A real pleasure to meet George Clarke and hear about his experiences growing up on a council estate. We both know the positive impact social housing can have on families’ lives.
That’s why I’m determined to continue delivering more council homes as we build a fairer London for everyone.

toucan mimicry is cool
What do you get when you combine community science, tropical birds, and hardcore genomic methods? Jon Merwin’s talk at #SICB2026 ! Jon studies how convergent evolution evolves through model and mimic toucans. In addition to comparing phenotype and genotype, Jon developed an original R package (1/2)

Two-way native-invasive introgression and structural variants in invasive moth species. Admixture and exchange of adaptive alleles can facilitate adaptation, but this is also true for pests. Amazing work by @henrylnorth.bsky.social, @chrisjiggins.bsky.social and others, with a lot to think about.
I got to think about lots of cool/scary things working on this: (very) rapid adaptation, introgression of structural variants, invasive species, reproductive isolation, pesticide resistance, the precarity of food production. Grateful to have worked on such a big dataset with amazing collaborators

"hybridisation has combined H. armigera adaptation to soy with H. zea Cry1Ac resistance, with global consequences for food security. Thus, the collision of genomes can drive rapid anthropogenic adaptation via combinatorial evolution."

"hybridisation has combined H. armigera adaptation to soy with H. zea Cry1Ac resistance, with global consequences for food security. Thus, the collision of genomes can drive rapid anthropogenic adaptation via combinatorial evolution."
We actually predicted this rather scary scenario in the grant proposal written BEFORE it happened. And then documented the evidence as the Bt resistance allele spread in Brazil during the grant.
In short, a new pest now shares the tolerance of Bt toxins from H. zea with the ability to feed on soybean from H. armigera - a novel and potentially destructive combination of traits

One dramatic advance in evolutionary biology over the past 20 years has been the empirically lead shift in thought, away from rigid species boundaries towards introgression being very common, much of it adaptive. The ramifications are still rippling out (e.g. in ConBio). Below is a nice addition:
