Neandertals didn’t get dumped on prehistory’s ash heap — it got dumped on them. At least three volcanic eruptions about 40,000 years ago devastated Neandertals’ western Asian and European homelands, spurring a rapid demise of these humanlike hominids, says a team led by archaeologist Liubov Golovanova of the ANO Laboratory of Prehistory in St. Petersburg, Russia.
Modern humans survived because they lived in Africa and on the tip of southwestern Asia at that time, safely outside the range of volcanic ash clouds, Golovanova’s group proposes in the October Current Anthropology. If that scenario pans out, then geographic good luck allowed Homo sapiens to move into Neandertals’ former haunts after a couple thousand years without having to compete with them for food and other resources, as many researchers have assumed.
Advances in stone toolmaking and other cultural innovations achieved by modern humans shortly after 40,000 years ago supported survival in harsh, postvolcanic habitats, Golovanova and his colleagues hypothesize.
