The reactor accident released the most radioactive material in human history that completely changed this region of Ukraine. People could no longer live there, apart from animals, that are able to survive there. Another thing we all know is that radiation is dangerous. It is because it can develop undesirable mutations in living organisms. Scientists are trying to detect species that are capable to adapting to the radiation. Melanin wich is responsible for the colours of organism even humans, (hair & eyes) happened to reduce negative effects of radiation. In 2016 the first black frogs were discovered and scientist started to study how melanin helps to live in this region. Their work reveals that tree frogs living all over the chernobyl contamination zone are slighly more or pitch black. Studies suggest that the colour of their skin is a process of evolution ...
