really exciting to see Ancient Greece be represented more

Hopefully we get more very soon.
