Thanks Luca!

Amazing peppered moth story from Saccheri lab - same locus, but different structural variants, underly parallel evolution of industrial melanism in the UK and across continental Europe.

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.

Causal modelling of gene effects from regulators to programs to traits - Nature Approaches combining genetic association and Perturb-seq data that link genetic variants to functional programs to traits are described.

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:

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.

We found a novel promoter of a Hox gene promoting adaptive temperature sensitivities across a large clade of butterflies. This highlights the essential roles of novel cis-regulatory elements in fueling adaptations on a macroevolutionary scale. 8/9

In B. anynana, disrupting this novel promoter reduced the butterfly’s ability to adjust eyespot size with temperature, showing that this genetic element contributed to the evolution of temperature-mediated eyespot size plasticity in satyrid butterflies. 7/9

How is Antp activated in eyespots of a specific clade of butterflies? We found a genetic switch, a promoter, that evolved specifically in satyrid butterflies, and it activates Antp expression specifically in eyespot central cells. 6/9

Disrupting Antp in two satyrid butterflies reduced eyespot size, especially when the insects were raised at warmer temperatures, confirming Antp’s role in boosting the levels of eyespot size plasticity. 5/9

From the tissue-specific transcriptomic data, we pinpointed a Hox gene Antennapedia (Antp), showing higher eyespot expression levels at warmer temperatures. Notbly, among all butterflies with eyespots, Antp is only activated in the eyespots of satyrid butterflies. 4/9

How did satyrid butterflies evolve such temperature sensativities? In a model satyrid Bicyclus anynana, we profiled gene expression from both eyespot and non-eyespot developing wing tissues across two temperatures, using laser-microdissection. 3/9

Many tropical satyrid butterflies look strikingly different in different seasons. In the hot wet season, these butterflies develop large eyespots on their wings. In the cold dry season, these eyespots are small. This change enhances their survival in each season. 2/9
