About the same time the eruption took place, the number of modern humans apparently dropped cataclysmically, as shown by genetic research. People today evolved from the few thousand survivors of whatever befell humans in Africa at the time. The giant plume of ash from Toba stretched from the South China Sea to the Arabian Sea, and in the past investigators proposed the resulting volcanic winter might have caused this die-off.

However, recently scientists have suggested that Toba did not sway the course of human history as much as previously thought. For instance,prehistoric artifacts discovered in India and dating from after the eruption hinted that people coped fairly well with any effects of the eruption.
Now researchers have found that the evidence shows Toba didn't actually cause a volcanic winter in East Africa where humans dwelled.
"We have been able to show that the largest volcanic eruption of the last two million years did not significantly alter the climate of East Africa," said researcher Christine Lane, a geologist at the University of Oxford.
