Scientists at mit have found a link between the large-scale extinction of all time, occurred 252 million years ago, and the process of reproduction of methane-producing bacteria. The data were published in the scientific journal Proceedings of the National Academy of Sciences (PNAS).
Researchers agree that the archaea Methanosarcina or their relatives were the main cause of the mass extinction of species on planet Earth. To prove their theory, scientists have recreated the biological model. It turned out that the volume of methane produced by bacteria, were so great that it resulted in the death of animals and plants.
Note that one of the theories Permian extinction tied to frequent acid rain that occurred 252 million years ago. Scientists believe that up to 95% of all life died during this period.
Chinese experts also suggest that the death of all living things connected with the processes surrounding the split of Pangaea.
