🧵 New preprint: Have you ever tried to perform molecular clock dating of ancient mitogenomes using BEAST? Have you struggled using manual tools to create your input files, run your analyses and extract your results? We hope our pipeline provides a solution to this: www.biorxiv.org/content/10.6...

MitoDate: a Nextflow pipeline for molecular clock dating and phylogenetic inference using ancient mitogenomes

Summary Ancient DNA studies are increasingly targeting samples that are beyond the limit of radiocarbon dating (>50 thousand years old) and are often difficult or impossible to date using other geochr...

New paper (from my colleagues @cpgsthlm.bsky.social!) showing children in Viking-Age & Medieval Sweden were buried in gendered ways, but those buried together were rarely close biological relatives. A great example of how #AncientDNA sheds new light on childhood, kinship & social organization 🧬

Equal in death: Ancient genomic analysis of children’s early Christian burials

Ancient genomes challenge views of close kinship in multiple Christian burials, revealing flexible traditions around children.

A game board from the forum of Timgad (Algeria) is a more Roman spin on the trite ‘Live, Laugh, Love’ sign. Replacing hunting w/cheese & and I am in, y’all. ‘venari lavari / ludere ridere / (h)oc{c} est / vivere’: ‘to hunt, to bath, to play, to laugh — This is to live!’ (CIL VIII, 17938). 🛁

A famous board from the forum of Timgad, for instance, gives us an idea of fun pastimes in and around the city: ‘venari lavari / ludere ridere / (h)oc{c} est / vivere’: ‘to hunt, to bath, to play, to laugh — This is to live!’ (CIL VIII, 17938).

👀 Signet ring, said to come from Archanes, Crete, Late Minoan 1450-1375 BCE. Gold, bezel 3.4 x 2.2 cm, max. inner hoop diam. 1.85 cm. AN1896-1908.AE.2237 See Alt for details.

Bull-leaping is one of the most enduring images from the Aegean Bronze Age. This image features on frescoes and objects from the Palace of Knossos and could be linked with the passing down of the myth of the Minotaur.
This incredible signet ring dates back to 1450-1375 BCE. It shows an acrobatic man leaping over a bul, the paved floor indicates that this took place in or around the Palace.
See it on display in Gallery 20, Level G.

Excited to share our new paper in Communications Biology! We generated >1000 new complete mitochondrial genomes from understudied regions in sub-Saharan Africa, providing an updated overview of maternal genetic diversity and demographic history across the continent. www.nature.com/articles/s42...

🏺🧪Preprint of 1039(!) whole ancient human genomes from Britain, mainly dating to 1st Millennium CE, representing the best part of 7 years of my life. Herculean effort by @marinasdsilva.bsky.social to get this over the line. 'Migration Period' is more migrationy than we could have possibly imagined.

I'm sure they've done all the necessary statistical contortions to account for migration but, oh boy, I'm having a hard time believing time rise B is positive selection. It tracks the rise of Steppe-related ancestry to a tee! I'm barely able to follow the ms so surely I must be missing something.
