Submission reminder! @JeremyChoin and I invite participation in our @SAfAarchaeology session "The ancient DNA revolution in Africa: New data, broader applications, and evolving research practices." Please reach out if you want to know more! Abstract submission deadline Jan 31.
Do you love #ancientDNA, #Africa, and beautiful beaches?. Submit a talk to “The ancient DNA revolution in Africa: New data, broader applications, and evolving research practices” session that I'm co-chairing with @JeremyChoin at the 2025 @SAfAarchaeology meeting in Portugal!.

A huge contribution to the #ancientDNA world! 7,000 y.o. genomes give new insight into a North African "ghost" lineage, show limited gene flow from sub-Saharan to Northern Africa despite a "green Sahara", and exhibit low amounts of Neandertal ancestry. Hope to see more of this!.
I'm beyond excited to share our new paper in Nature! We sequenced the first ancient human autosomal genomes from the Central Sahara, two ~7,000-year-old individuals from Takarkori in Libya, revealing a long-isolated North African lineage: Short thread: 1/n.

"It’s the first time we have a genetic picture unifying all Indo-European languages" -@iosif_lazaridis .🧬💀🐴.
Our papers, out today in @nature, show how ancient DNA from the Eneolithic and Bronze Age steppe points to a North Pontic origin of the Indo-European language family and a Caucasus-Lower Volga (CLV) origin of Indo-Anatolian (inclusive of the now extinct Anatolian languages). 1/
