Museum Genomes Reveal Ecological Shifts

Updated: 2026.05.13 5D ago 1 sources
Extracting whole genomes from old museum specimens (museomics) can expose rapid, recent evolutionary transitions—such as a fruit fly shifting from rotting‑fruit detritivore to aquatic predator—by revealing gene loss, intensified selection on remaining sensory genes, and matching morphological specializations. These results show that natural‑history collections are living archives for reconstructing recent adaptive change and ecological loss when field sampling is impossible. — If museum genomes routinely expose recent adaptive or extinction‑linked changes, they reshape conservation priorities, how we interpret biodiversity loss, and the legal/ethical value of collections.

Lund University and Université Paris Saclay recovered a complete genome from a 40‑year‑old Drosophila enhydrobia specimen and linked genomic changes (reduced chemosensory gene counts with intensified selection on the remainder) to aquatic, predatory larval morphology (≈100 spiracle openings, hooked pads) reported in Current Biology.
