In the immediate aftermath of the Chernobyl disaster, residents were evacuated, leaving behind homes and pets. The dogs that once lived with families were suddenly abandoned, thrust into a wild and radioactive environment. Over time, these domestic dogs became feral, forming packs to survive. Restricted by the boundaries of the exclusion zone, these canines became an isolated population. With limited human intervention, they adapted to the unique challenges of their environment. This isolation has provided scientists with a rare opportunity to study evolutionary changes in a controlled yet natural setting, shedding light on the resilience and adaptability of these remarkable animals.
