200,000 Years Ago: How Our Ancestors Survived the Impossible | History for Sleep

200,000 Years Ago: How Our Ancestors Survived the Impossible | History for Sleep Around 70,000 years ago, we almost went extinct. Human population crashed from maybe a million people to somewhere between 3,000 and 10,000 individuals. Everyone left on Earth could fit in a small town. Mount Toba in Indonesia erupted—the largest volcanic event in two million years. Ash hit the stratosphere. Temperatures dropped by 15 degrees Celsius for six years. Volcanic winter. Crops failed, animals died, water froze. Somehow we survived. This episode explores how they made it through six years of darkness, why we have less genetic diversity than chimps, and what happened to the other human species like Neanderthals and Denisovans who didn't make it.
