The Toba Eruption is recognized as one of our planet’s largest known eruptions. The related catastrophe hypothesis holds that this event caused a global volcanic winter of 6–10 years and possibly a 1,000 year-long cooling episode.
The Toba event is the most closely studied super-eruption. In 1993, science journalist Ann Gibbons suggested a link between the eruption and a bottleneck in human evolution, and Michael R. Rampino of New York University and Stephen Self of the University of Hawaii at Manoa gave support to the idea. In 1998, the bottleneck theory was further developed by
