A recent study analyzed the DNA of 302 feral dogs living near the Chernobyl Nuclear Power Plant, finding remarkable differences between these dogs and those living 10 miles away. However, it does not prove that radiation is the cause of these differences.
The Chernobyl Nuclear Disaster and Its Impact on Feral Dogs
Background on the Chernobyl Exclusion Zone (CEZ)
The Chernobyl nuclear disaster occurred on April 26, 1986, when a massive plume of radiation was released into the sky. As a result, a large area around the power plant, known as the Chernobyl Exclusion Zone (CEZ), remains uninhabited by humans.
Feral Dogs in the CEZ
Thousands of feral dogs have thrived in the absence of humans within the CEZ. These dogs are descendants of pets left behind during the speedy evacuation of the area so many years ago.
Studying the DNA of Feral Dogs
Scientists from the University of South Carolina and the National Human Genome Research Institute have begun examining the DNA of 302 feral dogs found in or around the Chernobyl Exclusion Zone (CEZ). Their results were published in the journal Science Advances.
Key Findings
The study compared the DNA of these feral dogs to those living 10 miles away and found remarkable differences. However, it does not prove that radiation is the cause of these differences.
Implications of the Study
The study provides an important first step in analyzing these irradiated populations and understanding how they compare to dogs living elsewhere. While this may seem to imply that these dogs have undergone some type of rapid mutation or evolution due to radiation exposure, further investigation is needed to confirm this hypothesis.
