Cave bears were giant plant eating bears that roamed Europe and northern Asia, and went extinct around 25 thousand years ago. They hibernated in caves during the winter. This was a dangerous time, as those which had failed to fatten up enough during the summer would not survive hibernation.
As a result, many caves across Europe and northern Asia are now filled with the bones of cave bears, each one containing potentially thousands of individuals. In our new study, we analysed a bone from a cave in the Caucasus Mountains.
Our team recovered the genome from a 360,000-year-old…
