Scientifically, a raven has 17 primary wing feathers, the big ones at the end of the wing. They are called pinion feathers. A crow has 16. So, the difference between a raven and a crow is only a matter of a pinion.

Happy #WorldPeatlandsDay! 😍

I'm very excited to take part in the workshop 'Lineages, Complexity, and Evolution' at the Universidad de Oviedo. I'll be presenting a paper that Pierrick Bourrat and I have been working on. Looking forward to engaging with some fantastic philosophers of biology.

It is publication day for The Organism-Environment Pairing (@mitpress.bsky.social)! This 📗 has been deeply formative for me as a scholar, and it owes so much to so many wonderful people. I truly hope it finds many readers! mitpress.mit.edu/978026205282... #booksky #philsci #histsci #philsky #evosky

In the upcoming year fight for a new world and a life worth living

“The ultimate, hidden truth of the world is that it is something that we make, and could just as easily make differently.” ― David Graeber
