The old Irish goat is a living link to Ireland’s Bronze Age Study shows distinct breed has genetic links to goats that lived in Ireland 3,000 years ago

Our work on ancient Irish goat was covered in the Irish Times.

Phylogenetic and dating analysis of ancient and modern sheeppox virus. A. Maximum-likelihood phylogeny of ancient and modern SPPV genomes with ≥5× coverage, rooted using LSDV and GTPV. Nodes with bootstrap support of 100 are indicated by blue circles; other bootstrap values are shown at the corresponding nodes. Clades composed exclusively of modern genomes are collapsed and shown as triangles, and branches corresponding to ancient genomes are highlighted in pink. The grey box delineates the SPPV clade. B. Maximum-likelihood phylogeny of SPPV genomes with placement of low-coverage ancient samples using PathPhynder (Martiniano et al., 2022). For clarity, only the SPPV portion of the phylogeny is shown. Samples are coloured by material type, and low-coverage genomes (<5×) placed using PathPhynder are indicated by red triangles. Nodes with bootstrap support of 100 are marked with blue circles; other values are shown at the corresponding nodes. Tip labels indicate sampling location and calibrated historical date. Host species, sequencing coverage, and sample age are shown as a heatmap adjacent to the tips. C. Time-calibrated Bayesian phylogeny of the SPPV clade, with samples coloured according to material type.

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.

Inferring Domestic Goat Demographic History Through Ancient Genome Imputation Abstract. Goats were among the earliest managed animals, making them a natural model to explore the genetic consequences of domestication. However, a chall

Our paper on imputation of ancient goat genomes is now available at GBE - congratulations to @jolijnerven.bsky.social #aDNA

Huge congratulations to Zhe and everyone involved! 😊

I will be recruiting two PhDs for my ERC Project HERDPATH - let's discover out how livestock and pathogens evolved together using #aDNA. Projects will be animal or pathogen focused but will be in dialogue.

Details at my quaint website below. Deadline 3rd October.

Palaeoproteomic and genetic insights into millennial-scale dairy consumption in Armenia Dairy products are a key component of the diet in Armenia today, yet the origins of milk consumption, its historical development, and genetic adaptations related to milk digestion in the region remain...

Our new paper shows how a multidisciplinary approach (ancient proteins + DNA) reveals the long history of dairy in Armenia! 🥛🐄

Shameless promotion from #isba11 - I'll be hiring PhDs to start early 2026 (plus postdocs starting later), using #adna to study livestock and pathogen coevolution, particularly looking at inbreeding and immune gene evolution!

Archaic ancestry inference in imputed ancient human genomes When modern humans expanded from Africa into Eurasia, they interbred with archaic hominins such as Neanderthals and Denisovans. This groundbreaking discovery, made in part possible through the genomic...

Turns out imputation of introgressed archaic regions in aDNA works really well — sometimes even better than for the rest of the genome. More on this (and other cool results) in our new preprint 👇 #aDNA #ArchaicIntrogression #imputation
