My main PhD work @monteirolab.bsky.social is now in @natecoevo.nature.com! We found a Hox gene promoter that helps butterflies🦋adjust their wing eyespots in response to seasonal temperatures🍃🍂, shedding light on the evolutionary origin of phenotypic plasticity. 1/9 www.nature.com/articles/s41...

Very excited to share that my first first-author pre-print is out today! Many thanks go out to all of our collaborators, especially those who helped with the fieldwork in Peru - it really wouldn't have been possible without you! 🦋

Evolution rarely invents from scratch.

Our recent study reveals that butterfly eyespots evolved by co-opting an ancient wing vein gene network. New trait, old genes. The study is now published in Communications Biology (featured: Jan26) www.nature.com/articles/s42...

Our eLetter github.com/caseywdunn/s... responding to a recent Science paper was just posted. The paper found more genes with consistent support for sponge-sister than ctenophore-sister. We found several technical issues that, when corrected, reverse the conclusions and recover ctenophore-sister.

Congrats @jeffgroh.bsky.social et al. Some avocado trees open female-phase flowers in the morning & then male in afternoon. Others show complementary pattern (m->f), to synchronize pollination of two types. Jeff show this to be a >45Mya polymorphism at a transcription factor across 100s of species.

GWAS has been an incredible discovery tool for human genetics: it regularly identifies *causal* links from 1000s of SNPs to any given trait. But mechanistic interpretation is usually difficult.

Our latest work on causal models for this is out yesterday:

Approaches combining genetic association and Perturb-seq data that link genetic variants to functional programs to traits are described.

Hi, I'm setting up a peer support platform for ECRs in ecology & evolution in China, aiming to address a huge problem --- academic burnout driven by hyper-competition and a system that often prioritizes elite background/title over actual research.

New #miRNA paper from Lai lab!! 🧬🔥

some think this field, despite recent Nobel to Ambros and Ruvkun, doesn't have much surprises left. but, do we EVEN KNOW WHAT a miRNA precursor LOOKS LIKE? we found some conserved miRNA hairpins up to 10x longer than suspected. this is mir-12, just bonkers! 1/n

Our work on the function of miR-51/miR-100 is out! miR-100 is widely conserved across eumetazoans but its function has been mysterious. Emilio Santillán found in worms it regulates signaling and extracellular matrix genes, some of which seem to be conserved targets! www.science.org/doi/10.1126/...

Music to my ears. This is brilliant. Either 90% of us can claim to be better musicians than Beethoven or… maybe just maybe polygenic scores aren’t perfect?
If someone you know buys into claims about "genetic optimization" of embryos using polygenic scores of cognition, just send them our 2024 paper on Beethoven & musicality. We wrote it to help communicate limits of individual-level genetic predictions & complexity of links between DNA & behaviour. 🧪👇
Notes from Beethoven’s genome
Wesseldijk et al. compare the genomic information collected from Ludwig van Beethoven with population-based datasets used to quantify musical achievement.
