"The fact that humans are about 99.9% genetically identical could, according to one theory, be traced back to the Toba eruption in Indonesia roughly 70,000 years ago. That eruption might have killed off most of the human race, leaving only a few hundred of us to populate the planet. We might, therefore, owe our evolution and very existence to volcanoes."
