10 Prehistoric Deadly Events That Changed Human History

All right, let's go. Number 10, the Toba supereruption and the genetic bottleneck.
Approximately 74,000 years ago, on the island now called Sumatra, the Earth itself opened up. A volcano named Toba erupted with a force that defies comprehension, releasing an estimated 2,800 cubic kilometers of magma in a single catastrophic event. To put that number in perspective, the 1980 eruption of Mount St. Helens released about one cubic kilometer of material. Toba released nearly three thousand times more. It remains the largest volcanic eruption of the last 2 million years, and when it happened, our ancestors were there to witness it.
