New preprint: 338 coleopteran genomes reveal exceptional rearrangement variation compared to other insect orders. Big congrats to @arf-mln.bsky.social, for getting this giant piece together. Big collaboration of @joanameier.bsky.social's and my groups. 🧵👇 doi.org/10.64898/202...
Phylogeny of 338 species with tips painted by the chromosomal ancestry of their contemporary genomes (well separated colours indicate only few changes, while blending indicates rearrangements). Colouring of the branches is by the number of rearrangements. The ring between paints and phylogeny indicates wether the chromosomal rearrangement was fusion dominated (brown) or fission dominated (teal) process.

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: www.nature.com/articles/s41... A short🧵:

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

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants
