Chernobyl plant dogs show selection signals, researchers say
A Genes study, described by Wired, finds genomic signs of directional selection in dogs at the Chernobyl plant versus nearby city dogs, without proving radiation caused the differences.

Dogs living at the Chernobyl Nuclear Power Plant show genomic patterns consistent with natural selection rather than chance alone, according to a study in the journal Genes described by Wired1.
Researchers compared DNA from dogs around the plant with dogs in Chernobyl city, about 16 kilometers away, and with other dog populations, Wired reported1. The comparison, Wired said, suggested random chance could not explain the differences1.
Some of the strongest signals sat near genes involved in DNA repair, immunity and cell survival, Wired reported1. The paper does not show which environmental factor favored those variants or whether they confer an advantage1.
Radiation is one possibility, but the study could not separate its effects from other contaminants or from the animals' history, Wired reported1. A paper in Genes by Megan Dillon, Matthew Breen and colleagues at North Carolina State and partner institutions, published 27 September 2026, reports evidence of directional selection in free-breeding dogs near the plant and notes the lack of historical specimens from 19861.
The plant dogs are described as descendants of pets left during evacuations after the 1986 accident, Wired said1.
