Big takeaway #4: Populations show strong genetic structure + long-term isolation → widespread incipient speciation ➡️ Many “species” may contain multiple lineages ➡️ Conservation should treat populations as distinct units It was a big team effort—thanks to the many wonderful co-authors 🙌

Big takeaway #3: Selection acted on different targets within a particular repeated leaf developmental regulatory network (adaxial–abaxial polarity), not on a single “master” gene. ➡️ Multiple entry points into the same phenotype ➡️ Consistent with network/“omnigenic” architectures

Big takeaway #1: Adaptive radiation doesn’t always require lots of new, de-novo mutation. Despite large their phenotypic diversity, different species not strongly differentiated. Evolution repeatedly drew on overlapping genetic variation during Scalesia’s rapid diversification.

We have a new paper out on one of evolution’s “classic” systems: Galápagos Scalesia plants! 🌿 How do you generate huge differences in leaf shape across species in <1 million years? We combined genomics + morphology + transcriptomics across the full radiation 👇
