A new study from researchers in Ukraine and Poland reveals a significant change in the appearance and behavior of dogs living in war-torn regions of Ukraine. The research, which analyzed more than 750 dogs, found that the ongoing conflict is triggering a process described as a reversal of domestication, where the traits favored by humans for thousands of years are being replaced by those that enhance survival in harsh conditions. This trend suggests that dogs are adapting to their environment in ways previously unseen due to the war.

In combat zones, it appears that only the dogs best suited for survival are thriving, leading to a rapid form of natural selection characterized by high mortality rates that overshadow the factors typical of domestication, such as breeding success. This phenomenon not only highlights the resilience of these animals but also raises concerns about the broader implications of war on domestic species, as they may develop behaviors more reminiscent of their wild ancestors. The findings draw parallels with similar evolutionary changes observed in wildlife affected by other extreme environmental conditions.

As the conflict continues, the transformation of these dogs could have significant implications for both human-animal relationships and the ecological balance within affected areas. The study published by the New York Times underlines the urgent need for further research into how war impacts not only human lives but also the animals that share their environments, suggesting potential future changes in the breeds and behaviors of domestic dogs as they adapt to a reality shaped by violence and survival.
