This year, the annual symposium of my Chaire @college-de-france.fr will be on The Evolution of Developmental Mechanisms. An impressive lineup of speakers and weirds animals, including humans. Free entrance and coffee breaks. Come, have a seat, relax and enjoy the best possible basic science🤘RT🙏
This Thursday! 🐓🐁
A black and white photo of two trout missing their dorsal fins, taken in 1936.
In 1936, a U.S. Forest Service ranger was fishing high in the Utah mountains when he found something bizarre:
Cutthroat trout with tiny - or missing - dorsal fins! 🧵

Happy to share the version of record, published in Nature communications yesterday!
Big news from @evodevopanam.bsky.social 🤩
⭐️EvoDevo Mondays⭐️
This session will be chaired by the one and only Natalia Pabon Mora from the Universidad de Antioquía, Colombia. And as speakers, @luiza-o-saad.bsky.social and Joao Botelho (both originally from 🇧🇷)
Stay tuned for the link!

Join us this next Friday *the 13th* 👻 👻 to hear us talking about bones and cartilages in development and evolution 🐟 🐠 🦴
🐟👀 SFSU Biology seminar — Thu Mar 5
2–3pm | SEC 116
Dr. Patricia Schneider (LSU): “Split Screens: Exploring Vision through the Eyes of the Four-Eyed Fish.”
Student time: 3–3:30pm. Come by!
Super excited about these results and new system.
Mapping, Expression, Loss-of-Function
I'm floored by how this locus seem to integrate all the spatial info to sketch the minute details of the phenotype, and how this is prone to evol tweaks

Neil H. Shubin has been elected as the next NAS President! A leading evolutionary biologist and science communicator, Shubin will succeed Marcia McNutt on July 1. The Academy also named Cherry Murray as International Secretary and elected new councilors. Read more: www.nasonline.org/news/2026_pr...
🧪🔬🧬Beautiful work! Many people have long wondered what the impact of actinodin loss would be on fin development.

It’s out! 🐟 We compared three regeneration superstars—axolotl, zebrafish, and Polypterus—to ask how animals regrow limbs and fins. We find shared core processes, and other programs fine-tuned by evolution in surprising, lineage-specific ways. tinyurl.com/mpftkn7y
@pbs.org has had my whole heart since I was little little, so it is very surreal to be writing for a PBS Digital Studios show! Here is my first episode of Be Smart:

Thank you @drjoehanson.bsky.social & team! My nose knowledge now knows no bounds 👃
Very happy to share that this paper is now online on @currentbiology.bsky.social !! 🥳🧪 Check out the final published verion here: www.cell.com/current-biol...

The talks (in english) can be accessed from the @college-de-france.fr website. A great journey through ‘Our ancestors the fish’, from 380 Mio years ago to their hidden presence inside ourselves. Lessons #1 and #2 👇🏼

Pretty stoked that our article got the cover of the latest issue of @journalofanatomy.bsky.social!

Extremely cool to see very different systems potentially point to similar genetic constraints or developmental biases leading to morphological variation. Now we need a fish example!
How do four-eyed fish see above & underwater? 🌤️🌊 Our new preprint reveals how Anableps rewired its retina for dual vision- evolution at work 👁️👁️ Kudos to @perezlouise.bsky.social @josanesousa.bsky.social @keylapruett.bsky.social + team!

Happy to have contributed to this big story. We present new genome assemblies, genus-wide complementation and allele-specific expression analyses in hybrids between zebrafish and closely related Danio species with divergent pigment patterns. A vertebrate model genus for basic comparative biology.
UMAP of single nucleus RNAseq dataset of Polypterus fin regeneration
Hey Regen folks 👋 Excited to share that our single-nucleus RNA-seq dataset for Polypterus fin regeneration is now live at the Broad Institute portal! Dive in here: tinyurl.com/5bck22jx
Big thanks to the team for making this happen—looking forward to seeing what you all discover!
The regulation and evolution of proportion is a classic challenge in biology. This is exciting work into the genetic and developmental basis of proportionality using a very cool model. Congrats Ceri! 👏🧪🧬🐭
Vertebral skeletal diversity in mammals is remarkable. How do the differences between vertebral size and shape develop and evolve? See how we tackled this question in our paper published in @natcomms.nature.com today!
Tomorrow wednesday October 15th at 11am, first seminar of @neilshubin.bsky.social , guest Professor @college-de-france.fr on ‘The history we share with fish’. Come, have a seat and enjoy learning where we come from. Free knowledge, no registration🤘
🚨 🚨 Science alert on a #FluorescenceFriday; check my latest paper published in @genetics-gsa.bsky.social where I integrated comparative tissue-specific transcriptomics and speciation genomics to discover two novel craniofacial genes behind pupfish extreme jaw development! tinyurl.com/craniofacial...
