Polar Bear/Grizzly Hybrid discovered in Northwest Territories.

a grizzly bear, polar bear hybrid was shot 2000 kilometers north of edmonton on banks island near nelson head in the north west territories. the animal is likely the result of a desperate grizzly male that had to lower his standards and mate with a polar bear female because he couldn't find a member of his own species to mate with. scientists beleive that this is more than likely not an isolated incident, as global warming continues and grizzly bears are moving farther north they are sharing territories with polar bears more frequently. animal hybridization in the wild is a common occurance. red wolves which are recognized as a distinct species are more than likely the descendants of coyotes and wolves. several hybrids of two different species are sterile because of the genetic differences of their parents, but because polar bears and grizzlies are so closely related it is more than likely that any hybrids would be fertile and able to reproduce.
