MIT researchers have found evidence that methane-producing microbes may have triggered the largest mass extinction in Earth’s history, reports Will Dunham for Reuters.

Nature reporter Chelsea Ward reports that a team from MIT led by Professor Daniel Rothman has found that, “Methane-belching microbes may have been behind the 'Great Dying', a mass-extinction event that wiped out some 90% of all species on Earth about 252 million years ago.”

The Guardian highlights new research by Professor Daniel Rothman that suggests microbes may be responsible for the end-Permian extinction. As reported by The Guardian, “Analysis of geological carbon deposits reveals a significant boost in levels of carbon-containing gases – either carbon dioxide or methane – at the time of the mass extinction.”
