🧵 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...

Two palaeogeneticists traveling to Northern Yukon's wilderness in search of extremely old DNA 🧊🧬🧪 A mysterious permafrost mummy hidden in the collections 🦴🕵️ An Agatha Christie book 📖 @gog1693.bsky.social behind-the-scenes story on his paper has EVERYTHING! Paper 👉 www.nature.com/articles/s41...

The mysterious mummified tissue found in the collections, nicknamed "Mr. Parker Pyne".Gonzalo sampling some specimen in Whitehorse collections.It was a porcupine!

As promised, what follows is a behind-the-scenes story of how we came across this permafrost-mummified tissue and tried to determine which species it belonged to.

How does development shape the variation evolution can act on? In our new paper in @pnas.org , we bridge developmental dynamics and quantitative genetics, linking dynamical models of phenotype formation with the statistical parameters used to study evolutionary change www.pnas.org/doi/10.1073/...

Phenotypic variation is the raw material for evolutionary diversification and adaptation. However, a critical gap remains in evolutionary theory be...

So happy to have the opportunity to do some public engagement with the Beringia Centre Science Talks at @yukonberingia.bsky.social ⬇️ I'll try my best to explain the challenges 🔍 of working with million-years-old DNA 🧬🦣 and what we can learn from it. Check our paper: doi.org/10.1093/molbev/msaf065

For my first-ever bsky post, I’m thrilled to share our latest #ancientDNA research, which I co-led with @jessthorpemas.bsky.social OA: doi.org/10.1093/molbev/msaf065 We recovered and analysed mitochondrial genomes from many #mammoths spanning the last million years 🦣🧬⌛ Check this 🧵 we wrote ⬇️

New paper 🧵 A team co-led by #cpgsthlm 's researcher @jcchacond.bsky.social has analysed DNA from a large number of mammoths across a million-year timescale 🦣🧬 The findings include the discovery and analysis of the oldest known woolly #mammoth in North America! 👉 academic.oup.com/mbe/article/...

Pictures of a woolly mammoth molar dated to 216kya. The earliest in North America.

We can't afford to take backwards steps. ❌ Soy producers must uphold the Amazon Soy Moratorium & protect the rainforest from irreversible damage. Weakening it could open up large areas of forest for animal feed. 🌎 theguardian.com/environment/... #Amazon #Rainforest
