A major population decline began 195,000 years ago

Ironically, the dust cycles have already been closely linked with the near extinction of humanity, by the harshness of their effects that make the cold of the Ice Age still colder. Archeology tells us a major population decline began roughly 195,000 years ago, which coincides with the first major dust spike in that period. The resulting dust-cooled period is termed in archeology the Marine Isotope Stage 6. It is believed that the human population diminished dramatically during this period, from more than 10,000 adult individuals to as low as just a few hundred. It is believed that the major population bottleneck occurred in the period after 165,000 years ago until the technology was developed to live of the sea.
