In a cliff near Mossel Bay, a town on South Africa's south . At about the same time as the Toba volcano was blowing, all those millennia ago, our species was also going through a genetic bottleneck; the eruption seemed like a plausible cause for this drop in diversity. This sounds like an excellent event to teach us about the wide-spread and varied consequences of a catastrophic volcanic eruption. The Toba Catastrophe Theory was first proposed in 1998 by Stanley H.

[1] That was news to me. The "Toba catastrophe theory" is highly controversial, and other researchers have argued that it greatly overestimates both the degree of climate change that the volcano inflicted, and its effect on our ancestors.

Theories of catastrophes are great for analysing the causal effects of a disaster, but the real world provides a unique set of systems that cannot be adequately described by many of these theories. The eruption of Toba led to a volcanic winter with a worldwide decline in temperatures between 3-5 degrees C, and up to 15 degrees C in higher latitudes. If the Toba catastrophe theory was true and humans died in large numbers after its eruption, one would expect little or no signs of human activity in the period immediately following the eruption.
