Imagine stumbling on a cave packed with 75,000-year-old animal bones—like lemmings, whales, and even a polar bear! That’s what scientists found in Norway, revealing a lost Arctic ecosystem that totally vanished when the glaciers took over. The wildest part? These cold-loving creatures couldn’t survive the big freeze, and their ancient DNA is nothing like what’s in today’s Arctic animals. It’s a chilling reminder of how climate change can wipe out entire worlds. #Science #IceAge #Arctic
