> But the isolated sub-population has found a way to hunt without sea ice. The group, consisting of 27 adult females, has adapted to hunting on the ice that has calved off glaciers — called glacial mélange. The research team used genetic analysis to learn that this population has been isolated from other polar bear populations along Greenland’s east coast for at least 200 years. Well, that might give them a few extra generations but it sounds like a recipe for mutational meltdown in the long run https://en.wikipedia.org/wiki/Mutational_meltdown https://en.wikipedia.org/wiki/Mutational_meltdown
