We also reconstituted the excavation of a burial from the Aisne valley. 8/10

In the exhibition, we present didactic material, facsimile reproductions of material from Çatal Höyük, printed and painted by the talented Laurent Aubry from Trajectoires 5/10

The Agripop exhibition deals with the beginning of the spread of farming into Europe as seen with paelogenomics. This exhibition project evolved from the Neomatrix research network @neomatrix.bsky.social 2/10

Finally, the Buran Kaya III individuals are more closely related to present-day individuals from Europe. 12/14

The Gravettian culture has produced stunning female sculptures like the various Venuses of Vestonice and Willendorf and the head of the Dame de Brassempouy. The genetic relationships support the initial assumption of a. Yanevich that Buran Kaya III represented an early Gravettian stage. 11/14

The Buran Kaya III individuals were most closely related to later individuals from Western Europe associated with the Gravettian culture, in particular those of the Fournol cluster. 10/14

They shared also ancestry with individuals from the Caucasus suggesting that this Out of Africa wave used this route to Eurasia. 9/14

In contrast to what was previously assumed, our analyses revealed that the Homo sapiens arriving after the Campanian-Ignimbrite eruption encountered survivors of the previous migration events and admixed with individuals related to the Zlaty Kun woman. 8/14

Even though the bones contained only traces of ancient DNA, using our improved aDNA lab procedures and thanks to the aseptic excavations, we could obtain enough genomic information to study 740 000 SNPs for comparison with previously obtained more recent and more ancient genomes. 7/14

We studied partial genomes of two tiny pieces of skulls that were collected aseptically in 2009 by Laurent Crépin. 6/14

Layers 6-1 and 6-2 yielded fragments of human bones dated around 37-36 000 years ago, body ornament made of mammoth ivory and various lithic artefacts that, according to Alexandr Yanevich, were reminiscent of later Gravettian assemblages. 5/14

The Buran Kaya III site was excavated by a Ukrainian-French team led by Aleksandr Yanevich and Stéphane Péan . Buran-Kaya III is a rockshelter located in Crimea (Ukraine). It provides an exceptional stratigraphic sequence extending from the Middle Paleolithic to the Neolithic. 4/14

This climatic crisis is associated with the end of the Neandertal and of the earlier Homo sapiens populations that arrived before as represented by the Zlaty Kun or Bacho Kiro genomes. 3/14

This period of 37-36 000 years is a key period to understand the peopling of Europe since it directly follows a major cold climatic crisis, the Heinrich 4 stadial that was accompanied by a super-volcano eruption of the Campi Flegrei near Naples, known as the Campanian-Ignimbrite eruption. 2/14

The paper from our team at @IJMonod on the #paleogenomic #aDNA analyses of two 37-36 000 year-old humans from the Buran Kaya III site is out today in @NatureEcoEvo. I will take you through a short summary of the main findings. 1/14
