🧠🦈Excited to present our latest work🧠🦈Interested in brain evolution? And shark embryos? Then read on… Our work sheds light on the deep origins of our brain’s most complex regions.

We are searching for an enthusiastic scientist to join our team and establish annual killifish as a model system for early developmental biology and biophysics! @embl.org @embldbunit.bsky.social Apply here: embl.wd103.myworkdayjobs.com/EMBL/job/Hei... Please re-post 🙏

John Philip Trinkaus, a student in the 1939 Embryology course, left us with his drawings of 'presumptive regions' in Trout, Fundulus, Dog fish, and Urodele; development of circulatory system of Teleost; and a squid spermatophore. bit.ly/4eZWxfU

Couldn’t agree more! Evolutionary perspective is a guiding principle for most projects in our lab.👇🏽

Last week I had the pleasure to visit beautiful Banyuls, run some fun experiments and enjoy the sea 🌞 ⛵ . Thanks @biom-banyuls.bsky.social for hosting me, especially bluesky-less Sylvie and Ronan 🦈 😊 and @hector-escriva.bsky.social

After 50 years, Jaws still shapes our view of sharks. @whysharksmatter.bsky.social spoke to Nature about how Jaws influenced the public perception of sharks and the importance of protecting marine life. 🎬 🌊 🧪

🚨 We’re recruiting PhD students! 🚨 Join the Stem Cell Biology and Evolution lab at @lsiexeter.bsky.social to study planarians, stem cells & evolution. 2 projects available - 1 week left to apply! Interested and no PhD yet? Apply now. Or help us spread the word! 🙌 www.exeter.ac.uk/research/ins...

"Try to identify what gives you energy and where your intrinsic motivation can be found" 😊. Good advice from @eveseuntjens.bsky.social

New paper from the lab: Our teeth arose as sensory organs on the outside of the body of ancient jawless fish.!! Congrats to Yara Haridy and the team! Background and video: phys.org/news/2025-05... Open Access Paper: www.nature.com/articles/s41... News and Views: www.nature.com/articles/d41...

I'm still processing all the amazing interactions and possibilities this meeting brought. Different fields and expertise converging in a common interest: brain evolution. It was fantastic. Thanks to the organizers @borrell-lab.bsky.social @k4tj4.bsky.social ( Nerea Moreno, Fernando and Zoltan)

We're hiring! Our lab is looking for a postdoc to investigate the #evodevo of #cephalopod brains. Did you recently graduate, and do you want to join our EU #WEAVE project with the Simakov and @simon-sprecher.bsky.social labs? Find the application form👇Thanks for RT 🐙🦑 www.kuleuven.be/personeel/jo...

It has been an absolute pleasure for our lab to attend #ECCN2025 for the first time this year. We had meaningful discussions and learned a lot from a vibrant community tackling tough questions on brain evolution and development! Super excited for what lies ahead!

Modern sharks as our best mirror to our jawed common ancestor – @idoiaeu.bsky.social talks about the catshark embryo as a model to study the origin and evolution of the vertebrate telencephalon at #ECCN2025 @borrell-lab.bsky.social @r3rt0.bsky.social @zoltan-molnar.bsky.social

Two days to speak at this interesting conference. Looking forward to exchange and keep learning about brain evolution. And share what sharks are teaching us! 🦈 🧠 eccn2025.umh.es

New Pre-Print Alert! "Teeth Outside the Jaw: Evolution and Development of the Toothed Head Clasper in Chimaeras." We use fossil evidence, development and CT scans through ghost shark ontogeny to describe the emergence of the tenaculum! 👻🦈🦷 @karlycohen.bsky.social www.biorxiv.org/content/10.1...

Always a pleasure to go diving in the cold but vibrant waters of Galicia‼️ 🦈🐟🐙

Amazing! So much still to explore about these incredible beings

The beauty of embryogenesis. Can you see the blood flowing in rhythm with the heartbeat? #sharkembryo 🦈

Time to apply to the DevBio summer school at EMBL Heidelberg! Hands on and interdisciplinary!

This is a lovely paper that I handled at @plosbiology.org, showing that our nifty synovial joints were already there in the common ancestor of jawed fish. Thanks to @ucsdcooperlab.bsky.social as AE, and to first author @neelimasharma.bsky.social for this stunning pic of a little skate pelvis!

Soo looking forward to this one! :) Registration opening soon

🪱 Platynereis dumerilii is a marine worm that offers important insights about evolution. Scientists from EMBL Heidelberg's Arendt Group follow this species across time and space, to construct the first atlas with cellular resolution for the whole animal. 🧪 #evolbiol www.embl.org/news/science...

A reminder: for genotypes to produce phenotypes, they have to go through development

This is the face of a shark! I've stained the mineralised tissues to show that their teeth and scales are both made of the same enamel-like material 🦈 🦷 🧪

The Kibwezi Forest, one of Kenya’s last groundwater woodlands, is a lifeline for wildlife & local communities. With the Kenya Forest Service, we’re protecting this unique habitat, which is home to Umani Springs: a critical water source for residents of Kibwezi town, as well as our orphan elephants.
