Humans Hunted and Butchered the Mighty Cave Bear into Extinction
At 3.5 meters long and with a shoulder height of 1.7 meters, the cave bear was one of the giants of the Ice Age. Yet few appear to have survived until the last glacial maximum 24,000 to 19,000 years ago. Researchers from Germany, Italy and Canada have conducted analyses to find out what likely caused the extinction of these large herbivores.
In several regions of Europe, cave bears disappeared well before the start of the last glacial maximum. However, some cave bear populations seem to have survived until 24,000 years ago – with one in northeastern Italy whose more recent dates suggest it was the last to die out. The researchers used bones from that location for the current study. They dated the bones using the latest methods and compared the bears’ diet with that of older populations. They also looked for signs of hunting and butchery by humans.
The new radiocarbon dating confirmed that these cave bears lived as late as 24,000 years ago, after the start of the last glacial maximum. The bones also revealed evidence of hunting and butchery by humans. Isotopic analyses showed that the bears still did not eat meat, despite the colder climate. Hervé Bocherens suggests this lack of adaptability and the pressures of hunting by humans may have increased the stress on the cave bears ‒ such that they could no longer survive in a harsher climate. “It was likely this combination of climatic and anthropogenic factors which led to their extinction,” he says.
