A supervolcano eruption, believed to have occurred around 74,000 years ago, may have had a significant impact on human history. The eruption, which is thought to be one of the largest in human history, potentially threatened the survival of the human species, but humans apparently found a way to survive. The effects of the eruption on human migration and evolution are still being studied and debated, with some research suggesting it may have facilitated humanity's migration out of Africa.
