The most large-scale mass extinction for the last 540 million years has destroyed over 90% of marine species and 75% of land. Although scientists had a hypothesis that the reason for this event, which occurred at the end of the Perm period, was the eruption of volcanoes on the territory of modern Siberia, they could not explain how this led to the livestock extinction and on land and the sea. Explanation found biologists and chemists from the USA, China, Canada and Switzerland.

An international team of scientists has published the results of analyzing nickel isotopes in sedimentary rocks collected in the Canadian Arctic,

Nickel is present in the body of many living beings, but the excess of a certain amount leads to the explosive growth of the activity of methano-producers, microorganisms producing methane. Increasing the level of this gas has an extremely malicious effect on all oxygen-dependent forms of life.

Prior to this discovery, scientists had no evidence of communication between basalt vulcanism of Siberian trappes, a lack of oxygen in marine organisms and mass extinction. The answer to the long-standing riddle allows you to better understand the geochemical processes and transport of metals in the environment.

Scientists know that most of the types of living organisms ever existed on Earth extinct. The process of mass extinction was equalized as an equally massive growth of taxonomic diversity during the so-called evolutionary radiation. However, Japanese researchers
