I can’t help but think this is nature’s way of adapting to the global temperature changes and the melting of the polar ice. A hybrid allows the polar bears to migrate farther south to warmer areas and avoid going extinct (at least as far as they can be genetically traced back to ‘true’ polar bears). This of course all comes about because the polar bears are being forced farther south to begin with (and/or grizzlies are able to migrate farther north) so it creates a perfect meeting ground for both species and bam, cross-breeding for evolutionary adaptation :)
