Chornobyl's wild dogs show genetic signs of directional selection, NC State reports
Research highlighted by North Carolina State University finds that genetic differences in Chornobyl's wild dogs likely reflect directional selection rather than mutation.
Why it matters: Researchers studying the Chornobyl dogs and other isolated dog populations now have a finding that attributes genetic differences to selection rather than mutation.
North Carolina State University's newsroom reported on 28 October 2026 the latest research on the wild dog population living in Chornobyl.
According to the university, the research compared these dogs with other dog populations that are similarly isolated and found genetic differences between them.
The university said those genetic differences are likely evidence of directional selection, not of mutation.

Scientists working on the Chornobyl dogs are directly affected: if the differences reflect directional selection rather than mutation, as the university reports, then explanations of how this population differs from other isolated dogs centre on selection.
