Toba Eruption, Human Bottleneck Theory

The provided text discusses the Toba supereruption and its impact on human history, specifically challenging the Toba Catastrophe Theory. This theory posited that around 74,000 years ago, a massive volcanic event in Sumatra caused a global "volcanic winter" and nearly wiped out humanity, leading to a severe genetic bottleneck. However, the source argues that new evidence from paleoclimatology, archaeology, and genetics has largely refuted this idea, showing no widespread volcanic winter and instead demonstrating human resilience and continuous occupation in affected regions. The text concludes that the Toba event, rather than causing a near-extinction, acted as an evolutionary filter, highlighting human adaptability and ingenuity.
