Interested in goats 🐐? Read our pre-print on ancient Irish goats and their connection to the Old Irish goat breed

Just look at this dashing individual, courtesy of the Old Irish Goat society

Old Goats: 3,000 years of genetic connectivity of the domestic goat in Ireland The domestic goat likely first arrived to the island of Ireland as part of the introduction of agriculture approximately 5,900 years ago, and remains a part of the island's biocultural heritage. Howev...

Very happy to see our pre-print on ancient Irish goat genetics on bioRxiv #aDNA #spiergorm

I want to acknowledge this was only possible through the work of the late Dr. Judith Findlater, along with Prof. Eileen Murphy at @qubelfastofficial.bsky.social.

Duncan ha recreado todo lo que cargaba Ötzi, el hombre encontrado momificado en los Alpes (video de @pakozoic.bsky.social aquí: www.youtube.com/watch?v=sSlz...) a escala de Playmovil. Creo que este es mi hilo favorito en todo BlueSky.

Postdoctoral position in Population Genomics - Uppsala University Postdoctoral position in Population Genomics, Department of Organismal Biology, Uppsala University

I have funding for a 2-year dry-lab postdoc to join our team @humanevouu.bsky.social 🧪 (Deadline Oct 21st)

The project will utilize modern and #aDNA data from humans and sheep to study environmental adaptation (including method development and simulations).

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.

Awesome news!!! Congrats Kevin!!

What a week! 🎉 Big thanks to @isba11.bsky.social for hosting an incredible ISBA conference — so well organized and full of great science.

Columbian mammoth mitogenomes from Mexico uncover the species’ complex evolutionary history Paleogenomic studies suggest that Mammuthus columbi derives from an ancient hybridization between Mammuthus primigenius and Mammuthus trogontherii. While its habitat spanned from North to Central Amer...

Thanks to all collaborators, you were key to this success! See below a fantastic note covering the paper by the great @rpocisv.bsky.social 👇

The science is amazing and what’s even more impressive is Ice lollies at #ISBA11 💕💕💕 😂😂😂

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!

Contact me at kevin[at]palaeome.org, full ad to come. Please share!

ISBA11 starts tomorrow, and we have just one question for you... are you ready for it?

The genetic history of the Southern Caucasus from the Bronze Age to the Early Middle Ages: 5,000 years of genetic continuity despite high mobility Ancient DNA from the Southern Caucasus reveals remarkable genetic continuity, with some mixing from Anatolia/Iran and the Eurasian Steppe, and shows that even periods of urbanization and increased mob...
