First pre-print from the lab, a collaborative effort led by Jess Bourn @bournsupremacy.bsky.social, a fantastic PhD in my group. We resolve a key problem in development + evolution: how do we quantify heterochrony and link temporal variation to phenotype? www.biorxiv.org/content/10.6...

Quantitative mapping of heterochrony to species-specific phenotypes

The genetic program of animal development is conserved, but its rate of execution varies across species. Heterochrony, shifts in the relative timing of developmental events, generates phenotypic varia...

And it's out indeed! Huge congrats to @josanesousa.bsky.social, @gabrielalima19.bsky.social, @perezlouise.bsky.social & Hannah Schof! A true tour-de-force that highlights how emerging model systems can shed new light on long-standing macro-evolutionary questions. Go #axolotl, #polypterus #zebrafish!

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

Why are some species smaller than a paperclip while others grow longer than a school bus? How is body size evolution governed in animals? Out now in @pnas.org we tackle these longstanding questions through a genetic lens using my favorite group of fishes as our model!! www.pnas.org/doi/10.1073/...

Parallel shifts in differential gene expression reveal convergent miniaturization in fishes | PNAS

Body size variation in vertebrates is a complex polygenic trait, tightly correlated with numerous aspects of a species’ biology, ecology, and physi...

👻 G-g-ghost? Nope, s-s-snailfish! 🤍 Meet the mesmerizing new addition to our Into the Deep/En lo Profundo exhibit, rough snailfish! These ethereal charmers live in the benthic zone, a scientific term for the seafloor.

Update of our preprint on Inter-individual gene expression variability in fishes! We improved statistical analyses of continuous variables, and especially added machine learning on promoters which confirms cis-regulation of organ-specific expression variability. www.biorxiv.org/content/10.1...

Inter-individual gene expression variability implies stable regulation of brain-biased genes across organs

Phenotypic variation among individuals plays a key role in evolution, since variation provides the material on which natural selection can act. One important link between genetic and phenotypic variat...

We take for granted that our hands have two sides and can articulate in an endless number of ways. But what about a fish’s fin? Can a fish know something “like the back of its fin,” or have its future told with a fin palm reading? Check out this bluetorial to find out 👇🧪🧬🐟 doi.org/10.1101/2025...
