The most recent and widespread migration of humans out of Africa, which occurred less than 1,00,000 years ago, may have taken place during a particularly arid period following the Toba supervolcano eruption in Indonesia, a new study published in the journal Nature suggests.
It is typically thought that the dispersals of humans out of Africa occurred during humid periods that created ‘green corridors’ and facilitated the movement of people. Periods of aridity are thought to have constrained human movement and created food insecurity.
