The quest for the #Magnificent8 continues! This time, in search of Freship1 and Freship2 in Lago de Sanabria. See Marina, Alicia, and Rubén in action!
Thanks to Antonio from proyectoagua; Juan and David from Europarques & many others!

How did organs originated in the evolution of multicellularity? Despite their obvious importance, we still lack a theory of evolutionary organogenesis. Here's a @cp-trendsecolevo.bsky.social paper on how the placenta can offer answers @multicellgenome.bsky.social www.researchgate.net/profile/Oliv...

The real drama of life happened "backstage" in the unicellular world. 🎭🧬 #protistsonSky
Our postdoc Vika Shabardina is co-organizing this symposium with Annia (@ankarn.bsky.social). Two brilliant minds leading the evocell way!
Plus, a talk by @vikramalva.bsky.social. 👇

New preprint out! Using ~75k environmental OTUs + 77 fossil calibrations, we reconstructed a Proterozoic timeline of eukaryote evolution. Our results show crown eukaryotes were already diversifying >1.6 Ga, long before the first undisputed fossils (~1.05 Ga).

Are you very busy but still want to learn what Aphelids are and why they are important to understand the evolution of Fungi?
Then check out our “Quick guide” on Aphelids published in collaboration with @deemteam.bsky.social, Sergey and Guifré. #protistsonsky

Thrilled to see choanoflagellates can glide! I think this provide further support to the stunning complexity of the unicellular ancestor of animals, as we have been proposing. Congrats @thibautbrunet.bsky.social ! very nice work. #AnimalOrigins #choanos #multicellularity #protistsOnSky

More on the ancient foundation of animal development. Coyle & King illustrate how core regulatory modules were present in our pre-animal ancestors. The key was not invention, but recycling & new protein interactions. #CellBiology #multicellularity #protistsOnSky

Congrats Haillot & the whole @ulrichtechnau.bsky.social lab! Another brilliant example of how we shouldn't assume simplicity in non-bilaterian animals. Triploblasty’s roots seem to run older than we thought! Nice to see a crosstalk between MAPK, β-catenin & Notch to define identities. #EvoDevo
ulrichtechnau.bsky.social ulrichtechnau.bsky.social @ulrichtechnau.bsky.social · Aug 29
Finally, the excellent postdoc work of Emmanuel Haillot is out, where he dissected the integration of Wnt, MAPK and Notch signaling in defining mesoderm and endoderm identities in the diploblast Nematostella. Strikingly similar to sea urchins. www.nature.com/articles/s41...

🚀 Watching Núria Ros-Rocher grow from PhD student to independent @cnrs.fr researcher has been a joy. Talent + grit + kindness = 🔥. Huge congrats, Núria—and kudos, Thibaut. And I know this is just the beginning! Can’t wait for the next C. flexa chapters!
thibautbrunet.bsky.social Thibaut Brunet @thibautbrunet.bsky.social · Aug 30
A thousand bravos for Núria Ros-Rocher, who just secured a permanent @cnrs.fr researcher position in our lab. These positions are (too) rare but give much-needed job security to young scientists and allow long-term projects. Núria will dive deep into the natural history of C. flexa 🧪🌊 #ProudPI
