The study, conducted by scientists from the Max Planck Institute for Chemistry<\/a>, KAUST<\/a>, and the King Saud University<\/a>, has discovered that the eruption of Indonesia\u2019s Topa supervolcano drastically impacted the Earth\u2019s atmospheric ozone levels between 60,000 to 100,000 years ago.<\/p>\n The researchers believe that their findings can help to elaborate on why ancient human population levels declined, concluding a long-debated evolutionary puzzle.<\/p>\n Sergey Osipov, the leader of the study from the Max Planck Institute for Chemistry, said: \u201cToba has long been posited as a cause of the bottleneck, but initial investigations into the climate variables of temperature and precipitation provided no concrete evidence of a devastating effect on humankind.\u201d<\/p>\n \u201cWe point out that, in the tropics, near-surface ultraviolet (UV) radiation is the evolutionary driving factor. The climate becomes more relevant in the more volatile regions away from the tropics,\u201d commented KAUST\u2019s Georgiy Stenchikov.<\/p>\n
