Evidence of sheeppox in 17th-19th century France: a multi-disciplinary investigation of a sheep mass mortality assemblage Epizootic outbreaks posed major threats to food security, economic stability, and animal welfare in past communities. While these events and their impacts are well documented in historical records, ve...

Despite my insomnia, I'm very happy to share our preprint: a multi-disciplinary assessment of a sheep mass mortality event from ~18th century France. We report the first ancient sheeppox virus (think smallpox) and the Taenia hydatigena (nasty roundworm) genomes.

Lovely is the right adjective. Writing this was so enjoyable in the company of @acstone.bsky.social @blevinske.bsky.social and Verena Schuenemann. Hope you enjoy.

Homo sapiens-specific evolution unveiled by ancient southern African genomes - Nature The genomes of 28 ancient southern African individuals dated to between 10,200 and 150 years before present offer insights into the evolution of Homo sapiens.

Our new ancient DNA paper has just been published!
We present 28 new genomes from southern Africa - several of them high-coverage whole genomes.
Exciting to be moving towards population-level representation of ancient southern African genetic diversity!

The MUC19 gene: An evolutionary history of recurrent introgression and natural selection We study the gene MUC19, for which some modern humans carry a Denisovan-like haplotype. MUC19 is a mucin, a glycoprotein that forms gels with various biological functions. We find diagnostic variants ...

An extraordinary story of archaic introgression🧬: a Denisovan haplotype, introgressed through Neanderthals, selected in the Americas, and linked to an expanded copy number of a tandem repeat.
