The Chernobyl nuclear power plant accident is one of the serious nuclear disasters in the world. 36 years later, the "mutated" black frog spawned nearby.
The frogs found in this area, called the Orientalis, usually have bright green skin, but now many frogs have dark or colored skin.
, a study published in the journal Evolutionary Applications, elaborates on the evolution of these frogs in detail. Scientists believe that darker skin may help frogs survive in high-radiation restricted areas.
Experts say: Melanin can protect the body from different types of radiation, whether it is ultraviolet, ionizing radiation or nuclear radiation from Chernobyl . From 2017 to 2019, researchers collected more than 200 male frog specimens from about 12 different breeding ponds, with varying radiation levels in these ponds. In the 10,000 square miles of quarantine, the frog's skin color is much darker than outside the quarantine. However, today's radioactive sites have no connection with the black frog population.
Darker frogs have a higher chance of survival in the 1986 disaster, meaning that the fittest's natural choice for survival, which may help them thrive and dominate the forbidden zone.
In this case, they should survive and reproduce better than normal green frogs. Over time, frogs have been breeding for 10 to 12 generations, which will result in these black frogs dominating the restricted area. "Further research is needed to identify potential mechanisms and evolutionary outcomes of the patterns found here," the researchers added.
