Polar bears in southern Greenland are 'using jumping genes to rapidly rewrite their own DNA' to survive melting sea ice
PositiveScience
- Recent studies indicate that polar bears in southern Greenland are undergoing genetic mutations, utilizing jumping genes to adapt to the rapidly changing environment caused by melting sea ice. This adaptation is crucial for their survival as climate change intensifies.
- The ability of polar bears to rewrite their DNA in response to environmental stressors highlights the resilience of wildlife in the face of climate change. This finding underscores the importance of genetic research in understanding how species can survive in increasingly hostile conditions.
- The genetic changes observed in polar bears reflect broader ecological shifts as warming temperatures impact marine ecosystems and ocean currents. Concerns about the Atlantic Meridional Overturning Circulation's stability further emphasize the interconnectedness of climate systems and the urgent need for conservation efforts to protect vulnerable species.
