Fascinating and Strange Facts About Evolution and Early Humans

Uncertain Future

The human population has experienced exponential growth. It took 100,000 years to reach one billion people, but subsequent billions were added much more rapidly. Ecologists predict that the world population will reach eight billion by 2025.

Around 70,000 BC, a mysterious illness, possibly tuberculosis, drastically reduced the population to approximately 2,000 individuals. This event placed early humans in a precarious position, similar to endangered species like black rhinos and giant pandas. The future remains uncertain for our species.
