From research conducted on the Somali Peninsula, evidence has been found indicating that humans during the Middle Stone Age survived after the eruption of Mount Toba. This evidence was discovered by scientists from the University of Texas in their recent study published in Nature, which suggests that humans spread or expanded during dry intervals along the blue-colored highway by seasonal rivers. The researchers also found stone tools, which are the oldest evidence of archery from that time.

Not only that, humans living in that era have tried to expand into Africa several times. However, the occurrence of the great eruption caused global expansion to occur less than 100 thousand years ago. Therefore, some researchers have hypothesized that the spread was limited. The spread was in an area called the 'Green Corridor' and formed during a humid period when food supplies were abundant and human populations grew in line with their environment.

John Kappelman, as a professor of anthropology and geology at the University of Texas and the main panelist of the study, revealed that the fragments found were smaller than the diameter of a human hair. With such a small size, John assessed that the fragments were still large enough to analyze their chemical composition and elements. "These fragments are smaller than the diameter of a human hair. Even at that small size, they are still large enough to analyze their chemical composition and elements," said John through the journal Nature quoted from arkeonews.net.

It is known that a major eruption occurred when the site in Ethiopia was visited by humans with evidence of small glass fragments whose chemical content matched that of Mount Toba. The impact is that the climate produced after the eruption is a long dry season and causes people in the area to rely on fish as their food supply. As time goes on, the dry season causes water puddles to shrink and pushes people to migrate to the next place to seek more food supplies.

Although finding many evidence, some researchers suspect that the volcanic winter had a significant impact on life and wiped out most of the ancient humans due to genetic evidence showing a sharp decline in the human population. Recent research by researchers at an archaeological site in northwest Ethiopia adds new evidence that the event was not as 'catastrophic' as it seems. Report: Nisya Aprilya
