According to the Toba catastrophe theory, the super-eruption caused a near-extinction of the human race. "The original Toba catastrophe theory relies on the 'classical' volcanic winter, i.e., on cooling and reduction of the precipitation as the main evolutionary factors to explain the . 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. So I was reading at Wikipedia this evening that "the Toba catastrophe theory, which postulates a population bottleneck for Homo sapiens about 70,000 years ago, was controversial from its first proposal in the 1990s and by the 2010s [it] had very little support." [1] That was news to me. Toba Catastrophe Theory is the idea that a population bottleneck in humanity's past, which is inferred from gene analysis, was caused by a supervolcano eruption 75,000 years ago on Lake Toba is what is now Indonesia.

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. In fact, this event led to the Toba catastrophe theory. The Toba catastrophe theory centres around a correlation, and a controversial one at that.
