Their future depends on reducing these pressures before resilience alone proves insufficient \u2013 as history already warned with the extinction of cave bears.<\/p>\n<p>What cave bear bones revealed<\/p>\n<p>The study was led by <a href=\"https:\/\/www.uclan.ac.uk\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">University of Central Lancashire<\/a>\u00a0archaeologist Dr. Jennifer Jones, along with colleagues from Spain, Serbia, and\u00a0<a href=\"https:\/\/www.ucl.ac.uk\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">University College London<\/a>. <\/p>\n<p>The team examined cave bear remains from \u0160alitrena Pe\u0107ina in Serbia. The bones, more than 40,000 years old, still held chemical traces of the bears\u2019 diets.<\/p>\n<p>The study overturned old assumptions, showing cave bears were flexible eaters. Instead of relying on one food, they consumed plants from forests, open landscapes, and even lichens. <\/p>\n<p>This adaptability should have improved their survival odds, yet environmental upheaval and human pressures proved stronger than their dietary range.<\/p>\n<p>Adaptable but not invincible<\/p>\n<p>During the last Ice Age, Europe\u2019s climate shifted dramatically, with colder temperatures, longer winters, and shrinking vegetation reduced food supplies.<\/p>\n<p>At the same time, humans expanded into their <a href=\"https:\/\/www.earth.com\/news\/brown-bears-move-where-their-food-grows\/\" rel=\"nofollow noopener\" target=\"_blank\">habitats<\/a>, competing for shelter and hunting bears. Neanderthals and modern humans occupied caves once essential for hibernation. <\/p>\n<p>Predators like hyenas further stressed populations by preying on vulnerable cubs. Each threat alone might have been manageable, but together they overwhelmed even a resilient species. <\/p>\n<p>The combination of climate stress, human pressure, and natural predation pushed cave bears past their survival threshold.<\/p>\n<p>Pressure from every side<\/p>\n<p>\u201cOur study found that cave bears were flexible and could adapt to local conditions, much more so than previously thought. But when large-scale climate change was combined with human expansion, even a resilient species couldn\u2019t cope,\u201d said Dr. Jones. <\/p>\n<p>\u201cThis should serve as a warning for us as we explore ways of protecting endangered bears today.\u201d<\/p>\n<p>Cave bears were strong, but they were not immune. Humans occupied caves, cut into their territory, and hunted them. The bears\u2019 story is not just about climate, but about pressure from every side.<\/p>\n<p>Modern bears at risk<\/p>\n<p>Today, six out of eight bear <a href=\"https:\/\/www.earth.com\/news\/grizzly-bears-help-huckleberries-thrive-in-a-changing-climate\/\" rel=\"nofollow noopener\" target=\"_blank\">species<\/a> face the same kind of squeeze. In Europe, only about 17,000 to 20,000 brown bears remain. They live across more than 20 countries, but in small, scattered groups. Some survive in mountains, others in forest patches, but few live in strong connected populations.<\/p>\n<p>Habitat loss, poaching, and conflict with humans keep pushing them back. Climate change adds new stress. Isolation weakens their genetic strength. Every problem stacks on top of the last. <\/p>\n<p>Groups like the\u00a0International Union for Conservation of Nature (<a href=\"https:\/\/www.iucn.org\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">IUCN<\/a>)\u00a0and the\u00a0<a href=\"https:\/\/www.worldwildlife.org\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">World Wildlife Fund<\/a>\u00a0track these populations and warn of their growing vulnerability.<\/p>\n<p>Lessons for bear survival<\/p>\n<p>The cave bear\u2019s extinction reveals that survival collapses under overlapping pressures, not a single cause. Climate, habitat loss, and human conflict together prove fatal. <\/p>\n<p>Today, brown bears and their relatives face the same dangerous mix, standing at a crossroads where combined threats could decide their future survival.<\/p>\n<p>\u201cWe need to recognize that adaptability isn\u2019t enough for bear species to survive, if the threats against them continue to mount,\u201d said Dr. Jones.  <\/p>\n<p>\u201cThe more pressure that we pile on today\u2019s wildlife like aggressive habitat loss, climate change and ongoing human conflicts, the smaller their chance of survival is.\u201d<\/p>\n<p>Urgent action needed to protect bears <\/p>\n<p>The past makes one point clear. Protecting today\u2019s bears means lifting some of the heavy weight. That includes bigger habitats, safer food sources, and less conflict with humans. <\/p>\n<p>The study on cave bear extinction shows what happens when every margin of survival is erased. If we want brown bears to endure, the time to act is now.<\/p>\n<p>Organizations like <a href=\"https:\/\/rewildingeurope.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Rewilding Europe<\/a>\u00a0already work to secure habitats and reconnect populations, but much more remains to be done.<\/p>\n<p>The study is published in the journal <a href=\"https:\/\/www.tandfonline.com\/doi\/full\/10.1080\/14614103.2025.2521944\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Environmental Archaeology<\/a>.<\/p>\n<p>\u2014\u2013<\/p>\n<p>Like what you read? <a href=\"https:\/\/www.earth.com\/subscribe\/\" rel=\"nofollow noopener\" target=\"_blank\">Subscribe to our newsletter<\/a> for engaging articles, exclusive content, and the latest updates.\u00a0<\/p>\n<p>Check us out on <a href=\"https:\/\/www.earth.com\/earthsnap\/\" rel=\"nofollow noopener\" target=\"_blank\">EarthSnap<\/a>, a free app brought to you by <a href=\"https:\/\/www.earth.com\/author\/eralls\/\" rel=\"nofollow noopener\" target=\"_blank\">Eric Ralls<\/a> and Earth.com.<\/p>\n<p>\u2014\u2013<\/p>\n","protected":false},"excerpt":{"rendered":"Extinction stories are not just about the past.
