Our DNA analysis of 75,000-year-old bones in Arctic caves reveals how animals responded to changing climates – New Study/Science Updates
As the Arctic warms faster than anywhere else on Earth, animals that have evolved to survive the cold face unprecedented challenges. While scientists are learning more about how modern wildlife responds to environmental change, we still know little about how species coped in the past.
Summary
The Arctic’s rapid warming poses significant challenges to its cold-adapted wildlife. Understanding how species are currently responding to these changes is crucial, but our knowledge of how animals survived past Arctic environmental shifts remains limited. Bridging this gap in our understanding of historical adaptation strategies is vital for predicting future impacts on Arctic ecosystems and informing effective conservation efforts. Studying past responses will equip us to better protect vulnerable species facing unprecedented environmental pressures in the rapidly changing Arctic.
