Polar bears in southern Greenland are 'using jumping genes to rapidly rewrite their own DNA' to survive melting sea ice
SMRTR summary
Polar bears in southern Greenland are activating "jumping genes" that rapidly alter their DNA in response to rising temperatures and melting sea ice. These transposable elements are changing genes related to heat stress, metabolism, and fat processing, potentially helping the isolated population adapt to warmer conditions than their northern counterparts.
