A recent theory for this event hypothesizes that the ability to consume acetate increased Methanosarcina microbe populations, causing a global rise in (*) carbon dioxide levels.
The Wilkes Land mass concentration in Antarctica is hypothesized to be evidence for a cause of this event. A recent theory for this event hypothesizes that the ability to consume acetate increased Methanosarcina microbe populations, causing a global rise in (*) carbon dioxide levels. This was the only event of its type to affect insects. The major hypothesis for this event involves a mantle plume that caused unprecedented volcanism over a period of a million years in present-day Siberia. For 10 points, name this most severe of Earth's mass extinction events that occurred between the Permian and Triassic periods.
