"No evidence of transposable element bursts in the Galápagos Scalesia adaptive radiation despite hybridization, diversification and ecological niche shifts"
https://mobilednajournal.biomedcentral.com/articles/10.1186/s13100-025-00362-z
🔍 Despite rapid speciation, niche shifts, & hybridization, we found no significant TE accumulation differences across species or hybrids.
🌵 Even in arid-adapted lineages—where genome downsizing may be expected—TEs didn’t decline.

"#Cichlids exhibit differing degrees of curiosity. The cause for this lies in their genes. This trait influences their ability to adapt to new habitats... curious individuals can inhabit different areas compared to more cautious conspecifics."
The fitness landscape of a community of Darwin’s finches
Basically confirms and expands on Darwin's understanding of adaptive radiation in Galapagos finches in real-time. Adaptive radiation is the idea that a population, in an environment with varied unoccupied habitats and resources, can relatively quickly diverge into many new species.

My lovely friend whatsapped me this morning to say they’d come across me in a book they were reading and now I feel like a real scientist, thank you Jeffrey McKinnon #cichlids #adaptiveradiation #botswana #paleolake
