Human Endangerment

Humans were once an endangered species. About 1.2 million years ago, at a time when our ancestors were spreading through Africa, Europe, and Asia, there were probably only around 18,500 individuals capable of breeding. Humans faced another population bottleneck where the human population was reduced to less than 1000 people total around 70,000 years ago due to a supervolcano explosion in Indonesia that triggered a nuclear winter.
