What is the lowest number of human population in history?
No, not two as in Adam and Eve! The lowest number from genetic studies suggest somewhere between 3,000 to 10,00 people.
Around 70,000 years ago, a supergiant volcanic eruption in Indonesia caused a global cooling event that may have lasted up to 1,000 years. This would have caused a catastrophic collapse in human, and many other species, on Earth. The human population would have been around 3,000 to 10,000 people. Most people alive today can trace their lineage back to these few thousand human survivors!
