Morgen seid ihr alle tot. Denn sie kommen!

Es ist schon einmal geschehen, es kann jederzeit wieder geschehen.

Waren Mikroben schuld am Massenaussterben?

„Rothman and his colleagues have identified a different culprit — one coming from biology rather than geology. They argue in the Proceedings of the National Academy of Sciences that the carbon disruption and, consequently, the end-Permian extinction were set off by a particular microorganism that evolved a new way to digest organic material into methane.

With this genetic innovation, these methane-producers, or methanogens, ran rampant across the ocean, overturning the carbon cycle. The resulting changes in ocean chemistry would have driven many species to extinction.“
