Super Toba volcano 70,000 years ago did not have disastrous consequences

According to an international study published in Science , the most powerful volcanic eruption in Earth history in Toba (Indonesia) about 70,000 years ago has left no disastrous consequences for climate and evolution. of people compared to previously thought.

Dr. Michael Petraglia of the University of Cambridge (UK) led the study and colleagues discovered many stone tools in an area in southern India proving that local residents stayed in the area after the eruption in Toba.

Other tools and traces were found in sediments above and below the volcanic ash layer. The researchers noted that the tools in the second layer of sediment had a slight change from the tools before the eruption but kept the same characteristics.

This proves that the impact of volcanic activity on humans is not as serious as some previous assumptions. However, the scientists said they would do more research to confirm the results.

They also affirmed that this finding could help to better understand the characteristics of migration at the time, because the sophistication of the discovered stone tools could prove they were built. by modern people instead of progressive evolution.
