How a strange fruit fly became a bloodthirsty underwater hunter

Phys · · 484 words · By Lund University
Evolutionary Biology Genomics Museum Preservation

Researchers at Lund University used DNA analysis on a museum specimen to map the genome of Drosophila enhydrobia, a carnivorous fruit fly that lives underwater. The study, published in Current Biology, identifies genetic adaptations in the fly's sensory systems and emphasizes the scientific value of natural history museum collections.

“Using modern DNA techniques, the research team managed to extract and analyze an almost complete genome from an old, pinned specimen—without destroying it.”
VERIFIED
The Mirage News article confirms the use of DNA analysis of a pinned insect from a museum in Zurich. Additionally, a general web search result discusses the process of 'Sequencing Degraded DNA from Non-Destructively Sampled Museum Specimens', which supports the technical feasibility of the claim.
