Just as Toba nearly drove humans to extinction 73,000 years ago, data suggests Neanderthals did actually become extinct from volcanic climate change 40,000 years ago, due to the Campanian Ignimbrite, a super volcano near Naples. The Heinrich Event 4, a cooling period associated with the Campanian Ignimbrite, lasted 250 years.
Toba catastrophe theoryConstraints on the duration and freshwater release of Heinrich event 4 through isotope modellingScienceDaily (Oct. 7, 2010) — New research suggests that climate change following massive volcanic eruptions drove Neanderthals to extinction and cleared the way for modern humans to thrive in Europe and Asia.
The research, led by Liubov Vitaliena Golovanova and Vladimir Borisovich Doronichev of the ANO Laboratory of Prehistory in St. Petersburg, Russia, is reported in the October issue of Current Anthropology.
"
e offer the hypothesis that the Neanderthal demise occurred abruptly (on a geological time-scale) … after the most powerful volcanic activity in western Eurasia during the period of Neanderthal evolutionary history," the researchers write. "his catastrophe not only drastically destroyed the ecological niches of Neanderthal populations but also caused their mass physical depopulation."
Evidence for the catastrophe comes from Mezmaiskaya cave in the Caucasus Mountains of southern Russia, a site rich in Neanderthal bones and artifacts. Recent excavations of the cave revealed two distinct layers of volcanic ash that coincide with large-scale volcanic events that occurred around 40,000 years ago, the researchers say.
