Evolution in the Shadow of Disaster. Dogs from Chernobyl Have Extraordinary Genetic Traits

Forty years after the Chernobyl disaster, hundreds of dogs live in the Exclusion Zone, descendants of pets left behind. Genetic studies reveal these dogs differ from those in less contaminated areas, suggesting potential evolutionary adaptations. Researchers found genetic changes linked to disease resistance and cell function, indicating survival traits may have developed in response to the harsh environment. This case highlights evolution in extreme conditions and opens new avenues for understanding environmental contamination's effects on living organisms.
