It is like a childhood painting that when we used to make frogs on white paper, we used to fill many colors in it. It was funny to see different colored frogs in the pictures of children but the incident of Chernobyl nuclear leak has created mutant frogs. But the Chernobyl area’s frogs, which were exposed to radiation in 1986, are dark in color. And all because the typical green frogs simply turned black as a natural response to the catastrophic nuclear explosion !
The Chernobyl nuclear power plant’s fourth reactor was destroyed, causing the greatest radioactive element spill in human history, which had an impact on both the surrounding population and the environment.
Chernobyl has already grown to be one of Europe’s greatest nature reserves more than three decades after the accident. There are, bears, wolves, and lynxes are just a few of the many endangered animal species that call Chernobyl home. Even new species have been discovered !
How the Chernobyl nuclear crisis affected its wildlife
Two conservationists found the first black frogs in the area in 2016. They note that although oriental tree frogs are normally bright green in color, they said:
The deadliest nuclear accident in history happened around 60 kilometers north of the Ukrainian city of Kiev. The nuclear disaster allowed radiation to spread, which led to diseases and genetic changes in many other creatures in addition to frogs.
The majority of animal diseases have been shown to be lethal or extremely harmful, however frog skin darkening can be crucial. It shields the wearer from numerous radiation sources.
Pablo Burraco, a colleague of Orizaola, claims that “dark colour defends against numerous kinds of radiation.In the case of frogs, melanins, skin pigments prevalent in many species, are the cause of this glossy black colour.”
The melanin found in humans can protect against radiation. Melanin can neutralize ionized molecules inside the cell, such as reactive oxygen species, as well as absorb and reflect some of the radiation.
People exposed to radiation are less likely to sustain more cell damage as a result of these consequences, which also improve their odds of surviving. This implies that melanin-rich frogs have a higher chance of surviving.
The “final group” of dark black amphibians emerged as a result of the dark frogs‘ superior ability to reproduce through time compared to the green frogs.
Trying to determine whether some species can actually adapt to living in radiation-filled environments is one of the most fascinating study areas at Chernobyl. Radiation, like other contaminants, may be a highly strong selector, favoring species with adaptations that increase their survival in radioactive environments.
Over the past three years, researchers have examined the skin tones of more than 200 male frogs that they gathered in 12 separate ponds around the radioactively contaminated area.
They comprised four locations beyond the Chernobyl zone in addition to some of the most hazardous regions. The exclusion zone, which now restricts entry to the 1,000 square kilometers surrounding ground zero, may have helped the mutant frogs survive because of their black skin, according to scientists.
More than 10 generations of frogs have changed since the tragedy, even though a disaster can account for a relatively quick process of natural selection. Will black frogs continue to be the dominant species given that radiation levels are significantly lower now ? Or will the mutation create some other super power.
