Disproved the myth about the extinction of humanity because of the volcano

Опровергнут миф о вымирании человечества из-за супервулканаThe human population should not have to suffer from Toba.

Scientists at Arizona state University found that the eruption of the SUPERVOLCANO Toba about 74 thousand years ago has not led to the extinction of humanity as previously thought. Article scientists published in the Journal of Human Evolution. About it reported in a press release on the website Phys.org.

According to the current hypothesis, the eruption of Toba on the island of Sumatra led to the cold, the sulphur emissions into the atmosphere and acid rain, which destroyed the vegetation in East Africa and they have caused damage even in North America. With the huge layer of volcanic sediments have covered Southeast Asia, China and India.

According to the theory of the “bottleneck”, the number of the African population at this time was reduced from 100 to 10 thousand, that is, humanity has died out almost completely.

Researchers from Arizona studied vitality — fossilized plant remains in the sediments of lake Malawi (Africa), whose age covers a period of 100 years before the Toba eruption and 200 years after the disaster. Experts have not found significant changes in the composition of vegetation, which could indicate a volcanic winter. Was detected some signs of the disappearance of mountain plants, are vulnerable to relatively small cold.

According to scientists, the human population should not have to suffer from Toba, as settlements were in the foothills, where the decrease in air temperature probably was not significant.
