The Primitive Toba Catastrophe Theory
The Toba supereruption was a supervolcanic eruption that occurred at the site of present-day Lake Toba in Sumatra, Indonesia. It was estimated to have caused a global volcanic winter of six to ten years along with a 1,000-year-long cooling episode. It spewed roughly 1,000 times as much rock as the famous 1980 eruption of Mt St Helens.
The Stone Tools that Changed It
Archaeologist Chris Clarkson from the University of Queensland, explains how populations at Dhaba were using stone tools that were similar to the toolkits being used by Homo sapiens in Africa at the same time. Both were developed by them to modify their respective environments and the results confirm how humans migrated out of Africa and expanded across Eurasia much earlier than expected, surviving a natural calamity in the meantime.
If the Volcano Didn’t Get Them, What Did?
Geneticists agree that back then, there was an unmistakable drop in human genetic diversity, but that shift could be a founder effect. However, without human fossils to back up the findings, there are some who remain unconvinced these tools were made by Homo sapiens. Further studies would be done by scientists to create new archaeological records in times ahead so that a solid reason comes out behind the supereruption.
