The August 29th publication of the study in the journal Evolutionary Applications, found the eastern tree Frogs (Hyla orientalisFrogs with darker skin tones were more likely than those with lighter skin to survive the 1986 Ukrainian nuclear accident. This led to a population of darker frogs today.
In a blog post, researchers stated that radiation can damage living organisms’ genetic material and cause undesirable mutations. The ConversationMore information about their research.
“However, it is one of the most fascinating research topics in ChernobylThe purpose of this study is to see if radiation can be used to adapt some species. As with other pollutantsRadiation could be a strong select factor that favors organisms with survival mechanisms in radioactive areas.
The Chernobyl nuclear power station in Ukraine was hit by an explosion on 26 April 1986. Radioactive material was released over an 18-mile (30 km) radius.
“The Chernobyl accident released approximately 100 times the energy released by the nuclear bombs of Hiroshima and Nagasaki,” Pablo Burraco, the study’s lead author and a biologist with the Doñana Biological Station in Seville, Spain, told Live Science in an email.

After the disaster, officials moved residents out of the affected zone and created an exclusion zone covering 1,040 miles (2,700 kilometers). This abandoned area has since been transformed into a wildlife refuge.
Burraco and his colleagues wanted to know how the nuclear meltdown influenced evolution in the animals that lived there.
Burraco explained that more than 200 male radioactive contamination frogs were studied. Their habitats were located in 12 different breeding ponds.
“We believe the best explanation is to [why]Chernobyl Exclusion zone frogs [are changing color]”The accident occurred at extremely high radiation levels, making it difficult for frogs of dark skin to survive.”
Why do you have dark skin? The high levels of melanin in frogs is the main reason. SkinThey were shielded from radiation
Burraco stated, “Melanin has been shown to protect against radiation as it can mechanically avoid producing free radicals due to the direct impact radioactive particles on cells.”
Radiation can cause oxidative stress, which can damage vital structures necessary for life like the membrane of cells and even the heart. DNA.”
Lighter frogs’ cells were subject to higher levels of radiation which caused their death at faster rates than their darker counterparts. According to the study, dark frogs were more likely to survive after the blast.
Researchers also investigated potential negative effects of excess melanin in the post-Chernobyl frogs. Researchers found similar results in other species, such as certain types of fungiThe amphibians’ overall health was not affected by darker skin pigments. In fact, it helped to ionize radiation which stops ionized molecules getting into cells and causing damage.
Burraco said that melanin production can prove to be expensive.
“However frogs produce eumelanin which is the main melanin color and it seems to not incur any physiological cost.”
