One of the largest eruptions in Earth’s history could have wiped out humans. Here’s how scientists say some survived
By piecing together clues from the fossils and artifacts found at the site, along with geological and molecular analysis, the team began to understand how the humans living there forged ahead despite the likely climate shift that the volcanic cataclysm triggered. An analysis of the site’s flora and fauna also found an abundance of fish remains in the aftermath of the eruption. The finding is perhaps not surprising given how near the site was to the river, but fish are rare in other Stone Age sites from the same period, the study noted.
The team theorized that the drier climate, counterintuitively, explains the increased reliance on fish: As the river shrank, fish were trapped in water holes or shallower streams that hunters could more easily target.The fish-rich water holes may have potentially created what the team described as a “blue corridor,” along which early humans moved north out of Africa once they were depleted of fish.
“We can do that by just looking at the cobbles,” Kappelman said. “A very energetic river can move bigger boulders and cobbles than a river that isn’t that What we find for the ancestor river are smaller than the river today.” “The authors also highlight very clear indicators suggesting the existence of archery here 74,000 years ago,” Slimak said. “There is therefore every reason to … consider these ancient Homo sapiens as bearers of already highly advanced technologies, largely emancipated from natural and climatic constraints, crucial factors for understanding their migrations later on, across all continents and under all latitudes.
