Une pensée aujourd'hui pour l'anniversaire de la mort de notre collègue, mentor et ami, Michel Vervoort https://www.ijm.fr/hommage-a-michel-vervoort/
Hommage à Michel Vervoort - Institut Jacques Monod

Notre collègue, mentor et ami Michel Vervoort nous a quittés le 8 décembre 2022 à l’âge de 52 ans. Sa disparition laisse un immense vide auprès de tous ses collègues […]

Finally, for French-speaking readers, we summarized our finding in this article from @FR_Conversation . 14/14

Homo sapiens : comment deux crânes réécrivent l’histoire de son apparition en Europe – Nouvelle recherche

L’analyse génétique de deux fragments de crânes datant de près de 40 000 ans démontre que notre espèce a colonisé l’Europe depuis l’est et s’est métissée avec nos cousins néandertaliens.

None of this would have been possible without an amazing collaboration with Andy Bennett, @oguzparasayan and Eva-Maria Geigl and the Ukrainian-French archeologists team. Eva-Maria has contributed a behind the story blog about it. 13/14

Crimea’s place in Europe 36,000 years ago: a tale of ancient genomes

Persistence, hard work, and French-Ukrainian interdisciplinary collaboration enabled us to reveal, hidden in the genomes of two Upper Paleolithic people from Crimea, the story of the early peopling of Europe which continues to resonate in the present.

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 Alexandr Yanevich that Buran Kaya III artefacts 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
