The grizzly bear (Ursus arctos horribilis, horribilis means "horrible" in Latin) is a very large brown bear living in North America. All of this could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced.

In cross-section, the hair of polar bears is hollow, while the hair of grizzlies is either solid or has small hollow regions. And with that growing contact between the two species comes more mating, and therefore increased sightings of their hybrid offspring. New York, According to DeSantis, generalist animals such as coyotes and cougars are the best survivors of rapid change to their environment, not highly specialized apex predators like polar bears and saber-toothed cats. Theres no way of telling for sure, but they didnt entirely rule out either bear being a hybrid. Polar bears and brown bears also overlap around the Beaufort Sea in the western Canadian Arctic.
